Forms Data Controls :: Paging A Repeater That Is Connected To Object Datasource?
Oct 6, 2010
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
[URL]
Is there any way to use what i have already and add paging to the repeater?
can you please help me to brainstorm the possible causes of this error. I've got a paged repeater with localisation bound programitcally to an sqldatasource using a stored proc. I can post code if needs be but it's rather long. I'm looking for typical causes of this error + will make note for future reference!

I have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.
My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:
"Object reference not set to an instance of an object"
I'm just starting out in ASP coding and would like to know what I'm not doing right?
I am trying to experiment with things as a beginner and want to use paging in Repeater Control. Since Repeater control is light weight, I want to use that. I have heard of two methods: PagedDataSource class and the other that I dont remember. I wanted to attempt both of them. How do I proceed?
how can i maintain the selected checkbox value in the repeater when i do a paging to a next page? While i go back to the previous page, the checkbox value that i have selected is still remain?
I have a strange problem. I have made a PagedRepeater control, which inherits from the Repeater, from a tutorial I saw here: http://www.4guysfromrolla.com/articles/020905-1.aspx. It's in VB and I'm in C#, and it didn't quite have all the features I was lookingfor, so, I've modified it quite a bit. I added support for a SqlDataSource control, as well. The only problem is, that it always returns the first item from the SqlDataSource, even when the CurrentPageIndex on the PagedDataSource is set to a different value.
I am using a custom membership provider. I needed to bind a repeater to a membershipusercollection but the only way I could think of was this:
There is no method to return a lcollection of membership users by userid. I basically have a friends table with a userid and a frienduserid field. both are foreign keys to the user table. So say I am userid 1 and I have two friends userid 2 and userid 3.
I needed to get a collection of membership users who are my friends (user 2 and 3)
So I did this:
Code: Dim lstAccountIDs As List(Of Integer) = bl.GetFriendsAccountByUserID(iUser) Dim mUsers As New MembershipUserCollection For Each a In lstAccountIDs mUsers.Add(Membership.GetUser(a)) Next
I get their id's and add them to to list(of Integer) then I loop through the list and get the particular user by id and add them to a membershipusercollection object.
I now need to add paging to my repeater control that uses that collection as a datasource. However the membership provider doesn't give me the ability to specify a pageindex or pagesize etc. It gives me those options in the GetAllUsers function but I need it to work in the above scenario.
using System; // We need these namespaces imported to work easier with database using System.Data; using System.Data.SqlClient; // Here is PagedDataSource class located using System.Web.UI.WebControls;

Record loaded into control but when i press next button then next 10 record showing properly but when i want to see another next record then it shows same record.
e.g. i have 40 records in my db then first time it shows 1 to 10 record
when i press next button then it shows 11 - 20 records
again i press next button then it shows 11-20 records instead of 21-30 records...
I want to export all repeater data in excel file i used following code but it take only first page data means page size 10 it export only 10 record i want to export whole repeater data
