ASP.NET CheckBoxList DataBinding Question

Question

Is it possible to DataBind an ASP.NET CheckBoxList such that a string value in the data becomes the label of the check box and a bool value checks/unchecks the box?

Answer 1

It's not possible using markup. What you can do is to bind the checkboxlist like you wanted it to work - with the bool in the DataValueField, and then simply add this as OnDataBound event.

protected void myCheckBoxList_DataBound(object sender, EventArgs e)
    {
        foreach (ListItem item in myCheckBoxList.Items)
        {
            item.Selected = bool.Parse(item.Value);
        }
    }

The difference between this solution and the one proposed by Jose Basilio is that this one works with all kind of databinding methods. For example binding with a SelectMethod using the new ModelBinding feature in v4.5.
