ASP ListView: How To Access The Data That Is Databound To The Rows
Jun 4, 2010
I want to access the data that was databound to my list view when handling list view events such as:
protected void List_ItemDataBound(object sender, ListViewItemEventArgs e)
or
protected void List_ItemCommand(object sender, ListViewCommandEventArgs e)
Inside the events, I can not access the data via somthing like Eval("ID")
Currently we are using a very hacky solution:
string id = e.Item.FindControl("lblID").Text;
Where lblID is a hidden control that is populated with data in the aspx file using:
<asp:Label ID="lblID" runat="server" Text='<%# Eval("ID") %>' />
My eyes bleed when I look at this, Is there a better way?

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.

I have 2 pages (let's say one is a.aspx and the other one is b.aspx). In the b.aspx, there is a nested listview control (let's say outer listview and inner listview).Therefore, there is an event on databound for the outer listview. so basically, the event will programmatically bind the datasource for the inner listview.
Now, in a.aspx there is a button to open a new window (with unique window name) b.aspx. The very first time click on the button, a.aspx opens a new window for b.aspx without triggering the databound event. However, the second click and so on will trigger the databound event which is causing an error because there is no data yet in the outer listview.My question is, what could have possibly triggered the databound event while there is no data in the listview?

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)

I have a ListView with many advanced controls and html tags. ListView is bound to collection of profiles when first profile in collection is current profile. current profile has few differences from other profiles ie. flash embed, js and some other stuff. I can access inside of my ListView Container.DataIndex property which gives me 0 as first item in index but i'm unable to use inline If statements like so
<% If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>
this is because i must place pound to access databound item but neither this
<%# If Container.DataIndex = 0 Then %>
do stuff
<% EndIf %>
How can i make inline If ?

I am trying to have a listview which will work like a table with paging. My problem is I need to be able to add more than 1 row at a time. ie I want to click "add new row" multiple times on the same page without the page changing and without the rows I'm adding going away.
Basically I need the user to still see the already inserted rows as well as the rows they are planning to insert on the same page. This would mean the page size is temporarily larger than it should be. The new rows would be added to the end of my data source when the user goes to another page or clicks a separate save button. However the user can add as many new rows while on a page as they wish and the page would simply grow.

I tried to use ListView with following code to display 2 columns for name and address:
<asp:ListView ID="ListView1" runat="server">
<LayoutTemplate>
<ol>
<asp:PlaceHolder ID="itemPlaceholder" runat="server" />
</ol>
</LayoutTemplate>
<ItemTemplate>
<li>
<%# Eval("PersonName") %>
<%# Eval("PersonAddress")%>
</li>
</ItemTemplate>
</asp:ListView>
The problem is the address is not aligned depends on the person's name length.
I want to have 2 columns aligned and with horizontal and vertical grid lines. Can I do that?

I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?
Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.

I have a listview, that shows 8 rows until creating another page to navigate to to see the rest. I can't figure out where the limitation of the number of rows is coming from

To Start with, I am new to .NET. So I am not refer to the right word, but I'll write up whatever I can.
Basically I have 3 input fields and then a search field.
When I hit the Search field, based on the 3 inputs, it needs to get the DataSet and fill it in the ListView.
I believe it is doing it. But when I added the DataPager, it lists only the first 10 rows, even if hit NEXT
Here is the code ib the .aspx page to populate the ListView
asp:ListView
ID="FISIItemsList"
ItemPlaceHolderID="ListFISIItems"
Since the NEXT button is not working, I thought of Adding the DataSet to a Properties. The and getting it back.So I did something like
public
DataSet
dsFISIItems[code]....
Even this doesn't work.
In simple terms, > After the 3 input fields are filled out, when a "Search" Button is hit, it should go and pick the list of items based on that criteria
> The result dataset needs to be binded to the ListView
> Next, the DataPager control should be paging. But it is not paging.
When I hit the next, it lists only the first 10 items repeatedly.

It seems that VS always displays more than 20 rows of ListView in its designer. If a page has quite a few of ListViews, it is a bit hassle to move around. Is there any way to reduce the number of displayed rows?

I previously had a datalist bound to an objectDataSource. Within the ItemDataBound event, i could quite happily access the current bound row as follows:
[Code]....
where ASPNETDB was the database and tblJobs the tableadapter. I could then reference the tblJobs items as job.JobId and job.StartDate etc. Upon chainging the datalist to a listview, I can't seem to find any way of accessing the same data. I've tried ListViewItem and ListViewDataItem, is this the right method or am i missing something?
