Hi ,

I am not able to inherit/override style for telrik:GridViewHeaderCell

 I have Common ResourceDictionary  Style.Xaml , it has

<ResourceDictionary xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation">
    <Style TargetType="telerik:GridViewHeaderCell">
        <Setter Property="FontWeight" Value="ExtraLight" />
        <Setter Property="FontStyle" Value="Normal" />
    </Style>
</ResourceDictionary>

Im MyControl.Xaml I have

  <Window.Resources>
        <Style x:Key="CheckBoxHeaderCellStyle"  TargetType="telerik:GridViewHeaderCell">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="telerik:GridViewHeaderCell">
                        <CheckBox HorizontalAlignment="Center" VerticalAlignment="Center"/>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </Window.Resources>
    
In code behind I am using

 var dict = new ResourceDictionary
                           {
                               Source = new Uri("MyApp;component/View/styles.xaml", UriKind.Relative)
                           };
Resources.MergedDictionaries.Add(dict);

I apply style in GridDataColumn as

<telerik:GridViewDataColumn HeaderCellStyle="{StaticResource CheckBoxHeaderCellStyle}"/>

In design mode I can see the checkbox in Grid Header.But It does not show a check box in GridHeader.

I'm setting the grid's datacontext to a dataset with just 100 rows (and 67 columns).

Quite frankly, the gridview's *vertical* scrolling performance sucks - big time. It seems the more columns we have, the worse it gets.  "Deferred" scrolling is not an option (it lags too, BTW).  We need the grid to scroll smoothly as the scroller is dragging down the scrollbar. 

Curiously, horizontal scrolling seems to work just fine, regardless of the number of columns we have in the dataset.

What can we/you do to improve this?

Is there a way to move the position of a tooltip form the default?  Currently, it is displaying bellow the mouse and that is causing it to go beyond the browser window and cuts it off.  I would like it to show above and to the right of the mouse position.  Thanks.

Hello

I tried putting  the 2009q2 dlls in the GAC and got the following error for the
"Telerik.Windows.Controls.Scheduler.Design.dll":

Assembly 'Telerik.Windows.Controls.Scheduler.Design.dll' is required to be strongly named.

Hi,

I was wondering whether RadControls for WPF support UI Automation...

So I created very simple WPF application: I dragged four Rad controls on a form (RadDatePicker, RadTimePicker, RadMaskedTextBox and RadNumericUpDown). Then I assigned AutomationProperties.AutomationId for each of Rad controls (for RadDatePicker it was "datePicker", for RadTimePicker "timePicker", for RadMaskedTextBox "maskedTextBox" and for RadNumericUpDown "numUpDown").

Now in c# (in Program.cs to be precise) I written code like this (mainWindow is a AutomationElement which represents main application window):

FindFirst method does not find anything, however It should if RadControls for WPF would support UI Automation. Out of four controls I've tested only RadNumericUpDown was found this way.

I've also checked my test application window using UISpy - only RadNumericUpDown had AutomationId properly assigned.

So my question are: 

Am I doing something wrong?

If no, when will RadControls for WPF fully support UI Automation?

RadControls for WPF version used in sample application: 2009.2.701.35

Thanks for help

I use the chart to display some data, but the labels can become very long.
Now I want to use the Default LabelFormat but I do not seem to get it work

I use the following      #LABEL{[a-zA-Z]{0,10}...}

But my string always stays as long as it is. I want the string to be a max of 15 chars and if longer have the tree dots after it

I'm adding items to a treeview programmatically and have set the tag property to a unique value.  How can I loop the items and when I come to my value select the item and then exit the loop.  I'm using

 

For Each item As RadTreeViewItem In RadTreeView1.Items

 

 

If CInt(item.Tag) = 3 Then

 

item.IsSelected =

True

 

 

Exit For

 

 

End If

 

 

Next

However I need to get the child items to the first treeview item

Thanks

 

I need to get the value of the selectedItem NumeroIncidencia column, I looked at the examples and following the steps that detail does not work, I can help.

Thank you.

 

A simulation code to see what I'm doing

<Grid>

<Button Height="36" HorizontalAlignment="Right" Margin="0,11,177,0" Name="cmdBuscar" VerticalAlignment="Top" Width="36">

<Image Source="iconos/buscar.gif" Name="Image5" />

</Button>

<ListBox Height="100" Margin="0,40,245,0" Name="ListBox1" DisplayMemberPath="NumeroIncidencia" VerticalAlignment="Top" />

<telerik:RadGridView x:Name="BuscarGrid" Margin="0,160,0,0" AutoGenerateColumns="False">

<telerik:RadGridView.Columns >

<telerik:GridViewDataColumn IsReadOnly="True" Header="Numero Incidencia" UniqueName="NumeroIncidencia" Width="150"/>

<telerik:GridViewDataColumn IsReadOnly="True" Header="Procedencia" UniqueName="DescripcionProcedencia" Width="120"/>

<telerik:GridViewDataColumn IsReadOnly="True" Header="Observaciones" UniqueName="Observaciones" Width="300"/>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</Grid>

Private Sub cmdBuscar_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles cmdBuscar.Click

Dim rd As New ReturnData.ReturnDataSoapClient

Dim ds As DataSet

ds = rd.ReturnDataset("SELECT NumeroIncidencia, DescripcionProcedencia,  Observaciones FROM Incidencias")

Me.BuscarGrid.ItemsSource = ds.Tables(0)

Me.ListBox1.ItemsSource = Me.BuscarGrid.SelectedItems

End Sub

I have no ListBox1 in the desired value

 

 

 

 Resolved.

I can display the data how I want it with my custom column headers and such. However, I have some columns in my child tables I'd like to have aggregates on and display in a footer in the child table. Can this be done?

Thanks,
Byron
