This is a joke, right ? Look around you, this site has plenty of examples. In any case, no-one learns anything by getting a full program, you need to buy a book and work through it to ever get above the level that would inspire a question like that.

When ever I try to run the attached code I get the following error:
The XML page cannot be displayed
Cannot view XML input using XSL style sheet. Please correct the error and then click the Refresh button, or try again later.

On my site I am able to run ASP.NET 2.0 and on my test server I have IIS and .NET Framework Software Development Kit (SDK) installed. Could some one tell me why I can not get this to work? AS I understand it all I need do is to upload the files and that’s it.

It looks like ASP.NET isn't registered within IIS, so IIS doesn't know what to do with a request for an ASPX page.
Read this article[^] and it should tell you what to do.

Hi All,
I have created a button at runtime on form load:
Dim btnSave As New Button<br />
btnSave.BackColor = Drawing.Color.Maroon<br />
btnSave.ForeColor = Drawing.Color.White<br />
btnSave.Text = "Save"<br />
ButtonHolder.Controls.Add(btnSave)
I Have also added a code to it as :
Public Sub btnhandler_click(ByVal sender As Object, ByVal e As EventArgs) Handles btnhandler.Click<br />
Response.Write("clicked")<br />
End Sub
but this second event code does not execute when i click on the button.
Reason???
Thanks and Regards,

You haven't wired up the eventhandler to the Click event of your dynamically-created control. Use the AddHandler[^] statement to do this.

How do we do that? Like this?
AddHandler btnSave.Click, btnhandler_click(ByVal sender As Object, ByVal e As EventArgs)
this code give me error as "expression expected" by underlining the ByVal
And where do we do that?
I have also added this
Protected WithEvents btnsave As System.Web.UI.WebControls.Button
and modified the below code:
Public Sub btnhandler_click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click
Response.Write("clicked")
End Sub
Thanks and Regards,

Did you read the article? The sample code shows you how to dynamically assign an event handler to an event. You're code doesn't look anything like that in the article so it's not surprising that it doesn't work. I suggest that you implement your code in line with the article instead of just making up something that isn't even syntactically correct.
Dot Net Jantu wrote: Public Sub btnhandler_click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSave.Click

End Sub
The Handles keyword is unnecessary if the event handler is only being used for controls that are created dynamically. However, if you have a control called btnSave defined in your ASPX page then you would want to use it.

Thanks,
its working now..
I have one more problem, in the page load i have written this
Dim txtname As TextBox<br />
txtname = New TextBox<br />
txtname.AutoPostBack = False<br />
txtname.BackColor = Drawing.Color.AliceBlue<br />
txtname.BorderColor = Drawing.Color.Black<br />
nameHolder.Controls.Add(txtname)
but in the event:
Public Sub btnhandler_click(ByVal sender As Object, ByVal e As EventArgs)
' when i type "txtn" and try for intelisence, it dosent show the control.
End Sub
Regards
Thanks and Regards,

The variable txtname has been defined locally in another procedure. It doesn't have scope in your event handler procedure so it won't appear in intellisense.
To get a reference to the TextBox control that has raised the event, you need to call FindControl on the control that contains the TextBoxes. You should define some naming convention for each TextBox you dynamically create so that you have a means of obtaining a reference to each one by name.

I am doing it like this:
but its wrong. I didt understand what you wanted to say, please correct me.
dssave.Tables("dtUsers").Rows(0)("UserName") = nameHolder.FindControl(txtname.Text.Trim)
it gives an error.
Object reference not set to an instance of an object.

Yes, it will. To know why, you need to read the MSDN documentation to understand how the FindControl method works. Have you done this?

as per the msdn documentation, I have done this..
Dim name As TextBox = nameHolder.FindControl("txtname")
also I had done this
If (Not name Is Nothing) Then
' Get name's parent.
Dim myControl2 As Control = name.Parent
Response.Write("Parent of the text box is : " & myControl2.ID)
Else
Response.Write("Control not found.....")
End If
and its showing as control not found..
Thanks and Regards,

Have you actually added a control to the Controls collection of nameHolder with the ID 'txtname'?

if this is what you mean then yes.
Dim txtname As TextBox
txtname = New TextBox
txtname.AutoPostBack = False
txtname.BackColor = Drawing.Color.AliceBlue
txtname.BorderColor = Drawing.Color.Black
nameHolder.Controls.Add(txtname)
Thanks and Regards,

The description of the Control.FindControl which you said you had read, is as follows:
Searches the current naming container for a server control with the specified id parameter.
You haven't set the ID property for your control. The fact that you have declared a variable called txtname and set it with a reference to your dynamically created TextBox object is not relevent.

hey thanks it worked.
I would like to know that do i need to assign a id for the button also?
And one more thing will i have to use that find control method in each and every procedure to retrieve the vbalue of the control?
Thanks and Regards,

Dot Net Jantu wrote: I would like to know that do i need to assign a id for the button also?
You probably should do. You will need to if you want to locate instances of the Button control calling FindControl on the container object.
Dot Net Jantu wrote: And one more thing will i have to use that find control method in each and every procedure to retrieve the value of the control?
Yes, if you don't already have a reference to one of the controls you will need to call the FindControl method on the container object, passing in its ID to find it.

Apart from what you've already been told, the button needs to be created in the LoadViewState function so that it exists early enough in the page lifecycle for the viewstate to be restored and the event to fire.

I learning and have a problem this topic. Here is what I'm tryig to figure out in my head. I need to pass a function the name "Joe" and then have the function look it up in the database and return it back so it can go inside a text vale.
Here is the example I'm work through. I can't seem to get it to work so I need to make sure I understand how to pass arguments and return them.
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim name as String = "Joe"
Dim Userid as Integer
GetUserID(name, result_sUserID)
result_sUserId = txtUserid.text
End Sub
Public Function GetUserID(ByVal name As String, result_sUserID As Integer) As Integer
.... datbase connection stuff
.... userid as int32 in database
sUserID = Convert.ToInt32(myCommand.ExecuteScalar())
Return
Result_sUserID = sUserID
End Function

The second argument to GetUserID is unnecessary as your function only needs to return 1 value. Change Return to Return sUserID and remove the following line. Modify the calling code to assign the value returned by the function to a variable.

So I do that
GetUserID(Subdomain)
'Populate lblUserId with result_sUserID
Dim sUserID As Integer
sUserID = lblUserID.Text
sUserID = Convert.ToInt32(myCommand.ExecuteScalar())
objConnection.Close()
Return sUserID
and I get the following error message:
[FormatException: Input string was not in a correct format.]
