Gridview Button Functionality

Question

How to connect a button to a function in C #, ASP? Maybe something like:

<TemplateField> <ItemTemplate> <asp:Button ID="btnFunction1" runat="server CommandName="Function1"/> </ItemTemplate> </TemplateField> 

C # Class:

  protected void Function1() { }

It depends on what you want to do ... if you want to process the GridView command, use the OnRowCommand event instead ...

 <asp:GridView ID="grid" runat="server" OnRowCommand="grid_RowCommand"> <Columns> <TemplateField> <ItemTemplate> <asp:Button ID="btnFunction1" runat="server CommandName="Delete"/> </ItemTemplate> </TemplateField> </Columns> </asp:GridView> 

Then the code behind ...

 protected void grid_RowCommand(Object sender, GridViewCommandEventArgs e) { } 

But if you just want to handle the button click event, register the event declaratively with the Click event ...

 <TemplateField> <ItemTemplate> <asp:Button ID="btnFunction1" runat="server OnClick="Function1"/> </ItemTemplate> </TemplateField> 

and configure the event handler method to match the same signature of the Click ... event method

 protected void Function1(object sender, EventArgs args) { }
