New Post: CheckComboBox Binding Data

Please post a code snippet on how to bind data to this checkedcomb box. I find it difficult to understand how to pass two data valus, one containing the total Items and the other containing selected items of these.

I tried the following and it worked but I just want to bind a single data source.

1. I set
   cmbBox.Itemsource=listOfItems;
   
2. I added the items to be selected to the SelectedItems property using a foreach loop. And these items are also added in the
   foreach(string str in LstSelectedItems)
   cmbBox.SelectedItems.Add(str);
   

But there should be a better option right??
