How to display check boxes for the nodes in a WinForms TreeViewAdv control?

Platform: WinForms |
Control: TreeViewAdv |

Checkbox

You can control the display of check boxes for each TreeNodeAdvs in the TreeViewAdv control with the TreeNodeAdv.ShowCheckBoxes property. The following code sample shows how you can display check boxes only for the first level of child nodes below the parent node:

C#

//Show Checkbox only for the first level of child nodes
int i = 0;
while (i < this.treeViewAdv1.Nodes.Count)
{
    int j = 0;
    while (j < this.treeViewAdv1.Nodes[i].Nodes.Count)
    {
        this.treeViewAdv1.Nodes[i].Nodes[j].ShowCheckBox = true;
        j++;
    }
    i++;
}

VB

'Show Checkbox only for the first level of child nodes
Dim i As Integer = 0
While i < Me.treeViewAdv1.Nodes.Count
    Dim j As Integer = 0
    While j < Me.treeViewAdv1.Nodes(i).Nodes.Count
        Me.treeViewAdv1.Nodes(i).Nodes(j).ShowCheckBox = True
        j = j + 1
    End While
    i = i + 1
End While
