Hello Niloofar,

You can achieve this by attaching 'onclick' client event to LinkButton 'lbSelect' with row index as parameter. Then in the event handler access the other label controls and pass the value to new page. Following code shows how to access the value from client side.

C#:

protected void grdCustomersInfo_ItemCreated(object sender, GridItemEventArgs e)
    {
     if (e.Item is GridDataItem)
       {
           GridDataItem item = (GridDataItem)e.Item;
           LinkButton btn = (LinkButton)item.FindControl("lbSelect");
           btn.Attributes.Add("onclick","btnclick('"+item.ItemIndex+"');");
       }
    }

Java Script:

<script type="text/javascript">
       function btnclick(index) {
            var masterTable = $find("<%= grdCustomersInfo.ClientID%>").get_masterTableView();
            var row = masterTable.get_dataItems()[index];
            var lblid = row.findElement("CustomerID");
            var value=lblid.innerHTML;
            // access the other Label control also
        }
    </script>

Thanks,
Princy.

Hello niloofar,

You shoud use:

var masterTable = $find("<%= grdCustomersInfo.ClientID%>").get_masterTableView();

For more information see this help article and this site.

Please tell us what is the error that you get when using the code-above.

when i use your code i have this error when page load:
the controls collection cannot be modified because the control contains code blocks(i.e <% ... %>)
please help me
thanks

Hello niloofar,

Try to place all javascript code that contains <% %> tags into RadCodeBlock, and place this inside the form tag, not in the header. For example see the code snippets bellow.

Master Page:

<head runat="server">
  <title></title>
  <asp:ContentPlaceHolder ID="head" runat="server">
  </asp:ContentPlaceHolder>
</head>
<body>
  <form id="form1" runat="server">
  <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
  </telerik:RadScriptManager>
  <div>
    <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server">
    </asp:ContentPlaceHolder>
  </div>
  </form>
</body>
</html>

Content Page:

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="Server">
</asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">
  <telerik:RadCodeBlock runat="server">
    <script type="text/javascript">
      function btnclick(index) {
        var masterTable = $find("<%= radGrid1.ClientID%>").get_masterTableView();
        return false;
      }
    </script>
  </telerik:RadCodeBlock>
  <telerik:RadGrid runat="server" ID="radGrid1" OnNeedDataSource="radGrid1_NeedDataSource">
  </telerik:RadGrid><asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return(btnclick())" />
</asp:Content>

Kind regards,
