Datagrid issue

[laloush83]

I have a datagrid and a label, the datagrid have three columns, one of these columns is numeric.. when the form loads the datagrid is empty and the label text is set to 0 .. every time I add a new row to the datagrid and enter a number in the numeric column .. this number should be added to the amount existing in the label.text ... how can I do that?

I assume it will be changing an underlying table....

dim i as integer
i += convert.toint32(Tablename.Rows(rowindex).Item(columnName))
label.text = convert.tostring(i)

Yes but Where should I write this code?
this code should be executed only when I insert a new row int the dataGrid??

Best thing to do is have a look and see what events the table raises. It may for example.. Raise a 'Column Changing' event which would mean that you could put that code in there.
