I have the checkbox control set to isthreestate=true. In design mode when I toggle the states for their initial values, the image is correct. However, in run-mode, the image for checked and indeterminate both show the check mark. In the ToggleStateChanging event the property is correct, but visibly it is incorrect. (To recap, both ToggleState.Inderminate and ToggleState.On show the check mark.)

This happens with all of the built-in themes. I'm on a machine with Windows 7, 64-bit.

Did a search but didn't find anything. Ideas?

Buttons, RadioButton, CheckBox, etc

DateTimePicker and MinDate

I am encountering 2 issues with the DateTimePicker and MinDate.

I can not select the minimum date from the dropdown picker. For example, if MinDate is 12/10/2010, I am not able to select that as the date, instead it closes the dropdown and enters nothing in the textbox. When this occurs, I am unable to type in the textbox until I pick another date. This does not happen if I click on a date earlier than the MinDate, e.g 12/8/2010.
If I tab into the textbox, I can type in a date earlier than the MinDate. The value does not change, but the display does. Not very consistent UX.

I am using the latest version.

Thank you!

Tabbed Document GotFocus

Probably an easy question but for some reason the Form_GotFocus event is not firing on my docked RadForm. Is there another event I can use to capture when the form receives the focus?

Thanks,

Issue with RadGridView property builder

Hi everyone! I'am using Visual Studio 2010 with Telerik winform Q3 controls. I find one issue. Lets create simple winform application. Add to it radgridview control. In Properties window add some columns, add one template and add some columns for template. Create relation for master and child template in radgridview. Open "Document Outline" window (View->Other Windows->Dicument Outline). This window shows hierarchical structure of the winform. You can see that template is under the gridview. Now edit grdview properties with "Open property Builder". Do some changes and click OK. Now if you look to "Document Outline" window you will see that template is disappeared. Relation between gridview master template and child template is deleted. Why is it so? Is it bug?

Thanks.
Armen.

Hi

RadComboBox has RadCheckBoxElement Items. How can I set backcolor of each item. I try like this:

For i As Int16 = 0 To 5

           

    Dim citem As New RadCheckBoxElement

         

    citem.Text = "Text"

         

    citem.BackColor = Color.Blue

  'set backcolor to blue, but nothing happens          

    RadComboBox1.Items.Add(citem)

Next

But items backcolor remains unchanged.

Problem with Filtering in Virtual mode (Q2/2010)

I think filtering in virtual mode in Q2/2010 is not functional. The same functionality in Q1 is ok. When filter is active (user enter some filter), I don't recieve CellValueNeeded events. When I try to set RowCount in FilterChanged event, I get exception "Object reference not set to an instance of an object."
