JavaScript

function ShowError()
{
alert("There is an error!!");
}

C#

protected void ListView_OnItemCommand(object sender, ListViewCommandEventArgs e)
  {
    if (String.Equals(e.CommandName, "CommandName"))
    {

      // Your code here for condition check
      Page.ClientScript.RegisterStartupScript(GetType(), "Key", "ShowError();", true); 

    }     

}
