  GridView RowCommand does not fire

  May 02, 2011 03:26 PM|LINK

  I think it's a common problem, saw so many post on it, most of them said check for IsPostback condition in Page_Load and some said to replace image button with link button, I have tried everything but i still cannot get the link button to fire on GirdView Row Command.

  I load the gridview in page load with !IsPostback condition

  My Grid View

   

  <asp:Panel ID="Panel1" runat="server">
      <!-- Grid View 1 -->
      <br />
      <div id = "dvGrid1" style ="padding:10px;">
      <b><asp:Label ID="lblGridView1Heading" runat="server" Text="Centre Details" Visible="False"></asp:Label></b>
      <br />
      
  
          <asp:UpdatePanel ID="UpdatePanel2" runat="server">
          <ContentTemplate>
          
          <asp:GridView ID="GridView1" runat="server"  Width = "100%"
          AutoGenerateColumns = "false" CellPadding="4" AlternatingRowStyle-BackColor = "#EFF3FB"
          HeaderStyle-BackColor = "#507CD1" AllowPaging ="true"
          OnPageIndexChanging = "OnPaging" DataKeyNames = "ID"
          PageSize = "10" OnRowCommand="GridView1_RowCommand" OnRowDataBound="GridView1_RowDataBound" >

      </Triggers>
      </asp:UpdatePanel>
      </div>
      </asp:Panel>
  
     </div>

   

  Code Behind

   

   protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
          {
             
              string cmdid = (string)e.CommandArgument;
              switch (e.CommandName.ToLower())
              {
                  case "camdelete":
                      //db.close();
                      DeleteUserAssociation(cmdid);
                      break;
  
              }
  
          }

  Page Load

   protected void Page_Load(object sender, EventArgs e)
          {
              
  
              if (!Page.IsPostBack)
              {
                  
  
                  int TotalRows = this.BindGrid(1);
                  this.FillJumpToList(TotalRows);
  
                 
              }
          }

  It's not working.

  I have this similar kind GridView on another page and it works but doesn't work on another, Can't figure out why. though on the other page where it works, i load the GridView not in page load but on click of button.

   

  Also came across this article, didn't help though

  Figured out the problem

  There is a textbox on the page with required field validator, and the link button was not getting passed bcoz of this, made causes validation="false"
