Filtering on asp gridview headers using dropdowns on multiple columns

So I tried to added multiple filters for the gridview and I populated the dropdowns with the distinct datas of the column, but it gives me an exception, System.ArgumentException: Parameter 'siteValue' not found in the collection. I've added the mysql stored procedure along with the below code.
<asp:GridView ID="gdvTM" runat="server" AutoGenerateColumns="False" AllowPaging="true" OnPageIndexChanging="gdvTM_PageIndexChanging" DataKeyNames="ID" PageSize="10" CssClass="cssgridview" AlternatingRowStyle-BackColor="#d5d8dc" >
<Columns >
<asp:TemplateField HeaderText="Agent login">
<ItemTemplate>
<asp:Label ID="lbllogin" runat="server" Text='<%# Eval("agentlogin") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField >
<HeaderTemplate>
Site:
<asp:DropDownList ID="ddlgvsite" runat="server" OnSelectedIndexChanged="DropDownChange" AutoPostBack="true" AppendDataBoundItems="true">
</asp:DropDownList>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblsite" runat="server" Text='<%# Eval("site") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<HeaderTemplate>
Skill:
<asp:DropDownList ID="ddlgvskill" runat="server" OnSelectedIndexChanged="DropDownChange" AutoPostBack="true" AppendDataBoundItems="true">
</asp:DropDownList>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="lblskill" runat="server" Text='<%# Eval("skill") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Shift">
<ItemTemplate>
<asp:Label ID="lblshift" runat="server" Text='<%# Eval("shift") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="TM">
<ItemTemplate>
<asp:Label ID="lbltm" runat="server" Text='<%# Eval("tm") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="GrpM">
<ItemTemplate>
<asp:Label ID="lblGrpM" runat="server" Text='<%# Eval("grpM") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="OpsM">
<ItemTemplate>
<asp:Label ID="lblOpsM" runat="server" Text='<%# Eval("opsM") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Leave type">

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date">
<ItemTemplate >

</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Time">
<ItemTemplate>
<asp:Label ID="lbltime" runat="server" Text='<%# Eval("time") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Reason" ControlStyle-Width="300px">
<ItemTemplate>
<asp:Label ID="lblreason" runat="server" Text='<%# Eval("reason") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
Below would be the server side codes
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGrid();
}
}
private void BindDropDownList()
{
TableCell cells = gdvTM.HeaderRow.Cells[0];
PopulateDropDown((cells.FindControl("ddlgvsite") as DropDownList), (cells.FindControl("lblsite") as Label).Text);
PopulateDropDown((cells.FindControl("ddlgvskill") as DropDownList), (cells.FindControl("lblskill") as Label).Text);
}
private void PopulateDropDown(DropDownList ddl, string columnName)
{
ddl.DataSource = BindDropDown(columnName);
ddl.DataTextField = columnName;
ddl.DataValueField = columnName;
ddl.DataBind();
ddl.Items.Insert(0, new ListItem("Please Select", "0"));
}
private void BindGrid()
{
DataTable dt = new DataTable();
String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
MySqlConnection con = new MySqlConnection(strConnString);
MySqlDataAdapter sda = new MySqlDataAdapter();
MySqlCommand cmd = new MySqlCommand("GetApprovedData");
cmd.CommandType = CommandType.StoredProcedure;
if (ViewState["Site"] != null && ViewState["Site"].ToString() != "0")
{
cmd.Parameters.AddWithValue("#siteValue", ViewState["Site"].ToString());
}
if (ViewState["Skill"] != null && ViewState["Skill"].ToString() != "0")
{
cmd.Parameters.AddWithValue("#skillValue", ViewState["Skill"].ToString());
}
cmd.Connection = con;
sda.SelectCommand = cmd;
sda.Fill(dt);
gdvTM.DataSource = dt;
gdvTM.DataBind();
this.BindDropDownList();
TableCell cell = gdvTM.HeaderRow.Cells[0];
setDropdownselectedItem(ViewState["Site"] != null ? (string)ViewState["Site"] : string.Empty, cell.FindControl("ddlgvsite") as DropDownList);
setDropdownselectedItem(ViewState["Skill"] != null ? (string)ViewState["Skill"] : string.Empty, cell.FindControl("ddlgvskill") as DropDownList);
}
private void setDropdownselectedItem(string selectedvalue, DropDownList ddl)
{
if (!string.IsNullOrEmpty(selectedvalue))
{
ddl.Items.FindByValue(selectedvalue).Selected = true;
}
}
protected void DropDownChange(object sender, EventArgs e)
{
DropDownList dropdown = (DropDownList)sender;
string selectedValue = dropdown.SelectedItem.Value;
switch (dropdown.ID.ToLower())
{
case "ddlgvsite":
ViewState["Site"] = selectedValue;
break;
case "ddlgvskill":
ViewState["Skill"] = selectedValue;
break;
}
this.BindGrid();
}
private DataTable BindDropDown(string columnName)
{
String strConnString = System.Configuration.ConfigurationManager.ConnectionStrings["connStr"].ConnectionString;
MySqlConnection con = new MySqlConnection(strConnString);
MySqlCommand cmd = new MySqlCommand("SELECT DISTINCT " + columnName + " FROM approved WHERE " + columnName + " IS NOT NULL", con);
MySqlDataAdapter sda = new MySqlDataAdapter(cmd);
DataTable dt = new DataTable();
sda.Fill(dt);
return dt;
}
protected void gdvTM_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gdvTM.PageIndex = e.NewPageIndex;
this.BindGrid();
}
Below would be the MySql stored procedure
CREATE DEFINER=`root`#`localhost` PROCEDURE `GetApprovedData`
(in siteValue varchar(45), in skillValue varchar(100))
BEGIN
select *
from approved
where site = siteValue or siteValue is null and
skill = skillValue or skillValue is null;
END
Please let me know what I'm doing wrong. Thanks in advance....

