Hi,

Whenever there is a postback, the gridview retrieves the data from the **Form Data**.  
I recommend you to modify the GridView in the form data itself by using the **FormData** object:

Example:

```auto
this.FormData.Tables["REQUEST_GRIDVIEW1"].Rows.Clear();
System.Data.DataRow newRow = this.FormData.Tables["REQUEST_GRIDVIEW1"].NewRow();
newRow[0] = "Value of 1st column";
newRow[1] = "Value of 2nd column";
newRow[2] = "Value of 3rd column";
this.FormData.Tables["REQUEST_GRIDVIEW1"].Rows.Add(newRow);
this.FormData.Tables["REQUEST_GRIDVIEW1"].AcceptChanges();
this.SaveFormData(this.FormData);
this.BindFormDataToFields(this.FormData);

```

Regards,  
Eddy.
