ShowGroupPanel=False in child grid

[Orit]

Hey

How can I set ShowGroupPanel=False
in a child grid (when I use hirarchy)

Thanks

[Orit]

I solved this problem
but now I have another question,
how can I control the columns of the child grid
change their header text etc.
Thanks.


by the way, this is what I used to solve my problem
 <telerik:RadGridView.HierarchyChildTemplate>  

<DataTemplate>

<telerik:GridViewDataControl IsFilteringAllowed="False" ShowGroupPanel="False"/>  

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

Hello Orit,

This is done in exactly the same way as you would do it for a normal top-level grid. In other words, if you want to configure the columns, simply add a RadGridView.Columns tag inside the child grid and do the work there. Here is a sample code snippet demonstrating that:

<Window x:Class="ManualHierarchy.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
    xmlns:local="clr-namespace:ManualHierarchy"
    Title="Window1" Height="300" Width="300">
    <Grid>
        <telerik:RadGridView
            x:Name="grid"
            IsReadOnly="True"
            AutoGenerateColumns="False"
            ColumnsWidthMode="Fill">

            <telerik:RadGridView.Columns>
                <telerik:GridViewDataColumn HeaderText="First Name" DataMemberBinding="{Binding FirstName}" />
                <telerik:GridViewDataColumn HeaderText="Family Name" DataMemberBinding="{Binding LastName}" />
            </telerik:RadGridView.Columns>

            <telerik:GridViewDataControl.HierarchyChildTemplate>
                <DataTemplate>
                    <StackPanel DataContext="{x:Null}">
                        <telerik:RadGridView
                            CanUserReorderColumns="False"
                            CanUserFreezeColumns="False"
                            ShowGroupPanel="False"
                            ColumnsWidthMode="Auto"
                            ItemsSource="{Binding Instruments}"
                            Loaded="RadGridView_Loaded">
                            <telerik:RadGridView.Columns>
                                <telerik:GridViewComboBoxColumn
                                    HeaderText="Instruments Played"
                                    DataMemberBinding="{Binding Path=.}"
                                    ItemsSource="{Binding Source={local:EnumValues {x:Type local:Instrument}}}"/>
                            </telerik:RadGridView.Columns>
                        </telerik:RadGridView>
                    </StackPanel>
                </DataTemplate>
            </telerik:GridViewDataControl.HierarchyChildTemplate>
        </telerik:RadGridView>
    </Grid>
</Window>

I have attached the sample project that the above code snippet is from. Please, take a look at it and let me know if you have any other questions.

Thank you for your answer
in this way I managed to add my specific columns
but now I dont see the values in them

what I'm tring to do is,
I hava a dataset with two tables- parent and child
and I want to show them hierachicly
(I have to set their header text by myself !)
if there is a better way to do this, I will be happy to get the code

thanks

Hello Orit,

This is my mistake, please accept my apologies. I have sent you XAML that is not entirely correct.

Please, remove the StackPanel's DataContext setting to null from the XAML. It should look like this:

            <telerik:RadGridView.HierarchyChildTemplate>
                <DataTemplate>
                    <StackPanel>
                        <telerik:RadGridView CanUserReorderColumns="False"
                                CanUserFreezeColumns="False" ShowGroupPanel="False"
                                ColumnsWidthMode="Auto" ItemsSource="{Binding Path=Details}">
                            <telerik:RadGridView.Columns>
                                <telerik:GridViewDataColumn UniqueName="RequestNumber"
                                        HeaderText="מספר דרישה" Width="Auto"/>
                                <telerik:GridViewDataColumn UniqueName="Text" HeaderText="תאור"
                                        Width="Auto" />
                            </telerik:RadGridView.Columns>
                        </telerik:RadGridView>
                    </StackPanel>
                </DataTemplate>
            </telerik:RadGridView.HierarchyChildTemplate>

I am attaching the modified source code. Once again, please excuse me for the inconvenience.

Drop me a line, if there are other problems.

Hi Ross
Thanks fot your reply.

I used your code,
I can see that it changes the properties of the all child grid
like 

IsFilteringAllowed="False"
ShowGroupPanel="False" etc.

but there is no change in the columns
not on the headerText, nothing
it shows the two columns that I have in the dataTable
even if I drop them from the   

RadGridView.Columns

any idea??

Hello Orit,

Now I see what you mean. Sorry for the misunderstanding.

Unfortunately, the scenario that you are describing is currently not available out of the box. However, we have gone the extra mile and "hacked" the grid to achieve the scenario that you are describing. Have in mind that what we have done is not very intuitive and this is not the way things should be done in general. Hopefully the new Q2 release will introduce an entirely new data engine and all of the "hacks" we have done will not be necessary anymore.

I have attached the modified project and placed code comments to explain what we have done. Please, let us know if you don't understand something or if you would like to ask us something else.

Ross
