Tree view increasing the click - expand area

[FlR]

Please tell us if it's possible to increase the hot zone around a expand/collapse icon.

Currently the mouse pointer must be EXACTLY on top of the icon to expand/collapse a level. Increase the hot zone to include space around the the icon so it is easier to select.

Users complain that it is too hard to select the icon to expand or collapse.

I've attached an image which presents this.

Thank you.

Please let us know if there is any solution.

Hello,

I'm attaching a sample project demonstrating how you could easily change expander style. This is the most easy way for expander customization. The key part to increase the clickable area is to set transparent background of the Grid(s) inside the control template.

<Grid x:Name="CollapsedStates" Background="Transparent">
...
<Grid x:Name="ExpandedStates" Opacity="0" Background="Transparent">

Hope this helps.

All the best,
Hristo
