GridView SelectedIndexChanged Problem



I have a GridView with a TemplateField where I'm hosting a button. The button has an event hanlder OnClick, so when it is clicked it will execute some code.

The problem I'm having is that when I click the button in a row, the Button event handler is not excecuted right away. Instead, the GridView selectedIndexChanged is fired and then I need to click my button again to fire the button's event handler.

So, is there a way I could know if the button or the row was clicked  in the GridView SelectedIdexChanged event? And why the Button's event handler is not firering right away?


Thank you so much!

That is event  bubbling and you can get more info about that here.

If you have a Template Field like this

<asp:Button ID="button1" runat="server" Text="Submit" CommandName="Select" 
OnClick="btnSubmit_Click" />

when you click  the button, button  OnClick event fires and then SelectedIndexChanged (as command name was set to Select) and finally row  Command Event.

protected void btnSubmit_Click(object sender, EventArgs e)
//Button Click event            
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
//GridView Selected Index Changed event
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
//Get the row clicked
int rowIndex = Convert.ToInt32(e.CommandArgument);
//Row Command
switch (e.CommandName)
case "Something":
case "Select":
case "Delete":

So, make sure that you are using only Row Command event by setting CommandName to something else other than Select. You do not need that button click event also.
