Forms Data Controls :: How To Push Down Outer ListView From Nested ListView Control

Mar 13, 2011

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?

Forms Data Controls :: ListView With A FileUpload Control?

Feb 10, 2011

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),

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?

Forms Data Controls :: Delete From A SortedList Using Listview Control?

I'm new to, 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?

Forms Data Controls :: Listview Find Control In Selected Item?

Dec 30, 2010

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?

Forms Data Controls :: Find Control In Listview Edit Mode?

Apr 29, 2010

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.


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.

Forms Data Controls :: List Box Nested In Listview Control Selection

I have a list box in a list view control. I want to access the value of the listbox. I have fixed the height of the list box and the box has scroll bars. If i change the number using the scrollbar and then click on the number (turning it blue) everthing works fine. If I simply change the number using the scrollbar the system throws the error below.

Forms Data Controls :: String.Format Not Working In ListView Control?

Aug 5, 2010

I have a ListView control that pulls a phone number from a db table. I'd like to format the phone number in the presentation layer to look like (###) ###-####.

The code line currently looks like this. The page displays the phone# but unformatted, i.e. 9999999999.


Based on other posts I've looked at in this forum, I've also tried:

<li>Phone: <%# String.Format("{0:(###) ###-####}", Databinder.Eval (Container.DataItem("Phone"))) %> with no success. In fact, this particular line throws an exception in my application (Input string not in the correct format).

The datatype I'm using in SQL is varchar(15)

The MSDN documentation for the String.Format method hasn't been very helpful thus far.
