checkbox list DataTextField...

I have a checkbox list and need to add the DataTextField from a dataTable how to I add the column names to the Checkbox List DataTextField control?
 // Iterate through your values  foreach (DataColumn dc in dt.Columns) {       chkShowHideCol.DataTextField = dc.ColumnName;  <-- I need to add the column name for the datafield and valuefield.        chkShowHideCol.DataValueField = dc.ColumnName;  }  chkShowHideCol.DataSource = dt;  chkShowHideCol.DataBind();
