Hi,

I would like to add a Dropdown in one of my Filtercells. Every entry in the Column should be displayed in this dropdown so the user can choose just elements which are already in the column of the grid. Is there a property to achieve this behaviour or do I have to create a Customcontrol to handle this?

Could you please send me a simple example how to solve this task?

Sincerely,

Dominik Zöbl

RadControl.Font Override

here is the scenario..

I am trying to create some wrapper classes for controls that display text such as labels, etc. What I am seeing is that I am copy and pasting the same font override function for each control.

Is there a recommended way of overriding the RadControl.Font and utilize that? The problem, is the wrapper class can only have a single base class.. MyRadLabel : RadLabel

any pointers would be nice. I hope I am just missing something small that I am not thinking of..

Paragraph p = block as Paragraph;

if (p != null)

{

}

RadLabel <html><color=xxxx>

I'm not using themes in my project yet but I would like this to work as if I were. I'm setting up some RadLabels to contain both the name of the piece of information and the value of it. I.E. RadLabel1.Text = string.Format("<html><color=Navy>Item Number: <color=Black>{0}", theItemNumber);

How can I get the color name for the text at the top of the RadForm (or any control's forecolor that is used to display text)?

Also, where I'm setting the color back to the default for the label, is Black the default or is there some place to find that color as well?

Thank you,

Gary

Reseting Image to nothing implementation

Hello,

I'm using Q1 2017 radcontrols for winforms (vb.net).

I have a radporama with a radtile, and a radpropertygrid, with the radtile as selectedobject.

When i set an image to the radtile using the radpropertygrid, everything works fine. But i dont know how to reset the image to nothing. If i select the image in the radpropertygrid, and the press "delete" on my keyboard, nothing happens.

I need a solution without clicking on the square and reset.

Could you help me?

Thanks in advance.

Best regards.

Text turn to grey after selection

In my grid, text is black. When a row is selected, the text turn to grey (that's ok). But when I move the selection to another row, text on previously selected row remains grey (see picture). How can I make the text turn back to black (its original color). I looked at the visual designer but haven't find the element or attribute that is responsible for this behavior.

Line Spacing

Is there a clean way to set the line spacing for all text in a document (add both via import and user typed)?

I found the RichTextEditor.Document.LineSpacing property, but this appear to set an absolute of the spacing between the bottom of each instead the of space between each line, which would have to be based on font size.

I assume I could use this property and go through line by line looking at the font size and setting it when anything changed on the document, but that sounds like it would result in an excessive amount of overhead.

I'm not looking to use any special spacing or anything like that, just enforce single line spacing on the document regardless of font size and apply to to both imported text and user typed text.

Any help would be appreciated.
