Hierarchial TreeviewAdv node selection

[Administrator]

Hi,
Is it possible to have a hierarchical selection in the tree with check options as shown below. If the user selects A then if B is selected previously it should be unselected. This can be done by setting the SelectionMode property to single. Similarly When child nodes if A2 is Selected then all the selected items of the other child A1 should be unselected including parent B and its children should be unselected. But the level 3 child nodes can be multi-selected.
How to achieve this using TreeViewAdv?

A
A1
a1
a2
A2
a1
a2
B
B1
b1
b2
B2
b1
b2

Thanks in advance

Hi Nitroxn,

Thank you for your interest in Syncfusion Products.

We can perform multiple selection in the sub nodes and single selection in the parent nodes in the TreeviewAdv's click event. Kindly refer to the code snippet and the sample given below that illustrates this

        private void treeViewAdv1_Click(object sender, EventArgs e)
        {
            Point controlPoint = this.treeViewAdv1.PointToClient(Control.MousePosition);
            TreeNodeAdv node = this.treeViewAdv1.GetNodeAtPoint(controlPoint);
            if (node != null)
            {
                if (node.Level == 3)
                {
                    this.treeViewAdv1.SelectionMode = TreeSelectionMode.MultiSelectSameLevel;
                }
                else
                {
                    for(int i=0;i                    {
                        if (this.treeViewAdv1.SelectedNodes[i].Level == 3)
                        {
                            this.treeViewAdv1.SelectedNodes.Clear();
                            this.treeViewAdv1.SelectedNodes.Add(node);
                        }
                    }
                    this.treeViewAdv1.SelectionMode = TreeSelectionMode.Single;
                }
            }
        }
