RowDeleting e.cancel cause crash

Hi,

The problem appear in the Option dialog of the radRibbon. In this dialog I got a radGridview, if something are deleted, I check if I can delete it. If not a set the e.cancel = true. If e.cancel=true the system give me this error:

Desert?

Ok, so I have the trial for the Q1 2008 Winforms and I would like to test out the desert theme...actually...any theme would be nice.

I create a new radform, set the theme to Desert and in the designer it looks great. I run it...everything goes back to plain.

If I choose other themes most of them don't even change from the default. The few that do still don't show anything at runtime.

What am I missing?

Looping through Selected Rows

I'm in the process of resolving the issues created by upgrading to Q1 2008 for all of my instances of the RadGridView control. In Q3 2007, I was able to loop through the selected rows and add the value of a specific cell to a generic list by doing the following:

Dim mPartNumberList As New List(Of String)
Dim selectedRows As List(Of GridViewRowInfo) = PartListRadGridView.SelectedRows

For Each row As GridViewRowInfo In selectedRows
mPartNumberList.Add(Convert.ToInt32(row.Cells(1).Value))
Next

This now fails. What is the equivalent in Q1 2008?

Thanks.

Progress bar missing PerformStep?

I've added RadProgressBar to my RadPanel and set the .Step property to 1. Now I want to perform the step...but I don't see any PerformStep method available??

The "Track and Status Controls" example show incrementing the Value1 property by 1...but that doesn't make sense since we've set the Step property to 1 already.

[Solved] How to set focus to a control withint a RadTabStrip?

Hopefully an easy question.. I would normally use me.textbox1.focus() to set focus to a textbox control when first opening a form so that the user does not have to click into the box to begin typing.. When I put my controls onto a RadTabStrip, and at the very last line of the form_load event I try to set focus to a control in this way, it does not work.. After the form is loaded I can get the focus to work.. For example, on button click.. But for whatever reason it refuses to work on form_load for all forms in my project.. What am I doing wrong?

Tabstrip (obsolete as of Q2 2010)

RadLabel formatting

I'm looking for a way to alternate formatting within a RadLabel. Something similar to "Found <b>8 results</b> for 'Bob'".

I saw another post that suggested custom drawing in OnPaint, but I don't want to have to calculate wrapping, etc. myself.

Auto data type assign to gridview column

Hi,

I am trying to get data from excel file to the grid at the runtime. The way I am doing this is that I get all data into untyped dataset and then bind it to the grid. The problem I am facing is that when data is bound to the grid if the data in first few rows of specific column is a number then it expects all the data in that column to be number, however it can contain string value as well. Is there a way to stop grid from automatically assigning data type to the column??

Thanks in advance for help.
