Forms Data Controls :: Delete Multiple Lines In ListView With StoreProcedure?
Aug 9, 2010
I have a Listview which uses a StoredProcedure to display the data. That part works fine. What I'm trying to do is delete multiple lines using a different store procedure. So I did this code:
<asp:SqlDataSource ID="SqlDS_BasketDetails" runat="server"

I need you assistance, Dynamic Delete LinkButton with CommandName=Delete gives me an error: Delete can only be called on a valid data item. nfact I am designing a Complex Grid using .Net 3.5 ListView Control with Scrollbar and Fixed Toolbar: This grid consist of 3 Tables:
1- footer
2- Toolbar Control
3- Scrolling Data Grid with Header
ListView give us only one ItemPlaceHolder to Bind Data as per LayoutTemplate, so I cannot able to manupulate my Toolbar Controls with ItemTemplate :(, therefore I decide to use ItemDataBound to add ImageButtons Dynamically using Init Page Event and I am able to get the result as you saw above:
ImageButton with funnel icon is with CommandName="Filter"
ImageButton with magnifier icon is with CommandName="View"
ImageButton with stop icon is with CommandName="Delete"
Now I can able to handle Filter and View with OnItemCommand Event but when I click Delete button I am getting an error as shown below: The grid used CSS I am sending you the HTML and code behind to resolved this problem: HTML CODE:

Using code found here : [URL] .... I was wondering if the text could be formatted as in maintaining line feeds. I'm reading from an SQL 2008 database which has a text field. When I call it up the text format is gone. as an example I get :
what colour is the sun A:Green B:Red c:Yellow
instead of :
what colour is the sunA:Green B:Red c:Yellow

First time using a ListView control, I have it inside an UpdatePanel:
[Code]....
[Code]....
[Code]....
[Code]....
When the UpdatePanel Loads, it feeds the data to the ListView. Whenever the user clicks on a row in the ListView, a new window displaying a "note" pops up, the ItemDataBound event ties it all together. What I'm trying to do is add a button to each row so that the user can delete the row. This would call a Sql statement and then the row should disappear. I followed a couple of articles I found on ListView on how to do this, so I added a button called imgBtnDeleteNote (see markup above) and set the CommandName = "Delete", hoping that it would trigger the ItemCommand and ItemDeleting event (I have some bogus code in them, first I wanted to see if they would trigger).
The problem is that they don't seem to get triggered when I click on the delete button. All the rows in the listview disappear, and when I manually refresh the page they come back. My guess is that the events are not firing because I'm not using a DataSource object in the aspx code, but I'm not sure.

I keep getting Object Reference not set to an instance of an object errors when I try to use the ListView delete function. It is a fairly freshly created listview and is very close to the original template so not sure what is going wrong. Some possibly relevant code:
[Code]....
I also put in a breakpoint in the deleting event (only reason I added the deleting event) to look at the status of everything. When I do: Contact delContact = (Contact)e.Entity; and look at the values, the values for almost everything are set to null. It does have the correct value for the ID of the contact object that needs to be deleted. When I continue to step, it jumps to my designer.cs file and appears to break here:
[Code]....
likely because _Case_ID is null. The exact exception I'm encountering is: System.NullReferenceException: Object reference not set to an instance of an object. While I could probably re populate the object with correct values, that doesn't seem likely to address the real cause of the problem.

I'm new to Asp.net, and I looked at an example of using a listbox's selected index to delete from a sortedlist. I'd like to write somethingthat would get the selected index from a different control, like a listview, and then delete from the sortedlist. I've read up on a few examples on how to bind data from a sortedlist to a listview, but I've not seen an example of how to get the index once the data is displayed! Can this be done?

Within my ItemTemplate on a listview i have a link button carrying out a delete command. As it's a custom command i use the ItemCommand to do the deleting and have a stub itemdeleting.
It works fine set out like this however i only want the delete button to be available to logged in users. If i wrap the linkbutton in a loginview and then click on it the ItemCommand and ItemDeleting never get called the page just refreshes.

It should be simple, but I didn't found yet how to do it. There is only one user (Admin with user name and passowrd, he has a cookie so I know when he is watching the page) I would like to show him the Update/Delete/Insert button options in my ListView, but to the other users I don't want them to be able doing this kind of things, So it should be hidden from them. How I am doing it in C# code? Showing/Hiding these buttons?

I have a ListView in my system..
And inside it, there is a button called "Delete".
In the behind code, I tried to access the button control in the listview. However, the code keep looping non-stop..
The logic is the Delete button will only be visible by the current logged-in user. And I had already set the button as visible = false. I had set breakpoint to the line : Delete.Visible = true;. Once the execution reach here, it loop back to the first line again..
And Delete button remain invisble despite the execute visible = true statement..
Here is the code:
protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
{
MembershipUser currentUser = Membership.GetUser();
Guid currentUserId = (Guid)currentUser.ProviderUserKey;
[Code].....
