Can't programmatically set position of splitter

Hello,

I have a Windows Form application with a Telerik splitter. I would like to put a limit on how much the splitter can be dragged up. I've been searching high and low for a solution to this problem and I can't find anything. The closest I've come is this site here: http://www.telerik.com/forums/programmatically-setting-size

It recommends setting the AbsoluteSize of one of the SplitPanels. So I set up a moving event handler and did this:

private void radSplitContainerMain_SplitterMoving(object sender, SplitterCancelEventArgs e)
{
RadSplitContainer splitContainer = (RadSplitContainer)sender;

if (splitter.Location.Y < 420
&& splitter.Location.Y > 0)
{
splitContainer.SplitPanels["splitPanelMainChart"].SizeInfo.AbsoluteSize = new Size(
splitContainer.SplitPanels["splitPanelMainChart"].SizeInfo.AbsoluteSize.Width, 100);
}
}

This doesn't do anything though. I am still able to drag the splitter way below 420 and it doesn't seem to reposition it.

Can anyway help me out?

EvalFormTheme

I downloaded the trial version and the only 3 theme options I get are Reset, ControlDefault and EvalFormTheme

Regardless of which theme I drag onto the form.

Do themes not work in the trial?

Thanks.

RadDropDownList: MouseEnter event for the entire control

Hi,

I would to ask which element in RadDropDownList control where if I invoke the MouseEnter event, it able to capture the entire control.

Upon trying, each element only cover parts of the control. So when I have MouseEnter and MouseLeave, after mouse hover on the dropdown border, MouseEnter will be invoke immediately, but then at the same time will invoke MouseLeave immediately even though the mouse pointer still within the RadDropDownList control.

I appreciate your help on this.

Thank you!

Autosize LayoutControls

Hello,

is there a way to enable autosizing on LayoutControls or LayoutGroupControls?

The designer shows Autosize and even AutosizeMode properties, but they dont seem to be working... I'm trying to add a radgridview to a LayoutGroup. The grid is going to show different amounts of rows thus having a variable height. I would like the surroundind LayoutGroupControl to wrap around the grid and match its height accordingly.

Kind regards,

Andreas

Visual Studio Conversion tool not appearing in menu

hi I'm running visual studio 2019, with Telerik Winforms UI 2019.2.508.40

I'm trying to convert an existing VB project to Telerik controls, but I don't see the menu option for the converter tool. (Under Extensions->Telerik->Telerik for WInforms, I see a bunch of options: Configure project, AddRad** References, and AddRad** Forms, but no option to convert. (In a new or existing project)

I have read this thread: https://www.telerik.com/forums/convert-your-existing-application-to-telerik-ui-for-for-winforms-does-not-work

with no luck.

I have tried adding the Telerik Winforms VsExtension through the Extention manager but it is not showing anywhere that I can find as an option to install.

Running
C:\Program Files (x86)\Progress\Telerik UI for WinForms R2 2019\VSExtensions\VS2019\Telerik.WinControls.VSPackage.vsix
reports that:
"This extension is already installed to all applicable projects"

Any ideas? Thanks,
