ASP.Net FormView 不会使用 Response.Redirect 代码更新

Question

I have a fairly simple FormView control I'm using with ASP.Net/C#. My issue is when I use the code to redirect after the update/edit, the FormView won't actually perform the update, but, it will Redirect. I won't post all of the FormView code because it does update when I comment out the Redirect code. I think what I am asking is how to change the code to update while using the Redirect Code? Again, the update works fine when I don't do the Redirect! Is it possible the redirect is happening before the update can take place?

Code for Redirect

         <script runat="server">

    protected void FormView1_ItemUpdating(Object sender, FormViewUpdateEventArgs e)
    {
       
        {
           Response.Redirect("redirect_main.aspx");
        }
    }


</script>

FormView1
          <asp:FormView ID="FormView1" runat="server" onitemupdating="FormView1_ItemUpdating" DataKeyNames="req_submitted_key" DataSourceID="SqlDataSource2" DefaultMode="Edit" >

Yes...it redirecting before the update. Take your redirect out of ItemUpdating and put it in ItemUpdated.

From: DetailsView.ItemUpdatint Event

DetailsView.ItemUpdating Event

Occurs when an Update button within a DetailsView control is clicked, but before the update operation.

DetailsView.ItemUpdated Event

Occurs when an Update button within a DetailsView control is clicked, but after the update operation.

DetailsView.ItemUpdated Event

Your code should look like:

protected void FormView1_ItemUpdated(Object sender, FormViewUpdateEventArgs e)
{
    Response.Redirect("redirect_main.aspx");
}
