Hi

I'm using a RadRicjTextBox in a WPF with DataBinding and ValidatesOnDataErrors, and I'm trying to add validation to ensure that the user has acutally typed something into the comment



Here is the XAML snippet...

But I'm not sure how to validate the contents in my IDataErrorInfo code, I can't just check to see if the Response field is empty, because as soon as you type anything, and then delete it, the field contains all the HTML wrappings.



Am I missing something or is there a way to do this, I had thought I should try and convert the HTML to Text somehow and then check, but I don't want that to happen with every key press (I'm also not sure how to go about it



Thanks in advance

hi

Is it possible to programmatically set a ColumnGroupDescriptor to allow column filtering. As you can see from my code I am setting IsVisible = false so that I don't show redundant info in each row.  I would like the Group column header to show the filter icon and allow for the column to be filtered.



Thanks

Rich

ColumnGroupDescriptor colGrpDesc = new ColumnGroupDescriptor();

colGrpDesc.Column = grid.Columns[groups.UniqueName];

colGrpDesc.Column.IsVisible = false;

colGrpDesc.SortDirection = sortDirection;

grid.GroupDescriptors.Add(colGrpDesc);
