Hi all,i m really stuck up with this problem
I am creating c# desktop application for inventory management.
In one of the forms I want to display datagridview with three columns.(sr.no,product_name,invoice_no)
1)sr.no is checkbox column which checks product.
2)Product_name is column which displays name of product
3)invoice_no is COMBOBOX columns which selects one of the invoice no in which that checked product is sold.
My problem is when i select the value for invioce_no(combobox) in first row and after that when i move to the next row the selected value of invioce_no(combobox) in first row disappears .and throws exception DataGridViewComboBoxCell value is not valid.
plz help me in resolving this error,I really need a solution to this problem.
