Is it possible to float a DocumentWindow?

For example, in the Visual Studio IDE example of the demos, can the windows Form1.cs or Form1.Designer.cs be floated?

If so, how?

If not, is there a reason? The actual Visual Studio IDE has the ability to float those windows, and I would like to do the same with WinForms.

Thanks.

Chanaging the color of a cell using CellElement

i have download the trial version of your product (WinForms) to test it and give feed back to my boss to decide if this will be useful to buy,
every this is alright except one issue,
pleas have a look on my code

dataGridView1.DataSource = tab; //where tab is returned from the database and have more than 100 row
for (int i = 0; i < dataGridView1.Rows.Count; i++)
     {
            try
                {
                    dataGridView1.Rows[i].Cells[0].CellElement.DrawFill = true;
                    dataGridView1.Rows[i].Cells[0].CellElement.BackColor = Color.Red;
                }
                catch
                { }
       }
the loop stop every time on row number 9
it throw exception "Object reference not set to an instance of an object" on CellElement (CellElement is null)
is that because its a trial version?
i don't want to use Cell Formatting Event cuz this will not be helpful for me
thanks

Theming RadListView for WinForms?

I am having a strange problem theming the RadListView control using the Visual Style Builder in Telerik RadControls for WinForms, Q2 2011, SP1. RadListView no longer appears in the Controls structure at all, for any of the themes! Here is the sequence of events that lead to this:

1) I exported all of the built-in themes to *.TSSP files.

2) I then opened the Office2010Silver.tssp package to use as a starting point for my custom theme.

3) I made some modifications to the theme for the RadButton and RadListView elements.

4) I saved it under a new name (say MySilver.tssp).

5) I integrated it into my application to test it.

6) I found some issues with my RadListView theming, made some changes, saved, and tested again.

7) Now I can't see the RadListView element in ANY of the themes, either the built-in ones or my custom theme, even if I exit and re-start Visual Style Builder.

I would appreciate any help that you can offer. Thanks!

Get Active page on RadPageView

Hi,
I am developing an application in which I need to get the active page on a radpageview in order to make different settings for each page. For example when I am in page 0 I would like to block the button maximize from the application, but on the other hand, when I click on page 1 I need to leave the user to maximize the window if he wants this.

Can this be done? If Yes then what is the event that recognize the page changes from radpageview and how do I get the active page name or index?

Thanks

Y-Axis Autoscale

Hi, I have a problem with autoscale on RadChart
I want Y-Axis to autoscale and this works just fine if values in the dataset i'm binding has variations in it's y-values.
But if values in Y-axis is constant, then autoscale does not seem to trigger ?
I have set IsZeroBased=false.

Any Ideas ?
