C datagridview bound to datatable not updating irishsingledating com

Hi, I have been encountering a refresh problem with Data Grid View, which is bound to a Data Table.

When I make updates (Add, Delete, update) to the Data Grid View, everything flow nicely to Data Table. However, when I add data (programatically) to the Data Table, the Data Grid View does not refresh right away.

Here is the relevant setup code - in the properties dialog (and set explicitly in the code).

The initial columns were generated programmatically and so should not have appeared however this was not picked up on since the designer code also continued to generate 'designed in' columns that were originally used for debugging. In addition to this, see this post and this post it binds the table to the Data Grid View.

I no longer needs to manually refresh or Reset Bindings the Data Grid View. When it comes to driving traffic to your site, one of the easiest, and cheapest ways to do this is through social media.Net Winform databinding code will try to update the new row into the Data Grid View UI. Net Windows Forms uses the single-threaded apartment (STA) model because Windows Forms is based on native Win32 windows that are inherently apartment-threaded.

Comment: Wrapping these calls become very cumbersome, and potentially a bottle neck since UI thread may be bogged down by work. ================================================== This posting is provided "AS IS" with no warranties, and confers no rights Hi George, Thanks for your feedback! Yes, read-only manipulation to the GUI thread also needs to be wrapped with Control. Let's suppose a control is still updating its state while you are retrieving its state, you may get an immediate partial updated state which may appear to be incorrect. To wrap these methods or properties calling, you may write a method(let's call it Wrap Method() ) in Form class which contains all these code, then in File System Watcher thread, you can just marshal once calling to the Wrap Method(), not marshal to all the code statements. Net Winform code, it is caused by the native Win32 standard controls. ================================================== This posting is provided "AS IS" with no warranties, and confers no rights.
