Web Forms :: ListView List Controls Display Wrong Data The 3rd Time?

Aug 10, 2010

I have a ListView that populates and displays a user's data (via a profile system in VWD 2008) during Page_Load and also when I go from the EditItemTemplate to the ItemTemplate. Then when I go to the edit screen again, my DropDownList and RadioButtonList controls display the first items in the corresponding tables instead of the correct profile values. I don't understand why the controls populate correctly the first and second times but not on the third time (that's right, the third time is NOT a charm).

Forms Data Controls :: Comparing Data In A System.Web.UI.WebControls.ListView "ListView"

Oct 26, 2010

I have a listview and a dropdownlist that is pulling from an SQLTable that I am using to insert data into the ListView, which is associated with the SQLTable. For the life of me I cannot figure out how to get this thing to not allow duplicate entries into the listview.

If I could get at the data that is inside the ListView I think my problem would be solved. At the moment all the code I have is to simply find if I can at least get the data down to something I can compare, from that step I will have no problem writing something functional, at least functional for my needs. I really could use a hand with this:


I don't personally have access to the SQLTable, but I can have somebody make changes if this should/needs to be done from that end, but I would rather do it from this end in VB. I've been digging through the MSDN Libraries

DataSource Controls :: Uploading Multiple Files To File System And Saving Paths To Database With One Button Click

Jan 20, 2010

I creating a page where our clients can view advertising images and then able to download the images in different file formats. So I need the images and the different download types all saved into the same row in the database so that when I go to display them on the page when they select a picture the right download links will be there. So here where my problem comes in, I don't know how to code it so that I can insert mulitiple file paths into the database at once. The images are saved in a table called images. The downloads are saved in a table called Image Downloads.

Here is the code for the page I have it coded to submit the images to the database but not sure how to add the rest. I have got three different sql datasources for each table not sure if that's the way to go.

Forms Data Controls :: Editable Drop Down List Within ListView?

Jun 15, 2010

I have a ListView that contains a lot of editable items. Every item has some values, like; item name, item price, item size and so forth. I would like to add another editable column which should be a drop down list. This should list which sizes the item is available at, like S, M, L, XL. Some item are only available in S and M, while other items may just have a standard size (meaning none of the above sizes). So for example if you are to add an item called polo shirt and its only available in sizes L and XL then you should be able to do that. And then at the front-end where the users surf the items it should be like that when a users sees this Polo shirt he should be presented with a drop down list where he is only able to select L and XL

I can't figure out how to implement this in the Listview and the database. I have mentioned that I want a drop down list to appear in the back-end, this is not a necessity, anything will do as long as the front-end is showing a drop down list with the choosen sizes.

The operation of reading ListView data into List generic list should begin after clicking the button "GetData".

I saw the following advice:

Forms Data Controls :: Adding A Dropdown List As A Filter Option After Listview Is Displayed

Aug 4, 2010

I have a listview that is displaying records currently based on a dropdown.. works great.. now, within those results returned, i would like to filter down some more.. How can i add a dropdownlist to the page that is populated with data from the listview(only 1 field would be used to create the list ) and if you chose to filter by that drop down, then the listview is revised to display only records with the selected value.


Currently you pick from a drop down.. Report#1, Report#2 or Report#3 Say report#1 returns 100 records.. and the field im going to be filtering on is my "Vendor" field.. so once my listview displays my results, a dropdownlist is populated with all the vendors that were returned with the query.. could just be a few..

Now you are sitting there paging thru all the records.. and realize you really just need to see out of the 100 records, records that belong to Vendor#3, so you pick #3 from the drop downlist and the procedure is called again now filtering on that vendor..
