Error "Cannot find a cell bound to column name" when updatecommand is called

HI,
I have the rad grid in which i have the edit item template. The aspx is as follows:

<telerik:RadGrid ID="radgrid1" runat="server"

EnableViewState="true" ShowStatusBar="true" AllowAutomaticUpdates="false"

ShowFooter="True"

OnInsertCommand="radgrid1_InsertCommand" OnUpdateCommand="radgrid1_UpdateCommand"

OnNeedDataSource="radgrid1_NeedDataSource" >

<MasterTableView DataKeyNames="ProductNumber" AutoGenerateColumns="false" EditMode="InPlace"

CommandItemDisplay="TopAndBottom" CommandItemSettings-AddNewRecordText="Add New Purchase Order">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton">

</telerik:GridEditCommandColumn>

<telerik:GridButtonColumn ConfirmText="Delete this product?" ConfirmDialogType="RadWindow"

ConfirmTitle="Delete" ButtonType="ImageButton" CommandName="Delete" ConfirmDialogHeight="100px"

ConfirmDialogWidth="220px">

</telerik:GridButtonColumn>

<telerik:GridTemplateColumn DataField="ProductNumber" HeaderText="Product Number" UniqueName="ProductNumber"

Visible="true">

<InsertItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text="">

</telerik:RadTextBox>

</InsertItemTemplate>

<EditItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("ProductNumber") %>'>

</telerik:RadTextBox>

</EditItemTemplate>

<ItemTemplate>

<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("ProductNumber") %>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

In the update command, i am trying to access the column as below:

GridEditableItem editedItem = e.Item as GridEditableItem;

//Get the primary key value using the DataKeyValue.

string ProductID = editedItem.OwnerTableView.DataKeyValues[editedItem.ItemIndex]["ProductNumber"].ToString();

//Access the textbox from the edit form template and store the values in string variables.

string strProductNumbervalue = (editedItem["RadtxtPrdNumber"].Controls[0] as RadTextBox).Text;

I am getting the error as "Cannot find a cell bound to column name 'RadtxtPrdNumber', when the code hits "string strProductNumbervalue".
How to fix this?
Thanks

for my start Date, I set my month as oct and year 2012. for my end Date, I set my month as dec and year 2013

Base on this 2 RadMonthYearPicker, the month apart should be 14 month

The only code I can find out is RadMonthYearPicker.selectedDate

IE9 and Symantec Intrusion Prevention / Vulnerability Protection

Background: We've recently started receiving complaints from our users about very slow page load times on our web applications using Telerik controls in IE9. After extensive troubleshooting, we determined that the cause of the slow down was Symantec's IE add-on, Intrusion Prevention or Vulnerability Protection (depending on which version of the SEP client you're running). When we disabled the add-on, page load times were instantaneous and when we re-enabled the add-on, page load times shot up to a very unacceptable 12-14 seconds.

I decided to run IE's profiler to determine what exactly was causing this slow down. The load times for every Telerik script was about 10 times slower when the add-on was enabled than when it was disabled.

Workaround Identified: Since this slow down appeared to be directly related to the Telerik scripts, I decided to start toying around with the RadScriptManager's attributes. As it turns out, setting EnableScriptCombine to false has resolved the issue and page load times are now back to instantaneous.

The idea of combining scripts into one to cut down on network traffic is great and I would like to be able to use that feature again someday which is why I am reporting this problem to you. Hopefully, you can identify why the combined scripts aren't playing nice with the Symantec Intrusion Prevention add-on in IE9, but at least there is a workaround for now.

Controls inside Pane are not resizing

hi,

I have created something like below given example

<telerik:Radsplitter ID="RadSplitter1" runat="server" Height ="660px" Width ="100%" >
        <telerik:RadPane ID="LeftPane" runat="server" Scrolling="none">
            <telerik:RadSlidingZone ID="SlidingZone1" runat="server">
                <telerik:RadSlidingPane ID="RadSlidingPane1" Scrolling="Both" DockText="Filters" Title="Filters" runat="server" >
               ................................
               </telerik:RadSlidingPane>
</telerik:RadPane>
        <telerik:RadSplitBar ID="Radsplitbar1" runat="server">
        </telerik:RadSplitBar>
        <telerik:RadPane ID="MiddlePane1" Scrolling="none" runat="server" Width ="100%" Height="100%">
<table id="mainTable" cellpadding="0" cellspacing="0" width="100%" style="height: 100%;width:100%;">
............. MAIN CONTENT (some control)
</tr>
    </table>
            </telerik:RadPane>
            </telerik:Radsplitter>

when i run this, and dock the RadSlidingPane the main content crosses the width and height of the MiddlePane1 as i have given scrolling="none" in MiddlePane1, it looks like the main content is inside the MiddlePane1 and as the scrolling is none i cant even reach to other part of main content,

I would like to see the content in the Middlepane1 to adjust the screen as i dock the RadSlidingPane. 3

Note:on a first hand i felt that should be because of controls inside MiddlePanel1 but as i would do some event changes i would see the main content adjusting with Middlepanel1 and entire screen fits fine, for your note i have given 100% to all the controls width

Dock horizontal automatic sizing

I combined the Dock/Dock Resizing example (http://demos.telerik.com/aspnet-ajax/dock/examples/dockresize/defaultcs.aspx) with the splitters and sliding panes (and styles) from our application. When I open the sliding pane and unpin, I can move the slider bar horizontally. The dock automatically adjusts its width to match. If I resize the dock vertically, then resize the splitter horizontally, the dock width remain fixed. By double-clicking the dock title bar, the dock snaps to the splitter bar width. Is there event handling or attribute that would mimic this behavior(without having to double click the title bar)?

(Note: The RadDockZone MinHeight attribute percentage vs pixel behaves differently in our application than in this example. In some cases the dock will fill the zone and resizing vertically will resize both dock and zone so you can only make the dock smaller but not larger.)
