Questions on UI for WinForms Forum

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

RadGridView Self-Reference Hierarchy questions

Hello,

I have a couple questions related to RadGridView Self-Reference Hierarchy:

1. Is there a way to use the properties of System.Guid type as parent/child IDs? or only Int type?
2. How to configure a grid to be able to specify the columns manually and set AutoGenerateColumns property to false. I was not able to achieve it.

Thanks in advance!

CheckedDropDownList which is the AutoCompleteSuggest member?

Hi, I'm using a CheckedDropDownList fine, when the user press the Down Arrow key I show the dropdown ShowDropDown().

But I don't wanna it to be shown when the autocomplete is open, like when the user is switching between the suggestions pressing up and down arrows key...

public static bool IsAutoCompleteOpen(this RadDropDownList ddl)

{

return ddl.DropDownListElement.AutoCompleteSuggest != null && ddl.DropDownListElement.AutoCompleteSuggest.DropDownList != null && ddl.DropDownListElement.AutoCompleteSuggest.DropDownList.IsPopupOpen;

}

// the key down event

{

if (e.KeyCode == Keys.Down && ddlItems.IsPopupVisible == false && ddlItems.IsAutoCompleteOpen() == false)

{

ddlItems.ShowDropDown();

e.Handled = true;

}

ddl.DropDownListElement.AutoCompleteSuggest is always null, so I can't find which is the correct property of AutoCompleteSuggest on CheckedDropDownList to check, any help?
