Steps to Reproduce Behavior
This code uses the Biblio database that comes with Visual Basic.
- Start Visual Basic 6.0 and create a new EXE project. Form1 is added by default.
Add the following two controls to the default form:
Microsoft ADO Data Control 6.0 (OLEDB) Microsoft DataGrid Control 6.0 (OLEDB)
Set the properties of the ADO Data Control, ADODC1, as follows:
ConnectionString Provider=Microsoft.Jet.OLEDB.3.51;DataSource= C:\ProgramFiles\Microsoft Visual Studio\VB98\Biblio.mdb RecordSource "SELECT * FROM Authors"
Set the properties of the DataGrid, DataGrid1, as follows:
DataSource ADODC1 AllowAddNew True TabAction 2-dbgGridNavigation
Add following code to the default form:
Private Sub DataGrid1_OnAddNew() DataGrid1.Columns("Author").Text = "Test" DataGrid1.Columns("Year Born").Text = 1996 End Sub
- Run the project. Go to the last record in the DataGrid (the blank row) and click on any cell. The second and third columns will have the default values "Test" and "1999" entered. Continue tabbing through the cells so that the new record gets updated.
- End the program , and then run again. Note that the new row has not actually been added.
