I work with VS2010 and we recently updated our Devart products to:
Devart dotConnect for Oracle 6.60.258.0
Devart Entity Developer 4.2.85.0
Devart OraDeveloper Tools 2.60
Since the upgrade, my comboBoxen don't work anymore.
I used to use them as follows:
Code: Select all
SelectedValuePath="ID"
SelectedValue="{Binding Path=GESL_ID}"
The error comes from datasetDesigner.cs:
Code: Select all
set
{
if (this._GESL_ID != value)
{
if (this._CT_RELA_GESLACHTEN.HasLoadedOrAssignedValue)
{
throw new System.Data.Linq.ForeignKeyReferenceAlreadyHasValueException();
}
Code: Select all
SelectedItem="{Binding Path=CT_RELA_GESLACHTEN}"
What I don't understand is why this happens now?
And do I have to change ALL MY comboboxen ?
Thank you for looking at this problem,
