Forms Data Controls :: Loop Through All Pages Of ListView Control?
Jan 3, 2011
I have a ListView control with multiple pages of records. Is there a way to loop through all of the records in all of the pages ? Unfortunately the code below(where BillLiistView is my ListView control) only lets me perform action on the rows that are currently displayed.
foreach (ListViewItem item in BillListView.Items)
//perform some action
There have been a few datapaging questions tonight, but mine is a bit different..
I have a regular datapager, in a seperate project it seemed to work fine with the same query and templates, but when I use it in my page, whenever the I try to page I get the emptydatatemplate when there should be data..
Here is my current ListView
I have tried binding data OnPreRender and setting the page properties under the OnPagePropertyChanging events.. still only getting my empty template whenever i navigate through the pages when there should be plenty of data..
I have anested ListView control. I also implemented a jQuery to automatically expand the TextBox control inside of the nested ListView Insert Template. The problem is, when the Textbox expand, the outer ListView control is not; therefore, the Textbox control expands underneath the buttons of the outer listView control. How do I expand the outer ListView control as the nested ListView textbox is automatically expand? One great example is in Facebook where if I add a response comment, it'll automatically push any comments below mine down. If nested Listview control is not the best way to do this, what are my options?
I made my own master-detail pages using a listview. Rather than url, I use a listview event to set a session variable and response.redirect to the detail page, which on Page Load, loads the data from the database using the session variable, where it can then be edited. The details page is basically just text boxes and dropdownlists, but I used some third party controls and it all looks really sharp.
Here is the corner I pained myself into. Several dependent dropdowns on the master page filter the main listview. If I go back to the master page using response.redirect, the user would have to use the dropdowns again just to get back to where they were before they went to the details page. This is just not going to work.
To further complicate things, I wanted the master page to have paging on it. So if a back button reloads the page, they would have to set the dropdowns again, and page through the data again if needed. Egads.
I'm making a fairly simple online database where a user can upload a PDF file, along with 4 other data fields to a SQL DB. I have it working ok, sending the PDF to the DB as binary data. The problem is I would like to use a ListView control for the user to enter all of their data and choose the file to upload. When I use a ListView I receive the following error:
No mapping exists from object type System.Web.HttpInputStream to a known managed provider native type. I've included the code I'm using to send the file to the DB (protected void ListView1_ItemInserting),
I am using a listview control and wanting an image to display if my DB is null for that record. I have used NullImageUrl="~/images/default/image-not-available.jpg" for my gridview controls and this does work, but does not work for ListView controls.Is there something similar i can try?
I have a page where I use the ListView and DataPager.My listview is populated as a table where each row has a bit data a dropdownlist with some values and a link button. Now I am trying to pick out the selected value from dropdown list when I kick on my linkbutton. As long as I'm on page one, everything is woriking fine. But if I go to page three then I can not pick out the value I selected in the dropdownlist. I have tried to add a textbox in the listview and then I am able to get the value out I typed into the textbox independent which side I'm on.
Why can I pick out the value from textbox but not the selected value in dropownlist?
Here I've a listview control whose datasourceid is set to one sqldatasource, listview contains a panel in a itemtemplate region. In the panel there are some lables which are bounded to the column present in sqldatasource. But In one label I have to assign some other value dynamically. can any body tell me how to access that label and assign value to it. Here's the code
I have a ListView control that only displays one record at a time. I have a LinqDataSource that can return one or more records. I have a function that determines the number of records and returns a psuedo random number between 1 and the number of records returned. When the page first loads, I want to display a random record. After that, I want the datapager to move the user normally through the records.
In my Page Load Event, if Page.IsPostBack is false, I get the random number. Let's say for simplicity I have 15 records and the randon number generated is 6. How do I tell the LinqDataSource to display the record at index 6?
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?
I have a listbox control that is used to insert and update data. There is a checkbox that some users should be able to set while others should not. In what event shold I set it's enabled property and what would the findcontrol string look like?
