Thanks. But I would like to find when is the reference resolved really at runtime or compile time. We say a simple function call is resolved at compile time and something complex with inheritance is resolved at run time. How can I really see it or make sure that how its done. Is there any way to find it with reflection libraries. If yes give me some examples. Thanks a lot Anand

I would like to know how we can determine whether a function call is resolved at runtime or compile time. Thanks in Advance Anand

It gives an error unable to find property "Name" if i provide "Name" as datatextfield which is correct as the collection directly donot have Name only Collection.Country.Name is available. Even "Country.Name" gives the same error cannot find property. the bound column to datagrid is like as follows when i set datafield as name or country.name it gives error cannot find property anyway Thanks for the reply Not everything that can be counted counts, and not everything that counts can be counted -- modified at 11:45 Wednesday 28th September, 2005

Consider a Collections of Organisations and let that collectionObject be called collectionOrg. Each organisation Object in the collection have name, address and an object called countryObject which has country Id and country Name. I want to bind this collectionOrg to a datagrid. Code for this is OrgDataGrid.DataSource = collectionOrg; OrgDataGrid.DataBind(); and in the html part to bind this property to the But as this CountryObj.Name gives an error. What should I do to handle this error. Thanks in advance With Thanks and Regards Anand Ignorance is Bliss

hi guys, I am building a employee data base management system with lot of datagrid. Its basically a windows app. I am building the whole application in 3 tier architecture. I want to add a combo box to the datagrid. i got some sample from net. They are saying abt adding datagridTextcolumn in datagrid table styles. I tried adding that. No errors but not results i cannot see the combo box. how can i exactly put the combo box in the right cell. How can i map them i tried mapping properties but it does not work and will not work as i am filling dataset using a function in the wrapper class to get a dataset and setting this as the datasource to the grid. so how can i do that any ideas. is my question a bit confusing or vague. sorry for that. how can i do that plz tell me a neat way of doing that. thanks in advance anand anand

I dont know whether my suggestion is right. first check the entries are null or not. If null update with ''. ie blank. does this answer the question. sreejiths answer is a good way but working with insert,delete and update query in data adapter is not that easy.

I feel using resource file is a good way of doing it as web.config is available only for web applications or even a raw xml file can be used. anand

I got a answer from the following link --> What do you people think about this. Is this ok. Does any one like to add some thing to this. Any way thanks to Mr.glsac for this posting in the link below. http://www.ipdg3.com/forums/showthread.php?s=7f10056c91da922279d396089df26820&p=5259#post5259[^] I have answered this question a few times already...and I think I am just going to post the answer here and direct people to it when I respond to them The question I am getting often is: We have two types of controls in ASP.NET, we have HTML controls and Web Controls. Web Controls have some more than HTML, but when do you use one over the other? My Answer (feel free to add onto it). First of all, there are really more than two controls. There are also mobile controls, validation controls, user controls, and custom controls...but yes, I know what you mean by two :-) In any event it comes down to the exact functionality of the page for what type of control you should use. Both can co-exist on a page as well, so you don't have to choose one over the other for a whole page. I base my decisions off the following... HTML Server Controls: 1. If I convert from ASP 3 to .NET and I need to do this quickly, it is faster with HTML controls. Granted only once this was the case 2. If you like the HTML programming model, someone told me he likes it..so go for it! 3. If you want to control teh HTML code output that is generated for the browser...web controls do not allow this Web Server Controls: 1. If you want a VB style programming :-) Just drag and drop controls, and configure in properties almost everything! 2. If you need more functionality on your web page. 3. Web Server controls generate output based on browser type (that is why they are called Smart Controls)...so unless you want to write code to check for browser version and output different HTML...web controls will do this for you. In general, learn both...I find the input control to upload a file very useful, and witha reset button...well some use it, I would rather use a web control button and in code behind set all textboxes to " ". It is up to you, but learn both...in general if you start from scratch on a new site, then start off with the Web Server Controls, and use HTML contro

BEGIN:VCARD VERSION:2.1 N:user;test FN:test user EMAIL;PREF;INTERNET:user@yahoo.co.in END:VCARD This is the content of a file name testuser.vcf this is the business card file for a user. use such a file from asp.net application.

I wrote a aspx page with codebehind in C#. The cs file name is Mycodebehind.aspx.cs aspx file is MyCodebehind.aspx I compiled the output library as csc /t:library /out:anand.dll MyCodebehind.aspx.cs I moved the anand.dll to bin. Every thing works fine. Now come the issue. Now i think the aspx page will be searching for the MyPage.MyCodebehind inside the bin folder as my namespace is MyPage.MyCodebehind. I think so because if the anand.dll is not there is shows unable to load MyPage.MyCodebehind error. So to check that i renamed anand.dll to anand1.dll It gave me an error The located assembly's manifest definition with name 'anand1' does not match the assembly reference.

Is it a proper to design the business logic layer & Data access layer as a web service in a n-tier application. What are the pros and cons of using this. when should i use it and when i should not. My UI may be a windows or web application does webservice affect it by any way. Another Query: What the typical functions required in dblibrary.? How can i optimize database access in a dblibrary? What are the things to be kept in mind when designing a dblibrary? How can i make my dblibrary also database independent i.e. tommorow i should be able to change the database without changing code just change the configuration settings in some resource file)? I am sorry if its unclear . Thanks to all who has answered my previous queries. Thanks in advance for any reply? I would like hear the answer of these queries with reason ie. why something is better or not? with regards anand

I want to build a classic 3-tier application. I want the business logic layer to be fully independent of UI(i.e. it should work well for both windows and web applications well and good). How can i pass the data between the tiers. What are the options available. what about raw xml, dataset, serialized xml or serialized dataset.I would also like to know why I should use one technique over the other. Any help appreciated.

I have a web application running on a server which will authenticate a user against a user name and password. Once authenticated this should pass a url to another server with the username and password as querystring. These two application are different. I tried using server.transfer but it does not work and i came to know it will not work between two different application in two different servers. I also donot want the query string to be visible as it is not secure. can any body help. response.redirect reveals the passwords. i also cannot encrypt the password as the second application does not know that the password is encrypt. i have no control over the second web application. It is a 3 rd party stuff. any help appreciated. Thanks in advance. anand
