Plz change your fields to template mode first, and then handle GridView_RowUpdating, and then compare manually:
e.OldValues["fieldname"]
with
e.NewValues["fieldname"]
if equals, plz use：
e.Cancel = true;

How do you DataBind your GridView? Through a DataSource Control, or in code-behind?
If you are doing it in code-behind, what version of ASP.NET are you using? (4.0 is a lot more friendly than previous versions for this.)
Do you mean your entire GridView goes into Edit mode? Or just a single row at a time?
For an example on the use of the RowUpdating handler, see the msdn page for it.

protected void btnUpdate_Click(object sender, EventArgs e) { originalTable = (DataTable)ViewState["originalValues"]; foreach (GridViewRow row in GridView1.Rows) if(IsRowModified(row)) { GridView1.UpdateRow(row.RowIndex,false); } tableCopied = false; GridView1.DataBind(); }refer for more info http://csharpdotnetfreak.blogspot.com/2009/05/edit-multiple-records-gridview-checkbox.html
