Display RadGridView after column widths calculated

[Peter]

Hi,

My RadGridView correctly calculates the column widths, but (and this could just be because of my computer speed) there is a quarter-second lapse where the RGV is displayed with the columns all bunched up. It's cosmetic, but I'm hoping to get rid of that. I'm assuming the lapse is while the RGV calculates the column widths thus unavoidable, so is there a way to hide the view until it is done?

Thanks

Hello,

 Can you post more info about your setup and the grid version?

Ok. I've removed some of the columns and converters as they're just more of the same. By version, is 2012.1.326.40 what you're after.

Hi Peter,

 
Unfortunately, we were not able to reproduce the issue using the details you provided. May I ask you to open a support ticket and to send a simple runnable project demonstrating it?

Thank you in advance.

Kind regards,
Vera

I just made a localised project for the problem and I couldn't reproduce it either. The difference between it and the main project is the amount of data displayed as well as the use of the RadGridView within a RadTabItem. If I find time later I'll try recreate the error in a bigger demo project to send you.
