Hi,telerik.
    Here is a problem of the Docking Loadlayout.
    First, click the "Add New Item" button add some panel.
    Second,click the "Save Layout".At this time,click "Add New Item" button can add a panel to Docking.
    Now, click the "Load Layout" button,then click the "Add New Panel" button,there is no panel added to the Docking...
    Oh,the Title should be:"Can't Add a new RadPane to Docking After LoadLayout"

Here is the xaml

Using BingGeocodeProvider without the MapControl

Is it possible to use BingGeocodeProvider without setting the .MapControl property? I'm using Prism with WPF and I want to be able to create the location for the map in the view model, and databind the RadMap control 'Centre' property to my view model 'MapLocation' property. Currently I get the following error.

System.Exception was unhandled

Is there anything accessible like ItemsTemplate?

Hi All!

I've created a DataGrid in "regular" WPF that supports groups and the items within a group are shown in a wrappanel. For this I could use the code below:

<DataGrid.ItemsPanel>

<ItemsPanelTemplate>

<WrapPanel IsItemsHost="True"/>

</ItemsPanelTemplate>

</DataGrid.ItemsPanel>

Unfortunately it is way too slow for us. We would like to handle about a 1000 items and we are evaluating Telerik grid for that but I could not find a way to reproduce what I need. Each item should be represented with an image on the left, three lines of text on the right and a progress bar in the background. Grouping, sorting and filtering of items should be available (or at least not too complex to implement), hence the items source is a ListCollectionView. I did this in the original approach with a cell template and this works fine in both the "regular" DataGrid and in Telerik's GridView, but in the Telerik version I can't make the cell items appear next to each other.

The result should look something like this:

Group one:

Item1 Item2 Item3 Item4

Item5 Item6

Group two:

Item7 Item8 Item9 Item10

Group three:

Item11

So my questions:

Is there a way to access the gridview's ItemsPanel to do something similar, or are there any alternativse in the gridview?

- OR -

Is there a more suitable control for this that can handle this many items and the result can look like the same?

Thanks in advance,

Istvan

how to programmatically scroll to next visible set of rows.

I want to be able to create a button that when pressed will scroll the grid down to the next set of rows that were not visible. e.g. if the grid is showing 10 rows, pressing the button will scroll the grid down till row 11 is the top row.

I've tried using selecteditem but the grid doesn't focus on the row. Also is there a way to iterate through the rows to get their heights so I know which ones are visible or not?

NumericUpDown resets to invalid value

We have a user control which displays a NumericUpDown. The maximum value of the control is set to 100. When the user enters 200, the value automatically changes to 100. When the user control is closed, the value of the NumericUpDown is reset to 200 which is an invalid value. When the user control is reopened, an error appears next to the NumericUpDown control because it's value is really 200 even though 100 is displayed in the control.

We debugged the application. The value of the NumericUpDown stays at 100 until [ExternalCode] is executed at which point the value of the control changes back to 200.

RadRadioButton Hover State

How can I make a set of RadRadioButtons such that their borders do not show until selected or moused over?

For example, see this image from the Word 2010 BackStage. The first item is selected. and when the user hovers the mouse over any item, its hover state is activated. Until then, no border or state is shown.

GridViewComboBoxColumn Update on Change

Is there a way to make the GridViewComboBox column update its backing property on change instead of on lost focus? This is the default property for the combo box but does not appear to be the default in the grid view and setting the UpdateSourceTrigger in the DataMemberBInding to PropertyChanged does not appear to work.
