Is there also a JSON tagger for the SyntaxEditor available?

Hi,

I'm trying to implement a behavior that will enable me to "check" each page of a pageview. The purpose of this is to define witch pages an user can access.

Basically I want to replace the close button with a checkbox, and then somehow be able to write to the console what pages are checked.

Thanks in advance!

Hello Guys,

I'm using Telerik in my winForm Application. I have a RadDatePicker in Form1 and I'm Using Below Code To Chang RadDatePicker Calendar and Format To Persian. 

When I Started the Application in windows 10, every thing was normal and worked correctly but the problem shown when I Started Application in windows 7.

---------------------------------------------------------------------------------------

radDatePicker.Culture = new System.Globalization.CultureInfo("fa-IR");
radDatePicker.Format = DateTimePickerFormat.Custom;
radDatePicker.CustomFormat = "yyyy/MM/dd";
radDatePicker.Value = DateTime.Now;

---------------------------------------------------------------------------------------

I Can't figure out why this problem happens. 

I'll be glade if you can help me.

thx.

Hi there!

I can't seem to be able to fill a radpivotgrid with data without getting a multi-thread error.

I believe the problem is that the object is multi-thread and I am using ABL which is single-thread.

Can't seem to find a proper solution anywhere.

Is there anything i can do to use this object with ABL?

Regards,

Hugo Ferreira.

P.S: I'll attach the error, however, the main line is in Portuguese. Roughly translated it says "You're trying to using a .NET multi-threaded object in a way that it's not supported. ABL cannot be called in a thread that it's not its main one."

Is it possible to resize the image of the Treeview node ?.

I have a 16px x 16px size icon, but I want it to look smaller than it does by default.
I add each node by programmatically.

Thank you

Best regards

When I set a command bar button image at design time, it looks correct.  Its the 16x16 image I am using.  However, when I set it programmatically, it appears to be 32x32.  I'm setting it from an imageList.  I made sure that the image list is 16x16 as well.

Hi

I have a RadGridview that contains some data columns and some image columns and images are in different sizes (refer to attached image). I want to export it to excel. what is the best way to adjust row height and column width (based on image sizes)?

Note1: I think that i should put some conditions on "ExcelexportRenderer_WorkbookCreated" event but can't find the way.

Note2: My images are in binary format ("System.Byte[]").

Hi

I wanted to disable the border of a radSplitContainer. With the theme: office2013Light the following code is working:

            this.radSplitContainer1.RootElement.EnableElementShadow = false;
            this.radSplitContainer1.RootElement.MinSize = new System.Drawing.Size(25, 25);
            this.radSplitContainer1.Size = new System.Drawing.Size(428, 318);
            this.radSplitContainer1.SplitterWidth = 8;
            this.radSplitContainer1.TabIndex = 0;
            this.radSplitContainer1.TabStop = false;
            this.radSplitContainer1.ThemeName = "Office2013Light";

With the theme MaterialBlueGrey, there is still a border on the display.

Do you have any other ideas on how I can disable the border?

Thank you in advance.

Kind Regards

Dominik
