RadGrad-how to populate dropdown with selection from another dropdown in editform

I am using a radgrid with the command items of insert and edit turned on. I am using a form template for the edit/insert views. In my form template i have multiple dropdown menus. I am able to populate the first dropdown thru the itemDataBound event with no problem. My question is how would i populate the next dropdown menu with what is selected in the previous drop down menu? The dropdowns i am referring to are in the gridSections (radgrid) in the below markup. The ddlQuestion dropdown is populated with data dependant on what is selected in the ddlSection dropdown. In the selectedIndexChange for ddlSection I would have to access the edit form somehow. I am not sure how to do this. Any ideas?

Iframe crushes rad dock

Hello! I've noticed that any simple iframe makes any Rad Dock unmoveable and frozen at the last version of Rad Controls.
This is the simple code that makes unmoveable dock without a half of the borders at any browser on my system.

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="MasterPortal.WebSite.WebForm1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Could you please give me some advices about how can irame could be placed at Rad Dock without making it unusable?

trap for multi-row selection

I am looking for a way to trap for multi-selection of grid rows.

My issue is that I have a web service return data after a row select/deselect. If I hold the ctrl/shift key and select 4 rows the web service is called 4 times. I saw a post that uses a timer but I am checking to see if anyone has worked a solution to trap for the ctrl/shift key press. I am a little fuzzy on this one but I disabled the drag to select option to eliminate that possibility.

Thanks,
Craig

PageRequestManagerServerErrorException When GroupByExpression button clicked

We have a RadGrid with some custom sorting, master/detail rows and GroupByExpressions. The problem occurs when a groups toggle button is clicked, calling "._toggleGroupsExpand/Collapse", then clicking on a parent grid's sortable column.

I saw the older threads regarding this error that talked about firewalls interfering with the x-microsoft header and that doesn't seem to be the case here. the headers are staying intact and there's no firewall applicable, this is running on localhost.

Grouping automatic sorts result

Hi,

I currently use the latest Version 2010.3.1317.40 of the RadGrid. Is there a change in the behavior, RadGrid handles data when grouping is enabled? The former versions displayed the data as delivered. Now the data will be automatically sorted. But I don't want this. I don't have changed anything in my code. Is it a bug or have I set some property now?

Thanks.

Save dynamically created Raddoc into the database

Hello,
I am trying to save the dynamically created raddoc in to mssql. GetRegisteredDocksState() does not recognize the newly created raddoc.

Public Sub SaveState()

Dim dockState As String

Dim serializer As New Script.Serialization.JavaScriptSerializer()

Dim stateList As List(Of DockState) = RadDockLayout1.GetRegisteredDocksState()

Dim serializedList As New StringBuilder()

Dim i As Integer = 0

While i < stateList.Count

serializedList.Append(serializer.Serialize(stateList(i)))

serializedList.Append("|")

i += 1

End While

dockState = serializedList.ToString()

....

Do you have any KB article on the same ?
