Hello,

You could call "f1.Refresh()".

All the best,

Hi,

Control.Invalidate() exists so you can signal something has changed that affects
the look of your Control; it sill cause a repaint to occur.

What have you tried ? The obvious is to repeat this code with a 1 and a 2 in place of the 0.

Why don't new and override appear at the same point in the declaration? Mad | :mad:

public override void Blah(){}

but

new public void Blah(){}

You can do it just like you want!
All is possible:

public override void Blah(){}
override public void Blah(){}
new public void Blah(){}
public new void Blah(){}

So take a big breath and relax. Wink | ;)

All the best,

Thanks mate! I blame Wrox for printing one before and one after the public.

But it seems partial must always be last when included?

How to bring Ghost Image during Dragging

Hello,

Yes, that's true!
But in fact it is also limited to classes I guess and so I would also not se it as unconsistend.
public class partial MyClass

All the best,

Martin

Getting the node name in TreeView

Divya Kasavar18-Jun-07 23:52

18-Jun-07 23:52

Hi. I am having problem in getting the name of the node in treeview control. When I searched in events list there is no exact event which matches this scenario. If I select "DoubleClick" event, I dont get any reference of currently selected node.
The contents of tree (i.e nodes) are generated dynamically. When clicked on any of this node, I should get that node's name
Should I create new event of my own? If so, how to do that? tell me how should i proceed.

Thanks,Divya

No you dont need to create a new event.
You can use the NodeMouseClick event of the treeview.
e.Node.Name will return you the Node Name.
In btw, make sure when you add a node dynamically, you specify its name also Rose | [Rose]

My target Framework is 1.1. NodeMouseClick event is present in 2 and 3 framework. Is there any method to do in 1.1 framework?

Thanks

Use AfterSelect event instead.
Make sure you handle the first click as it will return the name of root node.

treeView1_AfterSelect(), displays node name for just a single click.i.e as soon as u select a node, its name is displayed.
But I want name of the node to be displayed after double clicking it.

Thanks,Divya

Hi Bhardwaj, thanks for ur reply

Here is the solution for my problem..

Use DoubleCLick event itself. Just need to typecast the sender object to TreeView

private void treeView1_DoubleClick(object sender, System.EventArgs e)<br />
{<br />
    TreeView myTree = (TreeView)sender;<br />
    MessageBox.Show(myTree.SelectedNode.Text);<br />
}

Dear Divya

In the below code you can find your solution :

private void treeView1_AfterSelect(object sender, TreeViewEventArgs e)
{
MessageBox.Show(e.Node.Name.ToString());
}

Also, you can read my article about storing tree in SQL at the below link:
