Hi,
I have an app that succesfully populates a combobox with a list of countries using a dataset and setting the .datasource and .displaymember properties.
I have now set that combo box to be databound to a SQL Server table using:
myCombo.DataBindings.Add("SelectedValue", dsMyDataSet.Tables(0), "fieldName")
This works okay but if the record I'm editing/viewing has a NULL value for "fieldName" then I get the following useful message:
"Additional information: Can't set the SelectedValue in a ListControl with empty ValueMember."
I understand teh problem but how do deal with blank/null fields that are bound to combo/list boxes?
All help appreciated.
Thanks
Andrew
