Dynamically / Programmatically created Grid and Filters Issue

Hi,
I have a grid that I am creating programmactically. Everything in the grid works fine. In the Column created Event I am setting the
Column.AutoPostback property to true. When I try to fiter on any of the columns I am getting this error

Microsoft JScript runtime error: 'value' is null or not an object

This is happening on all the column filters. Can someone tell me what is causing this since this is making the filtering useless for the grid? Please let me know since this is kind of a vague error from ajax and im having a hard time trying to find the cause and solution around it, your helps appreciated!!

The code is as below.

CheckBoxes="True"

MultipleSelect="True"

DataFieldID="CategoryId"

DataValueField="Category"

OnNodeDataBound="CategoryTree_OnNodeDataBound"

OnContextMenuItemClick="CategoryTree_ContextMenuItemClick"

OnClientContextMenuShowing="onClientContextMenuShowing"

OnClientContextMenuItemClicking="onClientContextMenuItemClicking"

TriStateCheckBoxes="False"
AllowNodeEditing="True">

<telerik:RadTreeViewContextMenu ID="MyContextMenu" runat="server" Skin="Windows7" >

<Items>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/add.gif" Text="Add new category" Value="New">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/edit.gif" Text="Edit category" Value="Edit">

</telerik:RadMenuItem>

<telerik:RadMenuItem runat="server" ImageUrl="~/Images/delete.gif" Text="Delete category" Value="Delete">

</telerik:RadMenuItem>

</Items>

</telerik:RadTreeViewContextMenu>

<telerik:RadTreeNodeBinding Expanded="True" ContextMenuID="MyContextMenu"/>

</DataBindings>

</telerik:RadTreeView>

protected void CategoryTree_ContextMenuItemClick(object sender, RadTreeViewContextMenuEventArgs e)

{

if (e.Node != null)

{

        //check for menuitem text
    }
    else
    {
        return;
    }
}

e.Node is always null, Could someone please advise me why am I getting e.Node as null everytime inside the ContextMenuItemClick event.

[Solved] Achieving a Darker Background for Modal RadWindows

I've read everything I could find about altering the darkness of the "filter" that is applied behind a modal RadWindow. I've tried several things based on that research but with no success. Simply put, what I'm getting is shown in the first attachment but what I'd like to achieve is illustrated in the 2nd attachment (the one wrt 'thickbox').

Here's the CSS styles I've been using:

.modalBackgroundRadWindow {
filter:Alpha(Opacity=95);          /* IE7 and under */
-ms-filter: "Alpha(Opacity=95)";   /* IE8 */
   -moz-opacity: 0.95;
   opacity: 0.95;
}

.modalBackgroundThickBox {
   background-color:#000;
   filter:alpha(opacity=75);
   -moz-opacity: 0.75;
   opacity: 0.75;
}

What do I need to do with the RadWindow to achieve a darker background filter?

Reading formatted grid bound columns

I have gridbound column Col_A and COL_B and dataformat set to currency.Both these columns are integer . I have embeded udpate statement in sqldatasource to update both these columns. Based on business rule I open only one column for editing before update.

If COL B is open for update(COL A is read only in this scenario), When I execute update statement COL A is reading the formatted value and passing to SQL staement i.e formatted currency value and this gives database error because COL A is integer type.
1) How can i get the just the value of COL A (not the formmated one for example , I need 3000 not 3,000). Extravalues in edit mode not working
2) How do i put mask for editable column ,i.e the user can type 5,000 rather than 5000 , but the value read is 5000

Thanks

Filters dont persist on page change?

So i drop down the filter boxes and initiate a filter for Starts With B. I get 25 Results (set to 10 per page). If I go to page 2 then back to page 1 the filter is no longer applied.

What is the recommended way to have filter settings persist across page changes?

Thanks,
Michael
