Add Reference tells the compiler what DLLs to include when building; as well as this - it also tells Visual Studio .NET how to handle things as far as Intellisense is concerned (not that this bit concerns you). Anyway - you can achieve what you need by using /reference:mydll.dll in the cs.exe command line you are going to use.

First of all, thank you for your reply, it was very helpful!
One follow-up question, though: What if I want to make use of the Class (that is defined in the DLL) in a code-behind page? Since I'm not compiling the code in the code-behind page, I wouldn't be using cs.exe and wouldn't have an opportunity to use /reference, correct?
Or am I misunderstanding how/when to use the /reference option?
Thanks again for your help!

Sorry it's taken me so long to get back to you, but the answer is that you wouldn't need to use the /reference here. This is only to add a reference to an external assembly.

Hmm.... I'm not sure you understand. I'm still trying to make use of a class name in the external assembly, but I'm trying to make use of it in a code-behind page, rather than a compiled class.
Specifically, I have installed an external assembly called SimpleChart, which gives me a file called SimpleChart4.dll.
Then, in a code-behind page I say:
Imports SimpleChart4
which is the name of the namespace, and is the line used in all of their example code. However, it gives me an error, telling me that it doesn't recognize the type.
In theory, if I had the Visual Studio.NET application, I could click on "Add Reference", choose the "COM" tab, and add a reference to the DLL, and then suddenly it should be able to recognize the SimpleChart4 namespace/type.
However, since I do not use the Visual Studio.NET application, I'm wondering how to do this without....

Plz tell me
when to use PostBack and when to CallBack.
I understand that,postBack helps avoiding the reloading of some data during page_load or page_initilize events...But, How about CallBack?
With a small code snippet(if possible),Plz explain me.
Thanks a lot.

post back: the whole page is send back to the server(images, html, all)
Call back, only the funcions into the java script is send back to the server and returned.
here is a video about using call back with ajax

Hi all,
I have to make one web page where user can add dropdownlist dynamically. As many time user clicks on one button it add one dropdownlist control to webpage. Is it possible to do this using ASP.NET without java script?
Thanks in advance,

You can use a PlaceHolder control. On every click of the button event, create a dropdownlist and add it to the PlaceHolder
protected void btnCreateDropDown_Click(object sender, EventArgs e)
{
PlaceHolder phDropdownlist = new PlaceHolder();
DropDownList dropdown = new DropDownList();
dropdown.ID = "SomeName";
dropdown.DataSource = dataset1;
dropdown.DataTextField = "Text";
dropdown.DataValueField = "Value";
dropdown.DataBind();
phDropdownlist.Controls.Add(dropdown);
}

Don`t worry.The page is actually loaded from the cache and the user cannot perform any server side operation unless and until you are checking the cookie on page load of every page.

Thanks for the reply.And how I can get the selected row id.
I tried with the following line but it returns the null value.
msgbox(gridview.rows(0).cells(0).text)
I am using VB Language.

|

gridview.SelecteIndex for the index or gridview.SelectedRow for the row itself.
But I strongly recommend that you start reading the documentation in the MSDN about the controls you want to use!
--> google --> search for "gridview site:msdn2.microsoft.com"

An array is not a valid datatype for an item in a database. Or do you mean you want to turn all those values into a single array ? Which bit are you stuck on ?
