I've attempted several methods of centering the loading panel on my page (has a fairly long RadGrid) and so far whnever I set the (issticky="true") my panel appears to be invisible or isn't being fired.
Actually with this current setup it is invisible on issticky true or false.
Here is my current implementation:

I'm running into an odd whack-a-mole type error. I have the following:
Master Page containing
User control which itself contains a single RadPanelBar (a left nav menu)
Page with Master set to above and:
Main content area has:
5 standard DropDownLists
2 standard TextBoxes
1 standard Button control
1 RadGrid
I have the ASP.NET AJAX Extensions installed and the AJAX Control Toolkit installed. I'm using 2007.2.1107 of the Prometheus controls.
The problem occurs when I put a Prometheus RadWindowManager in the user control referenced in the left content area on the master page. In all cases, the problem only occurs on a postback. Initial load of the page in all cases works fine. I'm using Firebug to track down the error however I also get it in IE7.
With no asp:ScriptManager located anywhere, I obviously get the yellow screen of death and something to the effect that the ScriptManager is missing.
If I put the asp:ScriptManager in the Master page, initial load works fine, however clicking the button (i.e. firing a postback) gives me a "Telerik is not defined" javascript error.
If I put the asp:ScriptManager in the user control, I get a "Sys is not defined" error.
If I put the asp:ScriptManager in content area on the Page in question, I get "Telerik is not defined".
My preference obviously would be to put the ScriptManager on the master page.

Ok, so I'll start off with what I'm having issues with and then paste code below.
I have a RadGrid that allows for grouping and sorting. I have the RadGrid tied to a DataSet that is stored in ViewState.
I need to manually add columns in the code behind so that I can allow some to be hidden and also becasue we allow the users to add extra columns from the database.
After a lot of playing I thought I had it working, but now my problem is that when sorting the column headers go away.
The issue is, and I have no idea why it's designed this way, but on every single post back, the Column collection in the RadGrid keeps the column count and the number of columns there, but it clears all the properties on that column so that there is no header text, there is no DatatField property, there is DataType.
I just need to know why this does this and how I can get around it, it's been like 2 full days of frustration and trying to get those columns to be persistant across post backs.
RadGrid in aspx:
A lot of different RadGrid code in the codebehind:
Ok, so in explaination of what's going on in the code behind.
1. The dataSource DataSet is filled when you click on a treeNode.
2. The "JobRecordNumber" is added to the RadGrid Columns
3. When a user clicks the btnStock it goes out and adds a new column to dataSource and fills it with the different stocks.
4. Then it adds that column to the RadGrid.
This is my code, I'm just really wondering where I'm going wrong to make the columns in the RadGrid clear their properties on post back and also, if that's just how it is, how can I fix my code to work for me.
Thanks
Davey

I am using the following RadAjaxManager code to control a RadDatePicker and a RadGrid. I want the grid to update when either of those controls fires. Changing the date in the date picker will load a new set of data in the grid.
It technically works, I guess, but not as well as I would expect when changing the date on the calendar. When events fire on the grid, I can see the LoadingPanel during the duration of the update until the changes are processed.
When changing the date on the date picker, the loading panel only flashes on the grid and immediately disappears. The update still takes another moment to occur. (On the same note, the status bar of the grid also returns to "Ready" immediately even though the update is not complete.)
Is there something I have wrong in this declaration to cause this to happen?
Thanks,
Joel

I am getting the above when trying to cast a datarow returned in a nodedatabound events' radtreenodeeventargs to a strongly typed datarow derived from the strongly typed datatable that the treeview was originally bound to.
To reproduce, just create a strongly typed dataset with one table, add a prometheus treeview to a page with an object datasource bound to the control that derives from the table you added to the dataset, then hook up the nodedatabound event for the control.
If you then create a datarow and try to cast it back to your strongly typed object it fails.
eg
protected void RadTreeView1_NodeDataBound(object sender, RadTreeNodeEventArgs e)
{
DataRow datarow = ((DataRowView)e.Node.DataItem).Row;
MyDataset.MyDataRow myrow = (MyDataset.MyDataRow)datarow;
Can someone please help me with this.

I have some preliminary questions for using Scheduler.
1. I do not want to keep the ViewState for the Scheduler. So, in Page_PreRender I bind the Scheduler with appointments ( a custom class object list) everytime. I only set the RadScheduler1.DataSource and then call RadScheduler1.Rebind(). -- is this okay?
2. When the page loads first time it displays the results correctly (calls AppointmentCreated event too). But then when I change the date, it again fetches appointment for next date - there are appts for that date too - but then AppointmentCreated does not get called and the Scheduler is displayed empty. How can I make sure that Scheduler gets refreshed on every Page_PreRender or any other event like that.
3. The other thing is - I use RadTooltip in Scheduler. When OnAjax_Update() gets called, the .net calls PreRender again and it again binds the RadScheduler. I understand that I can't avoid it - so other approach would be to update RadScheduler in different events but not in PagePreRender. If I do that, then since I am not using ViewState, and call is made for Tooltip - will there be any problem? Or do you suggest any alternative for Tooltip - like calling PageMethods through Ajax to get the content to display in tooltip control and not go through whole page event cycle.
