Make GridView Vertical Scrollbar Wider (Material Theme)

[Joshua]

I have been trying without success to edit a copy of the Material theme for RadGridView in order to make the scrollbars wider.  I have been able to make the outer part wider, but not the inner bar. (that you drag)  Would you happen to have an example?  I would also accept changing the scrollbars globally. (I have tried that too but with no success)

I did try to follow the steps in https://docs.telerik.com/devtools/wpf/styling-and-appearance/how-to/styling-apperance-styling-scrollbars

but have had no luck with that either.  Advanced WPF styling is still bewildering to me or I might have been able to figure this out on my own.

Hello Joshua,

I've prepared a small sample project demonstrating how to increase the width and height of the vertical and horizontal scrollbars respectively.

Please have a look and let me know whether you're able to integrate this in your project as well. I look forward to your reply.

Thank you Dilyan!  That works a charm!  It looks like the secret sauce was:

<Style x:Key="ThumbHorizontalStyle" TargetType="Thumb" BasedOn="{StaticResource ThumbBaseStyle}">
    <Setter Property="Height" Value="45"/>
</Style>
<Style x:Key="ThumbVerticalStyle" TargetType="Thumb" BasedOn="{StaticResource ThumbBaseStyle}">
    <Setter Property="Width" Value="45"/>
</Style>

I had modified many other parameters in my attempts but I hadn't noticed that one.  It is very difficult when looking through a theme to identify which parameters apply to which parts.  Thank you again!
