Hi

I need a hint how to implement the editing of multiple cells with one operation? Using MS-DataGrid I'm waiting in the PreviewKeyDown event for Key.Enter and then copy the entered value from the visual tree to all selected cells.

Is there an easier way to do this with the RadGridView?

UPDATE: Found the RowEditEnded by my self. The only left issue was to leave the edit mode of the next cell after hitting enter. Solved this in the PreviewKeyUp event.

My WPF question/problem is similar to the already answered question in this thread for WinForms: http://www.telerik.com/community/forums/winforms/gridview/scroll-bar-position-after-refreshing-grid.aspx

The problem is I don't have a way to get the Grid or Scrollbar controls/elements in the code behind because we are using a strict MVVM approach so this solution does not fix the problem I am having in WPF.

If there are any other tips or tricks you all might have that would work for MVVM, it would be much appreciated. This is one of the last problems we are having with a couple of our windows with large sets of data in a RadGridView. While the user is viewing data
in the Grid, I want the Grid to continue updating AND preserve the scrollbars position within the Grid -- instead of the scrollbars position returning to the top of the Grid. Thanks in advance for any help or guidance!

My grid is displaying aggregate results in the group headers which I want to remove; I only wish to display the aggregates in the column footers.  My WPF form uses the following;


My problem is that it appears to be ignoring the style in Windows.Resources and displays the aggregated data in the group headers.

  

I have a RadPaneGroup and RadTreeview, I compare a RadTreeViewItem Header Header with the RadPane Header and close the RadPane when RadTreeViewItem is selected. How do I?

TreeView
<telerik:RadTreeView  x:Name="tvConfiguracao" IsOptionElementsEnabled="True" Checked="tvConfiguracao_Checked"
      <telerik:RadTreeViewItem x:Name="tviVenda" Header="VENDA" />
      <telerik:RadTreeViewItem x:Name="tviCompra"  Header="COMPRA />                
</telerik:RadTreeView>
Panels
<telerik:RadDocking x:Name="rdPrincipal"                             
            <telerik:RadSplitContainer InitialPosition="DockedBottom">
                <telerik:RadPaneGroup x:Name="rpgFiltros"
                    <telerik:RadPane x:Name="RadPaneCompra" Header="COMPRA"> </telerik:RadPane>
                    <telerik:RadPane x:Name="RadPaneVenda" Header="Venda"> </telerik:RadPane>
                </telerik:RadPaneGroup>
            </telerik:RadSplitContainer>
</telerik:RadDocking>
Event
private void tvConfiguracao_Checked(object sender, Telerik.Windows.RadRoutedEventArgs e)
       {
           var item = rdPrincipal.Panes.FirstOrDefault(i => i.Header == e.Source.Cast<RadTreeViewItem>().Header);
  
           if (item != null)
               item.Cast<RadPane>().IsHidden = true;
       }
Finds no Pane Even with Header, what is wrong?

Hi, 

I am following some examples to bind a CartesianChart to a Datatable but I haven't been able to do it, this is my code:


And the code behind:




And when I run the application, the series do not appear.

I am missing something?

Thanks,

Hello!

My radGridView is filled by numbers. I export it to excel.  All cells in this file has type 'Common'.
This cause some values look rounded. 
For example: real number is 113199997.01, but in excel it looks like '113199997'.

How can I force cell to be 'Numeric' type?

Hi,
is it possible to hide the property grid row header (the first column, the one with the selection arrow)?

Thank you very much!

Hi,

we are doing standard validation using WPF INotifyDataErrorInfo and IDataErrorInfo interfaces on row values.
The validation messages display correctly, however are always duplicated (see attached pic). 

The column definition looks like this:

Any idea why this could be happening?

Note that the INotifyDataErrorInfo GetErrors() is only returning one item for the column

Regards,
Stevo

 

 

 

 

 

Hello!

On my RadPropertyGrid (having AutoGeneratePropertyDefinitions="True") I need to be able to show a context menu having a Reset 
menu item that will set the default value for the specific property definition selected.

To make things more complicated I cannot even see a simple ContextMenu for the entire property grid:

I tried to add a context menu to the whole RadPropertyGrid


But I cannot see that at all because the property grid is contained in the SettingsPaneView of a RadDiagram and no matter where in make the right click inside the PropertyGrid - I get the diagram's context menu

I badly need help!

Hello everyone,

We are encountering a little issue with spellchecking function of the richtextbox.

Let me explain the context : we are using Framework 3.5 and the runtime version of the Telerik library is v2.0.50727 for WPF.
Why 3.5? Because we also use Sharepoint 2010 and we have an application working with MVVM design pattern.

So here is our problem : we have a wpf page that creates dynamicly a table (rows and columns are dynamics) with a RichtextBox and each cell. Each cell has the right text and works fine. But whenever we try to use the spellcheck, it doesn't work. We investigated and realised that even if the spellcheck would see the wrong words on the control, you can't change it from the Right click context menu. We then realised that when we open up the context spell checking window, it automatically select the content of the first richtextbox object we have on the page. So even if the text content is the right one, it tries to replace it from the first RichtextBox of the table. Same goes for the Copy and paste functions.

First, we are not using the Telerik rich textbox by itself, we have another control that herits from it :

Here is the control that is used for our table :

Here is the GridView table we use :

And last but not least, this how we get our DataTemplate for each column :

Thanks in advance !
