BindingListCollectionView Position not updating

I am binding a GridView to a BindingListCollectionView. This is being filled by a Linq Query.

I am displaying a GridView of a few fields and a set of text boxes that also display these fields and several others. The Idea is for GridView to provide Sorting and Filtering on the key fields and make the rest of the fields visible when the record is displayed.

This works great if I navigate the GridView with the keyboard, but as soon as I use the mouse to select the record instead of the keyboard aarow keys, the position in the BindingListCollectionView is not updated.

To recap, the BindingListCollectionView position is updated when the grid is navigated with the keyboard arrow keys, but not when rows are selected with the mouse.

Any Ideas on how to work around this problem?

[Solved] Dynamic columns but hide some

Hi, I'm have an unusual requirement here. We want to bind the gridview to any strong-typed objects but at the same time, we're not going to hide some columns. So this basically precludes us from defining columns in XAML. So my option is to handle an event which is fired during the creation of columns. There I could probably suppress the creation of some columns. Is there such an event?

gridview-multiple-selection

http://www.telerik.com/help/wpf/gridview-multiple-selection.html

In the above link API, RadGridView has a

ObservableCollection<object> SelectedItems

property. I have a requirement where I need to access the selected grid items in the ViewModel. How can I do that? There is no dependency property for that I can use, and in the code sample you only have codebehind example. Please advice.

Thanks!

Sources for RadBook

HI.

What are the different sources that can be used for the RadBook? I know that you can use images, but what else?.
Can you use a word/ppt/pdf document as a source? Up to now, I had to convert all pages to images, load them in an observable collection, and point the collection as the source for the RadBook.

Can I assign a word document as a source, without doing any conversions?

Regards

[Solved] Hide Tab Item Header

We have a requirement to drive our tab control from elsewhere in the application, and so, the header tabs have become unnecessary.

Is there a way we can hide the tabs in a RadTabControl? Or, is there a better control for our needs?

Hello,

I am using RadGridView for WPF. After changing cell's value in the grid and selecting another control (for example dropdown list or button on the same window) row is still in editable mode and changes in the cell is not applyed to corresponding model (I am using default binding). How could I force Grid to switch from Edit mode back to view mode on losing focus or when some command is executed (for example, command that is binded to the button).

Thanks,
Alexey Smirnov
