CheckedListBox (chlb)

CheckedListBox - Allows the user to select multiple items from a list of items.

This control inherits from the ListBox control and therefore has the same properties, methods and events.
You should change the CheckOnClick property to True to let the user check and uncheck elements with a single click.
The checkboxes can be in three possible states (similar to a Checkbox control).
You can only click on a checkbox to select or clear it, the indeterminate state can only be set from code.

To add objects to the list at run time, assign an array of object references with the AddRange method.
If UseTabStops is true, the CheckedListBox will recognize and expand tab characters in an item's text, creating columns. However, the tab stops are preset and cannot be changed.

The default font is Microsoft Sans Serif 8.25 which can distort the text
This should be changed to font size 8 ???

Multiple Selection

This control does not support selecting multiple items at the same time so the SelectionMode controls whether to select a single item or no items
This control lets you check multiple items but only by selecting each one individually.

Examples

Useful Code

This will change an item so it is selected

this.CheckedListBox1.SetItemChecked(ichartcount, true); 

This will change an item so it is NOT selected

this.CheckedListBox1.SetItemChecked(ichartcount, false); 

The SelectedItems and SelectedIndices collections have been replaced by the CheckedItems and CheckedIndices collections respectively.

for (int icount = 0; icount < objCheckedListBox.CheckedItems.Count; icount++) 
{ 
   sreturn = sreturn & objCheckedListBox.CheckedItems(icount).ToString(); 
}
