I am new in windows application. So please help to find out the solution for the same.

So can anyone tell me how to do it?

Answer 1

Assuming that you are adding the check boxes to the nodes by setting the NodeStyle to Checkbox you could handle the AfterCheck event and update the children in this event:

void ultraTree1_AfterCheck(object sender, NodeEventArgs e)
{
    foreach (UltraTreeNode node in e.TreeNode.Nodes)
        node.CheckedState = e.TreeNode.CheckedState;
}

Answer 2

You have to use the Property SelctionType as Extended to Allow Multiple Selection.

Me.UltraTree1.Override.SelectionType =
    Infragistics.Win.UltraWinTree.SelectType.Extended

Create Method Iterate the Each node under Checked Nodes, and Selected = true

node Varible is the node which you Checkecd , you will get the Node form EventArgs

  foreach(UltraTreeNode child in node.Nodes)

    node.Selected = true;
