Well, we always have a reason so I believe it is not working because Selected Value only has a Get (it’s read only) and the value can not be put back.So, the solution that works for me is to program the Grid View’s Updating Row Event.You can use this control in Windows Form using Wizard or programmatically. Select the components you want to reference, and then click OK. But unfortunately when i debugging this code an error is coming ” System.

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.
