I have a from with a number of RadButton elements each of which contains a square Image.

When the application is maximized I want all of the images to remain square when the elements are resized.

Can I re-adjust the sizes after the RadButton elements are resized?

If not, can I lock the aspect ratio of the Images so that resizing the RadButton elements does not distort them?

I am having an issue with the filter option crashing with radgridview.

To reproduce, create a radgridview as I describe below.

Run the program

Quickly click around in the cells of the table a few times, making sure to drag your mouse a bit so to select a few rows on some of the clicks.

Then quickly click the filter. (sometimes takes a few tries)

I get the following error

System.NullReferenceException: Object reference not set to an instance of an object.

To create the grid do the following.

 Make a RadGridView with the following options (not sure if all are important but the filter and multiselect are) 

this.gridConnectedSessions.MasterTemplate.AutoSizeColumnsMode = Telerik.WinControls.UI.GridViewAutoSizeColumnsMode.Fill;

this.gridConnectedSessions.MasterTemplate.EnableAlternatingRowColor = true;
this.gridConnectedSessions.MasterTemplate.EnableFiltering = true;

this.gridConnectedSessions.MasterTemplate.MultiSelect = true;

(leave the rest as the default options)

Add 3 columns to the grid

Add 5 rows of data to the grid (I used the following)

radGridView1.Rows.Add("test1","test1","test1");
radGridView1.Rows.Add("test2", "test2", "test2");
radGridView1.Rows.Add("test3", "test3", "test3");
radGridView1.Rows.Add("test4", "test4", "test4");
radGridView1.Rows.Add("test5", "test5", "test5");

Any help would be appreciated, thank you.

This is a question specifically for WinForms but the question is the same as below: 

http://www.telerik.com/forums/radgridview-scroll-position-reset-after-rebind 

Basically, what object and parameters do I have to access within the RadGridView to get my scroll position, so that I can reset it to that position after a rebind.

Hello Telerik,

I tried to translate the control into german.

How can I prevent the behavior, which is shown in the picture. (Wordwrap and cut off).

Greetings

PS: Yes, we used also font scaling.

Hi,

 In my code I'm adding appointments to a radScheduler like this:

 Dim app As New Appointment

app = New Appointment(Convert.ToDateTime(dr("StartTime")), Convert.ToDateTime(dr("EndTime")))

app.ToolTipText = "Some text"

How can I set a delay time for the tooltip, i.e. how long the tooltip text is displayed?

Regards,

Pirjo

How do I prevent a ToolTabStrip from being disposed when it has no child panels? I'd like to allow users to redock child panels into a ToolTabStrip even if there are no child panels left.

At the moment I am getting an error "Changing children collection of an already disposed element" when the redocking is attempted.

Thanks,

Hello.

After a few tries, I came to a method that dynamically changes shades depending on the amount of characters MaskedEditBox:

I hope it helps.

Is it possible to set the displayed text of an appointment to be right justified? I am using the scheduler control somewhat differently, with only one appointment displayed for each day, and the text of the appointment is simply a number that tells the user the number of openings on that day. Clicking on the appointment displays further details in other controls. For the text, I am setting the Summary property of the appointment (although I could do something different if necessary).

Numbers are typically right justified, and I would like to do this in the displayed text of the appointment.
