How I use the ItemCommand Event for my ListView in my ASP.NET Application

Question

I have a ASP.NET Application with a ListView. In every Row in my ListView I have a LinkButton that open a new webform "Benutzer.aspx". my Problem is that I don't get the Index of this Row. I use the ItemCommand Event but it not work :(

Here my Code:

ASPX:

...

        <ItemTemplate>

            <tr runat="server"> 

                <td align="left" ><asp:Label ID="Label1" Text='<%# Eval("Benutzer") %>' runat="server" /></td>
                <td align="left"><asp:Label ID="Label2" Text='<%# Eval("eMail") %>' runat="server" /></td>
                <td align="left"><asp:Label ID="Label3" Text='<%# Eval("Vorname") %>' runat="server" /></td>
                <td align="left"><asp:Label ID="Label4" Text='<%# Eval("Nachname") %>' runat="server" /></td>
                <td align="left"><asp:Label ID="Label5" Text='<%# Eval("Telefon") %>' runat="server" /></td>

             <td align="left"><asp:LinkButton runat="server" Text="Anzeigen" CommandName="Anzeigen" OnCommand="ListView1_ItemCommand" CommandArgument="myArguments"></asp:LinkButton></td>

            </tr>

        </ItemTemplate>

...

cs file:

...

protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
        {
            if (e.CommandName == "Anzeigen")
            {
                Label lbText = (Label)e.Item.FindControl("Label2");

               string email = lbText.Text;

               Session["email"] = email;

               Response.Redirect("Benutzer.aspx");

            }
        }

...

What is the matter :(

Try this:

First you need to have the index of the button. So in the html code add this in the CommandArgument of the button to get the index:

CommandArgument='<%# Container.DataItemIndex %>'

Then in the codebehind:

if (e.CommandName == "Anzeigen")
{
      Label lbText = ListView1.Item[e.CommandArgument].FindControl("Label2");
      string email = lbText.Text;           

           Session["email"] = email;           

           Response.Redirect("Benutzer.aspx");           
}
