Hi,

after updating, I'm getting error when I try to change  AccentColor of metro theme. This is the error:

"Cannot set a property on object 'Telerik.Windows.Controls.MetroColorPalette' because it is in a read-only state."

Strange red colour border line is coming if I select a gridview.  Can somebody tell me how to remove this red color border line.

I am not able to get the scrolling working on RadPanes which are loaded using Prism's region manager onto a RadGroup.

Here is the main shell window which is hosting RadDock

<Grid>
   <telerik:RadDocking AllowUnsafeMode="True" Grid.Row="1"> 
            <telerik:RadDocking.DocumentHost>
                <telerik:RadSplitContainer>
                    <telerik:RadPaneGroup prism:RegionManager.RegionName="{x:Static CommonUI:Constants.RegionShellCenter}" />
                </telerik:RadSplitContainer>
            </telerik:RadDocking.DocumentHost>

       <telerik:RadSplitContainer InitialPosition="DockedRight" Width="600" >
                <telerik:RadPaneGroup prism:RegionManager.RegionName="{x:Static CommonUI:Constants.RegionShellRight}"/>
            </telerik:RadSplitContainer>
    </telerik:RadDocking>
  </Grid>

Here is my RadPane class that I load onto the above RadPaneGroup. This pane hosts a local usercontrol.

<telerik:RadPane x:Class="MyNamespace.ReservoirDataPane"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
             xmlns:prism="http://www.codeplex.com/prism"
             xmlns:local="clr-namespace:MyNamespace"
             Header="Reservoir">
     <local:ResPropControl/>
</telerik:RadPane>
 [Export]
    public partial class ReservoirDataPane : RadPane
    { }




I tried having Scroll around the RadPaneGroup and then inside RadPane around the local usercontrol. I also tried enabling it in the

Grid inside the usercontrol. None of this worked. Any help will be greatly appreciated. Thanks.

Hi,

Can we implement the spellChecker on Radbutton using Command binding? this there a sample implementation for this?

Hi, I embedded a RadRibbonView  in a RadRibbonWindow. I expected the Application Icon to look as in Img.1 




But I get it as below - icon before the tabs.



Can someone please suggest me what I should be doing to achieve the Round Shaped Application icon as in IMG 1 ?

Thanks,

I want to use RadGridView to display missing relations in a database using the Entity framework. I have defined several columns with path bindings to subtables. (eg. Table1.ID) When the datagrid is loading such a column with a 1 to 1 relation the entity framework throws an exception if the related row does not exist in the database, but the RadGridView does not display this error. (I tried several binding settings and manually added an ExceptionValidationRule and set the ValidateOnTargedUpdated = true, but the errors don't show up in the datagrid) The ultimate solution would be if I could display an error message like "Related row in Table XXX and ID 123 not found" in the tooltip of the grid cell.

The only way the error gets displayed is to write a validator which e.g. checks for null values and then to enter the cell edit mode. Then the error gets displayed. But I never got the entity framework exception to display in the datagrid.

Another approach is to write a DataTemplate for every column which triggers the Validation.HasError event. Using this method the errors get displayed when the column is bound, but this does also not work for entity framework exceptions and needs a lot of xaml code. What is the best solution to get a good error message without to write a lot of xaml code?

Hi,

I use a RadDataPager bound to a Linq2Sql table.
This works fine, but since I have a lot of data it takes about 2 seconds to change a page.

Here my Problem starts.
I want to indicate the loading by showing a busy indicator.

This works (without any coding) when I use async dataloading on the RadGridView.
But then a sort / filter breaks the application.
I found some other topic here that this is "normal".

I also tried to handle PageIndexChangeing and DataLoaded setting IsBusy on the Grid.
But it doesn't work (UI is not updated while loading).

So is there a way to achieve what I want since Async Loading is not an Option on the Grid.

Thanks
Manfred

I would like to bind a data trigger in a style trigger based on a row number. I need to suppress a value in a cell but only for the first row.

I'm not sure what property to bind to to get the row index or something similar.

Any help would be greatly appreciated.

Thanks,

John

Hi,

when I set my RadWindow WindowState property to Maximized, at startup, my RadWindow appear over my taskbar. Is it possible to have the same behavior as the standard Window class.

Thank's

I am not able to get the rows having all the columns. Only the columns which are visible using scrollbar are coming as cells of that row.

I have used below given code.

var rows = gridView.ChildrenOfType<GridViewRow>();

 

 

 

foreach (var row in rows)

 

{

 

 

foreach (var cell in row.Cells)

 

{

 

 

foreach (var selectedItem in gridView.SelectedItems)

 

 

 

{

 

 

 

var row = (gridView.ItemContainerGenerator.ContainerFromIndex(1) as GridViewRow);

 

 

 

 foreach (var cell in row.Cells)


Please suggest me how to get full row having all the columns from selected items.
I have enabled column & row virtulization.
