Iterating child rows of a parent row in hierarchy

HOW-TO
Iterate the child rows collection of a chosen parent row in hierarchy RadGridView.

SOLUTION
In order to iterate the child rows collections you could use grid template's GetChildRows method:

VB.Net

Private Sub IterateChildRows(ByVal rowInfo As GridViewDataRowInfo)

Dim expandedState As Boolean = rowInfo.IsExpanded

rowInfo.IsExpanded = True

Dim childRows As GridViewRowInfo() = rowInfo.ViewTemplate.ChildGridViewTemplates(0).GetChildRows(rowInfo)

For i As Integer = 0 To childRows.Length - 1

'do something with childRows[i]:

Console.WriteLine(childRows(i).Cells(0).Value)

Next

rowInfo.IsExpanded = expandedState

Me.radGridView1.GridElement.Update(GridUINotifyAction.Reset)

End Sub

C#

private void IterateChildRows(GridViewDataRowInfo rowInfo)

{

bool expandedState = rowInfo.IsExpanded;

rowInfo.IsExpanded = true;

GridViewRowInfo[] childRows =

rowInfo.ViewTemplate.ChildGridViewTemplates[0].GetChildRows(rowInfo);

for (int i = 0; i < childRows.Length; i++)

{

//do something with childRows[i]:

Console.WriteLine(childRows[i].Cells[0].Value);

}

rowInfo.IsExpanded = expandedState;

this.radGridView1.GridElement.Update(GridUINotifyAction.Reset);

}
