I am having a problem when trying to get the master table view of a grid in a window.onload function.  It works fine when the form first loads, but failes to find the grid on the postback.

Here's the javascript:

 

 

 

 

 

 

 

 

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">

 

 

 

<script type="text/javascript" >

 


window.onload =

 

function () {

 

 

   var masterTable = $find("<%= radGridCashFlows.ClientID 
%>").get_masterTableView();
   masterTable.selectItem(masterTable.get_dataItems()[0].get_element());

 And here's the grid control:

 

 

 

<telerik:RadGrid ID="radGridCashFlows" runat="server" Width="520px" Height="135px" Skin="Default" AllowMultiRowSelection="false" >

 

 

 

<ClientSettings EnableRowHoverStyle="true" >

 

 

 

<ClientEvents OnRowClick="CFSelected" />

 

 

 

<Selecting AllowRowSelect="True" UseClientSelectColumnOnly="true" />

 

 

 

<Scrolling AllowScroll="true" SaveScrollPosition="true" UseStaticHeaders="true" />

 

 

 

</ClientSettings>

 

 

 

<MasterTableView AutoGenerateColumns="false" Font-Size="Larger" ClientDataKeyNames="CFDesc,CFTypeDesc,CFAcctTypeName,CFID,CFTypeID,ScenTargetID,StartYear,EndYear,YearlyReqment,InflationPct" DataKeyNames="CFDesc,CFTypeDesc,CFAcctTypeName,CFID,CFTypeID,ScenTargetName" NoMasterRecordsText="No Cash Flows Created.." >

 

 

 

<Columns>

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="CFDesc"

 

 

 

HeaderText="Cash Flow Name:"

 

 

 

SortExpression="CFDesc"

 

 

 

UniqueName="CFDesc"

 

 

 

HeaderStyle-Width="140px" />

 

 

 

<telerik:GridBoundColumn

 

 

 

HeaderStyle-Width="150px"

 

 

 

DataField="CFTypeDesc"

 

 

 

HeaderText="CF Type:"

 

 

 

SortExpression="CFTypeDesc"

 

 

 

UniqueName="CFTypeDesc" />

 

 

 

<telerik:GridBoundColumn

 

 

 

HeaderStyle-Width="90px"

 

 

 

DataField="CFAcctTypeName"

 

 

 

HeaderText="Acct. Type:"

 

 

 

SortExpression="CFAcctTypeName"

 

 

 

UniqueName="CFAcctTypeName" />

 

 

 

<telerik:GridBoundColumn

 

 

 

HeaderStyle-Width="120px"

 

 

 

DataField="ScenTargetName"

 

 

 

HeaderText="Solve For:"

 

 

 

SortExpression="ScenTargetName"

 

 

 

UniqueName="ScenTargetName" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="CFID"

 

 

 

HeaderText="CFID:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="CFTypeID"

 

 

 

HeaderText="CFTypeID:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="ScenTargetID"

 

 

 

HeaderText="ScenTargetID:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="StartYear"

 

 

 

HeaderText="StartYear:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="EndYear"

 

 

 

HeaderText="EndYear:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="YearlyReqment"

 

 

 

HeaderText="YearlyReqment:"

 

 

 

Visible="false" />

 

 

 

<telerik:GridBoundColumn

 

 

 

DataField="InflationPct"

 

 

 

HeaderText="InflationPct:"

 

 

 

Visible="false" />

 

 

 

</Columns>

 

 

 

</MasterTableView>

 

 

 

</telerik:RadGrid>

 


I am doing this so that I can fire a javascript function that sets some page characteristics based on the current grid row.  I could do this server-side, but I have the Js function written, and don't want to duplicate the logic.  Any suggestions would be appreciated.

Thanks,
Shahryar

Hello Shahryar,

Since all the ajaxified controls rendered after the window.load event, you can try your code in the reserved client side pageLoad event.

Sample Code:
<script type="text/javascript">
    function pageLoad() {
        var grid= $find("<%= RadGrid1.ClientID %>");
    }
</script>


Hope this information helps,
Princy.
