Dear Friends,

Is there a way to manage the tooltip behavior of the calendar?

When I use cell.ToolTipText ="Something" it look Ok, but,  with Long Text it's staying on one straight line!

I wish to be able to Word Wrap the long text so I don't see it all across the screen!

Thanks for any Infos!

I'm attempting to make the treeview in our application work as it did prior to the improvement which has it clear the current text. (i.e. I'd like the editor that gets created to have the old text in it, and that text highlighted). I've got all this down except for the highlighting.

This needs to be done programmatically, as some nodes do not have an option to be renamed.

What I'm doing currently is: after the treeview acquires an editor, setting the text value of that editor to the value that was the node's text. I can't, however, find an editor that has any kind of "highlight text" feature, to pass to the treeview when EditorRequired is raised. What can I do to implement this feature?

Thanks in advance,
-Alan

I have a gridview column for full name which is made up of two fields from a database (first name + last name). When I go to edit rows in the grid, I would like display text boxes for first name and last name instead of the concatenated full name which isn't something I can edit directly. Is there a way to do this with the radgridview?  I've done something similar with NestedViewTemplate on the web side, but I'm not sure how to create this type of funcationality with winforms. Any help would be appreciated!

The RadForm Title Bar is cut near the close,max,minimize button, when i load the mdi RadForm in RTL with ar-SA culture thread.

I have tried many different ways, but i'm not able to fix it.

how to get Group Header name as Summary row name. Please finnd the attached image for more clarification

I'm binding a GridView to a datasource with Date/Time fields which may be null or empty. I'd like to either display "none' or a blank string in the column, but no matter what I do it always shows up as "1/1/0001 12:00:00 AM".

How can I at least hide this text?

Hello ,
I developed a rich text box user control fro my application purpose. However, for each form or user control I added it, a code block is getting added automatically in designer file. Following is the code block:
radDocument1.DefaultStyleSettings = styleDefinition1;
radDocument1.DocumentContentChangedInterval = System.TimeSpan.Parse("00:00:00.0000100");
radDocument1.HyperlinkNavigationMode = Telerik.WinControls.RichTextBox.HyperlinkNavigationMode.CtrlClick;
radDocument1.HyperlinkToolTipFormatString = "{0}\r\n{1} to follow link";
.......
The main problem is with the statement radDocument1.DocumentContentChangedInterval = System.TimeSpan.Parse("00:00:00.1000100");
This line causes a run time exception saying the interval should not be zero.
However, if I try to change the value, it gets automatically reset every time if a deign change occur on form/control.
So, I need to look for this entry and change it to some non-zero value before every run.

Please help me out to get rid if it.

Thanks

Hi~
my winform version is 2012.1.321.40
In office2010blue theme should not change the button's font.
but another themes are change good.
only office2010blue theme should not change the button's font.

what can i do?

I use an errorprovider on a radform to show input errors to the user. I can use it with a radtextbox when the validating event is triggered like so:
Where txtBox is a RadtextBox.

2 problems I encounter when using a CommandBarTextBox:
first: raising the validating event
second: using the SetError method of the errorprovider to link it to a CommandBarTextBox.

I tried adding the validating event in the form_load event:
But vs2010 throws me a compile error:
Argument not specified for parameter 'sender' of 'Private Sub txtPIN_Validating(sender As Object, e As System.ComponentModel.CancelEventArgs)'.
Argument not specified for parameter 'e' of 'Private Sub txtPIN_Validating(sender As Object, e As System.ComponentModel.CancelEventArgs)'.

Not being able to use the errorprovider, a work around using the commandbartextbox border forecolor is an acceptable solution. But not being able to use the  validating event of the CommandBarTextBox, I can't work around that one...
