Cell Text Always &nbsp:

I want to display the text of a specific cell in a textbox whenever I select a row from my gridview but whenever i do this "&nbsp" is the only text that I get even though the cell is not empty. Data on the gridview is bound from my database and I made a function where all the data from my database will be bound on my gridview. Below is the code that I'm using.
textbox1.Text = myGridView.SelectedRow.Cells[3].Text;

Function that binds Data
private void PopulateData()
{
DataTable dataTable = new DataTable();
using (SqlConnection connection = new SqlConnection(WebConfigurationManager.ConnectionStrings["TestCS"].ConnectionString))
{
string path = "PopulateSQL.txt";
StringBuilder sb = new StringBuilder();
using (StreamReader sr = new StreamReader(path))
{
while (sr.Peek() >= 0)
{
sb.Append(sr.ReadLine());
}
string sql = sb.ToString();
using (SqlCommand cmd = new SqlCommand(sql, connection))
{
using (SqlDataAdapter dataAdapt = new SqlDataAdapter(cmd))
{
dataAdapt.Fill(dataTable);
ViewState["NormalGrid"] = dataTable;
}
}
}
}
if (dataTable.Rows.Count > 0)
{
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
}
else
{
//Displays 'No Data Found' to gridview if there are no data in table
dataTable.Rows.Add(dataTable.NewRow());
TraineeGrid.DataSource = dataTable;
TraineeGrid.DataBind();
TraineeGrid.Rows[0].Cells.Clear();
TraineeGrid.Rows[0].Cells.Add(new TableCell());
TraineeGrid.Rows[0].Cells[0].ColumnSpan = dataTable.Columns.Count;
TraineeGrid.Rows[0].Cells[0].Text = "No Data Found";
TraineeGrid.Rows[0].Cells[0].HorizontalAlign = HorizontalAlign.Center;
}
}

You can use this: textbox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
In OnSelectedIndexChanged :
protected void OnSelectedIndexChanged1(object sender, EventArgs e)
{
//Get the selected row
GridViewRow row = GridView1.SelectedRow;
if (row != null)
{
// With
// TextBox1.Text = (row.FindControl("lblLocalTime") as Label).Text;
// Without
TextBox1.Text = Server.HtmlDecode(row.Cells[1].Text.Trim());
}
}
Complete Markup:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false"
OnSelectedIndexChanged="OnSelectedIndexChanged1" AutoGenerateSelectButton="true">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" ItemStyle-Width="150" />
<asp:BoundField DataField="City" HeaderText="City" ItemStyle-Width="150" />
</Columns>

I've already found a solution. The problem is Im using TemplateField instead of BoundField that's why I cant use .Cells[] to get the specific cell that I wanted to get. However, if you are using TemplateField you can use .FindControl() and put in the ID of the label where your binding of data happens (ex. Text ='<%# Eval("FirstName") %>'). You can see that I put label on ItemTemplate to call it's ID.

Using Dropdown List for options for Search function in ASP.NET

I did work on a Search function where the user can type the item they want to search on a textbox, then hit a button to search.
the Search function is already working but for one option only (ContractNo), now I like to add a Dropdown list to add more options for the users to search (add: EmpID, TrainingCode etc)
here is the code for the aspx: (yes i only just included the codes that I think is necessary)
<div id="contentarea">
<p> Search Employee ID, Training Code, Contract Number<br/>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem>Contract Number</asp:ListItem>
<asp:ListItem>Training Code</asp:ListItem>
<asp:ListItem>Employee ID</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="searchText" runat="server" Height="16px" Width="146px"></asp:TextBox>
<asp:Button ID="ButtonSearch" runat="server" Text="Search" OnClick="ButtonSearch_Click" />
<asp:Button ID="ButtonClear" runat="server" Text="Clear" OnClick="ButtonClear_Click" />
</p>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="TrainingCode" DataSourceID="SqlDataSource1" EmptyDataText="There are no data records to display." ForeColor="#333333" GridLines="None">
<AlternatingRowStyle BackColor="White" ForeColor="#284775" />
<Columns>
</a>
</Itemtemplate>
</asp:TemplateField>--%>
<asp:TemplateField HeaderText="ContractNo" SortExpression="ContractNo">
<ItemTemplate>
<asp:Label ID="LabelContractNo" Text='<% #HighlightText(Eval("ContractNo").ToString()) %>' runat="server"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="TrainingCode" SortExpression="TrainingCode">
<ItemTemplate>
<asp:Label ID="LabelTrainingCode" runat="server" Text='<%# Eval("TrainingCode") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="EmpID" SortExpression="EmpID">
<ItemTemplate>
<asp:Label ID="LabelEmpID" runat="server" Text='<%# Eval("EmpID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ContractDate" SortExpression="ContractDate">

<asp:Label ID="LabelContractDate" runat="server" Text='<%# Eval("ContractDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ContractDuration" SortExpression="ContractDuration">

