Passing multiple argument through CommandArgument of Button in Asp.net

Question

I have a gridview with multiple rows, each has a Update button and I need to pass 2 values when someone clicks on Update button. Aside from packing the arguments inside CommandArgument separated by commas (archaic and not elegant), how would I pass more than one argument?

<asp:LinkButton ID="UpdateButton" runat="server" CommandName="UpdateRow" CommandArgument="arg_value" Text="Update and Insert" OnCommand="CommandButton_Click" ></asp:LinkButton> 

As a note, the values can't be retrieved from any controls on the page, so I am presently not seeking any design solutions.

Answer 1

You can pass semicolon separated values as command argument and then split the string and use it.

<asp:TemplateField ShowHeader="false">     <ItemTemplate>        <asp:LinkButton ID="lnkCustomize" Text="Customize"  CommandName="Customize"  CommandArgument='<%#Eval("IdTemplate") + ";" +Eval("EntityId")%>'  runat="server">         </asp:LinkButton>        </ItemTemplate>    </asp:TemplateField> 

at server side

protected void gridview_RowCommand(object sender, GridViewCommandEventArgs e) {       string[] arg = new string[2];       arg = e.CommandArgument.ToString().Split(';');       Session["IdTemplate"] = arg[0];       Session["IdEntity"] = arg[1];       Response.Redirect("Samplepage.aspx"); } 

Hope it helps!!!!

After poking around it looks like Kelsey is correct.

Just use a comma or something and split it when you want to consume it.
