SplitContainer panel scroll bar.

[snayyagari]

I have a split container on the form. On the left panel and right panel I have tree views. I have set the tree view scroll bars to false. When the treeviews increase in size, tthe panels doesn't show any scroll bar even though autoscroll property of the panels are set to true. How can I show the scroll bars of the panel? I need to synchronise both the scroll bars later.

Regards
Surya

can you put your code here so that it would be easy to identify your mistake

Here is my code

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;

namespace Scrollbar1
{
public partial class Form1 : Form
{
TreeView tv1 = new TreeView();
TreeView tv2 = new TreeView();
System.Windows.Forms.VScrollBar VScrollBar1 = new VScrollBar();
public Form1()
{
InitializeComponent();
this.splitContainer1.Panel2.AutoScroll = true;
this.splitContainer1.Panel1.AutoScroll = true;
this.splitContainer1.Panel1.VerticalScroll.Visible = true;
this.splitContainer1.Panel2.VerticalScroll.Visible = true;
//this.splitContainer1.Panel1.VerticalScroll.Maximum = this.splitContainer1.Panel2.VerticalScroll.Maximum;
//splitContainer1.Panel2.Scroll += new ScrollEventHandler(splitContainer1_Scroll);
}



private void Add_Click(object sender, EventArgs e)
{
int intCounter;

for (intCounter = 0; intCounter < 60; intCounter++)
{
tv1.Nodes.Add(Convert.ToString(intCounter));
}
splitContainer1.Panel1.Controls.Add(tv1);


for (intCounter = 0; intCounter < 100; intCounter++)
{
tv2.Nodes.Add(Convert.ToString(intCounter));
}

splitContainer1.Panel2.Controls.Add(tv2);

tv1.Dock = DockStyle.Fill;
tv2.Dock = DockStyle.Fill;

tv1.Scrollable = false;
tv2.Scrollable = false;

splitContainer1.Panel1.AutoScroll = true;
splitContainer1.Panel2.AutoScroll = true;
}

private void splitContainer1_Panel2_Scroll(object sender, ScrollEventArgs e)
{
this.splitContainer1.Panel1.VerticalScroll.Value = e.NewValue;
}

private void splitContainer1_Scroll(object sender, ScrollEventArgs e)
{
if (e.ScrollOrientation == ScrollOrientation.VerticalScroll)
{
splitContainer1.Panel1.VerticalScroll.Value = e.NewValue;
}
}

private void Form1_Load(object sender, EventArgs e)
{


}

private void Form1_Resize(object sender, EventArgs e)
{
tv1.Dock = DockStyle.Top;
tv1.Dock = DockStyle.Top;
splitContainer1.Panel2.ScrollControlIntoView(tv2);
}

private void splitContainer1_SplitterMoved(object sender, SplitterEventArgs e)
{

}
}
}

Any solution for this.... :-(

[vcdebugger]

is.splitContainer1.Panel2.AutoScroll = true;
this.splitContainer1.Panel1.AutoScroll = true;
this.splitContainer1.Panel1.VerticalScroll.Visible = true;
this.splitContainer1.Panel2.VerticalScroll.Visible = true;

Here you are setting "true" to the visible flag for vertical scroll bar and for Autoscroll you are not setting it for the flag but directly assigning to the Autoscroll variable - Is this correct, verify once !

[snayyagari]

Thanks for pointing it. Now I have changed it to


this.splitContainer1.Panel2.AutoScroll = true;
this.splitContainer1.Panel1.AutoScroll = true;
//this.splitContainer1.Panel1.VerticalScroll.Visible = true;
//this.splitContainer1.Panel2.VerticalScroll.Visible = true;
this.splitContainer1.Panel1.VerticalScroll.Maximum = this. splitContainer1. Panel2. VerticalScroll . Maximum;

But now the vertical scroll bar are invisible. Even though the treeview height is more than the panel height the scroll bars are not visible.
