gridview with multiple buttons

[un33k]

hi i have a big problem which im sure will be simple to some people. ok i have a gridview with a hyperlink and two buttons in 3 different columns. im generating values for these gridview fields and i need to know if multiple buttons are used in a GridView control how can i determine which button was clicked.
this code below
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
}
this calls the same function when i click on any button and i don't want this because i have 2 other buttons which i want to use for other functions. how can i refer to each button.
any sample code would be much appreciated.

You can get that information from sender.
Something like this:
Button btn = (Button)sender;
if (btn.Name=="B1")
// Do this
elseif(btn.Name=="B2")
// Do this ... an so on
else
// Else part

Try it out...This may help you.

Sharing the best from my side...

set the commandname and commandargument properties for each button within the grid. define the gridviewrowcommand event.

<asp:GridView onGridViewRowCommand="FireCommand">
   <Columns>
      <TemplateColumn>
          <asp:Button commandname="Foo" CommandArugment='<%Eval("This")#%>' />
          <asp:Button commandname="Bar" CommandArugment='<%Eval("That")#%>' />
      </TemplateColumn>
   </Columns>
</asp:GridView>

protected void FireCommand(object sender, GridViewRowCommandEventArgs e)
{
     switch (e.CommandName)
     {
          case "Foo":
             int i = (int)e.CommandArgument;
             DoSomethingWith(i);
            break;
          case "Bar":
             DateTime date = (DateTime)e.CommandArgument;
             DoSomethingelseWith(date);
            break;
     }
}
