Protected Sub Object Data Source1_Inserting _ (sender As Object, e As Object Data Source Method Event Args) _ Handles Object Data Source1. In this tutorial we examined the pre-level events and saw how to use these to customize the input parameters or cancel the data modification operation altogether both from the data Web control and Object Data Source's events.
In a real-world application you would likely want to either let the user specify the category and supplier or would pick this value for them based on some criteria or business logic (rather than blindly selecting an ID of 1). Input Parameters("Supplier ID") = 1 End Sub V tomto kurzu jsme zkontrolován předem úroveň události a viděli, jak tyto slouží k přizpůsobení vstupní parametry nebo zrušit operace změny dat z ovládací prvek webu data a události na Object Data Source zcela i.
But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.
When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.
Update(product) Return rows Affected = 1 End Function Protected Sub Grid View1_Row Updating(sender As Object, e As Grid View Update Event Args) _ Handles Grid View1.
Value End If Dim rows Affected As Integer = Adapter.
Check out what I’m trying to do, maybe you can help?
First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.
Because we are not using the Grid View’s built-in data model and are binding dynamically, the Grid View will not switch into and out of Edit Mode automatically.
Everything should be sorted out when the “Update” link is pressed.
Finally, to pull your hidden value that you’ve dubbed a Data Key in the Grid View’s subroutine.
Row Updating event, doesn’t work as all samples say it should do.
All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.
Thus, in order to switch it into Edit Mode, in each of your event handles (Row Editing, Row Updating, and Row Canceling Edit) you must do two things: Protected Sub Grid View1_Row Editing(By Val sender As System.
