Data are missing after updating

Okay I'll discuss my problem with images so we can solve it easily. Hoping.

First, The image below shows the PersonalInfo gridview under PersonalInfo.aspx

Second, The image below shows the MobileInfo gridview under MobileINfo.aspx

Third, now we are going to edit the record in this page MobileInfo.aspx

Fourth, Image below I thought everything works perfectly because the data has been updated. But...

Fifth and last, I went back in PersonalInfo.aspx but it gives me this...Data has been deleted

Here's my code for PersonalInfo.aspx

<asp:AccessDataSource runat="server" ID="AccessDataSource1" DeleteCommand="DELETE FROM [DriversRecords] WHERE [ID] = ?" InsertCommand="INSERT INTO [DriversRecords] ([Username], [Password], [FirstName], [LastName], [MiddleName], [Address], [Age], [Gender], [ContactNumber], [PlateNumber], [Color], [Brand], [LiscensedNumber], [SSSNumber], [TIN], [Type], [Model], [BirthDay], [BirthMonth], [BirthYear]) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)"

I hope someone can help me here. Thanks.

What I see here is that you have the same UpdateCommand on the two pages, but on the second page that you make the update, the values are all null or not exist and the result is that you actually deletes them.

Go on this UpdateCommand of the page MobileINfo.aspx and remove the field that you do not actually use - keep only the one that you actually change them - or the rest are refereed to data that not exist and there fore they are delete.

UpdateCommand="UPDATE [DriversRecords] SET [Username] = ?, [Password] = ?, [FirstName] = ?, [LastName] = ?, [MiddleName] = ?, [Address] = ?, [Age] = ?, [Gender] = ?, [ContactNumber] = ?, [PlateNumber] = ?, [Color] = ?, [Brand] = ?, [LiscensedNumber] = ?, [SSSNumber] = ?, [TIN] = ?, [Type] = ?, [Model] = ?, [BirthDay] = ?, [BirthMonth] = ?, [BirthYear] = ? WHERE [ID] = ?"

Eg, on the second page the LiscensedNumber exit, but the Gender not. After your update the Gender will update to null, or empty string.
