Re: GridView RowCommand event not firing!!

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

The reason of wiring the events at runtime is because I am creating a
dynamic form from the database. Controls are created depending on the data
of the database.

Sorry, the code should have been like this: I'm using the constructor not
the pageload event

public myUserControl()
{
SetLinkedTable(GetSource())
}

This constructor is called in the overidden method CreateChildControls() of
another usercontrol
( the form creator usercontrol)

Again i think you are coming up against an order events fire type problem,
you are hooking up your GridView event handlers programatically in the
PageLoad event, how do you know that the PageLoad event fires before the
RowCommand event, if the RowCommand event fires before the PageLoad event
then the event has already happened before you even wire up the event
handler.

Again i can't see any good reason for hooking up your event handlers
programatically from your code, the reason you do that usually is if the
control to which you are hooking up the event handlers has also been
created
programatically. If you are creating the GridView declaritively in the
mark
up then also wire up your event handlers like this.

I've tried it but it still wont fire the event.
Here is the code:

protected void Page_Load(object sender, EventArgs e)
{
SetLinkedTable(GetSource())
}

private void SetLinkedTable(DataTable source)
{
gvLinkedTable = (GridView)skin.FindControl("gvLinkedTable");
AttachEvents();
gvLinkedTable.DataSource = source;
gvLinkedTable.DataBind();
this.Controls.Add(skin);
}

private void AttachEvents()
{
gvLinkedTable.RowCommand +=new
GridViewCommandEventHandler(gvLinkedTable_RowCommand);
gvLinkedTable.RowDataBound += new
GridViewRowEventHandler(gvLinkedTable_RowDataBound);
}

private void gvLinkedTable_RowCommand(object sender,
GridViewCommandEventArgs e)
{
if (e.CommandName == "Delete")
{
int pk = Convert.ToInt32(e.CommandArgument);
DeleteItem(pk);
SetLinkedTable(dt);
}
}

The order that event handlers execute can cause this kind of problem.
Why
are
you setting the command argument of the delete button in the
RowDataBound
event, why not just declare it in the markup? Try that and see if the
RowCommand event fires.

I am using a GridView inside a UserControl which has a template column

RowCommand and RowDataBound event.

I am using the RowDataBound event to set the commandargument of the
delete
button. The event is being fired and works fine.

When I press the delete button, the RowCommand event is not firing!
and
neither is the RowDeleting (the button's commandName is "Delete")
Any idea why?
