I am developing an application and I used LayoutControl , I noticed that the window persist in memory when I close it  , even if I use GC.Collect() to wake up garbage collector, there is a memory leaks concerning LayoutControl.  

Otherwise, if I put any other telerik component like RadGridView or RadMenu the window object is removed from the memory after closing .

Please help because I use  LayoutControl in 120 interfaces.

I use ANTS Memory Profiler 8 , Telerik UI for WPF R3 2017 SP1 , win7 sp1 x64 , visual studio 2013.

Hello

I need change some PropertyDefinition's IsEnabled on run time,my solution is change PropertyDefinition's IsReadonly
public virtual void SetEnabled() 
{
            var squidProperties = this.FindChildByType<RadPropertyGrid>() as RadPropertyGrid;
            if (squidProperties == null)
                return;
            foreach (var item in squidProperties.PropertyDefinitions)
            {
                item.IsReadOnly = !_enable;
                if (item.HasNestedProperties) 
                {
                    foreach (var subItem in item.NestedProperties) 
                    {
                        subItem.IsReadOnly = !_enable;
                    }
                }
            }
  }

when the PropertyDefinition has  EditorTemplate, when  the EditorTemplate is single control  as the following code  it is works right

<telerik:PropertyDefinition.EditorTemplate>
              <DataTemplate>    
                         <telerik:RadWatermarkTextBox 
                                                             IsReadOnly="{Binding IsReadOnly, RelativeSource={RelativeSource AncestorType=telerik:PropertyGridField}}"
                                                             Text="{Binding Filter}" />                                
                 </DataTemplate>
</telerik:PropertyDefinition.EditorTemplate>

but  when the EditorTemplate is nested controls  as the following code,  it is works wrong

   <telerik:PropertyDefinition.EditorTemplate>
                        <DataTemplate>
                            <Grid>
                                <Grid.ColumnDefinitions>
                                    <ColumnDefinition Width="*" />
                                    <ColumnDefinition Width="auto" />
                                </Grid.ColumnDefinitions>
                                <telerik:RadWatermarkTextBox Grid.Column="0"
                                                             IsReadOnly="{Binding IsReadOnly, RelativeSource={RelativeSource AncestorType=telerik:PropertyGridField}}"
                                                             Text="{Binding Filter}" />
                                <telerik:RadButton  />
                            </Grid>
                        </DataTemplate>
</telerik:PropertyDefinition.EditorTemplate>

the RadWatermarkTextBox status is not readonly, when set the PropertyDefinition isreadonly true 

what is the reason for this?

Hello,

I have been digging through the documentation and I am unable to find any information on the ability to include the header/row values when copying the cells from a pivot grid.  The actual values copy in to excel just fine, but I would like to include the header/row values.

Would someone be able to point me in the right direction?  Thank you.

Hey guys,

since i dont get it to work since 3 hours now i registered here in the hope you have a solution.

I have a GridView in my View:

The GridView Itemssource is bound to a DataView Property in my ViewModel.

The DataView is simply the .DefaultView of the Datatable i want to display.

With the data in my datatable i did some validation. In my validation i receive information which cells are invalid (rownumber and columnnumber/columnname).

Now my target is to set the style for the cells that are invalid (foreground color to red). But i cant get it working to get the GridViewCell based on the infos if have.

In some forum posts i saw code like MyGridView.Rows(index).Cells(anotherIndex) but the RadGridView dont have an accessable Row property for me.

I also tried some other things to get the cell like to get access the .Items Property or some attempts with the .ChildrenOfType<> method but nothing worked for me.

Is there any way to set the Cell-Style for a specific cell when bound to a DataTable or DataView? I cant use a cellstyle selector cause its not the value of the cell itself that is invalid, its only invalid in the context of row and column. The same value can be valid in another row or in another column.

You guys have any ideas?

Could i mark the DataView Cell in any way that i could react from a cellstyle selector on it or something like that?

Sirs,

I'm using RadVirtualGrid with a Custom DataProvider and I would like to format its columns where some columns would fit their width to their content, others to their cells' content, some columns would have their cells aligned to left, others to right, and so on.

I mean I want to apply a different style to each column in my RadVirtualGrid, however I don't know how to handle these styles.

Thanks in advance,