1) You have to changes your stored procedure like
CREATE DEFINER=`root`#`localhost` PROCEDURE `GetApprovedData`(in siteValue varchar(45),
in skillValue varchar(100))
BEGIN
IF siteValue IS NULL and skillValue IS NULL THEN
select * from approved;
ELSEIF siteValue IS NULL and skillValue IS NOT NULL THEN
select * from approved where skill = skillValue;
ELSEIF siteValue IS NOT NULL and skillValue IS NULL THEN
select * from approved where site = siteValue;
ELSE
select * from approved where site = siteValue and skill = skillValue;
END IF;
END
2) In your BindGrid function make the changes below
private void BindGrid()
{
//Your rest of code is same here
string siteValue = null;
string skillValue = null;
if (ViewState["Site"] != null && ViewState["Site"].ToString() != "0")
{
siteValue = ViewState["Site"].ToString();
}
if (ViewState["Skill"] != null && ViewState["Skill"].ToString() != "0")
{
skillValue = ViewState["Skill"].ToString();
}
cmd.Parameters.AddWithValue("siteValue", siteValue);
cmd.Parameters.AddWithValue("skillValue", skillValue);
//Your rest of code is same here
}

Gridview Footer Not an Instance

I'm trying to get an Automatic ID filler for a gridview footer text box, but every time I run I get the "Not Referred Instance of an object" meaning the method isn't finding the Text box, Right?
But I have the same text box in other method and is working correctly, what its wrong?
Below is the code sample of GridView
<asp:GridView ID="GridView1" runat="server" BackColor="#CCCCCC" BorderColor="#999999" BorderStyle="Solid" BorderWidth="3px" CellPadding="4" CellSpacing="2" ForeColor="Black" AutoGenerateColumns="False" ShowFooter="True">

