flat hierarchy style on childtable of a gridview

Hello out there

I'm just working on a report table, which should list my materials and all materials below one.
To display the data, I'm using the gridview with the childtemplate things.
This is working without problems but I want to use a flat hierarchy style instead of the default one.
So it should look like this

Cost Type
Parent x x
Child x x
Child-child x x

I really don't know how to do this.
Hope you can help me.

Thanks in advance!
Greetings
Emanuel

GridView

Hi,

i found this example to change the CellTemplate. This works fine, but how do i insert a "Passwordbox"?

<telerik:RadGridView x:Name="RadGridView" AutoGenerateColumns="False" >

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}" Header="Select hobby" />

<telerik:GridViewDataColumn >

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate>

<telerik:RadComboBox ItemsSource="{Binding AvailableHobbies}" >

<telerik:RadComboBox.SelectionBoxTemplate>

<DataTemplate>

<TextBlock Text="{Binding Owner.Choices}" />

</DataTemplate>

</telerik:RadComboBox.SelectionBoxTemplate>

<telerik:RadComboBox.ItemTemplate>

<DataTemplate>

<StackPanel Orientation="Horizontal">

<CheckBox IsChecked="{Binding IsChecked, Mode=TwoWay}"

Content="{Binding Description}" />

</StackPanel>

</DataTemplate>

</telerik:RadComboBox.ItemTemplate>

</telerik:RadComboBox>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

<telerik:GridViewDataColumn DataMemberBinding="{Binding Choices}" />

</telerik:RadGridView.Columns>

</telerik:RadGridView>

With Passwordbox:

<DataTemplate>

<StackPanel Orientation="Horizontal">

<Passwordox Name="Password_txt" Password="{Binding Password}" />

</StackPanel>

</DataTemplate>

binding does not work, but why? A simple Textbox ist working fine with this Binding!
Thanks Best Regards
Rene

Making Individual Shapes Read-Only

How would one go about making certain shapes in a diagram read-only--i.e. cannot be resized, or manipulated in any way--but would still be enabled (i.e. HitTest is enabled)? The IsManipulationEnabled property on the shape seems to have no impact.

Column Background overrides Row Highlight

When I specify the Background color of a column, the Row Highlight no longer highlights that column.

<telerik:GridViewDataColumn Width="10*" Header="Enabled?" Background="White" DataMemberBinding="{Binding IsEnabled, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" UniqueName="IsEnabled" IsReadOnly="False"/>

How do I change the background color for a particular column without it interrupting the Row Highlight?

Shift-Tab not working

When I have an item selected in a RadTreeView, pressing the Tab key seems to work appropriately (shift focus to next focusable element), but Shift-Tab doesn't appear to be working at all. Is this a known issue?

RadPanes get stuck on MouseOver

Hi,

I am encountering the following crash scenario:

1.) Unpin all RadPanes in the application.
2.) While pressing the left MouseButton - hover over the AutoHide-Items up and down quickly.
3.) --> The RadPanes slide in and out forever and the UI gets stuck.

Is there a solution to this behaviour?

Thanks,
Ruth S.

HierarchyChildTemplate - Tabbing Sequence

We're having problems trying to get the tabing sequence working correctly for a WPF RadGridView with a HierarchyChildTemplate per row. With grid rows fully expanded the grid only tabs through all row cells and never tabs into the row’s child template. Can you please advise how we can solve this issue.
