Which method would be fastest / most efficient?
A) Read all data (822 rows) including those I do not need then filter / output those I do
B) 3 Round trips to the db using params filled via the last query to select only the data I need
I am wanting to build a asp.net page where the user is presented with drop down boxes.
The drop down boxes contain information from an access database.
The access database contains more than 5 tables.
For example, I am going to use a customer website database as an example:
Contained in the database is:
Server Name
Server Type (Shared web or Dedicated)
Customer name
Sites the customer has.
Funtionality:
Say user one wanted to view all records by the server name:
The user would select the relevent server name which is in a drop down box.
This will automatically filter the database results and in turn will display on the webpage all the customer sites associated with that 'server'
Next I want the user to be able to filter those results again, and say the user wanted to filter the sites by "server type", the user would then select the type in another drop down box and then the data will be refreshed to show the sites that are on that sever, and server type.
I'm new for asp.net and web development at all.
I want to filter user input before putting to database.
Are there common technics for this?
I need good css for Gridview just like the mac css
can we provide the filter functionality to gridview like the excel filter.
I have used this gridview in my project nad its working fine.
View 2 Replieshow to implement filters on products as this is the first time i am doing this. This is very common in ecommerce websites which sell computer products (example bestbuy.com) where a client for example would click on Monitors category, upon clicking on monitors client is presented with all the monitors available. He then could filter the monitors using filters for example he clicks on a 19 Inch monitor filter and the monitors update to only display 19 Inch monitors.
how to make this as regards tables in database?
my access database consists of 2 tables. i name it table A and table B.
my idea is, i would like to search the data inside these table A and table B by using a text box and a button.
and 2 radio button are used to control whether data inside table A or data inside table B to be search.
I have a task in which i have to compare 2 access databases
and in these 2 databases, there is a field "Customer_Name" Let's name both databases as DatabaseA and DatabaseB
In DatabaseA there is a list of Customer_Name that includes all the customers
Now I have to match this CustomerList with "Customer_Name" field present in DatabaseB
If Customer Name of DatabaseA is present in Customer Name of DatabaseB then leave it as it is
If Customer Name of DatabaseA is not present in Customer Neme of DatabaseB then rename the name of that customer as "NA" in DatabaseA'S Customer Name field
So i have to perform these 2 above mentioned things, is it possible to do it in asp.net coding ? just with a press of button (in button click even) to save time as the list of customers includes 3000 customers approx
In securing actions/controllers, do I have to create a custom filter or use MVC built-in filter?
To use the built-in attribute Authorize() on an action/controller or create a separate class that inherits the ActionFilterAttribute which has a method (OnActionExecuting) to override and do the authentication there?
In my organization we use nested groups. For a particular usage, we have a group (let's assume that the group name "kuku"), and the names of all the nested groups under it contains "kuku" as well.
We may assume that no other group in the LDAP has "kuku" in the name.
I need to create a filter which will return all the users which belong to one of the "kuku"s group.
Obviously, using this filter will bring only the head kukus
(&(&(objectclass=user)(objectclass=person))(memberOf=CN=kuku,cn=...rest of the group DN...))
How can I use wild card to fetch all users which belong to any kuku?
For example: (&(&(objectclass=user)(objectclass=person))(memberOf=CN=.*kuku.*))
I have decorated my base controller with a couple of action filters. They work fine.
One of those filters sets up the request - does things like set the culture based on the domain, etc.
I also have a handful of actions that require authorization using the Authorize attribute.
My problem is that when an user attempts to request a page they are not authorized to access, the authorization filter kicks in and redirects them to a page telling them that they cannot vie the page.
The issue is that the action filters never run so the culture and other request data is never set. This effectively causes language to be wrong in the view and other data to be missing.
I know that authorization filters run first but my question is this: How can I design this such that I can ensure that certain methods are always run before the view is returned, regardless of the authorization.
i want to create filter in action method for filtering particular user from my database for the login program....
View 2 RepliesI have created one stored procedure which runs on 5000 users in tbluser table with some filter condition in database.There are 4 filtering condition(FC1,FC2,FC3,FC4).Filtering condition has some ListBox and dropdown list of department and countries.I want output as given below:
ID Name StaffNo department Points
1 KK 111 dep1 2
2 NN 222 dep2 1
3 DD 333 dep3 4
I got ID,Name,StaffNo,department in resultset but not points.
points calculation would be based on filtering condition like
if FC1 matched user gained point 1,if both FC1 and FC2 matched user gained 2 point,if both FC1 ,FC2 and FC3 matched user gained 3 point etc.
--in stored procedure i m using dynamic query
DECLARE @SQL VARCHAR(2000)
SET @SQL = 'SELECT U.UserID, U.StaffNo,U.FirstName+'' ''+ U.LastName AS EmployeeName,''?'' AS Points FROM tblUser U '[code]....
all filtering condition are implemented with OR logic.
does a action filter override a controller filter?

I have a gridview populated by a SQLDataSource that is fairly complicated on a dataset changing constantly. It takes a second or so to fetch the data.
I want to have external dropdownlists for filtering the data that appears in the gridview, either with a FilterExpression or with parameters.
The problem is that querying the database to populate the dropdownlists takes a long time, because of the complexity of the query. The values in the dropdowns can vary based on other filters.
Is there some simple way of querying the database only once, for the main gridview, and then somehow querying the local (to ASP.NET) copy of the data to extract distinct values for populating the filtering dropdowns? I am thinking this might speed things up a bit.

a simple way to filter SQL data when it is retrieved by a GridView control?
Among the various applications I need to create are selecting records based on user inputed criteria (via a DropDownList), and excluding records that have null values (which I need to allow in my database) in certain columns.
I have the web page that meet the problem. There exists a gridview and filtering. When Select all by using function A, it is OK. when Filter by using function B, it cannot filter and return no rows. When Select all again, it is OK. I have tested that function B can return the corrected filtered rows. But when databind in the web page, it cannot show and no error?
