How do I bind two elements into a single Link Button ASP.NET

Question

I am trying to bind two elements from a list to a Link Button. The following works separately on two link buttons:

<asp:LinkButton ID="LinkButton2" ForeColor="Black" runat="server" Text='<%# Bind("Name") %>'></asp:LinkButton>

<asp:LinkButton ID="LinkButton1" ForeColor="Black" runat="server" Text='<%# Bind("UserID") %>' OnClick="LinkButton1_Click"></asp:LinkButton>

I want to do it so on the Text Attribute it holds both Name and UserID Bind.

For example;

<asp:LinkButton ID="LinkButton1" ForeColor="Black" runat="server" Text='<%# Bind("UserID") % + " " + <%# Bind("Name") %>' OnClick="LinkButton1_Click"></asp:LinkButton>

How Can I achieve this?

It's definitely do-able. For one, it looks like you h ave a syntax issue in your example, where `%` occurs in the middle of the concatenation. If fixing that doesn't resolve the issue you could always concatenate the fields on the backend and then bind a single element on your frontend. — h0r53, Oct 31 '19 at 13:34

You can do this. Bind comma separated values in CommandArgument property of LinkButton:

CommandArgument='<%#Eval("Name") + ";" + Eval("UserID") %>'

then on click:

protected void LinkButton1_Click(object sender, System.EventArgs e)
{
 LinkButton lnkButton = (LinkButton)sender;
 string[] args = lnkButton.CommandArgument.Split(';');

 string name = string.Empty, userId = string.Empty;
 if (args.Length == 2)
 {
   name = args[0];
   userId = args[1];
 }
}
