Move Items from one ListBox to another in C#
To move items from ListBox1 to ListBox2 and vice-versa, we
would have to write code for four buttons.
·
Forward: to move selected item in listbox1 to
listbox2.
·
Forward All: to move all items from listbox1 to listbox2
·
Remove: to remove item from listbox2 and add in
listbox1
·
Remove All: to remove all items in listbox2 and
add in listbox1
Forward
private void btnforward_Click(object
sender, EventArgs e)
{
try
{
if
(listBox1.Items.Count > 0)
{
// checking
whether listbix1 has items or not if yes then moving items
listBox2.Items.Add(listBox1.SelectedItem.ToString());
listBox1.Items.Remove(listBox1.SelectedItem);
}
}
catch
(Exception ex)
{
MessageBox.Show(ex.Message);
}
//selecting first item of
listbox.
if(listBox1.Items.Count>0)
listBox1.SelectedIndex = 0;
listBox2.SelectedIndex =
listBox2.Items.Count - 1;
}
Forward All
private
void btnForwardAll_Click(object sender, EventArgs
e)
{
try
{
//moving all
items from listbox1 to listbox2
listBox2.Items.AddRange(listBox1.Items);
listBox1.Items.Clear();
}
catch
(Exception ex)
{
MessageBox.Show(ex.Message);
}
listBox2.SelectedIndex = 0;
}
Remove
private
void btnRemove_Click(object
sender, EventArgs e)
{
try
{
if
(listBox2.Items.Count > 0)
{
//checking whether listbox2 has items or
not. If yes then moving
//selected
item from listbox2 to listbox1
listBox1.Items.Add(listBox2.SelectedItem.ToString());
listBox2.Items.Remove(listBox2.SelectedItem);
}
}
catch
(Exception ex)
{
MessageBox.Show(ex.Message);
}
if
(listBox2.Items.Count > 0)
listBox2.SelectedIndex = 0;
listBox1.SelectedIndex =
listBox1.Items.Count - 1;
}
Remove All
private
void btnRemoveAll_Click(object sender, EventArgs e)
{
try
{
//moving all items from listbox2 to
listbox1
listBox1.Items.AddRange(listBox2.Items);
listBox2.Items.Clear();
}
