I'm retrieving data from database into the grid for 5 column, there is another 3 columns beside that which I want to fill in using textbox input (using different button).
How to fetch the input from the textbox into the grid after I retrieve the data from database?
Here is the front looks like:
Here is the coding:
<form id="form1" runat="server">
<div>
<asp:Label ID="Label1" runat="server" Text="BNE No: "></asp:Label>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<br />
<asp:Label ID="Label2" runat="server" Text="BNE No: "></asp:Label>
<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Search From Database" />
<br />
<asp:Label ID="Label3" runat="server" Text="Label"></asp:Label>
<br />
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox4" runat="server"></asp:TextBox>
<asp:TextBox ID="TextBox5" runat="server"></asp:TextBox>
<asp:Button ID="Button3" runat="server" Text="Insert to Grid" OnClick="Button3_Click" />
<br />
<%--<asp:Table ID="Table1" runat="server">
</asp:Table>--%>
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField HeaderText="BNE No">
<ItemTemplate>
<asp:Label ID="Label4" runat="server" Text='<%#Bind("BNENo") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="ECN No">
<ItemTemplate>
<asp:Label ID="Label5" runat="server" Text='<%#Bind("KVNo") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Rec Date">
<ItemTemplate>
<asp:Label ID="Label6" runat="server" Text='<%#Bind("ReceivedDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Issued Date">
<ItemTemplate>
<asp:Label ID="Label7" runat="server" Text='<%#Bind("IssuedDate") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:Label ID="Label8" runat="server" Text='<%#Bind("Status") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Location">
<ItemTemplate>
<asp:Label ID="Label9" runat="server" Text=''></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Time">
<ItemTemplate>
<asp:Label ID="Label10" runat="server" Text=''></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Date">
<ItemTemplate>
<asp:Label ID="Label11" runat="server" Text=''></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</div>
</form>
Here is the behind code where I use to retrieve the data by using button 1
protected void Button1_Click(object sender, EventArgs e)//this Button use To call multiple data from database named tblBNE into GridView
{
count = 0;
con.Open();
OleDbCommand cmd = con.CreateCommand();
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT [BNENo],[KVNo],[ReceivedDate],[IssuedDate],[Status] FROM [tblBNE] where BNENo='" + TextBox1.Text + "' or BNENo='" + TextBox2.Text + "' ";
cmd.ExecuteNonQuery();
OleDbDataAdapter da = new OleDbDataAdapter(cmd);
da.Fill(dt);
count = Convert.ToInt32(dt.Rows.Count.ToString());
GridView1.DataSource = dt;
GridView1.DataBind();
con.Close();
if (count == 0)
{
Label3.Text = "record not found";
}
}
So, I want to use button 3 = insert to grid to fill into label9 to 11 using textbox3 to 5. How can I do that?
Thank you in advance :)

}
I am getting empty value when I debugging this code.I think my code is correct but how i am not getting value of textboxes, i don't understand. Please help me for solving my issue.
Thanks in advance.
You probably did not wrap the DataBind() of the Gridview inside an IspostBack check. If you do not then the values will be rested by the DataBind instead of being saved with ViewState.
protected void Page_Load(object sender, EventArgs e)
{
//not here
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
if (IsPostBack == false)
{
//but inside an ispostback check
TrackerGrid.DataSource = source;
TrackerGrid.DataBind();
}
}

