I'm trying to retreive values entered by users in the textboxes in the footer of the gridview and insert these values into another sql table.My code is as follows :-
protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName.Equals("addnew"))
{
TextBox t1 = (TextBox)GridView2.FooterRow.FindControl("tfrm");
string frm = t1.Text;
TextBox t2 = (TextBox)GridView2.FooterRow.FindControl("tsub");
string sub = t2.Text;
string cmd = "insert into suggestions values('" + frm + "','" + sub + "','c','c')";
con.Open();
SqlCommand com = new SqlCommand(cmd,con);
int a = com.ExecuteNonQuery();
GridView2.DataBind();
con.Close();
}
}
But the strings 'frm' and 'sub' returns null values.

I have one button and gridview.
The button is located at the outside of gridview.
By clicking the button, I want to trigger the RowCommand event in that grid.
Obviously, I know that I can create same function to run it in that button to achieve samething in the RowCommand event.
However, I would like to know that techinically, I can simply trigger the RowCommand event from outside of GridView.

I have a treeview on the left panel and the gridview in the content page. Both the treeview and the gridview bind to the same datasource and have the same functionality. For instance, clicking employer in the treeview and clicking the employer link in the gridview take you to the same page. All I want is when I click the employer link in the gridview, I want the gridview row command event to call the selectednodechanged event of the treeview, so that the treenode for employer has the selected node style and performs the function of hte selectednodechanged. i have tried treeview.nodes[0].select but this does not fire the selectednodechanged event.

I have a GridView with an associated DataKey, which is the item ID. How do I retrieve that value inside the RowCommand event?
This seems to work, but I don't like the cast to LinkButton (what if some other command is firing the event?), and I'm not too confident about the NamingContainer bit.
LinkButton lb = (LinkButton)e.CommandSource;
GridViewRow gvr = (GridViewRow)lb.NamingContainer;
int id = (int)grid.DataKeys[gvr.RowIndex].Value;
I'm aware that I could instead pass that ID as the CommandArgument, but I chose to use DataKey to give me more flexibility.
I'm also aware that it's possible to use a hidden field for the ID, but I consider that a hack that I don't want to use.

I have several Gridviews that display data from the same table. They are separate for visual effect (Different characteristics). If I select on an item from any grid they can all execute the same code (Show Details).I'm using a row command GridViewCommandEventArgs.Is it possible/How can you get the gridview name from the row command so that I can use just one subroutine.
Sub GV_RowCommand(ByVal sender
As
Object, ByVal e
As GridViewCommandEventArgs)
If e.CommandName = "select" Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = ????.Rows(index)

I'm trying to fire the RowCommand event on a DataGrid control. I've previously done that, but not in this precise case.
Actually I'm working on someone else code so I can't really change the structure of his page excepted if it's really necessary.
The code of the page is heavy, so I've summarized the problem in a small project and the page behaves the same way too.
Basically I have a GridView which I bind to a DataSet. According to those data, I sometimes need to add, at the end of a row, a "Details" button (a LinkButton).
By pushing this button, I want to show a second GridView containing those details.
Let's add to this that the columns number of the first GridView is variable, those LinkButton need to be added dynamically.
The first GridView is generated without any problem and when my mouse is over one of the LinkButton, I can see that the link is something like "javascript:__doPostBack('dataGridView$ctl02$lnkDetail','')". When I click on this link and debug step by step : Page_Init, Page_Load, OnPrerender, RowDataBound but no RowCommand, and I don't know why!
In the exemple, I've explicitly set the EnableViewState to true from what I've read here and there, but nothing's changed.

And the code of my .aspx :

It has to do with the RowCommand 'Cancel'. When clicking on my Edit button for a row, the GridView puts the row into edit mode without a problem (I have no code for the Edit command, I let the control do everything).
Once in Edit mode, if I click the Cancel button (again, I have no code handline this RowCommand, I let the control handle it (like i do with many other GridViews)) I get the following exception:
"System.InvalidOperationException: Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."
