RadDropDownList event handlers returning RadDropDownListElement object

Hello,

I'm using a RadDropDownList control and i've noticed when handling the PopupOpening event, the sender object being passed is a RadDropDownListElement object and not the RadDropDownList control itself. Is there a way to get the RadDropDownList object from the RadDropDownListElement object? I need to get the parent control of the actual RadDropDownList control and i can't do this from the RadDropDownListElement object currently.

I have the same problem with the RadColorBox and its ValueChanged event handler returning a RadColorBoxElement object instead of RadColorBox.

Let me know if you need more information!

Thanks,

Hayley

ColorDialog not on top of Main Form

Hi,

I am trying to use the radColorDialog but its not showing on top of my main form.

The main form is set to TopMost to ensure its at the top (the app has other forms open)

From the main form I am calling:

private void button1_Click(object sender, EventArgs e)
        {
            this.TopMost = true;
            this.BringToFront();

            radColorDialog1.Reset();
            
            if (radColorDialog1.ShowDialog(this) == DialogResult.OK)
            {

            }
            
        }

This is winforms .net7 I am only using this one Telerik control UI.for winforms... (2023.2.606)

I would expect the dialog to above the main form.

I tried the colourBox and it has the same issue.

Impossible to select Rad* component

Hello,

Visual Studio 2019
Telerik version: 2022.2.510.40

When I open a form with Telerik component on it, it is not possible to select it anymore.

No problem with "standard" controls. Only Telerik controls are causing this issue. I have a RadGridView and a RadColorBox.

Any idea?

Thank you!

RadColorBox Scaling Issue

There appears to be a peculiar scaling issue when the RadColorBox is used in a dpi aware app running at scales greater than 100. This can be demonstrated by dropping a RadColorBox on a form in a dpi aware app and then running the app at 150%. Multiple clicks on the colorbox will show the problem. The first click the dialog is at the correct size for that scale. Close the dialog and open it again and now the dialog has shrunk to what is probably 100 scale. And now with each subsequent opening of the color box dialog the size alternates between large and small. Weird, right?

ColorBox color input and output

I have been looking at the ColorBox control, but I cannot figure out how to do simple things. What I want to do is specify the color displayed when the form containing the ColorBox control is opened, and extract the value of the new color chosen by the user.

I expected to be able to specify something like:

radColorBox1.InitialColor = Red;

and then get the new value if there is one.

Apparently one gets the new value from the ValueChanging or ValueChanged event handlers, which is straightforward enough I guess.

I program in C#. Any suggestions will be appreciated.
