I seem to be having problems trying to add an item to a dropdownlist that has a defined datasource:
[Code]....
but, the item never appears in the dropdownlist, regardless of how I try to modify the .add code....
After I execute a data reader and put the readed string from the database in my dropdownlistbox, I cannot add another item in it.Here's my code:
con.Open()
Dim com As New OleDbCommand("Select Status from Table where Id = 'somevalue' ", con)
Dim dr As OleDbDataReader
[code]...
Here is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.
[Code]....
and code bedind

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked

I have a listview which has a complicated Item template that contains a repeater, an objectdatasource and some other controls. On the first run I am only showing 10 Items of the listview. The user has an option to show 10 more ListView Items. If user clicks on show older items; the listview shall add another 10 items. how to go around this since my list view already has a datasource and I don't want to rebind the whole listview all over again. Instead; I just want to add another 10 items.
View 7 RepliesI got 2 listboxes in a window form, one on left and one on right. The 1st listbox have some items while the 2nd listbox is empty. Also there are 2 buttons between the 2 listboxes which used to move item from/to the 1st and 2nd listbox.My problem here is that after I bind the data to the 1st listbox (from a dataTable, using DisplayMember and ValueMember) , and I try to move 1 of the item from this 1st listbox to the 2nd listbox and I want that the selected item is also removed from the 1st listbox by:
lbMembers2.Items. Add(lbMembers1. Text);
lbMembers1.Items. Remove(lbMembers 1.Text);
But the selected item is not removed from the 1st listbox.Also on deselect button when i move item from 2nd listbox to 1st listbox,it displays error message "Items collection cannot be modified when the DataSource property is set."

View 2 RepliesI am viewing items returned from a dataset in an Infragistics chart control. My problem is that due to a weak point in the control, I am left looking for a way to manipulate the height of the chart based on the count/number of items returned by the ObjectDataSource(DataSet).
Does anyone one have an existing C# sample they could let me view of accessing the count of records returned within the code-behind of a page that I could then use within a case statement to set the hight of the control?

I've this checkboxlist with different sports items inside (Example Swimming, Floorball, Basketball and etc). Users are able to check/tick more than one item as they may be interested in lots of different sports. However, I realised that I'm not able to save all the items that the user has checked into the database; only an item will be saved. How can I save all the items that the user has checked into the database?The codes I'm implementing now:cblSportsInterest.SelectedValue (to save the value into the database)

how can I store those selected items in database, and how then I can retrieve them.
"
Is it true to make a separate column for each item, and then if selected, then that cloumn will have "1" and "0" for non selected.

Only that idea occurred to my mind, and I think that I can find better it.

I have a few tables, Listings, ListingImages and a few others related to Listings. ListingImages is related to Listings so that you can have many ListingImages per Listing.
When I query this table I do;

Now this is fine. However, I now want to sort the ListingImages independently within each Listing (by an ImageOrder column I have in that table).
How can I do this and pass all my Includes(...). Would it be bad form to sort the ListingImages within the View as this solution seems to work?

So I have a ListView (assignmentsListView) in an UpdatePanel, being filtered by a DropDownList in the same UpdatePanel. The DropDownList has a list of persons in it and uses autopostback, and the ListView shows the tasks those persons are assigned to.
I am trying to use code similar to this:
[code]....
When I first load the page, the DropDownList shows the first person in the list, and the ListView correctly shows that persons tasks.
If I then select a person who I know has zero tasks, I get an error at the RegisterPostBackControl() method, saying the passed-in control cannot be null.
When debugging, at the RegisterPostBackControl method, it shows that the ListView Items collection has >0 elements in it (the number of elements matches the person selected before the current person).
I am trying to add <li> items to a <ul> programmtically. Is this possible and if so, how?
