RadGridView FontSize cannot be modified using the Fluent theme

Hello, Yoan.

Yes, as you said, the theme will affect FontSize effect. I set telerik:StyleManager.Theme=“Fluent” , its setting for FontSize is invalid.
So, how can I modify FontSize if I still use the Fluent theme?

Thanks

Different place for RadPane's headers

Hi there,

I'm new, and I'm currently trying to understand how RadDocking works.

Is there any way that I can put RadPanes' (which is a child inside of a RadDocumentHost) headers in another location?

Unable to hide/remove GridView left border line

I've been trying to use RadGridView to display a relatively simple list of data. No grouping, sorting or even selecting of cells allowed. I tried to customize it to not show any borders or grid lines and use my custom background but I seem to be unable to get rid of a single vertical line along the left side of the grid.

I've tried to do this by turning off all borders and make all of my backgrounds use the dark background color you can see in the image. (a static resource brush named "GsBackgroundDark") I tried to set the default styles of all of the element types that the grid apppears to use (GridViewCell, GridViewHeaderCell, etc). But clearly I'm missing something.

Can you tell me what else I need to do?

I have attached an image showing you what I see. What am I missing to get rid of that line on the left?

Below is the XAML I'm using

RadGridView memory leak issue

Hi Team,

We were previously using the 2017.2.614.45 version of the Telerik controls and were facing memory leak issues with RadGridView. We have hence upgraded to 2018.3.1016.45 version of the controls but still are facing the same memory leak issues.

We use RadPane which is placed in a RadPaneGroup; the pane in turn contains the RadGridView. We have handled the closed event of the RadPaneGroup wherein we do our cleanup operations(unsubscribing RadGridView events, setting DataContext as null). As stated in one of the forum posts, we also do the cleanup operations advised which is given at the end.

Please also find the memory profile report of our application when we closed the RadPane.

Kindly advise.

Regards,

Swapnil Ramteke

private void radDocking_Close(object sender, Telerik.Windows.Controls.Docking.StateChangeEventArgs e)

{

try

{

if (e.Panes.Count() == 1)

{

var pane = e.Panes.ElementAt(0);

if (pane is IDispose)
