Does anyone have a problem with their device freezing when using the
TreeView and scrolling horizontally?

(I have the latest SP, thanks)

I have a treeview that after I fill it with data, if I scroll to the right
it freezes the entire device, EVERYTIME. Not just on occasion.

I already tried removing it and re-adding the tree view, it doesn't help.

This code creates the problem for me (pretty simple):
---------------------------------------------------

using System;
using System.Drawing;
using System.Collections;
using System.Windows.Forms;
using System.Data;

public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.TreeView treeView1;
private System.Windows.Forms.MainMenu mainMenu1;
public Form1()
{
InitializeComponent();
}
protected override void Dispose( bool disposing )
{
base.Dispose( disposing );
}

private void InitializeComponent()
{
this.treeView1 = new System.Windows.Forms.TreeView();
this.treeView1.ImageIndex = -1;
this.treeView1.Location = new System.Drawing.Point(24, 24);
this.treeView1.SelectedImageIndex = -1;

this.Controls.Add(this.treeView1);
this.Text = "Form1";
}

protected override void OnLoad(EventArgs e)
{
base.OnLoad (e);
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it
scroll to the right");
this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it

this.treeView1.Nodes.Add("this is some text to fill the view and make it

}
static void Main()
{
Application.Run(new Form1());
}

I tried that sample with emulator and a device with SP2 and didn't have any
problems. What device are you testing on and what SP do you have?
 
I have an i700 and it does the same thing with both SP2 and SP3. I have a
clean image with SP2 and tried it before and after installing the SP3.

Honestly, I'm more releaved that it's my problem. I was concerned the
application I was designing was useless. Although I'd love to have it work
for me also.

Thanks for the reply.
 
just some further info. I did a hard reset (I'm running the 2003 upgrade
btw) and installed ONLY the framework and my applicaton. I got it do the
same thing if I slide the bar back and forth about 10 times

Now obviously most people won't do that, but it does seem to be much more
noticable when I have a couple other things running. Maybe it's a ram issue?
 
Cannot replicate with your sample in the PPC emulator (CF RTM)
or on a PPC (SP1).

Cheers
Daniel
