TreeView Check Box population

Question

Hi everyone...

I have populated a treeview. (like Category.JPG in the zip file), Now I am getting the datatable containing the treeview node values. and on the basis of that I need to make "checked" the check boxes at the time of page load. I am getting the Parent nodes only by using the following code below. But unable to get the child nodes.

            DataTable dt = ds1.Tables[0];
            foreach (TreeNode node in TreeViewArticleCatagory.Nodes)
            {
                foreach (DataRow dr in dt.Rows)
                {
                    if (Convert.ToString(dr["Item"]) == node.Value)
                    {
                        node.Checked = true;
                        //TreeViewArticleCatagory.SelectedNode.Checked = true;
                    }
                }
            }

Please help me....

Thanks in advance.....

yes at last completed.... private void methode() { ds1 = new DataSet(); ds1 = oCategory.GetCategoriesOfArticle(ArticleID); // Use your own methode if (ds1 !=null && ds1.Tables[0].Rows.Count > 0) { foreach (TreeNode node in TreeViewArticleCatagory.Nodes) { CheckNodes(node); } } } private void CheckNodes(TreeNode _node) { if (_node.ChildNodes.Count > 0) { CheckIfNodeValueExistsInDataTable(_node ds1); foreach (TreeNode _childNode in _node.ChildNodes) { CheckNodes(_childNode); } } else { CheckIfNodeValueExistsInDataTable(_node ds1); } } private void CheckIfNodeValueExistsInDataTable(TreeNode _node DataSet _dsCatogories) { DataTable dtNodes = _dsCatogories.Tables[0]; DataRow[] drow= dtNodes.Select(Item=' + _node.Value+'); if (drow != null && drow.Length > 0) { _node.Checked = true; } }
