GridView RowCommand event not firing

Question

I have a GridView that looks something like this:

Answer 1

You must not bind your grid on postbacks in Page_Load, only when something changed that causes the Grid to reload data(f.e. Sorting,Paging) and only in the appropriate event-handlers.

Another possible reason: Have you disabled ViewState somewhere?

Answer 2

Did them all and got nowhere then discovered this: onrowcommand="GridView1_RowCommand" on the GridView1 definition line in html.

Answer 3

Tried the above answers and still could not get a post back. Ended up being a Unique ID issue. I had two <ItemTemplate> with buttons that had the same ids. (In different grid views. My second one was in a User Control)

Changing the <asp:Button ID="" /> to a Unique ID solved the post back issue for me.

Just thought I'd post for any one else who tried the other options with no luck.

Answer 4

You can also check the HttpContext.Current.Request.Form["__EVENTTARGET"] and if it ends with the ID of the control, rebind the GridView and use Page.FindControl with the event target to find the control that fired the event

Answer 5

Put the grid.Databind() inside if (!IsPostBack)

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        grid.DataBind();
    }
}

Answer 6

I just had a colleague who encountered the same problem; his was caused by the onrowcommand= attribute not being set in the asp:GridView element. This should be set to the name of the handler which will be handling the event.

... just in case someone has the same issue!
