WCF / ASMX :: WCF - Nested Datacontracts And CollectionDataContract?
Dec 23, 2010
I am a bit stumped on setting up a WCF service where you have nested datacontracts and lists/arrays. a hint on the best way to declare the datacontract for the XML below.
I am Adding Webservice Reference in my project . WSDL , Disco , XSD files are created in my project.now , my issue is how to check weather WSDL showing correct DataContracts or not. I dont want unwanted datacontracts to be downloaded .
I need to know the best way to do the following. I have nested business level APIs (say level 1 & level 2). L1 needs to call L2. Both APIs use the database layer directly at their own nesting levels.
Now, in the database layer, I fetch the db connection from the pool each time as follows:
SqlConnection conn = new SqlConnection(connString); conn.Open();
Is it proper to fetch the db connection each time on every DB level call as above? I know it will return a connection from the ASP.NET connection pool. However, wouldn't it be better to maintain the same DB connection throughout the nested calls (or throughout the current http request lifetime)? Will fetching a connection from the pool each time cause issues with nested TransactionScopes?
Is there a better, cleaner way to do this in ASP.NET 2.0?
An ASP.NET 2.0 page displays a datalist of records. Each record can have many dates, so the dates are in a nested gridview (I chose a gridview over a datalist here because we want to be able to delete a date and this is easier done in a gridview). The parent record can never be deleted.
The display works fine: the nested gridview gets its datasource during the parent datalist's OnItemDataBound event.
The problem: the nested gridview's delete function. The date gets deleted without a problem (handled in the OnRowDeleting event), but somehow the redisplay is untying all the other nested gridviews from their datasources. The delete does not appear to cause a page postback, so I don't know how the other nested gridviews are losing their datasources.
I'm trying to create a nested gridview, but I'm stuck at the editing/deleting part of the nested gridview. (Below is my code).The nested gridviews are filling out nice, I've set the DeleteParameter in the SQLDataSource, but I'm still getting this error when trying to delete a criteria: 'The Gridview 'gvCriteria' fired event RowDeleting which wasn't handled.'I've tried to create a method 'gvCriteria_RowDeleting', but that didn't seem to work out.Someone who can give me a piece of advice? Would it be possible to fill the gridview without using gvDomain_rowDataBound? Dries
Have the MultiView1 display only if Frieght values exceed 15.50. If check box is checked, retreive the row values of the Gridview1 and Gridview2 to perform a task.There will be two check boxes. One will be conditionally hidden. Each check box has a different function.
Example: Send an email notifying this entry has been flagged. I am using Visual Studio 2005 with ASP.NET 2 due to availability of resource. I have checked out numerous sites without finding the specific answer.
For example: [URL]
The following a simplified representative example of what I am trying to accoumplish. It uses the Northwind.mdb access database with just the Customers and Orders table.
In Nested Grid, we get a '+' sign. The problem is that '+' sign appears all times, even if there are no child records for that row. 1. Can we enable/disable OR Hide/Unhide '+' sign. depending on if child rows exits.2. OR alteast we can put some bgcolor indicating to user that this record do have child rows. Without any indicator user may feel quite annoying to click on '+' sign and nothing happens.
I have designed a collapsible nested gridview project using this article as a reference Collapsible Nested GridView with Paging using ASP.Net. I am trying to modify the code to collapse a gridview when another gridview is expanded so that only one nested gridview will be open at a time.
if i have the web application with many pages like add order page, edit order page, and delete order page actually they also interact with the Sql Server 2008 and i also create web service page call Sales_Service.asmx. i know just i need to put something like query into Web Method in Sales_Service.asmx but i have a lot of queries, i don't know which query i should put into it and how the web page call the Sales_Services.asmx
A customer reported that our asmx web service is continually increasing in memory (mem usage as well as private bytes). We are able to reproduce the problem in our lab with Windows 2003 Server SP2 (fully patched) on some of the machines. The customer is using Windows 2008.
We created a Hello World web service targeting the 2.0 framework built under VS2005 SP1 and a test client that continues to call it. The memory increases steadily - approximately 40K per client request. If the test app is paused, the memory remains the same. When it is closed, the memory drops. Explicit calling of GC.Collect does not drop the memory.
We have run the memory profiler on the service and the leak is all native memory. We have uninstalled/re-installed the Framework on one of the machines but no difference. To our knowledge all of the security and IIS settings are not modified. We have compared app pool, default web site and virtual directory properties to machines that have no problem and they are identical.
I have a .net app developed in .net 4.0 version. And I implemented an asmx web service in this. Now I want to call one of the webservice method in another classis ASP application java script function.
I have datatable consist of 20 records and i want to bulk insert into sqlserver through the asmx webservice. Can anybody guide to me or provide Sample BusinessLogic and webservice code.
Can I use the concept of the MS Chart Control in a web service page? Basically I want to send some data to my web service then create a graph, save the image and send the image URL back to the calling device so it can be displayed. How can I accomplish this?
