Hi,
    I am using a Telerik radgrid for asp.net ajax in a ascx page.I have register a JS function in the page load of the ascx where in i am not able to find the Master TableView of the radgrid in the function .The code in the JS function is as below .
 var radgrid = <%=radGrid1.ClientID%>;
i am not able to get the master table view for the radgrid. i even tried $get("<%=radGrid1.ClientID%>") but in vain.

Can anyone let me know the fix for the above issue.

Thanks,
Avik.

Hello Avik,

Can you try using the following JavaScript code and see if it helps?

ascx:
var grid = $find("<%=RadGrid1.ClientID %>"); 
var MasterTable = grid.MasterTableView; 

Thanks
Princy.

Hi Princy,
    Thanks for your reply.I tried what you said but it is not able to find the control .When i debugged, the control is null.I think since the javascript is being called from the page load the $find syantax is not working.
    When we were using radgrid for asp.net ,in the same JS function we use to get the master table by using the following code 
     var radgrid = <%=radGrid1.ClientID%>;
     radgrid.Iw.MasterTableView used to give us the master table .
I am not able to find the equivalent of the same in radgrid for asp.net ajax.


Thanks,
Avik.

Hello Avik,

Here is the code that should work properly for you:

var grid = $find("<%=RadGrid1.ClientID %>"); 
var MasterTable = grid.get_masterTableView(); 

You may also be interested in reviewing the following topic from the online documenation which is dedicated to speed up the migration process between the Classic and the ASP.NET AJAX version of the grid:

Hi Stephen,
    Thanks for your reply.Before posting this query ,i  had tried what you had suggested, but $find is not working .The JS function in which i am using the syntax is not able to find the radgrid control.

The JS function what i am talking about is registered in the Page Load event of the page and may be because of that $find is not working.

When we were using radgrid for asp.net ,in the same JS function we use to get the master table by using the following code 
     var radgrid = <%=radGrid1.ClientID%>;
     radgrid.Iw.MasterTableView used to give us the master table .
I am not able to find the equivalent of the same in radgrid for asp.net ajax.
I am very much aware of the fact that in radgrid for asp.net ajax we have to use the get_masterTableView(), but it throws an null error when i do the same in the JS function.But for a RowClick JS function get_masterTableView()  works well.

Thanks,
Avik.

Hi All,
Adding some more details to the issue raised by me.In my page if the Request Query String contains the value for productid then a javascript function is registered in the paeg load and that will get fired in the page load itself.The code is as below...


if

(!string.IsNullOrEmpty(productid))
this.Page.RegisterStartupScript("scriptKey", "<script>PopulateonLoad('" + productid + "','" + SourceCode + "');</script>");

The JS function that will be called is as below....
function PopulateonLoad(productid,promotionCode)
{

//debugger

;
var gridload = <%=RadGrid1.ClientID %>;
var gridload1 = $find("<%=RadGrid1.ClientID %>");
//gridload1 is showing as null
var gridload2 = $get("<%=RadGrid1.ClientID %>");
var ProductID = null;
for (i=0;i<gridload.Iw.MasterTableView.Controls[0].Rows.length;i++)
{
var row0 = gridload.Iw.MasterTableView.Controls[0].Rows[i];
if(typeof row0.KeyValues != 'undefined')
{
ProductID = row0.KeyValues[
"ProductID"];
if(ProductID == productid)
{
row0.Selected =
true;//
row0.Expanded = true;//
Populate(ProductID,promotionCode);
}
}
}

}
I want to know the equivalent of the highlighted(red) one in radgrid for asp.net ajax controls because the highlighted one works well in radgrid for asp.net.

Hoping that someone can help me out.

Thanks,
Avik.

I'm having the same problem in an .ascx (no problem in a .aspx).  Did you ever find /get a resolution?

thanks
