Updating database from datagridview vb net

As you saw in the Data Table, Data Row, and Data Column sections at the beginning of this article, you can use the Delete method of a Data Row to delete a row.

The Add New method of the Data Table adds a row to a Data Table.

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.

One Button is for deleting the selected row and other one is for updating or inserting new row. When i click update button i got this exception can u tell me why??? i am using form1 obj=new form1(); obj.refresh(); but it is not work…. Now, when you close the add data form, open the datagrid form again automatically.

For example, if you call Delete on a row on the Data Set, then when Update is called on the Data Adapter, the Delete Command of the Data Adapter will be called using the particular row in the Data Set.

I also had the problem of errors occuring when i altered the primary key of a line in the dataset. For this, i used where condition in the query and left the rest of the code as before(similar to urs). But now i want to take a data Grid View where i will add 3 column(name,address, Phone) manualy.

  1. I’m trying to convince a single friend who has lived in Turkey for two years to let me document her hilarious (and sometimes scary) Tinder adventures, which include one man calling her a “prostitute” after she told him she is posing nude for an artist. In terms of sexual politics, Turks veer much closer to the ‘conservative’ dial than the ‘liberal’ one.
