I've pasted 26k of data into the textbox and things go really bad.  The max characters for this say it should handle 2,147,483,647, but there is no way I've experienced anything remotely close to that.

The problems:

  Scrolling is choppy and slow

  I can CTRL-A to highlight everything (which is fairly fast), then I right and get the context menu, but I can't ever select Copy.

  Any more data than the above 26k, the control is pretty much just locked up.

To Reproduce:

In order to make sure it wasn't my app causing the issue, I created a new app, dropped a radTextBoxControl onto it.  Resized it to 1218, 828 (randomly chosen), then ran the app.

I pasted the same 26k of data (XML content, but it doesn't seem to matter what it is), and the same issues I first described above happened.

Hi guys, I've experienced a new weird behaviour. In this case the RadSplitContainer makes up his own color.

The UserControl I created still has the default BackColor "Control". Everything else is set to "Transparent". Why is the SplitContainer blue???

why does the spreadsheet lose focus when you make an input? 

How can I guarantee that I only trigger a LostFocus event when I leave the control?

Is it possible to flip arrow in RadDiagram control? Standard arrow is pointing to left side. I need to have arrow pointing to right side. I can set rotation to 180, but then also text is rotated, see screenshot. How can I solve this?

Hi,

I am using the 2011.2.11.712 build of the WinForms controls.  When I set the RadMaskedEditBox MaskType to "Email", it works correctly and shows the icon when the value is invalid.

But, how do I detect in code that the validation failed? 

I have a form where the user enters an email address and I want to detect that the user entered an invalid value and not allow the save but rather show an error message.

Thanks
