I have a Listview that houses a FileUpload control. However, after using findcontrol the next line of code tries to convert the filename into a string and produces the familar error object reference not found.
Note: I have used identical code in a formview and it works fine.
Here's my relevent codebehind:
protected void AccessDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.FindControl("FileUpload1");
string Fupload = FileUpload1.FileName.ToString();
DateTime DateNow = DateTime.Now;
string DateNowSTR = DateNow.ToString();
string NewImageName = DateNowSTR + Fupload;
FileUpload1.SaveAs(Server.MapPath("~//images//" + NewImageName));
e.Command.Parameters["SponLogo"].Value = NewImageName;
}
I have some controls that are inside a ListView The ListView is inside a View1 The View1 is inside a MultiView1 (You could make a song out of it) How do I find e.g. a Label control inside the ListView. This line of code worked fine until I threw the ListView inside the MultiView

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 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:DropDownList ID="ddlItemtList" runat="server">
<asp:ListItem Selected="True" Text="--Select Item--" Value="0" />
</asp:DropDownList>
[Code]....
I get the "Nothing" as output whever I press edit. How do I access the DropDownList withint he Listview?
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 dropdownlist in EditItemTemplate and InsertItemTemplate which I want it to populate at the runtime while Inserting an item or Editing an item.
I am facing an issue regarding populating a dropdownlist dynamically while in Edit and Insert mode. There are 0 Records in my table and it shows "Empty Data message" in my Listview control. Even the ItemDataBound event does not fire. So I am not able to find the dropdownlist in that listview.

i am using the multiview control inside a page and i am trying to find a control using the javascript function document.getElementById. My Problem is that the function returns null cause it cannot find the control. When i open the code of the page from the browser the active view is not rendered so I think thats the reason why I am getting a null value from the function.
On the HTML code is rendered only the first view or the view that is activated on page load.
Is there any way to find a control inside the view using javascript? or I am doing something wrong?
