Forms Data Controls :: Can Control The First Record Shown In A Listview
Jul 23, 2010
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 need to access a TextBox control inlistview. I have tried the following code behind but I don't retrieve the correct textbox. A snippet of the code is as follows:
I have a listview control on the page.. when the page binds and the listview is presented, there should be only 6 records.. well those 6 are displayed corrected at the top, but then below that is the same 6 records.. and below that is the same 6 records.. this goes on 6 times for the page.
If only 1 record is returned by the query. the page lays out ok and functions as expected.. is there a configuration i need to make to the listview to prevent it from repeating itself the number of records it returns?
I'm trying to create a list of items with a listview (ASP.NET VB) and would like to allow a user to use 1 of 2 checkboxes (or radio buttons), to allow them to mark that record as "approve" or "delete", then once they've made all of their selections, they press a button at the bottom to action each of their requests.
So they might select 10 records to delete and 5 to approve, but I want them to run all at the same time, rather than making them edit a field for them all 1 by 1.
I'm also having a bit of trouble identifying a particular record in my codebehind, is the only way to do it through listview1.items then get the index of it, and compare it to the same sql query somehow?
I have a web form, and an "add vendor" button. Click the button, a modal dialog pops up (ajax:ModalPopupExtender). User selects one of two radio buttons which shows a data bound asp:View in an update panel - this view is data bound to a single row and must be populated by the user. However I also want to provide a cancel button which should close the modal dialog and reset the bound view.
However what is happening is that the ModalExtender closes, but when the "add vendor" button is presented again, it's still bound to the same data. Do I need to clear my data source? How so I reset the forms/views so that when the 'add vendor' button is clicked again the form is presented as it should be (IE the 2 select options, picking one re-binds the asp:View)?
Hi. On my webpage, I have a listview that has a field called BookId. I also have a Detailsview with an ID field. When I add a new record on the listview, I would like to populate the BookID from the Id on my detailsview (there is a one to many relationship between the 2 ids).
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 can pass the data in a dataset from my webservice to my webapplication and databind it to a listview, but I don't know how to seperate the data into the 4 tabs? Is this possible in a way with a listview or using other datacomponents?
If not, should I make 4 select statements in my webservice and send 4 datasets to my webapplication and bind it to 4 listviews each in 1 tab? If so how I can pass a list of datasets from a webservice to a webapplication?

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 would like to ask if there is any control act like grid to display records.The 'datasource' will be a customed class, this dataclass has List<T>, so I will populate each element by iteration into the grid.Any control can I use to work like a grid?The number of records will around 100.This control should also allow the user to select a record.
I have a dropdown box control, populated by an Access data source, and linked to a form control which renders an appropriate record detail when a selection is made. All works as intended. My issue is that each rendering of the page shows the dropdown box carrying the link to the first record, with the detail portion of the page already complete with the information for that record.
I'd much prefer that the dropdown box would carry some text, like "Click to select..." leaving the detail part of the page empty at the first iteration of the page, allowing the user to pick the first record. I can't seem to find any way around this problem with the control or the data, unless I add a record at the top of the file that carries the text.
I have tried almost evrything and nothing seems to work,,, I dont see errors but the code is not firing when I bind in the properties of the button control ,,nor the code behind.
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?