<asp:TemplateField HeaderText="Served" SortExpression="Served">
<ItemTemplate>
<asp:Label ID="LabelServed" runat="server" Text='<%# Bind("Served") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:dbx %>" DeleteCommand="DELETE FROM [SCHOLARSHIPCONTRACT] WHERE [TrainingCode] = #TrainingCode" InsertCommand="INSERT INTO [SCHOLARSHIPCONTRACT] ([ContractNo], [TrainingCode], [EmpID], [ContractDate], [ContractDuration], [ServiceStart], [ContractValue], [Served]) VALUES (#ContractNo, #TrainingCode, #EmpID, #ContractDate, #ContractDuration, #ServiceStart, #ContractValue, #Served)" SelectCommand="SELECT * FROM [SCHOLARSHIPCONTRACT]" UpdateCommand="UPDATE [SCHOLARSHIPCONTRACT] SET [ContractNo] = #ContractNo, [EmpID] = #EmpID, [ContractDate] = #ContractDate, [ContractDuration] = #ContractDuration, [ServiceStart] = #ServiceStart, [ContractValue] = #ContractValue, [Served] = #Served WHERE [TrainingCode] = #TrainingCode" FilterExpression="ContractNo '%{0}%'">
<FilterParameters>
<asp:ControlParameter Name="ContractNo" ControlID="searchText" PropertyName="Text"/>
</FilterParameters>
</asp:SqlDataSource>
and the FULL C# backend code:
private string SearchString = "";
protected void Page_Load(object sender, EventArgs e)
{
}
public string HighlightText(string InputText)
{
string Search_str = searchText.Text;
Regex RegExp = new Regex(Search_str.Replace(" ", "|").Trim(), RegexOptions.IgnoreCase);
return RegExp.Replace(InputText, new MatchEvaluator(ReplaceKeywords));
}
public string ReplaceKeywords(Match m) //this is just to highlight the item searched
{
return ("<span class=highlight>" + m.Value + "</span>");
}
protected void ButtonSearch_Click(object sender, EventArgs e)
{
SearchString = searchText.Text;
}
protected void ButtonClear_Click(object sender, EventArgs e)
{
searchText.Text = "";
SearchString = "";
GridView1.DataBind();
}
Now im thinking to add an if statement maybe? on the FilterParameters? like
<% if (DropDownList1.text == "EmpID"){}
but Im not sure.. Can you suggest other methods please?? Let me know if you might need other codes from the program. Thank you in advance

Try to use generic options. Use DropDown to list all types (EmpID, TrainingCode). On the basis of type selection use Switch to filter by entered text in TextBox.
SearchString = searchText.Text;
Switch(types)
{
case EmpID:
DoOperation();
break;
case TrainingCode:
DoOperation();
break;
}

Ok , here the solution, it's working ok in my computer, I hope this is what you want to achieve. I put some comments in the code, read them
in aspx page , put this code
<div id="contentarea">
<p> Search Employee ID, Training Code, Contract Number<br/>
<asp:DropDownList ID="DropDownList1" runat="server">
<asp:ListItem Value="ContractNo">Contract Number</asp:ListItem>
<asp:ListItem Value="TrainingCode">Training Code</asp:ListItem>
<asp:ListItem Value="EmpID">Employee ID</asp:ListItem>
</asp:DropDownList>
<asp:TextBox ID="searchText" runat="server" Height="16px" Width="146px"></asp:TextBox>
<asp:Button ID="ButtonSearch" runat="server" Text="Search" OnClick="ButtonSearch_Click" />
<asp:Button ID="ButtonClear" runat="server" Text="Clear" OnClick="ButtonClear_Click" />
</p>
<asp:GridView ID="GridView1" runat="server"></asp:GridView>
</div>
and this is the C# code in aspx.cs
private string SearchString = "";
protected void Page_Load(object sender, EventArgs e)
{
}
public string HighlightText(string InputText)
{
string Search_str = searchText.Text;
Regex RegExp = new Regex(Search_str.Replace(" ", "|").Trim(), RegexOptions.IgnoreCase);
return RegExp.Replace(InputText, new MatchEvaluator(ReplaceKeywords));
}
public string ReplaceKeywords(Match m) //this is just to highlight the item searched
{
return ("<span class=highlight>" + m.Value + "</span>");
}
private DataTable GetData(string query)
{
// Read connection string from web.config file , Important, change the
//ConnectionStrings name here (testConnectionString)
// and replace it with your connection name , you can find it in web.config file
// in <connectionStrings> tag , you find it after this tag <add name="
string CS = ConfigurationManager.ConnectionStrings["testConnectionString"].ConnectionString;
using (SqlConnection con = new SqlConnection(CS))
{
SqlDataAdapter sda = new SqlDataAdapter(query, con);
using (DataTable dt = new DataTable())
{
con.Open();
sda.Fill(dt);
return dt;
}
}
}
protected void ButtonSearch_Click(object sender, EventArgs e)
{
SearchString = searchText.Text;
string columnName = DropDownList1.SelectedValue;
string searchSQL = "SELECT * FROM [SCHOLARSHIPCONTRACT] WHERE " + columnName + "= '" + SearchString + "'";
//bind the SCHOLARSHIPCONTRACT table data into GridView1
DataTable dt = this.GetData(searchSQL);
GridView1.DataSource = dt;
GridView1.DataBind();
}
protected void ButtonClear_Click(object sender, EventArgs e)
{
searchText.Text = "";
SearchString = "";
GridView1.DataBind();
}

