Miscellaneous questions about multiselectioncombobox

Question

Good Morning,

We are trying to use the MultiSelectionComboBox control and we would like to know how to make a button that selects all the elements and another that deselects them.

We would also like to know if it is possible to assign a value to each item.

We are using the Windows Form controls over vb.net.

Thank you.

A greeting.

Good Morning,

Thanks for your quick response. I have checked the source code that I have attached.

I have not been able to loop to get all the values ​​of the selected items.

Your code only allows me to select a value and not all that is what I need.

How can I do it?

Thank you.

RegardsEdit: if enabled the check box is not marked with Me.multiSelectionComboBox1.SelectAll ()
