How can i get the number of a listview records (or the index of the last record) from within the ItemDataBound event ? I would like to hide one of the controls in the last record, how can i know if the item is the last one ?
View 2 RepliesI experience a strange issue with DropDownList today.
It is bind to SqlDataSource which produce about 1500 item. SqlDataSource working properly and no mistake in SQL.
When i bind it to a DropDownList, first item automatically selected on load. But if i try to select other items, DDL never renders. Width of DDL shrinks to zero. But if i use UP and DOWN arrows, i can go through items which appears on the first line of DDL. Shortly, DDL never render a LIST of data for me as it is supposed to do.
If restrict the data as "SELECT TOP 100 SupplierName blabla..", the DDL works properly. Is there any data limit in DDL? 1500 line is massive for DDL?
With the same SqlDataSource, ListView control is working succesfully.

View 1 RepliesThere 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.

View 7 RepliesI want to create a page on which the website's sponsors are displayed. The information about the sponsors is coming from the database via an ObjectDataSource, and I'm retrieving an Image (company logo), the name of the company, and a url to the company's website. Each Image (logo) is of the same height, but of varying width. I want each Item to be formatted so that the Image is on top, and underneath is a centered hyperlink with the name of the company.
This all seems pretty straightforward ... now for my problem: I want to display as many of these on the page as possible. Essentially, start off horizontally and fit as many as possible on each row. A DataList or Repeater with RepeatDirection=Horizontal doesn't quite do what I want as I don't want to have a fixed number of columns.
Is there an easy way to achieve this, or do I have to manually add up the width of each item on an ItemDataBound event, and then somehow move to the next row when the maximum width is reached? In addition I have to deal with the fact that the width of my Item is the maximum of the Image width and the text underneath.
In my project I have a listview which I am binding from code behind. Now I would like to add a droppdownlist for each item in listview. So my question would be:

Here is a bit of code to show how my listview looks like:

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.
View 7 RepliesI've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

I bind data to listview but the "SI.No" column in listview showing Empty data.
So,how to generate serial number in listview ?
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
View 7 RepliesI have a Listview showing all articles. And i'd like to show the number of comments that... that article has.
Shall i call a method inside the listing ?
Then on my code behind i started implementing the following code:

Where on my listview shall i call this function ? SHould i return an int ?
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.
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)

View 1 RepliesI'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.

It always displays ONLY 10 items although there are 30 items in the datatable. If i use GridView ALL the 30 items are displayed just fine.
