I have a parent frame when I give the new button, I open its child frame that has text boxes and a save button, what I want is that when you fill my text boxes my data will be shown in my datagridview of my parent frame , hopefully you can help me please.
Assuming you have a 1.aspx page that contains an iframe that shows page 2.aspx
in 2.aspx you can put
<a href="1.aspx" target="_parent">Actualizar todo</a>
This way the main page is reloaded (1.aspx)
NOTE: The next time you publish your code, it is much easier to understand us by looking at the code.
