Rendering/Refresh in Chrome

One of our users alerted us to a problem in Chrome with the RAD grid control. He has about 100 items and after the operation (insert/delete) completes, the grid doesn't redraw. If you move the mouse over the rows, it will redraw around the cursor as you move it. Once you scroll the screen, it redraws the pieces that go off screen. See attached screenshots.

We were only able to reproduce the problem in Chrome. It worked fine in IE and Firefox. I was just wondering if anyone else has seen similar issues. We had not seen such problems before and I wondered if it wasn't something broken in the last Chrome update.

Thanks!

Changing tab text on client

I'm trying to change the tab text in javascript. I thought it would be a simple task but I haven't had any success with anything I've tried.

The first thing I tried was tab.set_text("NewValue"). This set the text property in the tab client object but didn't update the text currently visible to users.

I then tried to get the DOM element for the tab text to update it directly using tab.get_textElement() but that comes back as null.

Does anyone have any idea how to update the tab text so it's updated in the browser?

AllowCustomPaging=true and pagesize

Hi there,

I cannot get the correct pagesize selected when I use AllowCustomPaging="true".
When you look in the code below I can see PAGESIZE_NEW is set to the new pagesize selected (f.e. 50) in the grHit_PageSizeChanged event.
After that it hits the grHit_NeedDataSource event. The PAGESIZE variable is set to it's original value of 25 instead of 50 like the value in the grHit_PageSizeChanged event.

Any idea?

I am using Telerik: 202.3.1016.35.

Regards,

Marcel
