protected void GridView1_RowDeleting(object sender, System.Web.UI.WebControls.GridViewDeleteEventArgs e) {
    }

and make sure you gridview has the following
onrowdeleting="GridView1_RowDeleting"

Ok I think you are correct but I am having an issue that is preventing me from testing it out,,,


When I try to do the delete it provides the following error

Deleting is not supported by data source 'SqlDataSource1' unless DeleteCommand is specified.

Which is pretty understandable error for me the only problem is is when I go to the 'SqlDataSource1' and choose "Configure Data Source" when I attempt to add "Update, Delete" functionality to it it is just greyed out.

The SQL statment for that 'SqlDataSource1' is a simple select

Ok disregard the last statement I just figured out that in order for those options to be available you have to have a primary key set to the table

Aight now I tested out what I have but it does not work
 though I do not understand fully your reply on this can you be a bit more descriptive

This is what I have



    void GridView1_RowDeleting(Object sender, GridViewDeleteEventArgs e)
    {

        // Cancel the delete operation if the user attempts to remove
        // the last record from the GridView control.
        if (GridView1.Rows.Count <= 1)
        {
            Response.Write("I Hope this works");
        }

    }  

But what are you talking about in regards to the onrowdeleting="GridView1_RowDeleting"

ok Now I figured out what you were talking about regarding onrowdeleting but this is what I get now

Error      1      No overload for 'GridView1_RowDeleting' matches delegate 'System.Web.UI.WebControls.GridViewDeletedEventHandler'      C:\Documents and Settings\Scott\My Documents\Visual Studio 2005\WebSites\shotdrive\upload.aspx      18

This is my code

        <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True"
            AutoGenerateColumns="False" CellPadding="4" DataSourceID="SqlDataSource1" ForeColor="#333333"
            GridLines="None" Style="z-index: 103; left: 160px; position: absolute; top: 204px" OnRowDeleted="GridView1_RowDeleting" >



    protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
    }

Ok I figured out that I was using OnRowDeleted when I should have been using OnRowDeleting

But I still have the problem that it is not deleting any rows

Figured it all out I was just missing

DataKeyNames="ID" in the GridView. I didnt even have to add the primary key to the Gridview to show. although for future readers of this as to not confuse  the Primary Key does have to be included in the SQLDataSource in order for it to work.
 

Thank you to everyone that helped with this

Dear,
Don't use delete keyword, try to use another keyword just like "Remove". Because the delete keyword is a reserved keyword in 'SqlDataSource1'
Just like :
<ItemTemplate>
<asp:LinkButton ID="LinkButton23" runat="server" CausesValidation="False" CommandName="Remove" Text="Remove"></asp:LinkButton>
</ItemTemplate>
You can use commandArgument keyword to delete selected row from gridview
as                       CommandArgument = '<%# Eval("Name of the Your Field") %>'
then in item command
if e.commandargument = "Remove";
call function or sub for deleting the row from the datagrid
 YouFunction(E.CommandArgument)
