Hi Rasika,

Thank you for using Syncfusion products.

The reported requirement can be achieved by using Custom control property in TreeNodeAdv. Please refer the below code example. 

Code Snippet[C#]:

int i = 0;
int TotalNodeCount = 4;
//To add the Parent node
for (i = 0; i < TotalNodeCount; i++)
     {
           TreeNode = new TreeNodeAdv();
           TreeNode.Text = "node" + nodenumber.ToString();
           nodenumber++;
           this.treeViewAdv1.Nodes.Add(TreeNode);
      }
 
     //To Add child node
     foreach (TreeNodeAdv node in this.treeViewAdv1.Nodes)
     {
         for (int childnode = 0; childnode <= 30; childnode++)
            {
                TreeNode = new TreeNodeAdv();
                TreeNode.Text = "node" + nodenumber.ToString();
                nodenumber++;
                node.Nodes.Add(TreeNode);
            }
     }
 
     for (int addcustom = 0; addcustom < 4; addcustom++)
     {
           //To add the GridGrouping Control.
           foreach (TreeNodeAdv node in Collect(this.treeViewAdv1.Nodes[addcustom].Nodes))
           {
                GridGroup = new GridGroupingControl();
 
                GridGroup.GridVisualStyles = GridVisualStyles.Metro;
                GridGroup.TopLevelGroupOptions.ShowCaption = false;
                if (node.CustomControl == null)
                  {
                      node.CustomControl = GridGroup;
                      GridGroup.DataSource = dt;
                      node.CustomControl.Width = 300;
                      node.Height = 80;
                   }
            }
     }

Hi Rasika,

 

Thanks for contacting Syncfusion Support.

 

The DataTable can be retrieved from GridGroupingControl which is loaded as custom control for TreeNodeAdv, by using the below code example.

 

Code Example[C#]:

 

if (this.treeViewAdv1.SelectedNode != null && this.treeViewAdv1.SelectedNode.CustomControl != null)
            {
                //To get the DataTable from GridGroupingControl.
                foreach (DataRow dr in ((this.treeViewAdv1.SelectedNode.CustomControl as GridGroupingControl).DataSource as DataTable).Rows)
                {
                    //To get the Row value from DataTable.
                    this.listBox1.Items.Add(dr["FirstName"].ToString());
                }
            }
