I have created a custom PropertyGridItemElement for my RadPropertyGrid to hold a button.  When the user clicks the button, the click handler performs some action, but the action is based on data that is known by the form that contains the propertygrid that contains the custom element.  How do I arrange for that data to be available to the button's Click handler?  The constructor of the custom element isn't even called explicitly -- it's implicit in 

PropertyGrid.CreateItemElement += (sender, args) =>
{
    if (args.Item.Name == nameof(LabelWrapper.Button))
    {
        args.ItemElementType = typeof(CustomPropertyGridItemElement);
    }
};

Thanks in advance.

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

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 :)

Hello Team

How to set horizontal scroll position left most in the RadTreeView ?

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)

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.