In code behind I have:
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if(e.Row.RowType == DataControlRowType.DataRow)
{
string purchaseRequisitionID = gvRequisitions.DataKeys[e.Row.RowIndex].Value.ToString();
GridView gvItems = (GridView)e.Row.FindControl("gvItems");
// new code to send reference to gvItems_RowDataBound
gvItems.RowDataBound += new GridViewRowEventHandler(gvItems_RowDataBound);
int id = Convert.ToInt32(purchaseRequisitionID);
using (SqlConnection conn = new SqlConnection(constr))
{
using(SqlCommand comm = new SqlCommand("procItems_CRUD"))
{
comm.Parameters.AddWithValue("#Action", "SELECT");
comm.Parameters.AddWithValue("#ID", id);
using(SqlDataAdapter sda = new SqlDataAdapter())
{
comm.CommandType = CommandType.StoredProcedure;
comm.Connection = conn;
sda.SelectCommand = comm;
using(DataTable dt = new DataTable())
{
sda.Fill(dt);
gvItems.DataSource = dt;
gvItems.DataBind();
}
}
}
}
}
}
And:
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if(ddlMeasure == null)
{
}
}
}
But I cannot see the drop down list as it returns a null value (as I know it is not a DataRow) but how can I see the footer row and the elements in footer row so that I can add another Item to the order/populate DropDownList etc.
Have been trying to sort this for some time and cannot find a working solution so any pointer(s) will be very much appreciated.
You need to use DataControlRowType.Footer.
protected void gvItems_RowDataBound(object sender, GridViewRowEventArgs e)
{
//check if the row is a footer row
if (e.Row.RowType == DataControlRowType.Footer)
{
DropDownList ddlMeasure = e.Row.FindControl("ddlMeasure") as DropDownList;
if (ddlMeasure != null)
{
ddlMeasure.Items.Insert(0, new ListItem("DLL Found!", "-1"));
}
}
}
SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["MyManageConnectionString"].ToString());
string InstituteId = HttpContext.Current.Request.Cookies["InstituteId"].Value;
protected void Page_Load(object sender, EventArgs e)
{
((Label)Master.FindControl("lblPageName")).Text = "Employee List";
((Label)Master.FindControl("lblPageName")).ForeColor = System.Drawing.Color.Black;
((Label)Master.FindControl("lblPageName1")).Text = " Employee List";
if (Request.Cookies["InstituteId"] == null)
{
string OriginalUrl = HttpContext.Current.Request.RawUrl;
string LoginPageUrl = "INlogin.aspx";
HttpContext.Current.Response.Redirect(String.Format("{0}?R={1}", LoginPageUrl, OriginalUrl));
}

{
BindData();

When I click on add button, footer item data will insert into my database but is insert twice. It is in debug mode and jumping around everywhere.
it show "The process or thread has changed since last step."
You are sending the insert command again by calling gvEmpList.DataSource = GetData(cmd); inside btnAdd_Click. Please check it. The cmd object inside btnAdd_Click is an insert command.
Remove following code from btnAdd_Click
gvEmpList.DataSource = GetData(cmd);
gvEmpList.DataBind();
And call following method
BindData();
I am trying to design gridview inside gridview with insert update and delete but in this i cant insert record. Can anyone Help?
Here is database table
1) tbl_SShow(ShowTimeId{P-Auto inc.},TheatreId,MovieId,FromDate,ToDate)
2) tbl_Show(ShowID{P-Auto inc.},ShowTime,Silver,Gold, Platinum,ShowTimeId)
3) tbl_Theatre(TheatreId{P-Auto inc.}, TName, Taddress)
and here is aspx page

Thanks.
I have a regular gridview with insert,edit,update, delete operations as in below image:
Before inserting data to the DB, I am doing the validation on the textboxes if they are filled or empty like this:
if (txtNewID.Text == "")
{
string message = "Please enter ID";
ScriptManager.RegisterClientScriptBlock(Page, this.GetType(), "Alert", "alert('" + message + "')", true);
isValid = false;
}
But after clicking the OK button of the alert message, the values that i added in the required textboxes are getting lost. How to keep the values of the textboxes in gridview?

Whenever PostBack event is called then we can loss the page data.Did you place the grid in updatepanel otherwise place it in grid if you didn't get maintain the values in viewstate.

Bind the validator to the textbox you need to be required before a submit/post is valid using the ControlToValidate property.
Try to find required field validator dynamically on RowDataBoundEvent of Grid View.
TextBox tb=e.Row.FindControl("txtBox") as TextBox;
tb.ValidationGroup=e.RowIndex;
RequiredFieldvalidation rv=e.Row.FindControl("rv") as
RequiredFieldValidator; rv.ControlTovalidate=tb; rv.ErrorMessage;
rv.ErrorMessage="*";
rv.ValidationGroup=e.RowIndex;
