Is it possible to show DataAnnotation validation error on property not shown on the GridView? Maybe at the row level.  I want to show that the selected item cannot be deleted.

I like the sample Menu Customization in with reference WPF Demo however the sample focus only on the display. How would I got about adding Command binding to this sample?  

If I add a Command property of type ICommand to your MenuItemViewModel and can't bind to the newly added property since the MenuItemViewModel is not a Dependency object.  

Any suggestion?

Hello,

I have programmatically added one table in another:


The outer table cells have red borders and inner table cells have gray borders (see attached image).

After the inner table there is a vertical space.
How to remove this space ?

Thanks

I've noticed that the SDKSamples directory is no longer in the WPF source code drop as of the 2013 Q1 release.  Has that been moved to a separate download?  For some reason, I'm not seeing it anywhere..

Thanks, Dan

I created custom RadDataFilter , which contains dropdown list. DropDown List is OK. Now here is new requirement, I want to add telerik DateTimePicker.  DateTimePicker Bind successfully, problem is that I can’t get selected date value. Therefore FilterDesripter.value is not set.

For Combobox here is template

<DataTemplate x:Key="ComboBoxEditor">

            <telerik:RadComboBox  SelectedValue="{Binding Value, Mode=TwoWay, FallbackValue=null}"    MinWidth="100" />

        </DataTemplate>

 

But how I’ll set selectedDate Value, here is my Code.

 <DataTemplate x:Key="DateTimeEditor">

      < telerik:DatePicker MinWidth="100" SelectedDate="{Binding Value}"></my:DatePicker>

 </DataTemplate>

Hello,
      I use ComboBox disabled to display the data, and I want to change the appearance of ComboBox disabled, which make it look like a TextBox disabled.  Could you give me any solution to achieve the feature?

Thanks & Best Regards

Hey,

I'm using and GanttView and looking for a way to use the available space dynamically. At the moment you can specify how much time is displayed and scale the time per pixel ratio (PixelLength). It would be nice to have a way of setting time/pixel to auto, so that it displays the whole visible range in the timeline part of the control.

At the moment I could only get this working by doing some kind of calculation. I need to get the RenderSize of the whole control subtract the fixed columns width to get the remaining space. Finally I have to divide VisibleRange's ticks by this number, to get the scaling right. This is not that heavy calculation but it would be cool if you could add that possibility to the component. Especially as you are forced to fix the column's size! I think there is more than one person, who would like that to be implemented.

Thank you in advance.

Best regards,
Peter Schmidt

How do I convert the following xaml in code:

<telerik:GridViewDataColumn.CellStyleSelector>
                        <telerik:ConditionalStyleSelector>
                            <telerik:StyleRule Condition="UnitPrice > 10">
                                <Style TargetType="telerik:GridViewCell"
                                       BasedOn="{StaticResource GridViewCellStyle}">
                                    <Setter Property="Background"
                                            Value="{StaticResource AccentBrush}" />
                                    <Setter Property="Foreground"
                                            Value="{StaticResource MainBrush}" />
                                </Style>
                            </telerik:StyleRule>
                            <telerik:StyleRule Condition="UnitPrice &lt;= 10">
                                <Style TargetType="telerik:GridViewCell"
                                       BasedOn="{StaticResource GridViewCellStyle}" />
                            </telerik:StyleRule>
                        </telerik:ConditionalStyleSelector>
                    </telerik:GridViewDataColumn.CellStyleSelector>

I'm using the MVVM pattern such that I've got a comboboxColumn bound to a datasource.

My intention was whatever the user select, it should update the description of another column. At the moment it is not updating. The underlying data has changed but not refreshed.

What am I missing?

What I'd like to achieve is like these two image attachments which were created in Excel. I'd like to have two levels of X-Axis labelling. I'd also like to have clustered and stacked.

Is this possible with the Telerik WPF charting tools?
