I have a ListView showing just a list of concatenated strings obtained from different field of the objects of the datasource. A LinkButton (with CommandName="Edit") in each row Event handlers for OnItemDataBound and OnItemEditing A UserControl in EditTemplate.
Now the problem is, I don't know how to use Bind expression in the UserControl. I mean, how to populate this usercontrol when the linkbutton is clicked? (I tried capturing the control in the OnItemEditing handler. But FindControl returned null, as that handler is called before going to edit mode.)

I am having trouble trying to access a UserControl I created and placed inside the EditTemplate of the ListView. How is it done? I've tried to access it at the ListView's ItemDataBound, ItemEditing and Databound with the following code with no luck:
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.
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 trying to do this as asked earlier. The only difference that I found is additional List item that was included in above code.
I tried to use AppendDataBoundItems=true but it is still not working. I also want to set the its default value to the value that was being displayed in label of itemtemplate i.e. DropDownList's SelectedValue='<%# Eval("DepartmentName") %>' but thie property is not available to me in dropdownlist.
I have a FileUpload control in an UpdatePanel and when user select a file, the full file path will will be stored in a hiddenfield, and during postback, i would like to assign the full file path in the hiddenfield back to the FileUpload control textbox, possible to achieve that?
Here is the code from a datagrid edit command in which I am attempting to populate a DropDownList in the EditTemplate from the database. The result is only one item (the first) from the database, instead of all items.
The reason I have the update panel outside the Tabcontainer is so that when switching between tabs, the screen doesn't flicker with refreshes, etc. But as a result, I can't get the FileUpload working properly. The FileUpload1.Filename is blank, so it errors out.
Is there anyway to get this working properly? I've tried the latest AsyncFileupload within the control toolkit, but this caused all kinds of problems with my pages so that's out of the question. I tried an iFrame too, but this also didnt work properly.
I have a DetailsView where EditTemplate has a dropdown where the datasource is a view from SQLDatasource.
SELECT DIR, NAME, TYPE, CASE WHEN [Dir]=''then [NAME]+' ' + [TYPE] else [DIR] + ' ' + [NAME]+' ' + [TYPE] END AS FULLSTNAME FROM vROADS
In the DetailsView, Data Source configuration Wizard dialog box, I select the SQLDatasource as the data source. Under "Select a data field to display in the DropDownist:" I select NAME. Under "Select a data field for the value of the DropDownist:" I select FULLSTNAME.
When I try to edit I get the error saying "... it is not in the list...".
This is what I am trying to make it happen: The dd list displays the [NAME] data and when the user selects a value from the list, [FULLSTNAME] is actually selected, displayed in the text box section of the dd and is also stored to the database.
Any way of making this happen? I think I get this error because, FULLSTNAME is not a part of the database, but it is in SQLDataSource as a field.
In almost all cases, my edit template and insert template in the formview are the same.
So instead of copying pasting the same markup, i decided to put it in a user control. The display works fine, however, the databinding doesn't work anymore. It works fine if I put the markup directly in to the formview template.
I am using FormView component which has a field that is the sex of the person that I am using RadioButtonList with a simple way to show Male and Female, but want to retrieve the information and OldValue NewValues not anything behind me.
In the FormView Edit Template: <! - SEX -> <tr> <td> <strong> Gender: </ strong> </ td>
I have a GridView that is inside a Web User Control, that is inside an ASPX Page, that is wrapped by the Master Page.
Inside a GridView, I have a template field with DateTime type that has a TextBox inside EditTemplate. I extended this TextBox with CalendarExtender and it works ok in Internet Explorer.
I also have a DetailsView control on the same WebControl that I use to Insert new enrty. InsertTemplate for this field is the same as in GridView (Textbox with Calendar extender).
The problem occures when i click on the Edit link (or try click on the link that displays DetailsView in Insert mode for adding new entry) in any other browser: Chrome, Firefox, Opera.
The problem itself is that the calendar extender does not get poped out. I have a UpdateProgress Control on an ASPX page, that thie control is loaded into, that shows loading image while page is being posted back asynchronously.
In internet explorer the loading image is shown for jst a moment and then dissapears. Calendar extenders works perfectly.
As for the other browsers, the loader does not dissapear and none of ths postback links are working, as if it was waiting for the previous postback event or something else to finish. Finally I have to reload the page to get to the inicial stage or click a direct URL link to get somewhere else.
