I need to know how to edit a asp.net gridview row when it has been uploaded from an excel spreadsheet but has not been saved to a SQL database. I want to give the option to the user to edit and delete rows in the gridview table after they have uploaded the table from excel file before they submit the gridview to the SQL database.
Please help.
Thank you,

For each of your ItemTemplate tags in the gridview, add an EdittItemTemplate tag.  And then add a column with the edit and delete buttons.  For example:

<ItemTemplate>
     <tr>
        <td><%# Eval("FirstName") %></td>
     </tr>
</ItemTemplate>
 <EditItemTemplate>
      <tr>
        <td><asp:TextBox runat="server" ID="txtFirstName" CssClass="text" style="width:76px;" MaxLength="50" Text='<%# Eval("FirstName") %>'/></td>
     </tr>
</EditItemTemplate>
<asp:CommandField ButtonType="Link" ShowEditButton="true" ShowDeleteButton="true" ItemStyle-Width="150"/>

you can try providing  a popup  for editing row values, showing the selected row for edit on edit click,
on the row command event  get the id of the row Or the record, get the latest changes provided by the user and update the same in datatable or dataset and again rebind the grid.

hope this helps.