Does anyone know if its possible to have a nested repeater, with the nested repeater initially collapsed and expandable via the ajax CollapsiblePanelExtender
I doing a nested for loop to achieve from #123,33.5,1283485089#44.6,Timestamp#124,66.7,timestamp#55.7,timestamp#125,76.4,timestamp#42.8,timest amp whole string to #123,33.5,1283485089#123,44.6,Timestamp#124,66.7,timestamp#124,55.7,timestamp#125,76.4,timestamp#125 ,42.8,timestamp. My code get me back same thing again
Dim i = 0 Dim rsplitdata As String() Dim row, item As String Dim inex Dim rdata As String() = TextBox1.Text.Split("#") For Each row In rdata rsplitdata = row.Split(",") If (i = 0) Then inex = rsplitdata(0) 'rdata(i) = inex + "," + rdata(i) Else rdata(i) = inex + "," + rdata(i) End If i = i + 1 Next For Each row In rdata rsplitdata = row.Split(",") For Each item In rsplitdata TextBox2.Text = TextBox2.Text + item.ToString + vbCrLf Next Next
I cant get my nested loop to output the right code:
If pagesreader.Read() Then ' if subtitle exists then output mydata = "<h2>" & pagesreader.Item("documentcategoryname") & "</h2>" While pagesreader.Read() mydata &= "<h2>" & pagesreader.Item("documentcategoryname") & "</h2>" If (pagesreader.Item("documentcat") = pagesreader.Item("documentcategoryid")) Then mydata &= "<p>" & pagesreader.Item("documentname") & "</p>" End If End While End If produces: About Us About Us doccy4 Map Of Medicine doccy5
When I need it to procude: About Us doccy3 doccy4 Map Of Medicine doccy
So I have two nested view models, CreditCard -> BillAddress. I have a view, "EditBilling", that has EditorFor(CreditCard). The CreditCard EditorTemplate has EditorFor(BillAddress), and the BillAddress EditorTemplate has EditorFor(BillState).
The end result is a select list with id "CreditCard_BillAddress_BillState".
I need to reference this in javascript, thus need to know the ID. In other situations, with non-nested ViewModels, I have used the following code:
The problem here is that the ModelMetadata.PropertyName property is only aware of the current property, not the parent(s). So I end up with the following:
$('#BillAddress_BillState')
How does one go about getting the client ID of nested strongly typed helpers?
I'm still new to ASP.NET, and I'm trying to rewrite a simple booking/reservation system I did in ASP, but I'm struggling to find an equivalent technique in ASP.NET.
Basically, it a nested recordset. The first recordset returns weeks from a calendar. for each record returned, a basic table row is created, showing the dates & prices then the start of the week is used to query a bookings table to see if there are any bookings for that week. If there are bookings, the <tr> & <td> tags are modified to change to colour & wording to reflect the bookings.
I have two tables that effectively have a many to many relationship between them. Effectively I want to perform a query that returns results just from Table2. For simplisity table2 has 4 fields: theId, ForeignId, Info, extra
In table2 there can be multiple records with the same value of ForeignId (but each will have a unique theId which is the tables primary key).
I want to perform a:
select top (1) * where ForeignId=x order by extra
which will select 1 record for a given ForeignId
However, I then want to wrap that within an outer query where I have a list of foreignId (ie where ForeignId in ListOfX) but I want to return 1 result record for each value of foreignId. Does that make sense? So the result will be a set of records with one record for each value of foreignId and that record would have 'info' from the top(1) record from the inner query.
Using MVC 2 for what it matter. (And also keep in mind for some reason I NEVER used Nested Master Pages)
I got a single Master page that work across my site.
However, I found from the design now, that each "Area" have a different subnavigation.
Figured it might finally be a reason to use Nested Master Pages....resulting into a lot of swearing over here...
What I did:Add a "Nested Master Page" to the "Shared" folder of a specific Area (project/Areas/xxxx/Views/Shared/NestedMasterPage.Master)VS bring up a box asking to specify a Master Page, and I select the only one i have (project/Views/Shared/Site.Master)Leave it as is, I add a new View and for it's Master Page I browse to the new Nested Master Page.When I click Add, the following Error comes up:"The ContentPlaceHolder 'MainContent' doesn't exists in the Master page '~/Areas/xxx/Views/Shared/NestedMasterPage.master'. Please choose a valid ID for this Master Page.Bit buffled..the code for the nested master look like this:[Code]....
'MainContent' right there, or what is VS talking about?
I have an ASP.Net page which has several UpdatePanels. Each UpdatePanel loads an UserControl, and per UserControl, sub UserControl(s) may exists. In order to achieve partial-refresh, each sub UserControl will be carried through UpdatePanel. Those UserControls have input controls, and corresponding validator server controls.
The problem is, validators in a sub-UserControl will also trigger the validation in its parent UserControl; however, I'd like separate validation into scopes based on UpdatePanel.
I'm using Visual Studio 2008 and .Net 3.5.
-- EDITED --- E.g. I've an UserControl called "AddableDropDown" which is a drop down list that provides the ability of adding new list item on the fly. It consists of a drop down list for illustrating the currently available items; a asp:textbox for entering the title for the new item, a asp:button for submitting the new item, and a "RequiredFieldValidator" target on the asp:textbox.
The "AddableDropDown" will be used in different UserControl-based "web form" which has other kinds of inputs and Validators.
The goal I'm trying to reach is separating the Validation of the AddableDropDown from each of its instances, as well as each parent control of it.