gvbind();
}
i don't have the product image inside a edit template and also, product image is not included in my code behind. cant understand why a text box becomes visible on product image when i click on update function. please help.

If (e.Row.RowState And DataControlRowState.Edit) > 0 Then
for example
Protected Sub GridView1_RowDataBound(sender As Object, e As GridViewRowEventArgs)
Handles GridView1.RowDataBound
If e.Row.RowState = DataControlRowState.Edit Then
ctype(e.Row.Cells(1).Controls(0),TextBox).Enabled=False

How to Store SelectedRow.Cell[0] value in a session when CommandField is "Select" in a GridView

How to Store SelectedRow.Cell[0] value in a session when CommandField is "Select" in a GridView. ? What the changes i will do in my code so that when a Select Command executes on my grid (By Clicking on Select Link of my grid), It will Store the NatureOfWorkID of that row in the session variable. Below is my code. Please guide me that what changes required in the below code so that when ever some one will click on Select, the natureofworkID of that row will be stored in a Session and i will bind another grid from the session variable as per my requirement.

Your code editted :
(e.CommandName.Equals("Select"))
{
Label lblNautureOfWorkID = (Label)GVNatureOFWork.SelectedRow.FindControl("lblNautureOfWorkID");
if(lblNautureOfWorkID != null)
{
string natureofworkID = lblNautureOfWorkID.Text.ToString();
}
}

protected void GVNatureOFWork_SelectedIndexChanged(object sender, EventArgs e)
{
int index = GVNatureOFWork.SelectedIndex;
string natureofwrkid = GVNatureOFWork.DataKeys[index].Value.ToString();
Session["NOWID"] = natureofwrkid;
lblDisplayNOWID.Text = natureofwrkid;
BindRegionProjectInfoGrid();
}
By adding these lines, Now i am able to get Cell[0] value of the selected row in my grid. Thanks To every one for guiding me to get the solution.

Trying to Add Insert Row to Footer in GridView ASP.net

I'm trying to give the user the ability to create a new record from the footer row and my event handler doesn't seem to be working... or maybe I'm going at this all wrong.
The insert button that I enabled in the gridview doesn't work either...checkout the site at http://aisched.engr.oregonstate.edu/admin/courses.aspx
Here is my code in front and behind:
public partial class admin_courses : System.Web.UI.Page
{
public Table table;
ListDictionary listValues = new ListDictionary();
TextBox textBox1 = new TextBox(); //Name
TextBox textBox2 = new TextBox(); //CR
TextBox textBox3 = new TextBox(); //CourseNum
TextBox textBox4 = new TextBox(); //Dept
protected void Page_Init()
{
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType != DataControlRowType.Footer) return; //Escape if not footer
textBox1.ID = "name";
textBox1.Width = 250;
textBox2.ID = "credit_hours";
textBox2.Width = 25;
textBox3.ID = "dept";
textBox3.Width = 30;
textBox4.ID = "class";
textBox4.Width = 25;
LinkButton add = new LinkButton();
add.ID = "add";
add.Text = "Add course";
add.CommandName = "add";
add.Click += new EventHandler(add_Click);
e.Row.Cells[1].Controls.Add(textBox1);
e.Row.Cells[2].Controls.Add(textBox2);
e.Row.Cells[3].Controls.Add(textBox3);
e.Row.Cells[4].Controls.Add(textBox4);
e.Row.Cells[5].Controls.Add(add);
}
public void add_Click(object sender, EventArgs e)
{
Response.Write("you Clicked Add Course!");
if (textBox1.Text != null && textBox2.Text != null && textBox3.Text != null && textBox4.Text != null) {
listValues.Add("name", textBox1.Text);
listValues.Add("credit_hours", textBox2.Text);
listValues.Add("dept", textBox4.Text); //For Visual
listValues.Add("class", textBox3.Text);
}
LinqDataSource1.Insert(listValues);
Response.Redirect("~/admin/courses.aspx");
}
}

I couldn't make it work without writing code manually to do the Insert. Handling the AddLinkButton_Click event in the Page_Load event by examining the EventTarget hidden field to see if it ends with 'addlinkbutton' feels quite wrong, but it works.