Below is the code sample for binding the grid in code behind

using (SqlCommand cmd = new SqlCommand(sql, conn))
{
using (SqlDataAdapter ad = new SqlDataAdapter(cmd))
{
ad.Fill(table);
}
}
}
IncrementoID();
GridView1.DataSource = table;
GridView1.DataBind();
}
protected void Agregar_Click(object sender, ImageClickEventArgs e)
{
connStr.Open();
GridViewRow row = GridView1.FooterRow;
TextBox txtNombre = (TextBox)row.FindControl("txtNombre");
string str = "select count(nombre) from unidades where nombre like '"+txtNombre.Text+ "'";
SqlCommand com = new SqlCommand(str,connStr);
int count = Convert.ToInt32(com.ExecuteScalar());
connStr.Close();
if (count > 0)
{
string script = "alert('Este Nombre ya Existe.','Atención');";
ScriptManager.RegisterStartupScript(this, this.GetType(), "testScript", script, true);
}
else
{
connStr.Open();
TextBox txtID = (TextBox)row.FindControl("txtAddID");
CheckBox chkFracc = (CheckBox)row.FindControl("chkFraccion");
TextBox txtClave = (TextBox)row.FindControl("txtClave");
string ID = txtID.Text;
string Nombre = txtNombre.Text;
bool Fracc = chkFracc.Checked;
string clave = txtClave.Text;
string query2 = "Insert into unidades values('" + ID + "','" + Nombre + "','" + Fracc + "','" + clave + "')";
SqlCommand cmd2 = new SqlCommand(query2, connStr);
cmd2.ExecuteNonQuery();
connStr.Close();
llenagrid();
IncrementoID();
}
}
public void IncrementoID()
{
//query = "select Count(id_unidad) from unidades";
//con.Open();
//SqlCommand cmd = new SqlCommand(query, con);
//string cid = cmd.ExecuteScalar().ToString();
//con.Close();
//TextBox ID = (TextBox)GridView1.FooterRow.FindControl("txtAddID");
//ID.Text = countid + (int.Parse(cid) + 1);
//ID.ReadOnly = true;
con.Open();
SqlCommand cmd = new SqlCommand("select MAX (CAST( ID_UNIDAD as INT)) from unidades",con);
SqlDataReader rd = cmd.ExecuteReader();
TextBox txtID = ((TextBox)GridView1.FooterRow.FindControl("txtAddID"));
if (rd.Read())
{
string Value = rd[0].ToString();
if (Value == "")
{
txtID.Text = "1";
}
else
{
txtID.Text = rd[0].ToString();
txtID.Text = (Convert.ToInt64(txtID.Text) + 1).ToString();
}
}
con.Close();
}
}
As you can see, in the insert method it finds the gridview textbox (txtAddID) and when I try to use the same exact syntax in the IncrementoID Method it doesn't work.

Here is the problem in the method llenagrid(), before binding GridView you are trying to access the control that are in Gridview (inside method IncrementoID), So it's giving error as Not Referred Instance of an object means the Object you are trying to access is not yet referenced. Below code sample can help you out:
public void llenagrid()
{
DataTable table = new DataTable();
using (SqlConnection conn = new SqlConnection(connStrr))
{
string sql = "SELECT id_unidad, nombre, fracciones, clave_sat from unidades";
using (SqlCommand cmd = new SqlCommand(sql, conn))
{
using (SqlDataAdapter ad = new SqlDataAdapter(cmd))
{
ad.Fill(table);
}
}
}
//IncrementoID(); // Remove the function call from here
GridView1.DataSource = table;
GridView1.DataBind();
IncrementoID(); // Call the function after GridView got binded.
}

SqlParameter paramEmail = new SqlParameter("#Email", Email);
cmd.Parameters.Add(paramEmail);
SqlParameter paramPhoneNumber = new SqlParameter("#PhoneNumber", PhoneNumber);
con.Open();
return cmd.ExecuteNonQuery();
}
}
}
}
I am able to perform select query .
I can not perform Create ,Delete or Update .

