Default Add/Edit Flow question

My question should be fairly simple I believe but just wanted a few opinions or how you managed the flow.

When you update an item from an add/edit page and click update or even cancel for that matter the automated routines bring you back to a new item entry screen. To me it would make more sense to go back to the listing screen where I selected the item to be edited in the first place.

My questions are:
Is the a parameter or redirect I can insert which still allows the update to occur and return me to my list page?

Does anybody else see this as an issue?

Thanks,
J

I am referring to the admin of like products or articles. You select a product to edit. You change the price or some other field and click update. The next screen is to enter a new item into the product list. It just doesn't seem to me to be a normal flow. I would like to be returned to the list or even a confirmation that the update was successful but I don't think after an update the next logical place to go would be to add a new item.

Even more strange is the when clicking Cancel it returns me to a new item entry screen instead of where we came from.

Thanks,
J

ummmmm I see!

I gave it a look...

Add this to your addeditarticle code behind:
Code:
        Protected Sub objCurrArticle_Inserted(ByVal sender As Object, _ 
                ByVal e As System.Web.UI.WebControls.ObjectDataSourceStatusEventArgs) _ 
                Handles objCurrArticle.Inserted
            Response.Redirect("ManageArticles.aspx")
        End Sub


You can do by your own the same on product page.
Find the objectdatasource that do the "product insert" and make a function like the one that I gave you for articles!

p.s. This only work for new articles inserted. If you want the same for article updated use the same code with the difference = ...objCurrArticle_Updated...

feel free to post some doubt if you have some!

Thank you many times over, you are good.

It was not exactly the answer I looking for as I code in C# but it sent me down the right path and it is flowing as I like.

I will post my final code changes for reference. As you can see I am not using Articles or Products but Parts Maintenance is actually part of my application.

So in my PartsAddEdit.aspx I modified the following line of code by adding the highlighted.

   <asp:DetailsView ID="dvwPart" runat="server" AutoGenerateDeleteButton="True" AutoGenerateEditButton="True"
      AutoGenerateInsertButton="True" AutoGenerateRows="False" DataKeyNames="PartID" DataSourceID="objCurrPart"
      DefaultMode="Insert" HeaderText="Part Details" OnItemCreated="dvwPart_ItemCreated" OnItemUpdated="dvwPart_OnItemUpdated"
      OnItemInserted="dvwPart_OnItemInserted" OnDataBound="dvwPart_DataBound" OnModeChanged="dvwPart_ModeChanged">

And in my PartsAddEdit.aspx.cs I added the following lines of code.
        protected void dvwPart_OnItemUpdated(object sender, EventArgs e)
        {
            Response.Redirect("ManageParts.aspx");
        }

        protected void dvwPart_OnItemInserted(object sender, EventArgs e)
        {
            Response.Redirect("ManageParts.aspx");
        }


Thanks,
J

I'm glad you make it!

You don't need to add the green lines to your detailsView IF you add the "Handles xxxxx.Inserted" on your code behind.

But this might confuse you...
Your version work too, but in this way you need to change the aspx and the code behind.
I don't know if you know that:
In Visual Studio open your cs file.
You have two dropdown lists on the top. General at left and declarations on right.
If you select you datasource/details view from you "general" dropdown, then select the event that you want (Inserted... Updated... etc)
When you do that, the cs file generate the "handles" for your control!
I mean: Asp.Net will be watching for this event!

But if this strange fro you, use your way, because it works too!

Thanks for post the C version!
