Hi,

I am looking to implement a three level hierarchy whereby the child grids are determined on the run time. For example if we select an option from a combo box present on the parent grid, it will create a child grid. Similarly we could repeat the same scenario for the child grid as well. I am looking into doing this by creating hierarchical templates for both the parent and the child:

<telerik:RadGridView x:Name="rgvData" CanUserFreezeColumns="False" GridLinesVisibility="Horizontal" ItemsSource="" IsReadOnly="True" AutoGenerateColumns="False">

<telerik:RadGridView.ChildTableDefinitions>

<telerik:GridViewTableDefinition />

</telerik:RadGridView.ChildTableDefinitions>

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding OrderDate}" Header="Order Date" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding EmployeeID}" Header="Employee" />

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

<telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCountry}" Header="Ship Country" />

<telerik:GridViewDataColumn DataMemberBinding="{Binding ShipCity}" Header="Ship City" />

</telerik:RadGridView.Columns>

<telerik:RadGridView.HierarchyChildTemplate>

<DataTemplate>

<telerik:RadGridView x:Name="RadGridView1" CanUserFreezeColumns="False" AutoGenerateColumns="False" ShowGroupPanel="False" IsReadOnly="True">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn DataMemberBinding="{Binding CustomerID}" Header="Customer ID" />

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

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

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

</telerik:RadGridView.Columns>

</telerik:RadGridView>

</DataTemplate>

</telerik:RadGridView.HierarchyChildTemplate>

</telerik:RadGridView>

// The Child will host another template that will define it's own child.

What would be the best way to tackle this scenario. Should I just go by creating the grids through code behind? I would like to stick to xaml. Any pointers would help me decide !

Thanks,
Farhan

Clear selection with keyboard?

The RadComboBox has a "clear selection button" enabling the user to clear the selection of the combobox. Is it possible to do the same thing with the keyboard or do I have to implement that myself?

Cannot select all rows with Ctrl+A

2010 Q3 SP1
Windows 7

With SelectionMode="Extended", pressing Ctrl+A does not select all items. The documentation claims it should (http://www.telerik.com/help/wpf/gridview-multiple-selection.html). The relevant part of the grid declaration is below.

            <telerik:RadGridView
                              ScrollViewer.CanContentScroll="True"
                              IsReadOnly="True"
                              ShowGroupPanel="False"
                              SelectionMode="Extended"
                              IsFilteringAllowed="True"
                              RowIndicatorVisibility="Collapsed"
                              CanUserSelect="True"
                              CanUserDeleteRows="False"

Dragging row format

Hi Telerik,

In RadGridView, when dragging a row it defaults with a line indicator of the target position. How can I change this format to a highlighted target row instead while dragging a row? I can't find any tricks to achieve this. Please help! Thanks.

ToolTip Issue for Button

Hi Telerik Team,
I had created a style for ToolTip and I applied it for a button. But it is not applying and displays System.Windows.Style as a ToolTip. The following is the ToolTip Style which I created.

<

Style x:Key="ToolTipStyle1" TargetType="{x:Type ToolTip}">

<Setter.Value>

</TextBlock>

</StackPanel>

</TextBlock>

</StackPanel>

</Border>

</ControlTemplate>

</Setter.Value>

</Setter>

</Style>

I had applied the style in the following code:

<

Button Content="Show Tool Tip" Height="23" Margin="288,226,0,0" Name="Button2" VerticalAlignment="Top" HorizontalAlignment="Left" Width="85" ToolTip="{StaticResource ToolTipStyle1}" />

Please let me know any mistakes available in the Style.

Thanks & Regards

TreeListView Row Visibility

Hi there,

Is that possible to bind the Visibility property of TreeListView Row into a ViewModel's property?

For example here is the format of the ViewModel

public class EntryViewModel

{

private String _name;

private ObservableCollection<EntryViewModel> _items;

private Boolean _isVisible;

public EntryViewModel(String name, Boolean isVisible = true)

{

_name = name;

_items = new ObservableCollection<TSEntryViewModel>();

_isVisible = isVisible;

}

public String Name

{

get { return _name;}

set { _name = value; }

}

public ObservableCollection<EntryViewModel> Items

{

get { return _items; }

set { _items = value; }

}

public Boolean IsVisible

{

get { return _isVisible; }

set { _isVisible = value; }

}

So, is that possible to set the Visibility property of TreeListView row to Collapsed when IsVisible value is false?
I've tried to look for some APIs here but can't find any API that can serve my purpose.
