[CLOSED] Combobox value in PropertyGrid
Hi,
When I use a ComboBox as editor in a PropertyGrid, the selected Text is not displayed correctly. I found a post which explained to use a render function for displaying the correct text.
http://forums.ext.net/showthread.php...ombobox-editor
This however only works when the value field has a integer value, not when it is a string. Somehow the selected value will be surrounded with quotes when it has a non integer value. "A" becomes "\"A\"".
When saving the PropertyGrid values, the selected value will have surrounding quotes.
Why is it working this way?
I use Ext.NET version: 2.5.1.25544
An other question: how do I change the width of the first column in the property grid? (I found some old samples on the forum, they don't work with the current version).
Thanks!
Sander
