treeview nodes are not refreshing

[dmsruthi]

Hi,
am working on TreeView, I edited node text and I am concatinating some text to edited text, but its not reflecting on treeview i.e treeview is not refreshing.

I am concatinating text in afterlabeledit event.


I would appreciated if anyone post the solution

Thanks

I'm not sure I entirely understand your problem. Can you post some code?

Hi thanks for the quick reply,


e.Node.Text=" ("+ area.Count+") "+e.Label;

here I am concatinating extra text to the node, but its now showing on next


here is my code.


///////////////////////////////////////////////////////
private void conferenceTreeView1_AfterLabelEdit(object sender, System.Windows.Forms.NodeLabelEditEventArgs e)
{
if (e.Label != null)
{
if(e.Label.Length > 0)
{
if (e.Label.IndexOfAny(new char[]{'@', '.', ',', '!'}) == -1)
{
e.Node.EndEdit(false);
AbstractArea area = (AbstractArea)e.Node.Tag;
object e.Node.Text=" ("+ area.Count+") "+e.Label;
}
else
{
/* Cancel the label edit action, inform the user, and
place the node in edit mode again. */
e.CancelEdit = true; e.Node.BeginEdit();
}
}
else
{
/* Cancel the label edit action, inform the user, and
place the node in edit mode again. */
e.CancelEdit = true;
e.Node.EndEdit(true);
}
this.conferenceTreeView1.BeginLabelEdit = false;
}

}

This doesn't make sense.

if (e.Label.IndexOfAny(new char[]{'@', '.', ',', '!'}) == -1)

That if statement will be true if one of the items is found, yet, you cancel the edit. Why?


Also: You might want to look at regular expressions. I assume you're trying to pull an email? create an email regex.

I am not allowing any special characters in node text.

thats different scenario,

but my treeview is not refreshing, I am explicitly changing node text, but its not appearing on treeview


Thanks

Your code didn't compile. This code now works for me and my tree view.

private void treeView1_AfterLabelEdit(object sender, System.Windows.Forms.NodeLabelEditEventArgs e)
		{
			if (e.Label != null)
			{
				if(e.Label.Trim().Length > 0)
				{
					if (e.Label.IndexOfAny(new char[]{'@', '.', ',', '!'}) == -1)
					{   
						//The label does not contain any of the bad characters
						e.Node.EndEdit(false);
						//AbstractArea area = (AbstractArea)e.Node.Tag;
						//e.Node.Text=" ("+ area.Count+") "+e.Label;    
					}
					else
					{
						//The label contains one of the bad characters
						e.CancelEdit = true;                                    
						e.Node.BeginEdit();
					}
				}
				else
				{
					//The Label does not contain any text and is not just spaces.
					e.CancelEdit = true;
					e.Node.EndEdit(true);
				}
				
			}
		}

hey here I am adding some extra text but its not appearing on node

AbstractArea area = (AbstractArea)e.Node.Tag;
e.Node.Text=" ("+ area.Count+") "+e.Label;

Thanks

What is abstractarea?

 

[dmsruthi]

thats a special class,
forget about that

e.Node.Text="SOME EXRTRA TEXT"+ e.Label;
