Dear team,

I have a customized column that constains my own usercontrol inside. The column works perfectly but when we sort by another column, this column don't move. 

This is my column definition:

<telerik:GridViewDataColumn                                    
                                    Width="*"
                                    Header="{Binding Source={StaticResource appResx}, Path=ep_ClearOpeningRange}"
                                    HeaderTextAlignment="Center"
                                    IsReadOnly="False">
                                    <telerik:GridViewDataColumn.CellTemplate>
                                        <DataTemplate>
                                            <StackPanel>
                                                <TextBox Text="{Binding ModelOpeningSill.OpeningType.ProductAttributeValueCode}" />
                                                <my:MultiRangeSlider                                                    
                                                    Id="{Binding ApplicationRangeId}"
                                                    Maximum="3000"
                                                    Minimum="600"
                                                    PropertyChangedCommand="{Binding DataContext.ApplicationRangeChangedCommand, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type local:ModelDetailView}}}"
                                                    Thumb1="{Binding CertifiedMinimumClearOpening, Mode=TwoWay}"
                                                    Thumb2="{Binding CertifiedMaximumClearOpening, Mode=TwoWay}"
                                                    Thumb3="{Binding RecommendedMinimumClearOpening, Mode=TwoWay}"
                                                    Thumb4="{Binding RecommendedMaximumClearOpening, Mode=TwoWay}"
                                                    TickFrequency="50" />
                                            </StackPanel>
                                        </DataTemplate>
                                    </telerik:GridViewDataColumn.CellTemplate>
                                </telerik:GridViewDataColumn>

My usercontrol is a multirange slider called: <my:MultiRangeSlider>. The textbox inside the StackPanel is sorted correctly but my usercontrol is totally static.

Attached captions maybe can help to understand my problem. In these captions the textbox inside the stackpanel was hidden (only was created for test).

Thanks in advance!

Hi,

My child nodes seem to have a "mystery" column in front of the actual item, and you can only see it if you click on it. If you click on it, the items itself de-selects, and the "mystery column" in front of it becomes active for that row. How do I blend/merge/remove the blank column in front of all my child node rows ?

Thanks,

Barry

Hide expansion arrows on rows with no children ?

I have indented child rows that have no children under them, but still have the arrows - they expand into nothing.

How can I hide them ?

Thanks,

Hi,

we have multiple problems with the performance of the GridView. I have a simple project to demonstrate the problems, but I cannot upload it. Is there any way to do this?

In our application we do not know all the columns at design time, so we have to create the columns at runtime in the code behind.

First performance issue is, after starting the application, if you resize the window, it takes too much time, so you see black parts in the window on resizing.

Next issue was the scrolling. This is acceptable in the sample project, where we set a fixed length and didn't put the grid in a stackpanel or grid, but in our application the grid will be in a docking window and then there is also a poor performance when scrolling.

Next thing is filtering and sorting. It takes about 3 seconds, thats too much.

Are we doing anything wrong with the GridView? We would appreciate any help.

We already read the performance tips and tricks, but it didn't help much.

Best regards

Hi,

I have a DocumentHost with a couple of DocumentPanes. When I drag a pane out it becomes a tool window. I want the tool window to have that documentpane inside it when in floating state (Example: Visual Studio). This is achievable in WinForms (Pic attached). Please guide me if it can be achieved in WPF as well.
