[Solved] Hirerchical RowDetailsTemplate

[Prakash]

 

Hi

Please find the attachements

From the sample provided, I can achieve One level of Hirerchy using rowdetailstemplate. Please can u give me sample for
having more than one of level of hirerchy using the same rowdetailstemplate.

For Ex:


<DataTemplate x:Key="ChildRowDetailsTemplate">
<telerik:RadGridView ItemsSource="{Binding Hobbies}" />
</DataTemplate>

<DataTemplate x:Key="RowDetailsTemplate">
<telerik:RadGridView Name="playersGrid"
ItemsSource="{Binding Players}"
AutoGenerateColumns="False"
ShowGroupPanel="False" RowDetailsTemplate="{StaticResource hildRowDetailsTemplate}"
RowDetailsVisibilityChanged="OnRowDetailsVisibilityChanged">
<telerik:RadGridView.Columns>
<telerik:GridViewDataColumn Header="Name"
DataMemberBinding="{Binding Name}">
</telerik:GridViewDataColumn>
<telerik:GridViewDataColumn Header="Number"
DataMemberBinding="{Binding Number}">
</telerik:GridViewDataColumn>
</telerik:RadGridView.Columns>
</telerik:RadGridView>
</DataTemplate>


Here ChildRowDetailsTemplate Datatemplate is referred as static resource for Grid playersGrid. i could get the hirerchical view ...

Sample which i worked in the below link
http://blogs.telerik.com/rossenhristov/posts/09-12-01/how_to_toggle_row_details_one_at_a_time_with_telerik_radgridview_for_silverlight.aspx

Changes done with Player class

private List<Hobbies> hobbies; -- Variable

public List<Hobbies> Hobbies
{
get
{
if (null == this.hobbies)
{
this.hobbies = new List<Hobbies>();
}
return this.hobbies;
}

set
{
if (value != this.hobbies)
{
this.hobbies = value;
this.OnPropertyChanged("Hobbies");
}
}
}

Constructor of the Player Grid

public Player(string name, int number, Position position, string country)
{
this.name = name;
this.number = number;
this.position = position;
this.country = country;
this.Hobbies = new List<Hobbies>()
{
new Hobbies() { Name = "Pepe Reina", ID = 1},
new Hobbies() { Name = "Steven Gerrard", ID = 2}
};
}


These are the changed done ... I adding this Hobbies to the Child ChildRowDetailsTemplate radgridview..

Hello Prakash,

Basically you need to define another HierarchyChildTemplate that will define the 2nd level of hierarchy.

I have attached a sample application which demonstrates this approach. Hope it helps.

How Can i implement

 

clubsGrid.ExpandAllHierarchyItems(); inside the button Click from the sample provided previously in this thread.

Expand All Hierarchy Items will work only when it is added with Hierarchy Child Template?

How can i implement the same using RowDetailsTemplate?

Please provide me the sample for my requirement.
and while loading or expanding rows which has no child items to be displayed toggle button shouldn't be appear.
