How to update the RadGridView when the filter is set?

I have telerik RadGridView with columns "status", "Name" and a RadButton with name "Update", when the grid is loaded the rows will have different status like "pending" "unread" and "cleared". When user selects a row with status pending and clicks on button "update" the status will change from pending to cleared. The issue is when we set a filter on status column with "pending" only rows with pending status are shown, here when user selects a row and click on update the status changes to "cleared", as the filter is already set, the row with the cleared status also shown. As we update the row it is not removed from the grid.

Hello

I would like to use the RadDataForm as interface for a invoice manager.

Thank you!

Load/Deserialize with GraphSource?

I would like to be able to Load (and Save) a diagram by initiating the operation in the ViewModel.

Currently, I need to inherit from RadDiagram and override the OnOpenCommandExecuted method to have custom Load behaviour. This is fine, except that I would like to Clear the diagram before Loading the saved XML. I can't use the RadDiagram.Clear() method when using GraphSource, however.

Short of implementing my own Serialize/Deserialize in ViewModels, is there a nice way to achieve this currently?

Thanks

Overwriting selection with Shift pressed crashes RadRichTextBox

I've got an empty WPF app with only a RadRichTextBox in there.So my XAML looks like:

<Grid>

<t:RadRichTextBox />

</Grid>

1. I run the application.
2. I type "bug" to the rich text box.
3. I double click on the word "bug" to select the whole word (double click it with mouse, do not select with keyboard)
4. I press Shift and I keep it pressed.
5. I start to type "BUG"

After "U" is typed I get an InvalidOperationException.

Do you have the same problem? Do you know is it a known bug? Is there any fix expected to it?
My build version is: 2013.3.1204.45

Parent property name with nested properties not updating

Hello!

I encountered the problem with parent property name which not updates if I modify child properties.
I have a class which overrides ToString() to return format string of its properties. When I change one of that property I fire PropertyChanged but ToString() never calling again and I see old name of parent property on GUI.
But the name is changing and ToString() is calling on each expanding/collapsing or searching.

Is it by desing or I have to do smth extra?

Here is a sample project with Q2 2013 libs to illustrate the problem.

Get Data by Index

I want to make it so when I select a row in the GridView, i can get the string inside the first column (or 20th).

I am currently able to get ALL the information in the whole row with dataGrid1.SelectedItem.ToString(); and I could just chop that information up by a series of "Substring" operations, but there has to be a better way!

Getting this cell data by index (an integer 0-19) would be okay.

Getting the cell data by column header name would be okay as well.

Is this possible?
