TreeView expandall

[Kathy Gray]

Is there a way to expand all the nodes in the treeview without going through and expanding them one at a time? Similar to the expandall function in the asp treeview?

Hi Kathy,

Can you try this function and let me know if this helps?

[C#]
this.treeViewAdv1.ExpandAll();

I get this error:

'expandall' is not a member of 'Syncfusion.Web.UI.WebControls.Tools.TreeView'.

Hi Kathy ,

You can expand all the parent nodes by using the Expanded property of the TreeViewNode. Please refer to the following code snippet.

[C#]

        foreach (TreeViewNode m_node in this.TreeView1.Items)
        {
            m_node.Expanded = true;
        }

Please let me know if this helps.
