I have disabled the context menu for a RadRichTextBox via Xaml like IsContextMenuEnabled="False".
Still a context menu is shown, it look's like a part of the ribbon to set font properties.
You can choose font, background and foreground color, bold, italic etc.
I would like to get rid of this context menu as wel, is this possible and so yes how?

Hy,

If i have 20 TileViewItem in my TileView as an Example, a Scrollbar automaticaly appear.
Is it Possible to Activate the Pan Feature to this Scrollbar. I need that Feature for a Tablet App

Thank

Hello telerik support,

this morning i switched from 2011.3.1220.40 to Q1 2012 SP1 and since then the synchronization between GridView
and DataForm rises an exception (Parameter count mismatch).

The first attempt was to switch from OberservableCollection to ICollectionView but that's not the problem.
My project references the sp1 files, but could it be that the versions are mixed during execution?

regards
Chris

Stacktrace:
Parameter count mismatch.

Hi,
I have a problem when using commom column header, I got a null reference exception,
I'm using pdb files to debug telerik gridviiew dll and exception occurs in CommonHeaderPresenter Class and ArrangeLowestHeaders() method.



To get this bug , set  ColumnGroupName property of the first column of your grid to string.empty or set the first groupName to string empty.
Because lastGroupName = groupName = string.empty,
lastCommonHeader is not initialized and you have a null reference exception at line 142.

XAML


I would like to get IsEnabled from Button to set property of Checkbox in Radgridview but when i use code above it not working
please help.

I have a screen that contains a radgrid on it, when the user clicks to add a new record and they enter the new info I do a check to see if it is a possible duplicate.  If it is I want to display a Confirm message box that will inform them that it is a possible dup, but allow them to add the record.
I am currently using a messagebox but would like to use a radwindow, but when I add an even hadler I do not see a way to pass the data to the new method.  Or should I try and read the active row of the grid after the confrim?

Hi,

How to insert the data into the specific row on gridview?

Regards,
Clare

I have a GridView which the user can Delete rows from.  This works on the screen but I need it to fire a stored procedure to delete records form the data base.  I and using the Deleting Event but I am unsure how to get the data from the items being deleted.  I want to retrive a cell value to pass as a paramater to a stored procedure to delete records from the database.

Are following changes possible
To change color of :  (please view the attached image)
1. View Selector which is currently black
2. Date Header which is currently grayish
3. Task color

To change background of a occurrence of a Task, like in a recurrence task if some occurrences have been completed then there background will be different than those which yet to be started/completed. Similarly for Non - recurrence tasks

If above changes are possible please provide some code to accomplish them

Thanks

BringPathIntoView vertically scrolls my treeview so the end path item is "in view", however the item is hidden to the right because the treeview is in a narrow container.  How can I get the treeview to auto scroll horizontally over so the item is truly in view?

Thanks
Buzz
