Hi,

The TimeLine items randomly positioned on the rows.

- Group 1
XXXXXXXXXXXX   O   O   O    O   O   O     O   O   O

         XXXXXXXXXXXX XXXXXXXXXXXX  

               
+ Group 2

Is it possible to choose a row item ? I must have a period followed by several events without duration on each row in the same group :

- Group 1
XXXXXXXXXXXX   O   O   O

         XXXXXXXXXXXX    O   O   O

                  XXXXXXXXXXXX   O  O  O

+ Group 2

 I have to GridViewDataColumns in a single grid.  Both have DataMemberBinding set. Both display the information in the grid however filtering does not work on the second one. The only difference betweend the two is one has a long Path than the other. Are there any known bugs with this and is there a work around?

This one works
   <telerik:GridViewDataColumn Width="75"
                                                    MinWidth="75"
                                                    DataMemberBinding="{Binding Path=PaymentSubTypeDetail.PurchaseBased}"
                                                    Header="%"
                                                    IsFilterable="True"
                                                    IsSortable="True" />

This one doesn't work
<telerik:GridViewDataColumn Width="*"
                                                    MinWidth="100"
                                                    DataMemberBinding="{Binding  Path=PaymentSubTypeDetail.ReceiptTicketStyle.Name}"                                                  
                                                    Header="Receipt Style"
                                                    IsFilterable="True"
                                                    IsSortable="True" / >
                       
               

I have an issue with highlighting an item when typing in the combobox. It's reproducible with the WPF Controls Examples like this:

- Open WPF Controls Examples
- All controls
- Select combobox demo
- In more ComboBox Examples select the Data Binding example
- Click on the top combobox (The not editable sample)
- Type PB
- The item 'PB knackebrod AB' should be highlighted, but it's not
- Press enter
- The tem 'PB knackebrod AB' is selected

So it does find the correct item, but does not highlight it.

Could you please fix this?

Hello,
I'm mainly using Summer theme as implicit styles. However I realized that System.Windows.xaml of this theme is causing exception in WPF designer on Visual Studio 2012. When I'm exclude these styles from resources everything is correct, after including I have crash again. I've started testing and realized that this is happening with summer theme but e.g. Windows8 is working without issue. I've checked office and it has the same issue. The issue is only with System.Windows.xaml  file. I tried to find where it is but I couldn't

There is other issue that I have which is related to .NET 4 and Visual Studio 2010:
in your implicit styles there can be found e.g. following clause:
Becaue I'm using Polish operating system designer (becuase of VS bug) cannot parse this (it doesn't like commas). Could you please change commas to spaces? Which is proper as well and you already using that in most places but not always. I can find examples where commas can be found. It is taking me a lot of time to upgrade project properly becuase I need to take care with this bug.

I couldn't able to apply rounded corners to the SubMenu's in the RadContextMenu. I do like to know how to set the minwidth for submenu just like in the TopLevelMenu and How to change the highlightcolor. Any help would be great. Thank you in advance.

Hi,
The problem:
  On the click of a row I have to show the child records (more suitable for HierarchicalTemplate but for some unknown reasons it failed in our project, though worked in the demo I prepared). Basically it seems that the row is not expanding to show rowDetailTemplate which contains another radgridview. The issue was due to some properties in style. I don't find a link to delete, please delete this link. I am facing another issue but will open an appropriate thread.

So I am using RowDetailsTemplate, which contains RadGridView  again. I have moved binding logic from the XAML file to code behind for testing in the OnRowDetailsVisibilityChanged. The problem is binding is working fine in all the cases, but detail grid shows exactly over the parent row. I am attaching the image. I have trying doing the same with GridViewToggleRowDetailsColumn but result is the same. Here is my grid Code and thanks in advance for the help.

<telerik:RadGridView  Name="gridCountEntry" MinHeight="500" 
   RowDetailsVisibilityChanged="GridCountEntry_OnRowDetailsVisibilityChanged" ItemsSource="{Binding CurrentRecord.StockTicketLines, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" ShowGroupPanel="False" AutoGenerateColumns="False" CanUserFreezeColumns="False" RowDetailsVisibilityMode="Collapsed" >

<telerik:RadGridView.Columns>

     <telerik:GridViewToggleRowDetailsColumn />

      </telerik:RadGridView.Columns>  
      <telerik:RadGridView.RowDetailsTemplate>
          <DataTemplate>
            <telerik:RadGridView ShowGroupPanel="False" AutoGenerateColumns="False" CanUserFreezeColumns="False" MinHeight="90" Margin="15,15,15,15">
          <telerik:RadGridView.Columns>
        <telerik:GridViewDataColumn DataMemberBinding="{Binding TransactionDate}" UniqueName="TransactionDate" Header="Trans Date" IsReadOnly="True" Width="70"/>
            <telerik:GridViewDataColumn DataMemberBinding="{Binding PerformedBy}" UniqueName="PerformedBy" Header="Who" IsReadOnly="True" Width="70"/>
              </telerik:RadGridView.Columns>
          </telerik:RadGridView>
          </DataTemplate>
        </telerik:RadGridView.RowDetailsTemplate>
    </telerik:RadGridView>

Any progress? In a post you where writing this.

Hi Branko,

Currently RadPropertyGrid does not support DataErrors validation (It supports exception validation only). However, as it is not a major feature we can implement it for you and include it in an internal build. I believe that we will manage to introduce this change in two weeks. I will keep in touch with you, in order to notify you as soon as the mentioned IB is available for download.

Hello.

I'm using the RadTabControl with the Expression_DarkTheme.  I want to change the background of the tab headers when selected.  Is there a relatively simple way to do this  or do I have to re-template the whole tab header?

Thanks in advance.

I am using MVVM pattern.  I have a RadGridView and have bound the ItemsSource to a collection and SelectedItem to an individual item in the VM.    This works, and I have some buttons to reorder the collection.  They call a command on the VM that moves the SelectedItem up or down in the collection.  This works fine but it appears that after the item gets moved, the SelectedItem becomes null.  My goal is to be able to select an item in the RadGridView and then click the "Move Up" button several times to move the item up in the collection.  Currently the experienced behavior is that I click the item and get one Move Up(or Down) before the SelectedItem becomes null and I am required to select an item to continue moving items.  I have put debug statements in both the SelectionChanged and SelectionChanging events on the RadGridView. 

Upon running my app, here is the order I see:

Event	SelectedItem
SelectionChanging	null
SelectionChanged	CorrectItem
Move method	CorrectItem
SelectionChanging	CorrectItem
SelectionChanged	null

I even tried manually setting the SelectedItem in the VM after reordering it, but the reset to null appears to happen sometime after this. 
I have the latest version (2013.1.220.45)  installed and referenced in my project.
   Please let me know if something is unclear.

Thanks,
Chris
