I tried to filter the data table and order by the records based on ID.
Ny filter string will looks like this.
sFilter= "ORDER BY Column1"
when i tried this, i got the following error."Missing operand after 'ORDER' operator."
I have this GridView with this member details:
Members (ID, Title, Forename, Surname)
I want to use Drop Down List to Filter Members table by MemberType, this means having to Join the following three Tables..
Members (ID, Title, Forename, Surname, Memb_ProdID*) has Foreign Key for MemberProducts Table
MemberType (ID, MembType)
MemberProducts (ID, Duration, Price, Terms, memb_TypeID*) has Foreign Key for memberType table MembType is in Italic and underlined, how do I use this to filter members details in GridView.
I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.

View 1 Repliesi want to create filter in action method for filtering particular user from my database for the login program....
View 2 RepliesI have a form that has dropdown box and user can either select Store Associate or Store Manager, when they click on either, I have GetASsociate function that pulls data from sql database. What i am trying to figure out how to do, is that if they say select Store Manager I want to filter what data to pull from that sql table that has all associates in it, so I was trying use an 'expression' statement to stay if Store Manager was selected, only pull me back the store managers from that table. Then same thing for if they selected STore Assoicate, then only bring me back teh store assocites from that table. But the expression statment does not appear to be working.

I have a table which captures the updated data. I need to generate a report on updated fields.
how to filter the updated data from the table to display in the report.
I'm new to this so i need the sql code or stored procedure to filter and show only the updated data.
Well I have time stamp as well as a column for last changed date.
i need to produce all the fields pertaining to the updated cell in a single cell of the report.
for instance i change the last name of the person - i need to produce the persons firsname , updated lastname, his address and other details in a single cell of a report.
i also need to show the records in both ascending and decending way - like most recent update of the day and first update of the day.

I have two data tables and I need to compare the dataRows and insert all the unequals into a table. See the codes below. Goal: if the checkbox is true I loop through the ItemData table and store that data into x.Data. Next I look for all records that has row("ItemRandomize") = True and finally I add those records to xData table. There is an if statement in my for loop that checks for duplicate records -- This is were the application fails. How to compare both tables and store the unmatched rows.

View 7 RepliesI want to make a filtering table. It will be a table where below each column it will have a textbox. I want to, while the person type a word in the filter textbox, the table refresh, displaying only the items (rows) with that word. I think AJAX is a good idea. Just put the table and the textbox in a UpdatePanel, and then write a code to refresh the table on textbox_changetext event. The problem is that you have to take the cursor out of textbox to have the event fired, and I want the table update while text typing.
View 4 RepliesI am using this code to fill my datalist:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim myConnection As SqlConnection Dim myCommand As SqlDataAdapter
myConnection = New SqlConnection("mydb")
myCommand = New SqlDataAdapter("SELECT * FROM Posts", myConnection)
Dim ds As DataSet = New DataSet() myCommand.Fill(ds)
DataList1.DataSource = ds DataList1.DataBind()

It works and fills the datalist with the whole table. When this page opens the address bar is like [URL].Ii would like the datalist to show all contents in the table with this specific thread ID.

A field in my table can have arbitrary strings. On the UI, there is a drop down having options like
All, Value1, Value2
And the results were filtered by the selected option value. So far this is easy and adding new filters to the UI is not a problem. Needs no changes in my stored procedure. Now I want to have an "Others" option here as well, which will return rows not having the column value as Value1 or Value2.
Apparently this will require a "not in" operator in my query, and will make maintenance difficult, as the list of values is likely to change
making my own filter page for a gridview and have ran into. When the user clicks on the add filter button, I create a row in an ASP table displaying the filter. The filtering works correctly and adds the row to the table. But att the last cell is a button that is created when the row is added to delete the filter. For some reason the delete button will not fire the event ive created for it. Any suggestions? Code that creates the tablerow and button.

I use the Entity framework to map an SQL Server database to objects. The EF is then used to fill a Dynamic Data Site. There are 50+ tables and layout isn't really important. Allowing the users to use it for quick data entry while keeping the amount of code as low as possible is.
Basically, I have four work-hours to find a solution to filter some of the tables on the first letter of one (or more) of the fields. (One filter per field.) When I have one, I have another 4 hours to implement it. Any time I spend more on this will not be compensated.
I have full control over the code, the database structure and whatever else. However, I am limited to .NET 3.5/Visual Studio 2008 and am not allowed to include MVC. I'm also not allowed to add more libraries. Can't upgrade to .NET 4.0 either. So, how can I add such filters in a minimum number of hours?
I want to filter the table in my Listview (mvc2) using values from a dropdownlist shown at the top of the page. The values in the list are hard coded. Next to the dropdownlist I got a "Filter" button that calls the filter method on the controller / How can I pass the selected value from the list to the controller? for now I'm using a classic asp:dropdownlist

I have a table called Student with a lot foreign keys that will be used after to filter students(table rows).The structure of this table is like:
StudentId GenderId DegreeId NatioanlityId
1 2 2 3
....
As a student can speak one or more language,the Sudent Table is linked to language table like this
StudentId LangaugeId
1 1
1 2
1 3
And a student can chose one or many subjects for exam:
StudentId ExamId
1 1
1 2
....
In my asp.net page I would like to filter students via checkbox using ajax for example, student having female and male gender with Degree 1,speaking language 1,2... I filter rows in a stored proc using user defined table,and I have to use a lot of IF statements like this
if(EXISTS(SELECT GenderId FROM @GenderTable))
if(EXISTS(SELECT DegreeId FROM @DegreeTable))
if(....)
else
if(...)
How can I avoid all the IF statements? I have more than 5 filters.It's boring.
