I've an anchor tag in listview itemtemplate, I'm trying to find that control in Listview Item databound event with the below snippet
[Code]....
but lnkEdit is always null.
I wonder why it is not able to find the control while I can see it in page view source.
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 is a piece of my code:

i have a listview. The listview contains a usercontrol with ID="ucEquationBuilder1" which is added only! in the SelectedItemTemplate.I've came along some post which stated you can't find the control in the SelectedItemTemplate unless it is also in the the ItemTemplate.
To me this sounded ridiculous. Untill i ran some tests, and indeed i was able to find all other controls (TextBox's Labels) which where both inside the itemtemplate and the selecteditem template.
To me this is quite frustrating. Is there a way to retrieve the control which is only inside the SelectedItemTemplate without adding it to the itemtemplate?

I have a basic list view, in the edit mode I have a dropdown list, and a checkbox, I want it so that if you choose "yes" from the drop down box the check boxs becomes enabled. I know I need to find the control but I keep getting object refrence error with this code.
[Code]....
the listview renders its layout / item template fine but when I click on edit to send it to edit mode it fails to find the dropdownlist ddlQA1YNM which is a bit ironic cause its the ddlQA1YNM that is making the call to ddlQA1YNM_ondatabound. Now it could be with the fact its on the databound stage. Not sure how that plays into the stack. I call ondatabound to determine what the dropdownlist value is and set the enabled status according on the load into edit mode.
I have a listview where inside Iitemtemplate one button and one label is placed.
I want to access the value of label on the click event of button.
I have a dropdown list within a listview 'EditItemTemplate' and 'InsertItemTemplate" which I am trying to populate from the database with code behind with ItetmDataBound event. Problem is I am getting NullException when I use this code which works fine for ItemTemplate.

<asp:ListItem Selected="True" Text="--Select Item--" Value="0" />
</asp:DropDownList>

I get the "Nothing" as output whever I press edit. How do I access the DropDownList withint he Listview?

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?

Here's my relevent codebehind:

FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;

string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;

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),
