2. Select Target Framework .NET Core 3.1, 5.0 or 6.0
3. Convert to Telerik Controls via the WinForms Extensions menu
You will see that you cannot select version .NET Core 3.1, 5.0 or 6.0 from the drop-down.
If you attempt to convert the project by selecting version 2.0 or 4.0 the Visual Studio will crash.
(This request may be specific to VS solutions which produce only DLLs, and not to ones which create a .exe.)
At the moment, the default behaviour for everything else in my VS project is to not produce warnings unless something might be wrong, which I may need to action.
WinForms,as of the latest release (2025) is the only thing which produces warning messages where there is not problem, which is not very tidy. I only want to see things in the build output which need my attention, defintely not 'happy' messages, or warnings which are not needed.
Currently, for each project in my solution, I get a message like:
1> [Telerik and Kendo UI Licensing]
1> Valid Telerik UI for WinForms license found. Make sure the main application also references Telerik.Licensing when using a class library.
...but I have a valid licence, and everything is OK. No action is needed.
Your support suggested adding...
<TelerikLicensingVerbosity>quiet</TelerikLicensingVerbosity>
...to each project in my solution, but that still produces the above build message.
A polite solution would be to turn-off ALL such warning messages, and let me switch them ON when needed. Preferably via a setting somewhere, not by editing the VS project file, which means unloading, editing the project file, and realoading each of many projects.
(Visual Studio 2026, not currently an option in the drop-down below)

RadMessageBox(form) is a telerik replacement for the System.Windows.Forms.MessageBox.
MessageBox has a parameter MessageBoxOptions.DefaultDesktopOnly which makes it (surprisingly) topmost. RadMessageBox does not have this option.
I have a scenario where the RadMessageBox is hidden by a total different application when shown. So I need to make it topmost.
Can you add some kind op RadMessageBoxOptions to make it topmost?

I’m converting 20+ year old c# .net winform software that a clever internal ex dev wrote a themed control suite for. I’ve been working with those controls for almost the same length of time but am recently tasked with updating the whole app as customers are experiencing fall overs on some modern versions of Windows. Ive had the pleasure of (almost quietly ?) converting/updating by using Telerik for many years as my choice of replacement themed control systems.
Conversion experience has been pretty good, except for combo boxes, probably listboxes too (sorry guys Im writing this in bed at 5am so can’t/won’t just go testing). I did try, i think, using your conversion wizards without success. I do wish that you’d let us add any type of object to a combobox.item array in the same way that microsoft winform control allows.
Ive also noticed that some events dont occur in telerik, eg index changed need to be switched to valuechanged and these are only spotted when testing, which means extra work.
anyway. Bless an thanks to you all for my good experience with Progress/Telerik. Im old, poorly and crumbly now and wont be around much longer. May i last long enough not to need a pension to survive and i hope each of you invests in enough private pension to give yourselves a decent holiday or three per year ;)
The issue is reproducible only on Windows XP. On newer versions of windows, the images are rendered as expected. WORKAROUND: You may try implementing custom filter that handles the CMYK scenario. How to implement custom DCTDecode filter is described in this documentation article: https://docs.telerik.com/devtools/winforms/pdfviewer/customize-and-extensibility/customize-pdf-rendering
Hi,
I want to hide some columns of the table I received from Excel on RadGridView.
Hi everybody
I m try use the class CustomDragandDrop on radtreeview but i have a issue,
if i use the next example, i dont have any problem:
protected void BindRadTreeView()
{
DataTable dt = new DataTable();
dt.Columns.Add("Id", typeof(string));
dt.Columns.Add("Title", typeof(string));
dt.Columns.Add("ParentId", typeof(string));
string parentId = string.Empty;
string childId = string.Empty;
for (int i = 0; i < 2; i++)
{
parentId = Guid.NewGuid().ToString();
dt.Rows.Add(parentId, "Node" + i, null);
for (int j = 0; j < 5; j++)
{
childId = Guid.NewGuid().ToString();
dt.Rows.Add(childId, "SubNode" + i + "." + j, parentId);
}
}
this.radTreeView1.ChildMember = "Id";
this.radTreeView1.ParentMember = "ParentId";
this.radTreeView1.DisplayMember = "Title";
this.radTreeView1.DataSource = dt;
}
i can drag and drop correctly
but the problem is when i binding the Radtreeview
protected void llenatreeview1() {
dtTablas = dat.consultaBD();
DataTable dt = new DataTable();
dtCopi.Columns.Add("Id", typeof(string));
dtCopi.Columns.Add("Title", typeof(string));
dtCopi.Columns.Add("ParentId", typeof(string));
string parentId = string.Empty;
string Id = string.Empty;
string title = string.Empty;
foreach (DataRow row in dtTablas.Rows)
{
parentId = row["ParentId"].ToString();
Id = row["Id"].ToString();
title = row["Title"].ToString();
if (parentId == "")
dt.Rows.Add(Id, title, null);
else
dt.Rows.Add(Id, title, parentId);
}
radTreeView2.ChildMember = "Id";
radTreeView2.ParentMember = "ParentId";
radTreeView2.DisplayMember = "Title";
radTreeView2.DataSource = dt;
}
first is freeze and then appears the error.
when i drag and drop appears then next error:
System.StackOverflowException
GridView has a default text alignment for new columns as 'MiddleCenter'.
Default alignment for new GridViewDataRowInfo is 'left'.
Please can these be the same ?
Dear Sir,
I’m a retired computer analyst and program for my own enjoyment.
I recently downloaded your UI for Winforms product and played with your Image editor control.
A very nice control indeed. It does some great manipulations of images.
It would be even more flexible if a user were able to add their controls to the radImageEditor control, have access to the loaded image, and be able to add further options to be able to edit images.
Just a thought.
Kind regards
Phil Sargeant
Dear,
I wonder if it is possible to consult the release history by product & control & version, next to the (already existing) release history by product & version & control?
This feature has benifits:
- see how a given control evolves in time
- quickly find if a bug/feature has been implemented by control
This request can be applied for all your products.
Kind regards,
Peter
Hi guys,
It would be great to be able to set the day start/finish times in your Scheduler.
Your Scheduler control is fantastic, but I am building a Scheduler for a company that operates over 24hrs and the shift hours are
6am - 6pm
6pm - 6am
both shifts are classed as being the same day even though the nightshift crosses over to the next day.
I would like to be able to adjust the 24hr period that defines a day so that in month view the appointment will not carry over to the next shift.
and in day view, the schedule will start at 6am and go through to 6am.
If you could implement this, your scheduler control would be even more powerful and awesome.
Thanks!
Hi,
We are using Telerik UI WinForms in our project. Current built-in themes are not suitable for our project requirements. We need Visual Studio 2019 Theme for UI WinForms.
As mentioned in the Telerik blog, the latest R3 2019 release of Telerik UI for WPF and Telerik UI for Silverlight is having Visual Studio 2019 Theme.
When can we expect Visual Studio 2019 Theme for UI WinForms?
