I have the following grid (as a sample)

I am trying to alter the text on both the ColumnGroup items and the GridHeader items.

I can change the ColumnGroup text like this (in ItemDataBound):

But when I try to rename the GridHeader (as I have done numerous times before), there is no change

What am I doing wrong?

Hi,

in my web application I data bind a list of simple POCO objects into the grid. In the ItemDataBound event handler I add some additional columns with generated values.

E.g.:

For some reason, on both iOS Safari and Android Chrome, when I or a user scrolls vertically in a listbox, it is "selecting" the item under their finger when they lift it off the screen and have finished scrolling.

I would normally expect a user to be able to scroll vertically in the list and then "tap" an item to select it.

I've seen older threads claiming this was fixed in ~2013 builds, but I'm on a 2016 build and I'm still experiencing the issue.

Also on a side note, scrolling down in listboxes on Android Chrome also seems to occasionally trigger chrome's "pull-to-refresh" functionality, which I'm trying to avoid.

The following code works and updates the literal control perfectly.  When I add the ajax manager, it doesn't update the control at all . Its still Showing Chart...

Hi,  I have a site running on an unsupported version of windows.  I is using older RadControls (i.e. RadAjax.Net2.dll version 1.7.1.0) and functions well, but I need to move it to a supported version of windows server.  Of course any older VS project or installation media or documentation is missing.  I've moved the root directory to the new server and configured IIS as best I can.  I've created a new web project in VS2015The RadControls are not functioning.

Can anyone point me to documentation/resources to troubleshoot the issue.

Thanks

I have a RadAsyncUpload button on my form. When it displays the right border of the Select button is cut off. What am I doing wrong? You can see the table borders so I know I have plenty of room.

Hello,

I was wondering if it was possible to group on the same field twice.  For instance:

If not is there a work around?

I have a class derived from GridTextColumnEditor. It overrides the function AddControlsToContainer. I want the added controls (textboxes) to do a postback. When I have a textbox on my page and set AutoPostBack to true, the resulting html looks like this:

But when added via the GridTextColumn Editor, the html is:

This "RadGridNamespace.AsyncRequest" is not a post back and I don't know what it is or why it would be added rather than the doPostBack. How do I make this work?
