Solution 1

Just try this....

SQL

int a = treeView1.SelectedNode.Parent.Index;
int b = treeView1.SelectedNode.FirstNode.Index;

Hello,

I solved the problem which i mentioned above.

Now want to ask another one is that,i want list of all parent node and child node.

example: I have total 4 parent node as;

All ....parent node

ID ....parent node

1 ..child node

2 ..child node

Name ....parent node

abc ..child node

xyz ..child node

Address ....parent node

123 ..child node

124 ..child node

my question is that, i) i want list of all parent and child nodes.

ii) Also ,When i select or check option all then automatically other parent and child node

get select.

iii) Also,when i select particular node that time title of this node shoulg get bold.For it i get solution as;

private void CheckAllChildNodes(TreeNode treeNode, bool nodeChecked)
{
TreeNode oMainNode = oYourTreeView.Nodes[0];
PrintNodesRecursive(oMainNode);

int x = treeView1.SelectedNode.Index;
Font boldFont = new Font(treeView1.Font, FontStyle.Bold);

foreach (TreeNode node in treeNode.Nodes)
{
node.Checked = nodeChecked;
if (node.Nodes.Count >= 0)
{

this.CheckAllChildNodes(node, nodeChecked);

}

treeView1.Nodes[s].NodeFont = new Font(treeView1.Font, FontStyle.Bold);

private void treeView1_AfterCheck(object sender, TreeViewEventArgs e)
{
if (e.Action != TreeViewAction.Unknown)
{
if (e.Node.Nodes.Count > 0)
{
/* Calls the CheckAllChildNodes method, passing in the current
Checked value of the TreeNode whose checked state changed. */
// s = e.Node.ToString();
s= e.Node.Index;
this.CheckAllChildNodes(e.Node, e.Node.Checked);
}
}

}

By using it i get bold letter for parent node.but,for first parent node "All" above code not applicable.I checked the index for it.but only for 1st option title of node not get bold.
