Hello, sorry, maybe I am too new to Telerik, but I was wondering how to do basic tasks with SyntaxEditor. I wanted to replace classic TextBox with SyntaxEditor and I thought it would be straightforward, but I got stuck on very basic tasks. Can you please help me, or navigate me?

1. How to get text from SyntaxEditor? I know how to set text by setting new document, but how to get text? I read whole SyntaxEditor part of documentation, but haven't found this, how is it possible? I was trying to find this out for about hour, but without success. I am wondering if am too new to Telerik or how it's possible I couldn't find this, I think this basic thing must be like "look and see".

2. Classic WinForms TextBox has Modified property indicating the text was changed. Is it also somewhere here? Also, TextBox has Lines property, is it somewhere here?

3. I tried the Cut/Copy/Paste commands, they are working, but I was wondering why CanExecute methods return always true. For example, I expect if there is no selection, CanExecute for Cut and Copy has to return false. Also, if there is no text in clipboard, Paste command has to return false, etc.

Hi, I'm having strange resizing issues when moving an application between "normal" DPI and High DPI monitors. I have managed to reproduce the the issue in a small project which is attached.

To reproduce the issue move the application between monitor with different DPI's and and re-select the start menu button (blue blank in this case)

Tthis is what I see, it appears there is a resizing issue going on, thi sgets worse the more menu items in the right hand column (recently used file names in my application)

Hello,

We have a project that uses Telerik Controls and that was developed by a user with a valid license.

We would like a second user to be able to modify the project. This second user will not touch any of the Telerik Controls (this will be done by the user with a valid license). According to this post, a user without a valid license should be able to compile the project. However, when compiling on said user (or when restoring Telerik Nuget packages), we get a pop up box (see joined) asking for credentials. The second user does not have any Telerik credentials.

How can this user compile the project?

Thanks,

Guillaume

I have just recently upgraded to the latest version of WinForms (2022.2.622.40), along with upgrading from .net 4.6 to 4.7.2 to take advantage of High DPI updates.

When I start my application, is simply goes away without reporting any error.

I should add that my form has a single RadPictureBox with a small image loaded from the project resource but has defaults for SvgImage. DefaultImage and DefaultSvgImage 

Any ideas? is there a workaround ?

Thanks in advance

Greetings, you can indicate how to change the height of the headers or tabs of a radPageView, it is preferred at design time. if not possible by code.

I'm using Telerik Windows Forms 2022.1.222.40
Visual Studio 2022

Hello, I want to use SyntaxEditor for coloring and folding of my very simple custom language for defining sequence of steps. I have already made some tests and have no problem with coloring. But I have two questions to SyntaxEditor folding. My language is very simple, it's just sequence of steps, but now I have to implement if/else/endif handling.

1. If I add folding pair if/endif, it works ok, but what if I want to fold if and else branches separately? Is it possible to do folding somehow like on this screenshot? I tried similar code it in Visual Basic, VB folds whole section from if to endif, but I would like to do it like on the screenshot, if it's possible.

2. How can I customize the folding "title" (I don't know the exact terminology). I added a #region / #endregion to previous sample, and it's folding like on this screenshot:

I would like it like in Visual Studio, in case of if statement, you can see the condition, but region hides also the region directive, like on the next screenshot.

I know, C# is folding command block with braces, so it's different situation, but is it possible to do it like this also with my custom language?

I attached also my project, if it's needed for something.

Thanks.

Hello, how can I block the arrow keys from the Scheduler so that the user cannot change the month view's calendar?

I have blocked out and set all the days that is not within X month to be hidden, so I do not want the user to be able to use the arrow keys and accidentally change the view.

Also, related to the scheduler, how can I loop through and go through the entire month day-by-day to grab all the appointments?

Something like, for each day in MONTH....

Thank you

Hello,
I am getting to know the RADPropertyGrid control, it seems flexible.
I have an XML file where "Key" would be the property name and "Value" would be the value in RADPropertyGrid. Where required, I also have a value list between the "ValueList" element. My question is, how can I pass the XML so that the value list for that element is displayed as a string in a combobox in the RADPropertyGrid associated with the property?

Can you show me a sample project on how to do this?

Sample XML:

<PictureBox>
    <Property>
        <Key>EnableClickZoom</Key>
        <Value>False</Value>
    </Property>
    <Property>
        <Key>EnableZoom</Key>
        <Value>False</Value>
    </Property>
    <Property>
        <Key>EnableAutoPan</Key>
        <Value>False</Value>
    </Property>
    <Property>
        <Key>SizeMode</Key>
        <Value>Fit</Value>
        <ValueList>
            <Value>Normal</Value>
            <Value>Stretch</Value>
            <Value>Fit</Value>
        </ValueList>
    </Property>
    <Property>
        <Key>Zoom</Key>
        <Value>30</Value>
    </Property>
    <Property>
        <Key>InterpolationMode</Key>
        <Value>Default</Value>
        <ValueList>
            <Value>Default</Value>
            <Value>Low</Value>
            <Value>High</Value>
            <Value>Bilinear</Value>
            <Value>Bicubic</Value>
            <Value>NearestNeighbor</Value>
            <Value>HighQualityBilinear</Value>
            <Value>HighQualityBicubic</Value>
        </ValueList>
    </Property>
</PictureBox>

Would it be possible in the next release to expose the panel border visibility at design time in the properties window, rather than having to navigate through "Edit UI Elements" (or via code). I have a lot of panerls where I don't want to see the border at run time but do need to see it sometimes at design time.

Thanks
