            chkListCategory.DisplayMember = "text";
            chkListCategory.ValueMember = "value";

Answer 1

I don’t know what is ListItem but I suppose it is a class that is looks like:

public class ListItem
{
    public string Text;
    public object Value;

    public ListItem(string text, object value)
    { /*...*/ }
}

So, change the DisplayMember = "text"; to "Text" and ValueMember = "value"; to "Value":

chkListCategory.DisplayMember = "Text";//"text"; 
chkListCategory.ValueMember = "Value";//"value";

The display text at UI will be “Manufacturer, Dealer, Distributor, …”

And the values will be “1, 2, 3, …”

Get the value member of checked items:

To get the values of checked items:

//first checked item.
var value = (chkListCategory.CheckedItems[0] as ListItem).Value;

//all checked items.
foreach (var value in chkListCategory.CheckedItems)
{
    Console.WriteLine((value as ListItem).Value);
}

//value at any index in the chkListCategory:
var value = (chkListCategory.Item[index] as ListItem).Value;
