Vb.net - Listview Concatenate Data Items In Code Behind?
Feb 10, 2011
I have a listview with some data bound to it.
In this data are column for an address.
How would I go about accessing these data items in code behind so I can concatenate them into one easy variable and miss out columns that have no data in, i have fields:
address
address1
town
county
postcode
I don't have a problem with the concatenation just accessing the data items.
I am getting data out via a dataset and binding it to a listview.
Is it possible to access data items in the code behind to format or do whatever i want with them then showing it in the list view such as, concatenating the address fields into one variable?
so instead of writing:
DataBinder.Eval(Container.DataItem, "address") & ", " & DataBinder.Eval(Container.DataItem, "address1") & ", " & DataBinder.Eval(Container.DataItem, "town") etc...
in the actual list view i could do this in the code behind in a string variable then show the variable in the list view?
'select command
Dim cmdSchedule As SqlCommand = New SqlCommand()
cmdSchedule.Connection = keypadSQL
cmdSchedule.CommandText = "spSchedule".....

i'm currently learning .Net and i can get data out of a database and display in a listview. But how can i access data items in the code behind and format, change, concatenate...do whatever i want to them then display in the list view? Is it even possible?
[Code]....
Maybe an example of what i'm trying to do would be to concatenate a address from the dataset and in a variable sAddress and then attach sAddress to a label in the list view, or add to colums of the dataset together and then show in a label in the listview.

convert the code below to LINQ, converting my project to a wseb version usimg LINQ To SQL. The project contains 10 textboxes to possibly select from, but I'm only providing the first two textboxes to simplify my question.
mySQL_Statement = "SELECT IDENTIFICATION_DATA.NSC,ITEMISCD.RNC,ITEMISCD.NSC1 FROM IDENTIFICATION_DATA LEFT OUTER JOIN ITEMISCD on IDENTIFICATION_DATA.NIIN = ITEMISCD.NIIN"
If Not ((TextBox1.Text = String.Empty) And (TextBox2.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " where "
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "IDENTIFICATION_DATA.NSC IN (" + TextBox1.Text & ")"
End If
If (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "isnull(IDENTIFICATION_DATA.NIIN) = FALSE"
End If
If Not (TextBox2.Text = String.Empty) Then
If astrixState = 0 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
ElseIf (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
MsgBox(mySQL_Statement)
End If
End If
If astrixState = 1 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + " OR IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
Else
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN IN (" + TextBox2.Text & ")"
End If
End If
If astrixState = 2 Then
If Not (TextBox1.Text = String.Empty) Then
mySQL_Statement = mySQL_Statement + "AND IDENTIFICATION_DATA.NIIN NOT IN (" + TextBox2.Text & ")"
Else
mySQL_Statement = mySQL_Statement + " AND IDENTIFICATION_DATA.NIIN NOT IN (" + TextBox2.Text & ")"

There is a page in my project named Messages.aspx that shows the messages received [but obviously], using the ListView control.
I want that the user should be able to see the body of the message on the same page [Messages.aspx] just by clicking the subject of the message, which is ofcourse a link.[Messages.aspx?msg_id=some_id]. Hence the user would actually reload the same page to read the contents of the message.
Now what I want is that I should be able to write some code that would change the <LayoutTemplate> and the <ItemTemplate> of the listview during the runtime. [in the page_load event of course]
Previously the listview would look like this:
[Code]....
After the clicks any message to read it and the page gets loaded, I want the layout of the listview to look like this.

i have the following problem. i'd like to use a listview with paging for mulitple selection of items in a list. The selection is no problem. I do have f.i. a list which holds the key values.
List<Int64> selectedList =
new
List<Int64>();
As soons as the user makes a selection or removes a selection the list will be updated accordingly. Also hold this list info when changing pages of the listview.
[Code]....
This list can be stored either in a session or a viewstate.
My question is how can i retrieve the information of the list back into my listview and thus displaying the selection the user has made when he jumps from page to page.
Below my listview.

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.

So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).

have an annoying problem. i'm trying to update single items in a databound listview. but when i click the update button it gives me the cannot insert NULL value. it doesnt seem to read anything from the textboxes which i have databound from the database. even though text is clearly shown...
i have setup my update statement and parameters, it uses the Update command name and ItemUpdating event. i catch the data from the textboxes by using e.ItemIndex and use the text assigned to the parameters in a SqlCommand.
The thing i'm aiming for too is that when an item is updated it stays on the page where the item was updated, (i was using response.redirect before but it went against my aim since the whole page reloaded)

using asp.net 4 and vs 2010 I have a listview that displays data from a database. I have to configure it to display all column data where present, however, not all columns have data, with the result that blank spaces get rendered where this data would normally be displayed.
The code:
[Code]....
So, for example, some of the individuals that exist in this table might no longer be associated with a specific department, institution or have data in the "Address2" column.

how I can get item values in a ListView in code-behind? I’ve searched high and low during the past 2 days and tried various possibilities to no avail. Data binding is being done in code-behind:
Code:
SQLString = "SELECT Field1, Field2, Field3 FROM Table1"
DataTable1 = LoadDataTable(Connection1, "SELECT Field1, Field2, Field3 FROM Table1")
ListView1.DataSource = DataTable1
ListView1.DataBind()
ASP:
[code]....
The aim is that once a user clicks on a particular row in the ListView a pop-up is displayed which in turn reflects all data related to the record. For the purpose of preparing the data for the pop-up I need to determine the unique record identifier.
I have the same code working perfectly in another app, which has to effect that once a user clicks on a particular row in the ListView a new tab is opened which in turn reflects all data related to the record.

I'm displaying a bunch of items in a ListView. Each item has a button that the user can click if he/she is not interested in the item. What I want to do is this: if the user clicks the button, I want to remove that item from the list but I don't want to necessarily make a datadabase trip for each and every item the user clicks. I'd rather make one DB trip and take care of all the items user has clicked. However, as the user clicks them, I'd like to remove them from the ListView.

Now what I would like to do is to databind these lists in code behind to my ListView. I know how to do this if I only have one list but in my case i have two and in my listView i have fields whose information is in productList list and others in the productDetails list.
Is there a way to achieve this?
Here is some code where I am databinding one List to ListView:

The problem is that Checked property never changes when I click on them. Why does this happen?
Here is the code:

onitemcommand="ListView1_ItemCommand"
onitemdatabound="ListView1_ItemDataBound">

<asp:PlaceHolder ID="itemPlaceholder" runat="server" />.......

I'm currently using a ListView in my webformsapplication. This ListView generates a table with (currently) three columns. "Username", "Organization" and "Locked". These are represented with string, string and checkbox respectively. The checkbox should postback on change...
Should I use <%# Eval("Username") %> or <asp:Literal blablah> to inject the data? This is more relevant for the checkbox... It seems very "dirty" to write <input type="checkbox" id="something" <%# if ((bool)Eval("Locked") == true) /* some unknown code for outputting "checked" */ ;%> />
Or should I use another container alltogether?
