OKi,
in addition to my above answer, there is a solution which uses interface.
First, we implement an Interface:
public interface IRadioButtonListEvent<br />
{<br />
void RadioButtonIndexChangedProc(object sender, System.EventArgs e);<br />
}
As you can see, our interface implements just one method, which will be called whenever selected item index changes.
Now, in the User Control, RadioButtonList1_SelectedIndexChanged should look like this:
private void RadioButtonList1_SelectedIndexChanged(object sender, System.EventArgs e)<br />
{<br />
IRadioButtonListEvent iPage = (IRadioButtonListEvent) Page;<br />
iPage.RadioButtonIndexChangedProc(sender, e);<br />
}<br />
And finally, code for hosting web page. As i mentioned above, page must implement an IRadioButtonListEvent interface.
public class WebForm1 : System.Web.UI.Page, IRadioButtonListEvent<br />
...<br />
<br />
public void RadioButtonIndexChangedProc(object sender, System.EventArgs e)<br />
{<br />
RadioButtonList rbl = (RadioButtonList) sender;<br />
}

Both of your solutions couple the user control and page together very strongly, which limits the flexiblity and reuse.

Handle the onselectindexchanged event in your user control and create an event in your user control that any page can subscribe to that reflects the onselectindexchanged event. A technique called event bubbling.

If you are using 2.0 there is a DetailsView control that can be bound to the master's (possibly a grid view control) data source.

Check out that ASP.NET Data Tutorial series on the asp.net site, they'll show you what you want to do.

i am attempting to write the cookies for a landing page.
i have used the following code to analyse the presence of cookies, but dont know how to write the cookie for the page loading.
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
If Request.Cookies("Landing") Is Nothing Then
'if the name cookie does not exist ask user to enter name
Response.Redirect("landing.aspx")
Else
'if cookies already exist then show landing page
Response.Redirect("tMN_index.aspx")
End If
this seems to work in terms of directing to the landing page.. just need the cookie help....
i basically want the landing page to appear if the cookie isnt present, and then the landing page to generate the cookie if not present.
thank you

As I understand, you want to know how to create a new cookie. Below is a simple example how to do that. Depends on your needs, set appropriate properties of System.Web.HttpCookie object.
Basically you simply add a new cookie object into Response.Cookies collection and that's all. Using Respose.Cookies class you can also remove or change any cookie your application creates.
Dim cookie As System.Web.HttpCookie
Dim cookieName As String
Dim cookieValue As String
cookie = New System.Web.HttpCookie(cookieName, cookieValue)
Response.Cookies.Add(cookie)

Hi all,
i have to validate for a textbox field in ASP.NET 2.0 using C#.
the requirement is that the textfield should accept only numbers.
i want the field such tat it should accept number..... any number of any length.....
please send me the code for the same......
the regular expression validator with the validation expression
ValidationExpression="[0-9]"
accepts only a single digit number.........
how do i make it accept any number!!!!!!!
Thanks,
Ramesh

|

Well, you should change the ValidationExpression to accept more than one character. Also, decide whether you will accept +/- sign before the number, decimal point etc. Than build proper regular expression and that's it.
I strongly recommend to read a little about "creating regular expression" on the MSDN.
And to make it works, and accept any number of digits modify ValidationExpression to "[0-9]*".

include * in your validation expression either at the begining or at the end.

Nice, but when user turn off javascript in browser it will allow him to enter incorrect input. It's necessary to do the same validation on server. ASP.NET validators do both for you.

ValidationExpression="^\d+$"
the above expression is a regular expression validator to validate for numbers......

I don't think you can do it without help.
I am using Office Write from SoftArtisans.
http://officewriter.softartisans.com/
Their product allows you to easily and quickly read excel values on the server and update Cells in an excel spreadsheet. Also they have an activeX control that you can install on the clients. This activeX control has a "post" function (which can be called from a VBA Macro) that will allow you to post your file to an aspx page. I have been able to implement what you wish to do using the Office Writer. I don't know of any other way you can do this without having the user save the file to disk and then using an html file control to post the file to a server.
