Databinding - How To Delete An Item In .NET Listview And Persist The Datasource

Apr 27, 2010

I have a collection of objects I bind to a Listview like this:

if (!IsPostBack)
List<Equipment> persons = new List<Equipment>
{new Equipment{ItemName = "Sworn", ItemCount = 7, ItemCost = 255}, [code]....

I want to Add/update/delete from this object collection and submit the final data object collection to the BL when the user saves... Rather than just delete/add/update everytime a row is changed.So my question is how do I maintain state for that datasource? I have tried this (delete example)

protected void lvMain_ItemCommand(object sender, ListViewCommandEventArgs e)
switch (e.CommandName)
case "Delete":

But it does nothing. I can't rebind it to the datasrouce because at this point the datasource is null.. I assume the listview keeps its own view state which contains the data?... I guess worse case I can always hold the Object Collection in a Session object.. ..

Forms Data Controls :: Dynamic Delete LinkButton In ListView Error "Delete Can Only Be Called On A Valid Data Item"

Feb 22, 2010

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:

Forms Data Controls :: Delete Row From ListView With No DataSource?

Apr 28, 2010

First time using a ListView control, I have it inside an UpdatePanel:





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.

How To Access The Bound DataSource Item In The ListView's DataBound Event

Sep 22, 2010

I know the question has already been posted here but we didn't get to an real solution.I have bound my ListView to an SqlDataSource and I want to write some text in a control present in the view created in the LayoutTemplate depending on some properties of the rows returned.Obviously, I'm using the ItemDataBound event to feed my items but this is not the point.

The spontaneous solution was to bind the ListView.DataBound event and access the raw datasource (a DataTable?) and do the required calculations.I inspected the Items property and, despite it was not empty, the related DataItem property was null.The only work-around I can come to is to execute the calculations in the ItemDataBound event and accumulate the result in some private fields. But it's really ugly to see and makes harder to get some of the required values.

Forms Data Controls :: Validating Page With Listview Edit Item And Insert Item Templates Are Both Present

Aug 9, 2010

I have a listview set up in "flow" mode where the existing records are all on an extended page so you can scroll down to any record.

The InsertItem Template is in the first position, making it easy to insert a new record.

And one can scroll down the page to any record, click the edit button and update that record -- nice having everything on one scrollable page.

I am running into a problem with validations. I have validation controls restricting inputs for all the textboxes on the Insert Item template. They work fine. And on Item Inserted I am running a page validation:

If Not Page.IsValid Then
e.Cancel = True
End If

which works fine also.

The problem occurs when I scroll down to an existing record, and go to edit it. I have all the same validation constraints on the textboxes for the EditItemTemplate as I have on the InsertItemTemplate. But I cannot successfully do a page validation on updating the record. The code I am using on update is:

Protected Sub LVRentals_ItemUpdating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewUpdateEventArgs) Handles LVRentals.ItemUpdating
If Not Page.IsValid Then
e.Cancel = True
End If
End Sub

This results in a Cancel even if there are no validation errors on the InsertItemTemplate because the Page.Validate() seems to be causing the InsertItemTemplate to think its fields should be filled out also.

Here is the code for a typical entry of the InsertItem Template:


All the controls in the Edit Item template are part of ValidationGroup "edit1" and those of the InsertItem Template are part of ValidationGroup "edit2"

How can I get around receiving validation errors on the InsertItem Template when I am trying to validate just the EditItemTemplate when both are present on the page?

C# - Bind The Datasource Of A Nested ListView To The Parent's ListView Datasource?

Dec 13, 2010

I have triple-nested ListView controls on my page, each nested within another. I use the OnItemDataBound event in the 1st ListView to set the DataSource of the 2nd level ListView. The 3rd ListView is contained in the of the 2nd ListView. I want to assign the same DataSource to both the 2nd and 3rd level ListView datasource controls, but I cannot figure out how to access the 3rd level ListView in order to do that.


The level1_ItemDataBound method finds the level2 control, casts it as a ListView, sets its DataSource and executes the DataBind. At this point I'm stuck trying to get Level3.DataSource to be set to the same as Level2.DataSource.

AJAX :: UpdatePanel - GridView - DataSource Null - Get The Datatable To Persist Between The Two Update Panels?

Jan 17, 2010

I am going to outline my setup then where i am failing

UpdatePanel1 - Contents : 3 textboxes and AddButton
UpdatePanel2 - Contents : 1 GridView and SubmitButton

AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page

DataSource Controls :: Programmatically Databinding Treeview Vs Sitemapdatasource

Nov 12, 2010

somewhere on the net I found very useful example of programatically databainding the treeview control (code blow). I use this treeview as menu bar in my masterpage. It works fine but with one exception: when I click the node of this treeview I'm redirected to the correct page but after page is reloaded my treeview is collapsed and node I chose just before is not highlighted. What to do to correct this problem. Do you know better examples of programatically databainding of the treeview control? Maybe it will be better to bind data to the sitemapdatasource and next to the treeview. Then I shouldn't have to worried about this?

Forms Data Controls :: ListView Delete And Object Reference Not Set

Feb 18, 2011

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:


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:


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.
