Inserting data into a radgrid inside a nestedviewtemplate

I am trying to insert data into a radgrid that is nested inside another radgrid. The problem I am having is getting the ID from the master table. the solution I tried looks like this:

protected void ImagesLDS_Inserting(object sender, LinqDataSourceInsertEventArgs e)
    {
        Image i = (Image)e.NewObject;
        i.ItemID = Convert.ToInt32(ItemGrid.MasterTableView.DataKeyValues[0]["ItemID"]);
    }

I thought this was working, but it seems ItemGrid.MasterTableView.DataKeyValues[0]["ItemID"] is always equal to 1.

Here is the markup for the grids:

    
            <telerik:RadGrid ID="ItemGrid" runat="server" AllowAutomaticDeletes="True" AllowAutomaticInserts="True"

There are other grids and LinqDataSources that have the dame issue. I would like to use the Label1 but I am not sure how to access it.

RadUpload works great - Download not so much

I'm using the RadUpload control for uploading files in my ASP.Net app, and it works great.
For Downloading, the only thing I have to use is the standard ASP.Net control, since no 3rd party controls appear to exist.
With the standard Download control, downloading even a 40 meg file, I get the error message "insufficient system resources exist to complete the requested service".

I've checked the server, and the RAM, hard drive and CPU on the server are all quiet when the request is made. I've made the request from several different computers, both inside and out of the firewall.

I don't understand what's causing this error message or how to fix it?

Has anyone encountered this problem before?

Is it possible to use the RadUpload control to do downloads?

Select Text on Entry after SetFocus

I have several textboxes and comboboxes in an UpdatePanel all with AuotPostBack set. In teh TextChanged sub I do some processing tehn want to conditionally set focus to a comb box. I do this by calling ScriptManager1.SetFocus(cbotype_1.ClientID). When I do this then the text is not selected (highlighted) the same as it would have been by the user tabbing into the control. Any ideas how I can do this with server side code if possible?

DatePicker not formatting DateTime

We might use any culture in our system and we are allowed to override the DateTime formats for it.

for example en-GB usually the shortdate format gives 25/02/2010 but we might override it with MM/dd/yyyy for example which gives 02/25/2010 a US style format.

This seems to work when the DateInput.ReadOnly is set to false but doesn't seem to work when ReadOnly is set to true.

Any ideas?
