here is the code for the delete button

    private void btnDelete_Click(object sender, EventArgs e)
    {
        for (int i = clbSummary.CheckedIndices.Count - 1; i >= 0; --i)
        {

Why don't you do remove the item from the list within the btnDelete_Click method.

For example:

private void btnDelete_Click(object sender, EventArgs e)
{
    for (int i = clbSummary.CheckedIndices.Count - 1; i >= 0; --i)
    {
        object item = clbSummary.Items[clbSummary.CheckedIndices[i]];
        myList = myList.Remove(item);
        clbSummary.Items.RemoveAt(clbSummary.CheckedIndices[i]);


    }

}

I'm not sure if you can use the [] operator on Items, but this is to give you a general idea.

Set the checklistbox DataSource property to the list where you are storing the items. When you make any changes to the list, your checklistbox will update.
