How can I get the selected item on the SelectedIndexChanging handler when using two SelectCommands? I can get the select开发者_开发百科ed row through e.SelectedRow but I'm unable to get the selected column.

It's correct to have more than one SelectCommand in a GridView? If not, what's the best way?


You don't select a column in a gridview, you select a row. If you want a particular field of a row to be "selectable" you might consider using a HyperLinkField or a ButtonField and handle the events for that. But to my knowledge, admittedly it's limited, there is no way to be able to know, purely with a GridView and its SelectedRow Property which field in the row was "selected" when the row was selected.


You don't have to use select commands. you can use template fields and add a named command to it then you can check which of them was clicked in the RowCommand event (and u can also get the row index as well) see below.

  <asp:TemplateField ShowHeader="False">
            <ItemTemplate>
                <asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="false" 
                    CommandName="MyCommand" Text="Button" CommandArgument='<%# Container.DataItemIndex %>'></asp:LinkButton>
            </ItemTemplate>
        </asp:TemplateField>

RowCommend Event below

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
            {
                if(e.CommandName.Equals("MyCommand"))
                {
                    int row = Int32.Parse(e.CommandArgument.ToString());


                }


            }
