how to give the chance to update or rename the treelist node at the time of inserting?

Question

I'm using xtratreelist control from the DevExpress. I'm creating child node when user clicks on the parent node. And that time it adds the default named child node. But i want to show the cursor at the newly inserted child node for editing the child nodes text.

private void addNewGroupToolStripMenuItem_Click(object sender, EventArgs e)
{
 TreeListNode childNode = treeList1.AppendNode(new object[] { "My Group" + DateTime.Now }, 1);
 treeList1.FocusedNode = childNode;
 treeList1.ShowEditor();
 treeList1.ExpandAll();
}

I've implemented same functionality in the treeview control. By using treeview's LabelEdit property & treeView's AfterLabelEdit() method. But i'm getting these property & method in the treelist control.

whether is it possiblem? If yes then suggest some information depending on this.

thanks.

Answer 1

I suspect that you are using the TreeList's AppendNode method to create a new node. If so, this method returns a new TreeList node object. So, to be able to edit this node value, you should:

1) focus this node;

2) open the editor;

This can be done using the following code:

TreeListNode node = treeList.AppendNode(..);
treeList.FocusedNode = node;
treeList.ExpandAll();
treeList.ShowEditor();

UPDATE: I've modified the code and it works properly. The problem was caused by the ExpandAll method which closes the editor...
