Hi,

I have a RadDaraFilter that has been bounded to a RadDataGrid.
The columns of table are (Name, LName, Tel) in SQL, So, the radDatafilter has been shown ("Name, LName, Tel").

How I could change the field of radDataFilter from "Name" to "Person's Name" or from "LName" to "Last Name", Please?
Thanks

Hi.
I have 7 items in my carouselPanel. It begins to 'carouse' in the middle, so the first item is items[4].
How can i change that, it will always scroll from right to left, with first item, and do something like:
[] -> [] -> [] -> [] -> [] - last item, rewind and again

                ImageBrush b = new ImageBrush();

                switch (i)

                    case 1:
                        {
                            b.ImageSource = new BitmapImage(new Uri("/campus_floorplan;component/images/directory_level1.png", UriKind.Relative));
                            b.Stretch = Stretch.Uniform;
                            this.Background = b;

In GofFocus and LostFocus of NumericUpDown, I've changed the Value of NumericUpDown.
The value changes but no changes is displayed in UI.
If I do some actions that refreshes the UI, (like minimize and restore my window, or show a MessageBox in mentioned events or...) the UI updated.
What should I do?

Hello Telerik team

I have managed to style my rad grid view in WPF accordingly , however when grouping by a column the expanded row has an empty space on the far left which doesn't seem to be a part of any style (see attached file for mentioned left space and the resulting ugly contrast of colors). Can you  please let me know where is this space defined (template ?) and how can I style it ?

Thanks in advance

Kind Regards

Hi telerik,

I am confused how to use RadGridView with VirtualQueryableCollectionView in order for data virtualization, but some issues encountered when I insert a new item, let me clarify.

I use the below code to set datacontext of a window, 

but there are some specified points, the Tax table only have 7 records, those records can show in grid correctly,but if I use blow code for inserting a new item,
           

this new item will not display in grid expect adding this statement
         
But executing this statement will refresh the collection and grid,  I don't want to do this. so my questions are
1. How can I show all records if called insert statement?
2. How to save a new records to database? 
I did this using below statements currently:
         
if I can add use VirtualQueryableCollectionView's AddNew/AddNewItem/Insert add a item to VirtualQueryableCollectionView and then call someone method to save it to database directly without needing executing context.CreateObjectSet<TValue>().AddObject(newItem);
? if yes, could you provide a sample project for me? thanks very much.

Hi,

I have a scatterchart with lots of datapoints.
Values from -100 % to 3 000 000 %.

When I apply zoom to one or more points, the zoom are gets totally wrong.
For example the zoom area could be set to -200 % -400 %; even though I zoom on a point that had a positive number.

This issue applies to both axes, every time I zoom.

Any ideas?

Hi,

I have 8 RadGridViews in my wpf application. I have used some properties of the RadGridView in the below code snippet. Each RadGridView is added inside an Expander.

When I select an item in a tree view, I change the Datacontext of the Expander. But the rendering of the control  takes too much of tne time. How do i improve the rendering performance of my RadGridViews?  Am i missing anything? Can anyone help.

I couldn't to change TimeRulerMonthViewItem.


Code snippets   below :

 <Window.Resources>
            <Style x:Key="TimeRulerMonthViewItemStyle" TargetType="telerik:TimeRulerMonthViewItem">
            <Setter Property="telerik:StyleManager.Theme" Value="Windows8"/>
            <Setter Property="ContentTemplate">
                <Setter.Value>
                    <DataTemplate>
                        <TextBlock Text="WhyCantChanged"/>
                    </DataTemplate>
                </Setter.Value>
            </Setter>
     </Style>
        <telerik:OrientedTimeRulerItemStyleSelector x:Key="Origin" 
                                                 MonthViewTickStyle="{StaticResource TimeRulerMonthViewItemStyle}"/>
    </Window.Resources>
<Grid>
        <telerik:RadScheduleView x:Name="ScheduleView"
                                  telerik:StyleManager.Theme="Windows8" TimeRulerItemStyleSelector="{StaticResource Origin}">
            <telerik:RadScheduleView.Resources>
                <Style TargetType="telerik:RadButton">
                    <Setter Property="ContentTemplate">
                        <Setter.Value>
                            <DataTemplate>
                                <TextBlock Text="I am Mark."/>
                            </DataTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </telerik:RadScheduleView.Resources>
            <telerik:RadScheduleView.ViewDefinitions >
                <telerik:MonthViewDefinition/>
            </telerik:RadScheduleView.ViewDefinitions>
        </telerik:RadScheduleView>
    </Grid>

It could not change  Content. Do I just have to setting its ControlTemplate ,Only one way? Why not setting ContentTemplate?
