Declarative Heirarchy defintion

[JTango]

Hi guys,

Are there plans to allow parent/child grid hierarchies to be declared declaratively in XAML in future releases of the DataGrid? If not, this is definitely a feature I would like to request. I would make the construction of child grids much simpler and easier to implement.

Cheers

Justin

Hello JTango,

This functionality has always been on our TODO list.
This Q we will be making some improvements to the hierarchy feature as a part the of our Silverlight porting effort.
Of course we will make that available both for WPF and Silverlight.

Is there any way to hide a child view's column declaratively or by code ? our is this a plan too ?

Hello dogu.tumerdem,

You can set AutoGenerateFieldDescriptors to false for desired GridViewTableDefinition and declare columns programmatically:

            RadGridView1.ItemsSource = ExamplesDB.GetEmployees();

            TableRelation relation = new TableRelation();
            relation.FieldNames.Add(new FieldDescriptorNamePair("EmployeeID", "EmployeeID"));

            GridViewTableDefinition definition = new GridViewTableDefinition();
            definition.AutoGenerateFieldDescriptors = false;

            GridViewDataColumn column = new GridViewDataColumn();
            column.DataMemberBinding = new Binding("OrderID");
            column.HeaderText = "Order ID";
            column.IsFilterable = false;
            definition.FieldDescriptors.Add(column);

            column = new GridViewDataColumn();
            column.DataMemberBinding = new Binding("OrderDate");
            column.DataFormatString = "{0:d}";
            column.HeaderText = "Order Date";
            column.IsFilterable = false;
            definition.FieldDescriptors.Add(column);

            definition.DataSource = ExamplesDB.GetOrders();
            definition.Relation = relation;

All the best,

Do you guys have any updates on this feature? I think you had plan to build something for this by Q1...

I too need this feature badly. I'm trying to follow 100% declarative code for View definition in my project. I got stuck on defining Hierarchial grid using XAML and I don't know whether RadGridView supports this or not?

Please provide more information on how to define custom column header with Combo Box, Check Box... on the child grid in hierarchy.

Hi Selvam,

Refactoring the hierarchy is a big and heavy task and unfortunately we have still some work to do. As you mention it is critical for you to declaratively define hierarchy children settings I would recommend to try the approach stated here. Basically it is a hack to prevent the child grid in hierarchy to automatically build columns and settings and respect the XAML settings. Please have a look at the example in my  post there. Meanwhile we are doing our best to push the improved hierarchy logic to a shippable state.


Best wishes,
