I'm having some difficulty in trying to save/cancel record inserts with an ASPxGridView containing an ASPxPageControl in the EditForm.
The EditForm contains a TextBox, a ComboBox, an UploadControl (with a couple extra buttons to upload and clear the image), and a PageControl containing two pages, each of which contains 12 sets of CheckBox and TextBox (24 CheckBoxes and 24 TextBoxes in all).
The EditForm is a popup. I have a custom Save and Cancel button at the top of the form that calls a JS function to UpdateEdit() or CancelEdit().
When I press either one of the Save/Cancel buttons, I get a "null reference" error on the first bound control in the PageControl (specifically, it's a CheckBox). The debugger goes directly to the HTML code and the control, rather than stopping on any CS code. I can't tell where the error is happening.
Can you please shed some light on this problem? I've attached my entire project. It connects to a public database. Use "demo" as the username and password. When you come to the main screen, click the "Admin" button on the bottom-left. Then, go to the "Customers" tab. Editing seems to work fine. But, adding a record doesn't work.
Thanks,

Hello Kevin,
>>When you come to the main screen, click the "Admin" button on the bottom-left. Then, go to the "Customers" tab.
Unfortunately, I do not see the ASPxGridView in the "Customers" tab. However, I've get an issue with the grid in the AgentsTabPage tab. To overcome it, please change the Bind expression as shown below:
Old code: Text='<%# Bind(AGENTCODE) %>' > New code: Text='<%# Bind("[AGENTCODE]") %>' >Attached is a modified project.
By the way, I suggest you catch the exception by adjusting the VS as shown below. In most cases, this approach helps find the cause of exceptions.
Thanks,
Marion
