Hi,

In my application,I have a combobox in a window, in which some numeric values are there to set zoom for the application.
when I Click on the combo box and than click on the restore button of the window, I get a window that ask for RadTreeViewItem.Events.cs file.

It gives follwing code at disassambly.

c:\Builds\WPF_Scrum\WPF_Team\Sources\Development\Silverlight\Telerik.Windows.Controls.Navigation\TreeView\RadTreeViewItem.Events.cs
00000000 push        ebp
00000001 mov         ebp,esp
00000003 sub         esp,8
00000006 mov         dword ptr [ebp-8],ecx
00000009 mov         dword ptr [ebp-4],edx
0000000c cmp         dword ptr ds:[075A0B60h],0
00000013 je          0000001A
00000015 call        6D42ADF1
0000001a mov         ecx,dword ptr [ebp-8]
0000001d xor         edx,edx
0000001f call        005A8148
00000024 mov         ecx,dword ptr [ebp-8]
00000027 call        005A78F0
0000002c nop
0000002d mov         esp,ebp
0000002f pop         ebp
00000030 ret         4

after this my application get crash.Can anybody help me out to find the reason behind this.

***Application works well if Combo's IsEditable= False,but if it is True application gets crash.

Thanks,
Anshul

How to set DataLoadMode to work

Hi
I have an async data source in my ViewModel class.
I want to force the grid to show it's animation.
I set that DataLoadMode property to Asynchronous but it's not working (the grid don't know that there is background operation)
How can I make it work?
(In silverlight it was IsBusy state but here it's readonly )
Thanks
Adiel

GridViewLoadingIndicator

Hi

Is there any documentation on using this feature (I'm assuming this will allow us to show some animation whilst the grid is loading data)?

Button Column with command binding

    
                                <telerik:GridViewDataColumn Width="25">  
        
                                    <telerik:GridViewDataColumn.CellStyle> 
        
                                        <Style TargetType="telerik:GridViewCell">  
        
                                            <Setter Property="Template">  
        
                                                <Setter.Value> 
        
                                                    <ControlTemplate TargetType="telerik:GridViewCell">  
        
                                                        <Button   
        
                                                        Command="{Binding IngredientDeleteCommand}" 
        
                                                        HorizontalAlignment="Center"   
        
                                                        VerticalAlignment="Center">  
        
                                                            <Image Height="20" Width="20" Source="/CakeBoss.WPF;component/Images/delete.png" /> 
        
                                                        </Button> 
        
                                                    </ControlTemplate> 
        
                                                </Setter.Value> 
        
                                            </Setter> 
        
                                        </Style> 
        
                                    </telerik:GridViewDataColumn.CellStyle> 
        
                                </telerik:GridViewDataColumn>

I've got a column that is for deleting a row, and I'm using MVVM so i'm binding to a command instead of using the click event on the button. The command does not fire from inside the grid, but the Click event does. If I copy the button outside the grid the button works just great. Any clues?

Drag, Drop, and IndexOf

I am populating a treeview control from a database. I want to allow the user to drag and drop nodes to arrange the nodes in a sort order. I was trying to use the DragEnded event to get the new position in the tree and update the new position in the database. I thought I could use the IndexOf to get the new position in the tree the node is located. If I drag a root node the Items.IndexOf for the dragged node returns the correct position, lower level nodes return -1. The code I am using is as follows:

    
                Private Sub RadTreeView1_DragEnded(ByVal sender As Object, ByVal e As Telerik.Windows.Controls.RadTreeViewDragEndedEventArgs) Handles RadTreeView1.DragEnded  
        
                    Dim newSortOrder As Integer 
        
                    Dim parentId As Integer 
        
                    Dim draggedItem As RadTreeViewItem = e.DraggedItems(0)  
        
                    Dim eStore As eStoreDataDataContext = New eStoreDataDataContext  
        
                    If IsNothing(draggedItem.ParentItem) Then 
        
                        ' no parent then item is root node  
        
                        parentId = 0  
        
                    Else 
        
                        parentId = draggedItem.ParentItem.Tag.ToString  
        
                    End If 
        
                    newSortOrder = RadTreeView1.Items.IndexOf(draggedItem)  
        
                    MsgBox("parentId = " & parentId.ToString)  
        
                    MsgBox("newSortOrder = " & newSortOrder.ToString)  
        
                End Sub

I am using the tag property to identify the parentId value in my database table. Does anyone know why the Items.IndexOf returns a number corresponding to the order the item is displayed in the tree for root node items and -1 for all other nodes?

Thanks.

Scrolling a cell into view

I see there's an API to scroll a record into view:

RadGridView.ItemsControl.BringRecordIntoView

But I also need the ability to insure that a specific cell is also in view (if the grid has horizontal scroll bars), but I see no public API to do this.
