sql update via gridview

check the binding of grid ... also check in code whether you are passing correct data to update ... one more thing .. did you gridview contain datakesyname .... if not set it first
also paste your code here ...

my code is:

my code is

protected void edit_record_updating(object sender, GridViewUpdateEventArgs e)
    {
       
        update_class update_records_method = new update_class();
        update_records_method.Record_ID = ((TextBox)user_records.Rows[e.RowIndex].Cells[2].Controls[0]).Text.ToString();
        update_records_method.Logon_Name = WindowsIdentity.GetCurrent().Name.ToString();
        update_records_method.Record_Class = ((TextBox)user_records.Rows[e.RowIndex].Cells[4].Controls[0]).Text.ToString();  
        update_records_method.Record_Name = ((TextBox)user_records.Rows[e.RowIndex].Cells[6].Controls[0]).Text.ToString();
}

I did not use andy datakeyname as I am not sure how to use this property.

in your case its not require (datakeys)
are you getting this record correct
 update_records_method.Record_ID = ((TextBox)user_records.Rows[e.RowIndex].Cells[2].Controls[0]).Text.ToString();

also what problem you are getting in update ...

I have tested my code using break points and I have concluded that the following;

When I click the Edit button on the gridview TextBoxes appear to allow me to edit the content.
When I click the Update button the code does not recognise that the TextBoxes have been updated and no change is made.

I have tested the code with other virables which works successfully (i.e new values are inserted and appear in the gridview). There is something wrong with the way i am picking up the editted values from the gridview.
