Web Forms :: Master Detail Transaction Form Like Windows Form
Oct 17, 2012
I need to develop web application. In my application i have transaction form. Like sales invoice contains 2 tables,header table and detail table. In my web form i should have gridview, in that gridview user should enter data's and save it to the detail table.
I find my own way redundant to perform an insert command in a master-detail transaction. Sample, is a Purchase Order, before inserting the details/items will need to find the master key otherwise were not able to make the details connection. Normally we send command to button object which will submit the whole page rather than part of it and these means were not able to capture beforehand the master key to refer in the details.
So, Im thinking of how you do efficiently a master/detail batch update like we normally do in windows apps.
I have an "Edit" page that uses a FormView bound to an EntityDataSource. The page is called with the ID field of the record to edit in the query string: "EditEmployee.aspx?ID=10". The EDS the FormView is bound to is using: AutoGenerateWhereClause=true and a QueryStringParameter. Below the FormView I have a ListView that contains some child records of the FormView. The ListView is bound to a seperate EDS and also uses the (same) QueryStringParameter.
The problem I am having is when this ListView attempts to Insert or Edt a column I receive an error because I don't have the ID field (EmployeeID) of the parent bound anywhere in the ListView (and obviously, it is setup as a ForeignKey so it fails, like it should). Any advice on the best way to get this ID (EmployeeID) column bound in the ListView? There are many things I can do in code behind, but I would like to solve this in the markup if possible. I can move the ListView so that it is inside of the FormView if necessary.
I am using a "Detail View" to edit the data in my "Customer" table. The fields are "CompanyName", "ContactPerson", "StreetAddress", and "City". If I type data into the first field ("CompanyName") and then press the "tab" key, control moves to the second field "ContactPerson". However, if I type data into the first field ("CompanyName") and then press the "Enter" key, instead of control moving to the second field ("ContactPerson") the program closes the form.
Is there someway that I can control the action of the "Enter" key so that this will not happen?
Also, is there any way that I can have control move from the first field ("CompanyName") to a field other than the seconc field ("ContactPerson") if the content of the "CompanyName" field contains the value "Internal"?
I'm trying to setup is a News module with article listing paging and article detail paging. I have a GridView with paging that lists my articles just fine. In that list, some article titles have links that direct to an article detail page by passing in the articleID to the details page. I was able to setup my details page, which uses a DetailsView control, to use paging by using an ObjectDataSource with pageIndex and pageSize parameters from the querystring. Once on my detail page, I can use my navigation arrows to move through Next and Previous articles just fine.
No matter which article I click in my article list, my detail page always starts with pageIndex 0 and thus not the article I clicked on. I understand why that is because it's going by pageIndex value instead of articleID. What I need it to do is, set the detail to whatever articleID i pass in, then allow me to navigate Next and Previous to THAT particular article instead of starting me off from pageIndex 0.
What control do you use for detail data transaction ?
i am thinking of GridView, however, it lacks of add new row function and lack of bulkediting.
then i found RealWorld BulkEditGridView, it's a good in handling bulkedit, and has new row function, however, it can function well only on load. the problem will appear if i add up a new button, which function to add up InsertRowCount property, a row is created as expected, however, all my previous entry in "new row" are gone.
article on binding to a list and I've got that working fine on one view. But what I'm stuck when doing it off a master record. Everything seems to work except that when I look in the database the detail records previous associated with the current master have their Foriegn key to master set to Null and a new set of detail records have been inserted. I've got a really simple form for this object
The form collection comes back with the expected prefixes:
And the Controller.UpdateModel(master) binds all the properties correctly. But when I call dbContext.SaveChanges it issues the follow sql from sql profiler (psuedo code)
I've got a work around that works but it's pretty hackish and I'm currently not matching up the keys so it's dependent on everything coming back in the right order. Plus I've got to include all the fields that I want updated.
I thought that entity framework's code first was the culprite but I've unit test that and it works fine. I've got a feeling that UpdateModel is somehow removing and re-adding the children. Has anyone else got this to work? Of course, I could throw in the towel and parse the indexed field names myself, but I'm so close!
I've been experimenting with using EF (asp.net 3.5 sp1) with a master detail page. Using northwind as the database, I'm simply trying to have categories as master and products as detail. I have read everything I could find on the net about the where condition and it still fails with this error as soon as I click the select link in the master grid:
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: A property with name 'CategoryID' does not exist in metadata for entity type 'WebAppEF01.Products'.
What strikes me is that the CategoryID column is not exposed by the EF model. That's been rolled up into the navigation element 'Categories' I suppose...but on the surface this seems to create the problem I've running in to. I've tried turning off the autogeneratewhere clause but didn't have success. The code for this page follows below.
I have a ASP.NET website which uses the standard ASP.NET Login Control for authenticating users. The user information is stored in a SQL Server database which is not accessible from client side. I want to write a standalone desktop windows form application which requires user to login with the same credential (username and password) used on the website. For the web-based form authentication, it's simple just to use the login control. Howerver, I have no idea for how to deal with the login for windows form application. My naive idea is to create a login web service which windows form application can utilize.
the possible options to get the dynamic web pages. Existing application: We have windows application to desing the "Screen designer templates". The end user uses this application to make his own screen templates, save the information in xml and get the screen in run time. This works fine for windows based application. Current Problem: Its difficult to provide such screen designer application in web. I mean Drag & drop the controls in web page during the run time. So we are planning to use windows application to design the template. And during the run time user should get his own designed template on web page. We are trying to display the similar web form like as windows form with matching controls. let me know what are the options available to solve this problem.
i am working on a web form. now i am opening a pop up window using window.open. Now i want to send the id to that new window. the link button is in my Data list view so that my code is something like this:
My Windows Form Control is working fine when hosted on Windows Form.It is also working fine on .html host if I use only a TextBox and a Button in that control. But when I add a third control i.e. WebBrowser Windows Form control then .html page is not displaying the control at all.Later I remove the WebBrowser Windows Form control to go to previous state and even then .html page is not displaying the control as it was displaying a TextBox and a Button control before.I delete browser history but no use. I am using the following line in my html page.
I have a function that loops through the control on my page to set attributes. This works fine, except that I only want the attributes to bet set on the controls on the content page, and not on the master page. Is it possible to check where the control resides? Or to only loop through controls on the content page?
I have a web form called default.aspx which has a form with user information. In addition to this, I have an iFrame on the same page that displays a page Secondary-Form.aspx that has a few additional dynamic data fields. I need to do two things.
1. I need to pass the parent form data in real time to the iFrame page to refresh its content and modify it's fields accordingly. Example: If the user submits their Vehicle Choice as Car on parent form, the form item in iFrame will display a radio button that says Honda, and if the user submits their Vehicle Choice as MotorCycle in the parent page, the iFrame will display Harley Davidson as the radio button choice
2. The submit button is on the parent page. I want both pieces of this information (from the parent page, as well as iFrame selection) to be passed to a server side ASPX page to process this information.the default.aspx and Secondary-Form.aspx files are located on different domains.
I am working towards porting a windows application to web. The windows application is quite rich w.r.t. the form controls, complex validations and user interactivity.Basic web forms are inadequate to meet these complexities. So I would like to know the best way to still have the richness on the web pages. I have some ideas and would like comments.
Use DHTML & Java Script to mimic complex controls. There are some macro controls available as part of jQueryUI that can be used and some other third party Java Script controls. I'd like suggestions if there is a recommended control library.Use RIA (preferably Silverlight) wherever rich controls are needed. I'd like to keep this as a last option because it mandates the Silverlight plug-in.What are other popular / preferred strategies?
