Updating datagridview

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.

Best regards, Jeffrey Tan Microsoft Online Community Support ================================================== When responding to posts, please "Reply to Group" via your newsreader so that others may learn and benefit from your issue.The STA model implies that a window can be created on any thread, but it cannot switch threads once created, and all function calls to it must occur on its creation thread. 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.

Add a Data Grid View control and two Buttons on a Form. This will be something like…(please check out code syntax) Integer i = Data Grid View1. Dynamic SQL generation for the Update Command is not supported against a Select Command that does not return any key column information………. my first form is datagridview …side buttons is.,edit, delete,and close…now i want add some details then click add button then open another form….insert the data from add form…add form close after inserted data…..i want automatic refresh the form1…… When you click add button , close the datagrid form, open up the add data form.

Is it possible to do the same things(insert,update,delete) with database in this Gridview. Thanx in advance :) Please have a look at this add Upadate Button_Click Event code.

Insert Delete Update in Data Grid View with Data Table in C Hello there, I have a lot of errors with the same announce for the following (some of them!!

I solve the "non-displaying" problem, but still have the "selection" problem. Thanks, -- George Hi Jeffrey, My code is similar to yours, with one exception. Hence, there is no interaction to the Data Grid View.

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!
