如何在visual studio 2005中制做左右上下移动的Listbox？

制作可上下左右移动的 ListBox:

方法:

1.新建页面,拖放如下控件: 两个ListBox ,6个button,样式如下

各个button的功能

>> 左移

<< 右移

↑上移

↓下移

C全部清空

>> 代码如下:

protected void Button1_Click(object sender, EventArgs e)
{
try
{
this.ListBox2.Items.Add(this.ListBox1.SelectedItem.Text.ToString());
}
catch (Exception)
{
// this.Response.Write("<script language=javascript>alert('Please select some items before you click it!');history.go(-1)</script>");
}
}

<<代码如下:

protected void Button2_Click(object sender, EventArgs e)
{
try
{
this.ListBox2.Items.Remove(this.ListBox2.SelectedItem.Text.ToString());
}
catch (Exception)
{
//this.Response.Write("<script language=javascript>alert('Please select some items before you click it!');history.go(-1)</script>");
}
}

↑代码如下:

protected void Button4_Click(object sender, EventArgs e)
{
try
{
int i = this.ListBox2.SelectedIndex;
int j = this.ListBox2.Items.Count;
if ((j > i) && (i != 0))
{
string sitem = this.ListBox2.SelectedItem.Text.ToString();
this.ListBox2.Items.RemoveAt(i);
this.ListBox2.Items.Insert(i - 1, sitem);
this.ListBox2.SelectedIndex = i - 1;

}
}
catch (Exception)
{
//this.Response.Write("<script language=javascript>alert('Please select some items before you click it!');history.go(-1)</script>");
}
}

↓代码如下:

protected void Button3_Click(object sender, EventArgs e)
{
try
{
int i = this.ListBox2.SelectedIndex;
int j = this.ListBox2.Items.Count;
if ((j > i) && (i != j - 1))
{
string sitem = this.ListBox2.SelectedItem.Text.ToString();
this.ListBox2.Items.RemoveAt(i);
this.ListBox2.Items.Insert(i + 1, sitem);
this.ListBox2.SelectedIndex = i + 1;

}
}
catch (Exception)
{
//this.Response.Write("<script language=javascript>alert('Please select some items before you click it!');history.go(-1)</script>");

}
}

C代码如下:

protected void Button6_Click(object sender, EventArgs e)
{
this.ListBox2.Items.Clear();
}

最后显示如图:

next放你要操作的代码即可
