Symptoms
When you delete the table that is bound to a control form of the DataSet Schema and then save the project in Microsoft Visual Studio .NET, you may receive the following error message when you open the form in Design view:

Can’t create a child list for field TableName.
The controls that are added before the data bound control are deleted from the form by Visual Studio .NET, and you receive the following error message in the data bound control:

System.ArgumentException: Can’t create a child list for field TableName.
Resolution
In Windows Form Designer-generated code, the controls are displayed on the form when the Control array is added to the Controls collection of the form. The last control that is added to the form has the index 0 in the Control array, the first control has the highest index, and then the other controls. When the XML Schema is changed, the data bound control raises an error and the controls that were added to the form before the data bound control are removed from the array because the controls are after the data bound control in the Control array. Therefore, the controls are not added to the Controls collection of the form and are not displayed.
