Hello,

So here's my problem : I have 2 GridViewComboBoxColumn, let's call them cb1 and cb2, filled by default. I want that if I select a value in cb1, values in cb2 change ; if I select another value in cb1, values in cb2 change again.

To do so, I wanted to .Clear() my ObservableCollection<String> which is bound to my cb2, and then to .Add(new String()).

The problem is that an OutOfRangeException occurred on the .Clear() function. I saw somewhere that it was because I can't change anything on a property which is bound to the SelectedValueMemberPath property of the comboBox ; that's why I removed this row in my code. Now it works, I can empty and fill my ObservableCollection, but I can't get the selectedValue in cb2 anymore.

 Here's a sample of my problem, though I couldn't do anything for the dataSet which is filled by an Sql query in my code. Instead, I kept only one column inside, "reference", which represents the reference of the cameras used in my grid, in cb1. Values in cb2 are set in the Resources class.

Thanks for your help !

Hi.
I've been playing around with the TreeListView, which I like very much.
However, I notice that when enabling the brushes, the lines are broken when the row height becomes bigger than default (for example, a cell has a lot of text so the row height doubles).

This is the code (and I've attached a screenshot) :

<Grid DataContext="{Binding Source={StaticResource SampleDataSource}}">
         <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>
        
        <telerik:RadTreeListView AutoGenerateColumns="False"
        TreeLinesVisibility="Visible"
                                 ItemsSource="{Binding People}" Margin="10">
            <telerik:RadTreeListView.ChildTableDefinitions>
                <telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}" />
            </telerik:RadTreeListView.ChildTableDefinitions>
            <telerik:RadTreeListView.Columns>
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Width=".3*"
                                    Header="Name" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding SurName}" Width=".3*"
                                    Header="Surname" />
                <telerik:GridViewDataColumn DataMemberBinding="{Binding Address}"
                                    Header="Address" TextWrapping="Wrap" Width=".3*"/>
            </telerik:RadTreeListView.Columns>
        </telerik:RadTreeListView>
</Grid>

Hi,

I have noticed that when you move your mouse over a cell it changes colour. Is there a way to bind to this cell? I have other edit boxes on my form which I want to update depending on which cell the mouse is over. Ie as you move your mouse over the different cells, values in other edit boxes change.  I am not explicitly selecting the cells by clicking on them, just moving my mouse over that cell.

Hi:

I have attached a sample project with a RadWindow as the MainWindow of an app with an issue:

- I have two screens. A primary screen, and the second by the right of the primary screen.
- When I run the app it appears in the primary screen,
- Moving the app to the second screen,
- Click on Maximize button.

What I see is that the windows appears to get a width greather than the second screen width, I guess the width setted in the windows is primaryScreen.Width + secondaryScreen.Width.

One interesting thing it happens, is that if I set the second screen as primary screen, this behavior does not occur.

Am I using the RadWindow in a wrong way or it is a bug?

The attached file is a zip, but I can not attach it as .zip, so I have change the extension to .jpg, please rename it to .zip.

Thanks!

Hi,

Currently Telerik provide the Expression Dark Theme. Would you able to implement the Expression Light theme as well?

I am guessing it would be just be a copy of the Expression Dark Theme with the colours changed.

Thanks

I have a RadGridView in which I have several groups. Each group contains editable rows. A tooltip is bound to these rows via style. Since the binding for tooltip is canceled after an editation, I hardcoded the ToolTip on EndRowEdit event. But this approach only works if a row virtualization is turned off. If I turn the virtualization on and edit a row then each n-th line will display the same tooltip.tak takhle?

Style for binding:

How can I set the background color to the Pivot field selection list to a color other than white. For example if I use the OFFICE2013 Theme and set my  window background to black and foreground to white (we need a white on black effect) then the Pivot grid field select list has a white background and white foreground hence the fields disappear. How can I change the color of JUST the field select list (i.e. the control titled 'Choose fields to add to report') to something other than white. The 4 select lists at the base of the screen style correctly i.e. a black background and white foreground)

Thank you

I am trying to find a way to change the background color of JUST THE TABITEM HEADER - i.e. the background color of the control you click to change tabs. I have managed to change every other background and foreground color of every control using styles with the notable exception of this one.

Can someone please tell me the secret to achieve - any code examples would be appreciated

What's the best way of disabling the ability for viewers/users to add relations between tasks?

Is there a way of doing it similar to disabling drag-and-drop/resizing?  (over-wrote CanStartDrag, CanDrop, CanStartResize, CanResize, etc)

With GridViewHeaderMenu.IsEnabled="true" settings, I always get all the columns in the context-menu at right click of header for hide/show. But I would want, not to display a column that I am keeping visible=false always. How to do that. Your help would be greatly appreciated.
