I'm trying to use a RadTileView for a project and it is throwing an exception when I open the tiles. They open for a few seconds and then the following exception is thrown:

The XAML I'm using for the RadTileView is as follows:

Where FieldViewModels is a IReactiveList.

I've searched the solution for RestoreIcon1 and can't find anything, so I can only guess that it's something in the RadTileView itself? Has anyone else had this problem? Can anyone think of a solution?

Hello,

I am working on a gridview with a contextmenu.

For the comboboxes in the gridview I want to add an additional menuitem (beside Add/Delete etc.). In that case I want to do a search on the item thats currently selected in the combobox. I wired up the command to it which works fine, I am now stuck with getting the selected value from the combobox.

I want to use this value to show in my contextmenu, for example "Search Item X", where Item X is the name of the selected item in the combobox, I also want to pass the selected item to my command so I can do the actual search.

I created the code below, but I am getting a binding error stating that SelectedValue can not be found on the GridViewCell. How do I bind to the combobox inside the cell?

Any help would be appreciated.

Regards,

Marcel

I am using implicit styles and want to display a custom error template for RadCombobox. This is my style, It was working fine when i was not using implicit styles, but after that when ever there is an error it display the default telerik error template a red border with tooltip at right top corner.

<telerik:RadComboBox Width="260" ItemsSource="{Binding Policies}" DisplayMemberPath="Name" 
                                 SelectedItem="{Binding SelectedPolicy, NotifyOnValidationError=True}"/>

<Style TargetType="{x:Type telerik:RadComboBox}" BasedOn="{StaticResource RadComboBoxStyle}">
        <Style.Triggers>
            <Trigger Property="Validation.HasError" Value="True">
                <Setter Property="ToolTip" Value="{Binding RelativeSource={x:Static RelativeSource.Self}, Path=(Validation.Errors)[0].ErrorContent}"/>
                <Setter Property="BorderBrush" Value="Red"/>
                <Setter Property="Validation.ErrorTemplate">
                    <Setter.Value>
                        <ControlTemplate>
                            <DockPanel>
                                <TextBlock Foreground="Red" Text="{Binding [0].ErrorContent}" TextTrimming="WordEllipsis" DockPanel.Dock="Bottom" />
                                <AdornedElementPlaceholder/>
                            </DockPanel>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Trigger>
        </Style.Triggers>
    </Style>

Hi,

We have a situation where we have the RadGridView with ComboBoxes in two of its columns. There are two Text columns as well.

If the mouse is kept over a combo box column and the mouse scroll is used, the Grid scroll bar does not fire but the combo box changes selection. However if the mouse is kept above a Text column cell and the mouse scroll is used, the grid scroll bar works as usual. We don't want this disparity. We want the grid scroll bar to work even if the mouse is kept over the radcombobox column cell.

Another challenge is the version of Telerik.Windows.Controls.GridView.dll that we have in our project is 2011.1.0419.35.

I have tried to play with by hooking the OnPreviewMouseWheel event of the RadComboBox that resides in the grid cell. But seems it still makes the combo box scroll.

Any help will be appreciated.

regards,

J

I think I came across a bug regarding the WorkbookContentChanged event. It is fired every time I change a cell, until I use the "drag cell value" feature, and then it seems to be fired only when a new worksheet is created, there are no notifications when a cell is changed (even in newly created worksheets).

PS: I've created a simple example application but I seem unable to upload .7z files. If you still want it, I'll paste the source in a post

Hello,

I have the following TreeListView.

I use IsExpanded/IsExpandedBinding to open a node and I use IsToggleExpand/AutoExpandItems to open all nodes. Everything works correct.

If I reopen my Tree I have to expand all nodes of the last session. So I store the expand state when closing and use IsExpanded to open the nodes when opening. If I open many nodes it is very slow (flickering). And the ScrollViewer does not recalc its correct size. Perhaps the UI refreshes too often.

If I expand all nodes with IsToggleExpand/AutoExpandItems it is much faster and the ScrollViewer resizes correctly.

How can I improve the user experience and the performance when opening many nodes?

We're looking at using the RadRichTextBox in our application. For testing, I have a very simple docx with 2 mergefields

1. One mergefield in the header of the docx

2. One mergefield in the body of the docx.

When loading the .docx using your sample(SaveAndSaveAs_WFP) , the mergefield in the body appears but the mergfield in the header does not.

How can this be resolved? Is this a settings issue?

Thanks
