My problem is about insert value from textbox of gridview to sql server.

    1. COGrid view shows you the stored data from sql. So you can't insert from grid view, I mean of course you can insert but this is not a proper way. So you should just update the fields.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
