We are having a problem with the GridView filter when a customers screen resolution is set smaller. When clicking the header to open the filter, the filter box is partially hidden behind the grid. 

I have attached a screenshot of the full screen of our app on a small resolution. 

Hi Experts,

I have a question about GridViewColumnGroup. Here is my code below:

<telerik:RadGridView GridLinesVisibility="Vertical"  CanUserFreezeColumns="False" DataContext="{Binding ElementName=mainWindow}" ItemsSource="{Binding As}"
        AutoGenerateColumns="False"
        IsFilteringAllowed="False"
                             ShowGroupPanel="False"
        RowIndicatorVisibility="Collapsed">
            <telerik:RadGridView.ColumnGroups>
                <telerik:GridViewColumnGroup Name="Age" Header="Age" />
                <telerik:GridViewColumnGroup  Name="TestCode" Header="TestCode"/>
            </telerik:RadGridView.ColumnGroups>
            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn  DataMemberBinding="{Binding Min}" ColumnGroupName="Age"/>
                <telerik:GridViewDataColumn  DataMemberBinding="{Binding Max}" ColumnGroupName="Age" />
                <telerik:GridViewDataColumn  DataMemberBinding="{Binding TestCode}" Width="120"/>
            </telerik:RadGridView.Columns>
        </telerik:RadGridView>

You can see that the Age column is separate into "Min" and "Max" Column now. It is what I want. But how to merge the TestCode column header into one row? And how to center the "Age" header?

Any comments and suggestion is appreciate. Thanks.

Tile View when maximized the minimized tile windows are not shrinking resulting in lossing the data. Setting RowHeight and Column Width for minimized windows works fine but i need to have a consistent look with standard height and width. How can i acheive that.

I am using the ScheduleView and am looking to add a vertical line to represent the current time

I overrode the OrientedTimeRulerItemStyleSelector and am able to change the color of the TimeRulerLine

However, I want the current line to be above the schedule appointments. Is there a way I can set the Z-index of the TimeRuleLine?

Thanks

Using the 2013.2.724.45 version:

When using the RadMaskedTextInput, if the user types a space very quickly after typing a letter, the previous letter is removed, but the caret position still advances.  I have reproduced this bug in the WPF Rad Controls Demo Q2 2013 SP1 for MaskedTextInput.  

When typing slowly, the bug will not appear.  I could not reproduce the bug in the SL demo on the web.

It does not seem to matter what settings are made on the control.

Please advise.  Thanks!

Hi,

How do i add this second Group?  First Group is Speakers and works great, but what is to do to add the second Group "Abteilung"?

thanks

Hi,

I have RadRichTextbox with XamlDataProvider and I use Mail Merge function.  In UI it works great.  But when I try to extract a current document on the backend (eg.  RadDocument resultDoc = myRadRichTextBox.Document.MailMergeCurrentRecord();) the resultDoc is empty.  If I do not use XamlDataProvider then it works fine. 

Am I supposed to be extracting merged document differently when I use DataProvider?

Some background ...  I am creating an email editor for mail merge.  Email text is saved in the database.  I binded XamlDataProvider's Xaml property to property on ViewModel.  This way I can save and load it to and from database.  User uses Mail Merge function to scroll through records,.  Then user can click on a Button which should send email with the current record being viewed.  So I need to extract the document. 

Thank you in advance.
