I have a need to add a new report to my page, the differnent parts of the page are all using a objectdatasource to populate the data. The new report because of all the data being returned i have started to use a repeater and a table in the ItemTemplate. Just binding the objectdatasource to the repeater works fine, but returns all the records and causes the page to be very long. I found this link for adding paging to repeater, but its setup different than what i have

Is there any way to use what i have already and add paging to the repeater?

View 2 RepliesI have a table with 500 rows and when I try to display them all, the response is really slow (local server). The situation gets even worse when I try to sort the results by a specific field. The filtering process is done in a store procedure by passing the parameters.
Well, here is my code:
[Code]....
I have 2 textboxes (start/end dates) and 2 listboxes which I use to filter my data. Here is my goal:
-make the response faster;
-including paging (does paging bring all the data or it fetches the data as I click on a specific page?)
my solution currently has a website project and a class library project. I am attempting to access a session object from my class library but it is always returning null. In a settings class in my class library I store these values like so:
private static SessionProperty<WebUser> _currentUser = new SessionProperty<WebUser>("CurrentUser", delegate { return new WebUser(); });
public static WebUser CurrentUser
{
get { return _currentUser.Value; }
set { _currentUser.Value = value; }
}
I can access this just fine from any aspx page codebehind like so:
Settings.CurrentUser.User.ProviderUserKey.ToString();
However, if I attempt to do the same thing from a class in my classlibrary project it always returns null.
I have a form in a page and a panel inside the form.The panel gets loaded with dynamic controls like radio button and text boxes.
User is allowed to choose any radio option and enter any value in the textbox beside it and then goes for submit button to move to next stage.
Problem Descritopn:
I load the controls in the panel based on the index of a combo control on the same form.it is done in selectedIndexChanged - This is working fine.
When i go for the submit button and ask for the textbox control, it says "object reference not set to instance of object", denoting that instance is not available. Moreover the panel control list gets empty automatically.
I'm an experienced PHP programmer that is new to ASP.net (C#). I'm trying to figure out how to do a manual echo of a specific field from an SQL database and was wondering how you do an if condition in case the field would meet certain criteria ?
What I want the script to do is check in the database if a certain condition is activated, then the html page should echo a windows media player object with the source of the video coming from the database itself ( $line[Video], and if the condition isn't active then either don't echo the player or just echo an old video (in the script I'm just printing a message).
