Different child templates on second level hierarchical model

[flisak]

Hi,

Is it possible to configure RadGridView to have different child templates on the same level of hierarchical data rows? Or to have different columns collections for each group?

I want to accomplish something like this:

[Data model]
Class Flat
{
 string name; 
 List<Room> rooms;
}

Class Room
{
 string name;
 bool table;
 bool bath;
 bool desk;
 int walls;
}

[View]

1. Expandable rows with objects  "Flat" (visible columns: Name)
2. Second hierarchy with rooms, but on this level different columns visible for every room type:

If room name is "Bathroom" then columns are: name, bath, walls.
If room name is "Saloon" then columns are: name, table, walls.
etc.

Is it feasible on one grid?

Best Regards
 Krzysztof

Hello Krzysztof,

This option is not available in RadGridView by design. Child views at the same level that have a common template share the same DataSource and the same Columns collection. However, you can add multiple child templates to a parent template. This scenario is demonstrated in our demo application. Check the GridView >> Hierarchy >> Tabbed Views example. You can control the tab visibility by handling the ViewCellFormatting event. Consider the sample below:

void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
{
    GridDetailViewCellElement cell = e.CellElement as GridDetailViewCellElement;
    if (cell != null)
    {
        cell.PageViewElement.Items[1].Visibility = ElementVisibility.Collapsed;
    }
}

I hope this helps. If you need further assistance, I will be glad to help.
 
All the best,
