Can anyone give me suggestions on how to implement the following requirement?
1. A online wizard (step-by step operation) processes user requests across several ASP.NET pages. The session data is stored in memory until the user submits the request. Once the request is submitted, a XML file is created and the data are passed to XML.
# Case Study: The parent page has a "select" button. Click "select" will pop up a child page. The users can select 1000+ items from a datagrid in the child page. Once the user clicks "confirm", the selected items in the child page will be populated to the selected item gridveiw in the parent page. The user can keep selecting more in the child page and the selected items will be appended to the gridview in the parent page.
- What's the best way to extract strings from a text file and convert to a dataset in memory and then present it in a datagrid in UI?
- What's the best way to persist and manipulate a large dataset across pages? Session? or ViewState? Can it be accomplished by LINQ?
The app doesn't interact with a DB. Once the request is submitted, it will convert the in memory data to a XML file. What technology can be used to accomplished this?&nb
I have searched on net and even i worked on 2 huge shipping projects.
Everywhere i found that while binding data to control use dataset but when we save, they recommend use command (use generic collection and create command object with store procedure) why not we use dataset as in .NET 2.0 it is improved lot and data adapter has new feature batchupdatesize.
why we need to create property page which maps to all column in a database.
E.g. if i have employee table with empid and empname in database then i use to create emp.cs with properties of empid and empname and use same properties for saving. If i use these properties for validation in business rule then no problem. But why we use them in saving for creating command object.
I follow the tutorial and create DAL with Dataset. I created a Table Adapter with many column, but when i Call a simple Get for 2 column only. The system display 2 column and the rest column with empty data.
My question is that will this affect the performance? because i only need 2 column.
example: Table with 40 column define in Dataset in DAL. I have GetMember from Dataset with 40 column, some request only 1 column (with 39 empty), some request 22 column (with 18 empty column). Will this affact the performance?
Should i create a seperate DatasetAllColumn, Dataset1Column, Dataset22Column ?? so system only return exact column i need. and hofully the performance is optimized to it best.
i have a stored procedure which returns three tables to a dataset ..... now i need to merge all three tables to a single table from d same dataset
like dataset1 has table1 table2 and table3 .... i want all the three tabels to be merged into dataset1 itself .... instead of three diffrent tables so that i can show all three table data in a single datagrid as a compact data and combination of 3 tables from d single dataset.....
can some1 help me please.....
I'm looking to make a user control to display the 3 most recent posts from a blog on my home page. I've googled around a bit and found a few ways to do this, but none I'm quite satisfied with.
I looked at the XMLDataSource control, but I'm concerned about exception handling. If the remote feed fails, I want to just hide the usercontrol and let the rest of the page display as normal. There seems to be no clean, declarative way to handle this. An OnError event would be nice, especially if it had an e.ExceptionHandled property on the EventArgs object like some of the other DataSource classes.
Scott Guthrie blogged about an RSS Toolkit for .net 2, but that was four years ago and hasn't been updated.
I'm leaning towards Linq to XML, which would probably work fine, but I can't help thinking that there must be a simpler approach to reed RSS feeds since it's such a common problem.
I have a silverlight application and WCF service all made in VS 2010 , i had hosted my site to web server which contain Window 2008 and IIS 7.0
now the problem is i have another application which is a window application developed in VS2008 , when i try to add the service reference it gives me error
The document at the url
http://220.127.116.11/HRDev3/Service.svc was not recognized as a known document
The error message from each known type may help you fix the
- Report from 'DISCO Document' is 'There was an error
- The request failed with HTTP status 400: Bad Request.
- Report from 'WSDL Document' is 'The document format is not
recognized (the content type is 'text/html; charset=UTF-8').'.
- Report from 'http://18.104.22.168/HRDev3/Service.svc' is
'The document format is not recognized (the content type is 'text/html;
- Report from 'XML Schema' is 'The document format is not
recognized (the content type is 'text/html; charset=UTF-8').'.
Metadata contains a reference that cannot be resolved:
Content Type application/soap+xml; charset
