how to check only one item in checkedlistbox
- by Shashi Jaiswal
I have check list box control and i want to select only one item at a time and i am currently using this code to do the same.
private void CLSTVariable_ItemCheck(object sender, ItemCheckEventArgs e)
{
// Local variable
int ListIndex;
CLSTVariable.ItemCheck -= CLSTVariable_ItemCheck;
for (ListIndex = 0;
ListIndex < CLSTVariable.Items.Count;
ListIndex++)
{
// Unchecked all items that is not currently selected
if (CLSTVariable.SelectedIndex != ListIndex)
{
// set item as unchecked
CLSTVariable.SetItemChecked(ListIndex, false);
} // if
else
{
// set selected item as checked
CLSTVariable.SetItemChecked(ListIndex, true);
}
} // for
CLSTVariable.ItemCheck += CLSTVariable_ItemCheck;
}
this code is working fine.
but problem is that when i click again and again on selected item then that selected item should not be unchecked, means at least one item should be checked always...
