who is sandra lee dating - Datagridview updating database

In the third type of cases, on which are going to focus this article, you may need to update the data base right after the end-user finishes modifying a single value of Rad Grid View.

In order to be able to implement this functionality, you can handle the events of Rad Grid View or its Binding Source.

The Data Grid View can display data in Bound mode, unbound mode and Virtual mode .

Bound mode is suitable for managing data using automatic interaction with the data store.

To commit the data to the database in this case, we can use the private Data Row last Edit Row = null; public Auto Saving Data BSEvents Form() private void Auto Saving Data BSEvents Form_Load(object sender, Event Args e) void employees Binding Source_Current Changed(object sender, Event Args e) Private last Edit Row As Data Row = Nothing Public Sub New() Initialize Component() Add Handler Employees Binding Source.

Current Changed, Address Of employees Binding Source_Current Changed End Sub Private Sub Auto Saving Data BSEvents Form_Load(By Val sender As Object, By Val e As Event Args) ' TODO: This line of code loads data into the 'nwind Data Set.

I'd prefer to avoid the stupid column of integers like line numbers and just make my first text column the primary key, but when I try to do this and update the database, it throws errors.

If there's a way to do this, I'd appreciate the explanation of how, or if there's a way to hide the first line number column the pulls the integer value for the primary key, and have it automatically increment and/or adjust this value according to editing, changes and new rows being added that'd be great.

There's a few tutorials out there on this, but I'm assuming I must have implemented something wrong, because the code I followed from combined tutorials is not working as it should.

These are the tutorials: https://youtu.be/_i4m YXSa D4w , https://youtu.be/_s B0A6FIh UM I'm trying to create a Data Grid View that displays some basic data, just 4 columns of information.

In the following sample scenario we are going to demonstrate how the implementation can be achieved. NET Data Table that loads its data from a component is bound to Rad Grid View control.
