Ok, I am still trying to evaluate your product.  I am binding to a business object list.  I don't want automatic generation of columns at runtime because I want the headers named something more reader friendly.

I turn off the checkbox which will auto-generate the columns. 
I then add the three columns to the collection

I see the columns that I generate in the collection editor while looking at design view, but when I run the app I don't see one of the columns I created.  I look at the "Source View" and the column that I can't see when the app runs is not in the source code...but I can still see it in "Design View".

Why is the changes not tranferring into "Source"?  Once I made the changes manually in source, I was able to see the column in runtime.

This also happens with all other settings.  For example "HeaderStyle-Width", "HeaderStyle-Font-Size" etc... Everytime I make a change in the designer it does not transfer into "Source".  I always have to go into "Source" and change it manually.

Was able to get some technical help from a Developer Support Consultant.

He acknowledged the same problem. 

The problem is when my Grid was embedded within a RadSplitter/RadPane.  When I would make changes to my grid in this situation, I would see the changes in "Design View", but the changes would NOT transfer to "Source".  Keep in mind on the "Initial" build of the page everything works fine.  It's only when you try to edit an "Existing" file that the problem starts to occur.

He found a workaround that if you click around the designer a couple of times you will finally get the "Asterisks" to appear on the file tab which shows that visual studio recognizes the change to that particular file.  Once this happens the change is transferred into "Source".

So far this only seems to be an issue when the Grid is embedded within other controls.

More to come....

Hi Michael,

We do not think the problem is related to any of the Telerik controls.
I was able to reproduce the issue by using two ASP.NET controls (as we share a similar designer class) - asp:Panel and asp:GridView.

<asp:Panel ID="Panel1" runat="server" Height="136px">  
        <asp:GridView ID="GridView1" runat="server">  
        </asp:GridView> 
    </asp:Panel>  

If you are using VS 2008 SP1, with .NET 3.5 SP1, try to  modify the Columns collection (using the designer) and the result will be the same. Therefore I assume that this is a general issue with MS Visual Studio 2008.

You are correct.  I have tested your sample code and it is also an issue.

Just did a VS Studio Bug lookup.  Apparently this is a known issue.

Read the community discussion at the bottom. Although Microsoft says its fixed, people are still having problems.  Other 3rd party controls are also mentioned as being affected.