It seems like the phone number parameter is not on the cmd command

Here is how i got it to work
1) First i deleted event GridView1_DataBound
Delete "CommandField" column from GridView1 (markup)
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
2) insert this markup in its place
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lbEdit" CommandArgument='<%# Eval("EmployeeId") %>' CommandName="EditRow" ForeColor="#8C4510" runat="server">Edit</asp:LinkButton>
<asp:LinkButton ID="lbDelete" CommandArgument='<%# Eval("EmployeeId") %>' CommandName="DeleteRow" ForeColor="#8C4510" runat="server" CausesValidation="false">Delete</asp:LinkButton>
</ItemTemplate>
<EditItemTemplate>
<asp:LinkButton ID="lbUpdate" CommandArgument='<%# Eval("EmployeeId") %>' CommandName="UpdateRow" ForeColor="#8C4510" runat="server">Update</asp:LinkButton>
<asp:LinkButton ID="lbCancel" CommandArgument='<%# Eval("EmployeeId") %>' CommandName="CancelUpdate" ForeColor="#8C4510" runat="server" CausesValidation="false">Cancel</asp:LinkButton>
</EditItemTemplate>
</asp:TemplateField>
3) insert this FooterTemplate of EmployeeId
Insert
4) Now generate GridView1_RowCommand() event handler method.
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "EditRow")
{
int rowIndex = ((GridViewRow)((LinkButton)e.CommandSource).NamingContainer).RowIndex;
GridView1.EditIndex = rowIndex;
BindGrid();
}
else if (e.CommandName == "DeleteRow")
{
BAL.bal.DeleteCustomers(Convert.ToInt32(e.CommandArgument));
BindGrid();
}
else if (e.CommandName == "CancelUpdate")
{
GridView1.EditIndex = -1;
BindGrid();
}
else if (e.CommandName == "UpdateRow")
{
int rowIndex = ((GridViewRow)((LinkButton)e.CommandSource).NamingContainer).RowIndex;
int CustomerId = Convert.ToInt32(e.CommandArgument);
string Name = ((TextBox)GridView1.Rows[rowIndex].FindControl("TextBox1")).Text;
string Gender = ((DropDownList)GridView1.Rows[rowIndex].FindControl("DropDownList1")).SelectedValue;
string City = ((TextBox)GridView1.Rows[rowIndex].FindControl("TextBox3")).Text;
BAL.bal.UpdateCustomers(CustomerId, Name, Gender, City);
GridView1.EditIndex = -1;
BindGrid();
}
else if (e.CommandName == "InsertRow")
{
string Name = ((TextBox)GridView1.FooterRow.FindControl("txtName")).Text;
string Gender = ((DropDownList)GridView1.FooterRow.FindControl("ddlGender")).SelectedValue;
string City = ((TextBox)GridView1.FooterRow.FindControl("txtCity")).Text;
BAL.bal.InsertCustomers(name, gender, city);
BindGrid();
}
}
6) Correct insertCustomer Method
public static int InsertCustomers(string Name, string Gender, string City)
{
string CS = ConfigurationManager.ConnectionStrings["DBCS"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
string updateQuery = "Insert into tblEmployee (Name, Gender, City)" +
" values (#Name, #Gender, #City)";
SqlCommand cmd = new SqlCommand(updateQuery, con);
SqlParameter paramName = new SqlParameter("#Name", Name);
cmd.Parameters.Add(paramName);
SqlParameter paramGender = new SqlParameter("#Gender", Gender);
cmd.Parameters.Add(paramGender);
SqlParameter paramCity = new SqlParameter("#City", City);
cmd.Parameters.Add(paramCity);
con.Open();
return cmd.ExecuteNonQuery();
}
}
If you want to show a confirmation dialog box, before a row is deleted, include javascript confirm() function, using "OnClientClick" attribute of LinkButton "lbDelete".
<asp:LinkButton ID="lbDelete" CommandArgument='<%# Eval("EmployeeId") %>' CommandName="DeleteRow" ForeColor="#8C4510" runat="server" CausesValidation="false" OnClientClick="return confirm('Are you sure you want to delete this row');">Delete</asp:LinkButton>

how to hide templatefield in gridview

I am repeating this question because i am not able to find answer from anywhere.
I Have a GridView in .aspx page. I want to hide columns based on aspx.cs BindData() method.
I have tried using below code but not able to hide. I am using Asp.net with C#.
Below is my GridView with columns and I have also included the Button click code.
If I select "T-L" which is in below else-if Ladder i am getting this error
DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'tutorial'.
I have marked a test case error in .aspx
For temporary to make my program work i am using 4 gridview to bind 4 query,which is not feasible...How can i hide templatefield invisible based on conditions...
plz help me..

Try having your query still return a result for each column you want to hide even though you won't use those values. In the query for when stype is "T-L", change query from this:
query = "SELECT [id], [st_rollno], [st_name], [theory], [ttotal], [lab], [ltotal] FROM [Attendence_Subject_Wise] WHERE (([branch_name] = #branch_name) AND ([scode] = #scode) AND ([sem_no] = #sem_no) AND ([sess_no] = #sess_no)) ORDER BY [st_rollno]";
To this:
query = "SELECT [id], [st_rollno], [st_name], [theory], [ttotal], [lab], [ltotal], '' as tutorial, '' as tutotal FROM [Attendence_Subject_Wise] WHERE (([branch_name] = #branch_name) AND ([scode] = #scode) AND ([sem_no] = #sem_no) AND ([sess_no] = #sess_no)) ORDER BY [st_rollno]";
EDIT:
To hide the column, add the following method to your code behind:
protected void GridView_DataBound(object sender, GridViewRowEventArgs e)
{
if (stype.Equals("T-L"))
{
MyGridView.Columns[7].Visible = false;
MyGridView.Columns[8].Visible = false;
}
}
And subscribe to the DataBound event on the GridView. Notice that I added an ID to the GridView so I can reference it from the code behind.
<GridView ID="MyGridView" OnDataBound="GridView_DataBound">
