Is there any way to disable collapsing of RadPanelBar - GroupStyle ListBar?
Because, I want to disable collapsing of exact group element until some action has done. After that, all elements should collapse normally.

Best regards,

Hi,
Can we display PDF or MS Word documents or Simple Text Documents using the Carousel Control?
If yes, can anyone point tme to some samples or codes using which I can do this.
This is one of the requirements and we are evaluating the Telerik Carousel Control for the feasibility.
Thanks.

Hi

I am using the GridView similar to a table, where a long note is displayed as wrapped text over multiple lines. The problem is that the row size is not adjusting to display the entire text.

So I'm trying to use the "AutoSizeRows" property b/c my understanding from reading other posts on the forums is that it should do exactly that, but it's throwing a run time error:

rgvNotes.AutoSizeRows =

True

 

And I get:

System.InvalidOperationException was unhandled

PLEASE HELP!

I want to set CellBackColor of RadMultiColumnComboBox.But how to do this? Thank you.

Hello,

Hi:
I have a problem and maybe an issue.
1. How can I do to validate when I add a new row into a GridView?...
      * I have 2 numeric columns, when I add a new row, I validate that a column is greater than the other column, if not I have to display a message and cancel the insertion.
I try with the RowValidating event, but I can not get the values captured in the 2 columns.
Note: Is to add a new row.
     



2. I have a column of type GridViewCheckBoxColumn and I set the ReadOnly property equal to true for this column, but at runtime I can change the column, and should not be assumed, that because is ReadOnly.

The controls are the new Q2

Thank you!!

I upgraded to Q2 yesterday and am getting a warning that the ExportToExcelML class is obsolete. The documentation for RadGridView has not been updated. Any news on what replaces the ExportToExcelML class?

I have created a raddock-manager with a documentwindow and a tool window. 

I set the tool window to autohide.

When the tool window is visible and it looses the focus it is getting invisible but i can see several redrawing issues when this happens. 

When the tool window is hidden and it gets activated so that is getting visible this happens very smooth. 

Is it possible to change this behaviour when the tool window is hidden so that it is similar to the activating of the tool window ?

Regards,

Ramius
