RadDock cause wrong Form's ActiveControl

HI

I have met a problem about WinForm ActiveControl in Telerik Control - RadDock.

Reintroduce steps :

1.Place TextBox1, TextBox2 on Form.
2a.Place a RadDock on Form.
2b.RadDock task - Dock New Window to Left - toolWindow1
2c.RadDock task - Add Tabbed Document - documentWindow1
3a.Place TextBox3 on toolWindow1.
3b.Place TextBox4 on documentWindow1.

Run the application and test the ActiveControl state (focus the control by control),
ActiveControl of TextBox1 and TextBox2 is CORRECT,
but ActiveControl of TextBox3 and TextBox4 was WRONG.
(see attachment - Telerik ActiveControl err1.png).

Why the ActiveControl are not TextBox3/TextBox4 ?
And Is there have any solution to fix that ?

Code :

private void Timer1_Tick(object sender, EventArgs e)
{
Control CurrentActiveControl = ActiveControl;
string sActiveControlName, sActiveControlString;
//
sActiveControlName = (CurrentActiveControl != null) ? CurrentActiveControl.Name : "(unknown)";
sActiveControlString = (CurrentActiveControl != null) ? CurrentActiveControl.ToString() : "(none)";
//
listBox1.Items.Insert(0, DateTime.Now.ToString("hh:mm:ss - ") + sActiveControlName + ", " + sActiveControlString);
}

Import multiple ICS calendar files

I'm not sure the exact approach, but I'm looking to design a calendar where it imports multiple iCal files and displays schedule in a single calendar. Each ics file would represent a different entity, and I would want to use custom colors to block events for each.

Calendar, DateTimePicker, TimePicker and Clock

Formatstring values problem

I'm a L4G Progress developper and I just use TELERIK Objets in my programs like the RadGridview.
And I can't format my decimal columns in a RadGridView.
Decimalplaces propriety has no effect and all tested values like "{0:C}" or "{###.##}" for the formatstring propriety are not allowed.
May be I miss some classes which allows these values ????
I'm sorry but I'm a beginner with .Net developpement.

Thanks a lot for your answers.

RadTextBoxControl Click Event Prevents ClearButton

The RadTextBoxControl has a "ShowClearButton" property where is True, at the far right end there'll be an "X" button inside the textbox to clear the text.

If the textbox's Click event is hooked to a function and the user clicks on the "X" button, then the "X" will do nothing and the Click event is triggered.

I believe that when ShowClearButton is True, that portion of the textbox which contains the "X" button should not trigger the Click or DoubleClick events of the textbox.

Make tile's text bigger

Hello,

I'm testing RadPanorama for Windows Forms

I love the zooming feature (although having the ability to set an initial zoom value depending on the screen resolution would make it better), however I can't find how to make the tile text bigger.

When I go to the tile's properties, then font and make the font bigger, it automatically changes back to 'Segoe UI Light, 16pt'.
I then tried doing the same on the TileGroupElement itself, but its font always automatically becomes 'Segoe UI Light, 20.25pt'

I finally tried to change the font of the RadPanorama as a whole, and although the value does change, it doesn't have any effect on the tiles.

So how do I go about doing that? Thank you in advance :)

Get back a Closed Document

Hello,

So I have a form with a RadDock control which has a DocumentContainer which has a DocumentTabStrip on which I had created 4 DocumentsWindows

I wanted to do is so that the Main DocumentWindow (dwApplications) will have buttons that will make the other 3 DocumentWindows appear.

Now on the Form Designer I right-clicked and pushed "Close" on the 3 other DocumentWindows that I wanted to make them appear only if a button was pushed.
However, I fail to bring them back either on the Designer or in runtime.
On the designer I just can't see to find those document windows, not in the usual form designer nor in the Advanced Layout Designer

As for runtime, I thought that this would make them appear, but it actually doesn't

dwLoadEmployees.Show()

dwLoadEmployees.Select()

What can I do?

DropDown size on High DPI

Hello.
I have a problem with the size of DropDown on high DPI. Long story short - it completely ignore DefaultItemsCountInDropDown and MaxDropDownItems.

Some DDL in our projects has fixed amount of items, and we set DefaultItemsCountInDropDown to fixed value, to avoid scrolls and empty space when possible.

And it works fine on 100% DPI. But when I change DPI settings in the system the pop-up height is greater than it should be and have empty space if DDL has less then 6 items. And It will show scrollbar if it has more then 6 items.

I believe that only DropDownHeight is used for scaling. By default, DefaultItemsCountInDropDown = 6 and DropDownHeight = 106, and on HDPI It looks like the program ignores DefaultItemsCountInDropDown and always uses DropDownHeight, which was automatically scaled for current dpi. To confirm my assumption, you can manually set DropDownHeight = 200 (for example) and the result will be the same on any DPI.

Below I gave examples of my code and screenshots from different DPI.

MapPoint not resizing

I tried the sample from this link: https://docs.telerik.com/devtools/winforms/knowledge-base/map-point-with-radius, but the mappoint doesn't resize on the map. I've checked the size property and it definitely changed but it seems that it is not reflecting on the map. Other properties like bordercolor or backcolor is working fine. What could be the problem? Thanks
