The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?

DataTextField="Size" DataValueField="BustId" Width="150px"
AppendDataBoundItems="True">

View 2 RepliesAny limit to the number of nodes you can have in a treeview, I have been having some problems getting it to display with the panel I made. I have actually decided not to use the treeview, in fact may drop this part of the app altogether, but just wondering for future reference. I know if certain browsers have a limit for the the url, but can not seem to find anything, if there is anything, on a node limit. I am using asp.net 3.5 with VB and my browser is IE8, well the only one I tested on.

View 1 RepliesI have notice that the UpdatePanel post every field included on the form on every trigger.
But in most of my cases I use 2-3 UpdatePanels at the same page, and each one is independent.
When I click for update the one panel, then my page receive all the input data of the page (ok this is logical) but I won to read only this UpdatePanels data and act according, and not the other panels data.
So I see that a lot of traffic is happened this way.
So is there a way to say to one UpdatePanel - send only my input data, and not everything found on the page. ?
I have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)?
I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?).
I have a report, which has two sections namely Labour and Spares.In labour section no of records per page must be limited to 5 records and the Spares section have to limit to 10 records per page.If either Labour or Parts exceed the max limit the records must be shown in the next page. Limiting one section by using formulas can be done easily ...but it is very difficult control two sections simultaneously.
View 4 RepliesI am trying to find a solution to control the number of logins on asp.net application. I need to install the application in the client server, and set the number of licences. e.g. only 10 users are allowed to access the app.
Every time someone tries to login I need to check how many user are logged in, compare with the total allowed then authorize that user to proceed.
I tried with Certificate, but I couldn't see where to match the number of logged in users with the max number of allowed user.
Also I would like to use the IP address as identifier, then if I open 3 browser windows, it count only one user logged.
Basically this web application will be sold by licences. We need to control the logins per computer, and not per user, and block logins if the limit of logins are reached.
