RadGrid.get_masterTableView(); id Parameter is null

G Afternoon,
I am a newbie to AJAXing RadControls and having a hell of a time.
Just when i think i have finally got my RadGrid bound to a Web Service i get:
Sys.ArgumentNull Parameter id null
The error is thrown when i call
var tableview = $find("<%= rdScreenings.ClientID %>").get_masterTableView();
I get the correct clientid if i call for that alone. as soon as I add get_ to attach a data source i get the error.

Here is the scripts i am running:
<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
<script language="javascript" type="text/javascript" >

    function pageLoad() {
        proxy.GetScreeningsByZipCode44212(updateGrid);
    }
    function updateGrid(results) {
        alert("<%= rdScreenings.ClientID %>");
        var radgrid = $find("<%= rdScreenings.ClientID %>");
        alert('got radgrid');
        var tableview = $find("<%= rdScreenings.ClientID %>").get_masterTableView();

        alert('before datasource');
        tableview.set_dataSource(results);
        tableview.dataBind();
    }
    function refreshData() {

        proxy.GetScreeningsByZipCode44212(updateGrid);
    }
</script>
</telerik:RadScriptBlock>
// snippets of the html & controls
<asp:ScriptManager ID="scriptManager" runat="server">
    <Services>
        <asp:ServiceReference Path="~/proxy.asmx" />
    </Services>
</asp:ScriptManager>

Cannot get RadWindow to open from codebehind

Hi,

I've been trying to get a modal RadWindow to open upon clicking on a button after the code-behind has executed.
I have tried various suggestions posted on this forum, but none seem to work.

I have boiled down my problem page to just the components necessary so you could get a fairly clear look at it.

It's behavior right now is to modally gray the entire screen, but the popup window does not show up anywhere.

If anyone has an idea what I need to change to get it to work, please let me know, I appreciate the help!!

Regards,

[Solved] How do I loop through rows in a EditItemTemplate server side?

I have a grid that has a GridTemplateColumn, with an EditItemTemplate inside. Inside the EditItemTemplate is a RadNumericTextBox. I'm trying to loop through the rows in the grid server side, outside the normal RadGrid events. I have a button that when clicked sends me server side and in that event I need to loop through and grab the values from all the rows.

I have no problem grabbing the DataKeyValue for the row, it's just the value of txtQuantity I am unable to get.

Here is my ASCX:

<telerik:RadGrid ID="RadGrid1" runat="server" AllowPaging="True" DataSourceID="Products"

Skin="Forest" GridLines="None" OnItemDataBound="RadGrid1_ItemDataBound" Width="50%">

<ClientSettings>

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

</ClientSettings>

<MasterTableView ShowFooter="true" AutoGenerateColumns="False"

CurrentResetPageIndexAction="SetPageIndexToFirst" DataKeyNames="ID" DataSourceID="Products"

Dir="LTR" Frame="Border" TableLayout="Auto" EditMode="Batch" BatchEditingSettings-OpenEditingEvent="Click" CommandItemDisplay="None">

<Columns>

<telerik:GridBoundColumn DataField="ID" DataType="System.Int32" ReadOnly="True" UniqueName="ID" />

<telerik:GridBoundColumn DataField="ProductName" ReadOnly="true" HeaderText="Product" UniqueName="ProductName" />

<telerik:GridTemplateColumn DataField="Quantity" UniqueName="Quantity" HeaderText="Quantity" DataType="System.Int32">

<ItemTemplate>

<%# Eval("Quantity")%>

</ItemTemplate>

<EditItemTemplate>

<telerik:RadNumericTextBox ID="txtQuantity" runat="server" Width="40px" DataType="System.Int32"

NumberFormat-DecimalDigits="0" Skin="Forest">

<ClientEvents OnBlur="Blur" OnFocus="Focus" />

</telerik:RadNumericTextBox>

</EditItemTemplate>

<FooterTemplate>

<telerik:RadNumericTextBox ID="TextBox2" runat="server" Width="40px" DataType="System.Int32" NumberFormat-DecimalDigits="0" Skin="Forest" ReadOnly="True">

<ClientEvents OnLoad="Load" />

</telerik:RadNumericTextBox>

</FooterTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<PagerStyle Mode="NextPrevAndNumeric" />

</telerik:RadGrid>

Here is my Server side:

Protected Sub btnProcess_Click(sender As Object, e As EventArgs)

Try

For Each row As GridDataItem In RadGrid1.MasterTableView.Items

Dim key As String = row.GetDataKeyValue("ID")

Dim qty As RadNumericTextBox = DirectCast(row("Quantity").FindControl("txtQuantity"), RadNumericTextBox)

Next

Catch ex As Exception

Response.Write(ex.ToString)

End Try

End Sub
