How to create hierarchies of header items?

Article Information

Article relates to VIBlend DataGrid for Silverlight

How To

Create hierarchies and fill the cells with data in unbound mode.

Solution

In order the add Rows and Columns in unbound mode, you should do the following:

C#

this.DataGrid.RowsHierarchy.CompactStyleRenderingEnabled = false;
for (int i = 0; i < 10; i++)
{
    HierarchyItem row = this.DataGrid.RowsHierarchy.Items.Add("Row" + i);
    HierarchyItem column = this.DataGrid.ColumnsHierarchy.Items.Add("Column" + i);

    for (int j = 0; j < 3; j++)
    {
        HierarchyItem subRow = row.Items.Add("Row" + i + "." + j);
    }
}
   
VB .NET

Me.DataGrid.RowsHierarchy.CompactStyleRenderingEnabled = False
For i As Integer = 0 To 9
	Dim row As HierarchyItem = Me.DataGrid.RowsHierarchy.Items.Add("Row" & i)
	Dim column As HierarchyItem = Me.DataGrid.ColumnsHierarchy.Items.Add("Column" & i)

	For j As Integer = 0 To 2
		Dim subRow As HierarchyItem = row.Items.Add("Row" & i + AscW("." )+ j)
	Next j
Next i

In order to fill the data grid with data, do the following:

C#

for (int i = 0; i < 10; i++)
{
    HierarchyItem row = this.DataGrid.RowsHierarchy.Items[i];
    for (int j = 0; j < 10; j++)
    {
        HierarchyItem column = this.DataGrid.ColumnsHierarchy.Items[j];
        this.DataGrid.CellsArea.SetCellValue(row, column, "Cell" + i + "." + j);
        for (int p = 0; p < 3; p++)
        {
            this.DataGrid.CellsArea.SetCellValue(row.Items[p], column, "Cell" + p + "." + j);              
        }
    }
}
        
this.DataGrid.RowsHierarchy.ExpandAllItems();
this.DataGrid.ColumnsHierarchy.ExpandAllItems();
this.DataGrid.RowsHierarchy.AutoResize(AutoResizeMode.FIT_ALL);
this.DataGrid.ColumnsHierarchy.AutoResize(AutoResizeMode.FIT_ALL);
   
VB .NET

For i As Integer = 0 To 9
	Dim row As HierarchyItem = Me.DataGrid.RowsHierarchy.Items(i)
	For j As Integer = 0 To 9
		Dim column As HierarchyItem = Me.DataGrid.ColumnsHierarchy.Items(j)
		Me.DataGrid.CellsArea.SetCellValue(row, column, "Cell" & i + AscW("." )+ j)
		For p As Integer = 0 To 2
			Me.DataGrid.CellsArea.SetCellValue(row.Items(p), column, "Cell" & p + AscW("." )+ j)
		Next p
	Next j
Next i

Me.DataGrid.RowsHierarchy.ExpandAllItems()
Me.DataGrid.ColumnsHierarchy.ExpandAllItems()
Me.DataGrid.RowsHierarchy.AutoResize(AutoResizeMode.FIT_ALL)
Me.DataGrid.ColumnsHierarchy.AutoResize(AutoResizeMode.FIT_ALL)
