You do it the same way you did it in ASP. Remember alert has nothing to do with ASP, it is a JavaScript method.

This question caught my eye....
How can you display a messagebox on the clientside in ASP.NET using C#?
I have web page (mypage.aspx and mypage.aspx.cs) with a data grid, when the user tiggers the update command a message is sent to the update function. How can a make a messagebox pop up?

ASP.NET is a serverside technology. You can't use it to popup a message box on the client side. You can only control how the form is rendered tothe browser using C# or VB.

You can't and I never said you could. I was just telling Anonymous that the way you display a messagebox when in the ASP.NET environment is the same way as you did it in and ASP environment. i.e. You return a JavaScript script block back to the client with an alert call in it.
I was thinking that Anonymous thought that ASP.NET would have some fancy new way of doing it, which it doesn't

Give this statement after the ASP code that does the update.
Response.write(" ALERT('UPDATED');")
Hope it helps

Hi,
I'm converting a http form to .aspx and I've managed to change all the fields to controls that will run at the server. However I keep running into a problem, I can't seem to get the user input from the text control.
For example
is my text control
and the user enters some text in it.
I then try and get the text by using
string a= Text1.value
and despite the fact that the user entered the data, a is equal to ""
Thanks for the help!!

|

Use
string a = Text1.text
Best regards
Anders

I tried using the text property but that property doesn't exist for a HttpServerControl.

this should be simple...i'm trying to set the text part of a file input with some javascript. only it won't do it. the alert below always comes up blank. what am i missing??
here's the html i have:
<input type="file" name="fileImage" value="something1">
and here's the javascript i have:
function image(theForm)
{
var test;
test = "something2";
theForm.fileImage.value = test;
alert(test);
}
thanks!

I hope someone has the answer to this
I have a site in regular old asp 3.0 on IIS 5 -windows 2000.
The site is basically a fancy FTP GUI so users can view files/folders and then download them. What I am trying to do is use the filesystemobject (vbscript) to get a list of the folders/files on a remote data share. I setup the IIS anonymous account to use a domain account instead of IUSER_ComputerName because this domain account has read/write/change permissions on both the IIS box and the data share. Now my problem is that when I run the code below, I am getting an error (not sure what the exact error is)
<br />
'//the UNC path is being pased with URL encoding<br />
ReportPath = Request.QueryString("UNC")<br />
<br />
Set fso = CreateObject("Scripting.FileSystemObject")<br />
'
If fso.FolderExists(ReportPath) Then<br />
Set aFolder = fso.GetFolder(ReportPath)<br />
<br />
For Each aFolder In aFolder.subfolders<br />
.....<br />
Next<br />
Else<br />
errMsg = "Folder/File does not exist or access is denied"<br />
End If<br />
why am I getting this? is it because I am not using a literal for the folder path or because I am not getting authenticated to the remote server?
When I tried this on my local box using VB, it worked fine as long as I didn't use a variable to refer to the UNC path. It may also have worked becuase I have a drive mapped to the UNC path.
I did find one or two articles on MSDN, but it is still unclear to me. This article seemed to have the most information...
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnauth/html/dnauth_security.asp
any ideas? I'm so freakin' confused.

it would be helpful to let me know how to return the error instead of yelling at me. 
but thanks anyway.

Sorry, don't get me wrong: I was not yelling at you, I was instructing you on:
1. Put a "On Error Resume Next" just before the line where the error occur.
2. Put a Response.Write("Error: " & Err) just after the line where the error occur.
3. Give me the error number so I can help you further...

no worries.
using err.number - nothing is returned (i get a big fat zero).
here's the revised code
<br />
Set fso = CreateObject("Scripting.FileSystemObject")<br />
on error resume next<br />
If fso.FolderExists(DataShare) Then<br />
Set aFolder = fso.GetFolder(DataShare)<br />
For Each aFolder In aFolder.subfolders<br />
....<br />
Next<br />
Else<br />
sysErr = "Error Number " & err.number & " Error Description: " & err.Description <br />
errMsg = "Folder/File does not exist or access is denied"<br />
End If<br />
<br />
and just in case it matters the variable "DataShare" is equal to "\\servername\sharename\crp\Daily Reports\"

I know that you should be able to do this...
I place my Connection control on the form and set it's properties..
I add a Command control on the form and set the SQL statement I want
I add my DropDowList control, set the dataSource property, set the properties to bind the text in the list and the values behind the text for my selection...
but when I run the form I get a blank dropDownList.
I can do the binding in code but I really don't think that I should have to.. This should work.
Any takers on this one. I am stumped.

I don't have much experience with using vstudio for webforms, so I don't know how much code it is generating, however, unlike windows forms, webforms cotnrols require an explicit DataBind() call.
If vstudio isn't generating that call, then you will need to write it.

As Andy said for WebForms you need to specificaly call the bind method when you want it, generally on Page_Load.
So in the Page_Load event put DataBind() bit.

Ok, I placed a Page.DataBind() in my Page_Load event and now I am getting the following error:
An invalid data source is being used for DropDownList1. A valid data source must implement either IListSource or IEnumerable.
Line 11:
Line 12:
Line 13: <asp:dropdownlist id="DropDownList1" style="Z-INDEX: 101; LEFT: 88px; POSITION: absolute; TOP: 88px" runat="server" width="184px" height="24px" datasource="<%# DataBinder.Eval(OleDbDataAdapter1, "SelectCommand") %>" autopostback="True" datamember="Products" datatextfield="ProductName" datavaluefield="ProductID">
Line 14:
Line 15:
When I attempt to bind the DropDownList, what do I set the data bindings to? I get a dlalog box that has alot of options in it, and I select the OleDbDataAdapter1.

You will need to set the datasource to a arraylist or dataset or datatable, etc

Hi all !
I get this error when doing a POST to an processing page (no UI). How can I get rid of this? I dont want to use ViewState (and just want to catch the exception). Page.EnableViewState = false does not fix this. It seems the page wants it all the time!
More info:

Exception Details: System.Web.HttpException: The View State is invalid for this page and might be corrupted.

Sorry, can't help  , was wondering however, can we have a sneak preview at the site you are doing all this stuff on? Would love to see it.

Sure, when it is working a bit more like it should! At the moment it works OK, but I'm having problems with getting my "data" displayed correctly (need to take 2d data, then transform to 3d data, do a sort and then back to 2d data, so everything is displayed like it should, oo how I hate recursion!)
But I will let you all know as soon as its "viewable" and "semi-functional"! Hopefully by the end of the weekend!
PS. I did solve the problem!
protected override object LoadPageStateFromPersistenceMedium()
{
return null;
}
As I dont need it!
