C datagridview bound to datatable not updating

23-Dec-2019 02:13

The Table Adapter Manager class ensures that updates are made in the correct order based on the foreign-key constraints that are defined in the database.When you use data-bound controls, the databinding architecture creates a member variable of the Table Adapter Manager class called table Adapter Manager.I have attached my sample project in this reply for your reference. ================================================== This posting is provided "AS IS" with no warranties, and confers no rights Hi George, Thanks for your feedback information!Yes, I think your background information is critical regarding resolving your problem. Comment: Wrapping these calls become very cumbersome, and potentially a bottle neck since UI thread may be bogged down by work.Also see How to: Bind Data to the Windows Forms Data Grid View Control Using the Designer. Run(New Form1()) End Sub ' Initialize the form.

If you aren't using data-bound controls, then you have to manually call the Update method of the same Table Adapter (or data adapter) that you used to populate the dataset.

Please see if there is a newer thread on the subject and ensure you're using the most recent build of any software if your question regards a particular product. 11, 2013 nightly build and we found the following problem: 1) Binding the Data Grid with Data Table.

Default View 2) A work thread is updating the Data Table 3) For the existing rows, if any cell value changed, it will update, which is good.

I also notice that, as soon as I delete or cell-update a row, all these problems go away. I suspect the "in-activity" is causing the refresh problem. As soon as I "interactively" delete a row, everything is fine. Thanks, -- George ""Jeffrey Tan[MSFT]"" wrote: Hi George, Thanks for your post!

I have written a sample project regarding your scenario, however, it works well on my side: Data Table dt; private void Form1_Load(object sender, Event Args e) private void button1_Click(object sender, Event Args e) When I clicked Button1 to add a new row to the Data Table, the Data Grid View refresh the update immediately.
