As of 2024 Q4 (November), we will deprecate .NET 7 distribution. This decision is rooted in our dedication to align with Microsoft’s recommended framework versions so that our products leverage the latest advancements in technology, security, and performance.  

We are aligning our product with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. Please refer to the following blog post: Product Update for Enhanced Performance and Security (telerik.com)

For more information about how to upgrade your project when a new version of the Telerik UI for WinForms suite is released, you can check here: How to Upgrade a Telerik UI for WinForms Project - Telerik UI for WinForms

Using RadCalendar and I thought is would be simple

I want all dates in the past to be disabled and I thought this would do it:

        private void radCalendar1_ElementRender(object sender, RenderElementEventArgs e)

        {
            if (e.Day.Date < DateTime.Now)
                e.Day.Disabled = true;
        }

Th goals is to have it look like this but it seems to have no effect and I can selected dates that the code set as disabled.

What am I missing?

Thanks

Carl

Hi!

When endUpdate occurs in gridview, the scroll moves to the begin.

In my environment I have to beginUpdate and Endupdate.

But 1 dont' want the scroll to move even if the data is Updated(endupdate timing)!

Please tell me how to prevent the scroll from moving automatically when editing mode is released by double-clicking or when endupdate occurs.

The method of updating the scroll value after endupdate by storing the scroll value before beginupdate failed.

A gif Image and simple project are attached. Please help me!!!

Thank you :)

I'm experiencing weird behavior when trying to remove a row using v2023.3.1114. I created a test form in my main app and launch it like this:

Form1 form = new();

form.ShowDialog();

The form populates a grid  by setting the DataSource to a collection of POCOs.

The grid has a a hyperlink column. When the user clicks the column, the goal is to have the clicked row disappear. I'm implementing it like this:

private void gvTaskNotifyType_HyperlinkOpening(object sender, HyperlinkOpeningEventArgs e)

{
    try
    {
        int rowIndex = e.Row.Index;

        gvTaskNotifyType.Rows.RemoveAt(rowIndex);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }

}

 

Problem is when the RemoveAt() method is called it throws a Object reference not set to an instance of an object . It may happen the first time or more often the 3rd. It also happens if I use Remove() and pass in a reference to the row object and also if I try to set the IsVisible property to false. The really strange part is that the error doesn't enter the catch handler. Rather, its stops on the form.ShowDialog(); line and breaks there.

Any ideas?

Hello!

I was trying to upgrade several programs to have the font connected to the program size ("dynamic" font). I wasn't able to do it in a simple way because i kept finding problems and i assumed it was some minor telerik object bugs. But then i found out that some of the bugs weren't simple to fix because the fix would impact the program performance. So i created a program from scratch to see if the problem was in my program (i could be doing something wrong since it hd a lot of code) but i came to the conclusion that this problem is actually because of the theme and not mine or the programs fault.

When i use a radgridview and change the font to a higher size (ex: 27) some of the text in the grid won't change if i'm using the theme 'TelerikMetroBlue'. But if i use the default theme 'Office2010Blue' the object works great.

Please check the attached images.

Note: I'm only using a radgridview in this example but the problem was also detected in other objects, like radlistview and radganttview.

Hi Telerik,

 

I'm using C# and and RadPageView NavigationBar component for my WinForms application.

I think I'll give a background story first.

I implement a RadPageView with NavigationBar, and also implement a search bar between the hamburger menu and the RadPageView items

The item's is populated from a class

 

The "search menu" is used to filter the displayed menu 



And when I clear the search menu's filter, the RadPageViewItems is re-loaded with the previous class data. But, it takes a long time due to a lot of records (FYI, i have ~1000 menus that equivalent to ~1000 RadPageViewItems)



Is it possible to improve the load speed? Like, maybe, any mechanism that stores the fully loaded menu as a local-storage in RadPageView's function/module that I should call when the search menu is cleared after it has been filled?

Thanks in advance!
