I would like to know if it is possible to set programmatically a tooltip in the GridViewSelectColumn´s checkcoxes.

Hello,

I'm programmably creating menu items within the context menu.  I assign one a Tag property, but the MenuItem in the event argument that comes back in the ItemClick event has a null Tag, so I'm not sure why that is the case?  The tag is set in the collection of items in the menu....

Thanks.

Hello,
     I am trying to work with the RadGridView and implement the external filter example in your How To section.  I have been getting this error that I cannot seem to figure out.  It happens when I type in the search to box and it occurs with a column header click event.  At first I thought it had to do with saving and loading the state of the grid, but now I am not so sure.  The error is being thrown in the CustomFilterDescription Class on the property FilterValue() and on the line:
Me.OnPropertyChanged("FilterValue")

Here is the error I am getting with the search for. (any suggestions would be appreciated)

Just wondering if there was something like BringItemIntoView(), but that could bring the item exactly to a desired position?

I followed the instructions in another forum post for changing the colors of my pie chart and that worked fine, but the legend colors continued to show the original theme colours.

 

 

My XAML inside the grid resources (I only set the first two colors).

 

My chart.

Nothing fancy, but the legend doesn't color correctly.  I saw another post that mentionned the data series naming & legend items naming have been decoupled in the latest release - so I am assuming that also the colors were seperated as well, but I can't figure out how to change them.

I have this event handler:

With Q1 2010 themes no longer render correctly no matter which one is specified.

I'm in the process of testing out the telerik rad controls for WPF and trying to decide if these controls best fit my needs.
Currently I'm testing the RadDocking and what I'm looking to accomplish is, have any panel I put in have the ability to fill the container and then the next panel would split depending on where I dock it.

Example:
If I have two floating panels and if I drag and dock the first left, it will dock left and fill the whole RadDock, then if I take the second panel and dock bottom, it will split the first panel and appear to be on the bottom. then I'll continue to dock like this until the interface is built(with additional panels.
Also I'd like to not have any DocumentPanes, I don't want to see tabs unless I fill one panel inside another.

Hopefully this makes sensem I'd appreciate any example someone can provide to accomplish this.

thanks steve

It seems like there are a 2 problems if you try to validate your data by using IDataErrorInfo.

- The UI doesn't get updated properly. I set the background to red for a test and added a breakpoint at the validation part of the code. The code gets validated properly but the background stays red once the error is resolved.
- If you enter a wrong value the text gets moved to the top left corner of the cell and you aren't able to edit the cell until you press escape.
