I want to bind/connect my WPF dataGrid to my webservice. Well that is simple, but I have 100000 rows or so in the DB. How can I do "lazy loading" or

Asynchronous fast loading, somthing like the "Client binding 1 millinon..." example.

I also need sorting, only read, no update or insert.

And example on this, preferly with webservice code C#.

Thanks!

If AccessText is used as header of RadOutlookBarItem it works corretly, but the header in the RadOutlookBar is wrongly defined as System.Windows.Controls.AccessText (standard ToString), will you support AccessText there ?

Thanks,

Reorder columns programmatically

Hi,
I'm using a DataTable as datasource of a RadGridView. The columns are automatically created.
I want to set some characteristics to the columns based on information that I get from a db, like header, visibility and column order. For the first two I'm using the AutoGeneratingColumn event and it's working perfectly. I haven't found a way to reorder the columns programmatically.

I tried the ReorderColumns(oldIndex, newIndex), but I wasn't able to get the oldIndex using grid.Columns.IndexOf(e.Column). It looks like grid.Columns doesn't have the complete list of generated columns.

Thanks in advance for your help!
Marco

Is this version of blend compatable with Telerik?

Save and Load Grid settings

In my application I'd like to allow the user to save the grid view so it can be loaded the next time he opens the grid. The view should preserve the groups, sorts, filters, column order, etc. Is there a way I easily achieve this? Do you have an example I can uses as reference?

Thanks in advance for you help,
Marco

How to input data directly in a column

Hello,
I need my application to allow user to directly edit data in a column cell.
In the XAML file I have set IsReadOnly="False".
When the application runs if I double click on it or I press F2 key, the data contained disappears but it is impossible to input anything else.
If then I press ESC the old data reappears.
The column DataMemberPath is set to a Double value, or better, it is a SQL Server "money" data type, inclued in a LINQ data context.

What do I miss?

Thanks a lot in advance.

Showing a selected items Data

I've created a Carousel passing a list using the ItemSource member. What I would like to do is get data from the item that was clicked on. So for example one of the values in the list is title, when I click on an item I would like to pass the Title of the item I clicked. I created a MouseDown Handler but I can't figure out how to get that data.
Thanks in advance.
