What is the problem you are having?
There are only 10 types of people in the world, those who understand binary and those who don't.

At first your question was not clear. But after adding few characters I got it. Always post your question clearly.
You should customize the control. Check this article(and you could fine bunch more in Codeproject)
DropDown and MultiselectDropDown Controls for ASP.NET[^]
Or alternatively you could use ListBox[^]

How can i see if Ok or cancel is pressed?
Code:
Private Sub GridView1_RowCommand(sender As Object, e As GridViewCommandEventArgs) Handles GridView1.RowCommand
If (e.CommandName = "DelUser") Then
Dim index As Integer = Convert.ToInt32(e.CommandArgument)
Dim row As GridViewRow = GridView1.Rows(index)
Dim cmd As SqlCommand = New SqlCommand("DELETE [dbo].[MOVIuser] " & _
"WHERE ID = @U_ID ", conn)
cmd.Parameters.Add("@U_ID", SqlDbType.Int)
Dim message As String = "Möchten Sie den Benutzer " & _
CStr(row.Cells(3).Text) & ", " & CStr(row.Cells(4).Text) & " wirklich löschen?"
Dim sb As New System.Text.StringBuilder()
sb.Append("<script type = 'text/javascript'>")
sb.Append("window.onload=function(){")
sb.Append("return confirm('")
sb.Append(message)
sb.Append("')};")
sb.Append("</script>")
ClientScript.RegisterClientScriptBlock(Me.GetType(), "alert", sb.ToString())
/* Which Button is pressed? */
Try
conn.Open()
cmd.Parameters("@U_ID").Value = CInt(row.Cells(1).Text)
Catch ex As Exception
Finally
conn.Close()
End Try
End If
End Sub

Did you look at the sender object that calls the sub?
Oh, your talking about the Javascript.
You can't do it that way.
More like
Button calls JavaScript first by using a click event assigned to the button. if true is returned then the called function runs and deletes the user.
ASP.Net Button Code
OnClientClick="return deleteUser();"
Javascript Code
function deleteUser() {
if Confirm("Delete User") {
return true;
}
}

if you are looking to add scroll bar to your popup than set the css overflow property to auto...
<asp:panel style="overflow: auto;height:100%; width: 100%;" >

I was thinking for some time to try and do some home automation by building a system to manage my library of physical books.
Basically I'm thinking on building a system that automatically retreives and stores books from a shelf based on user input. Add to that, I'm also thinking on building a system that could browse through Amazon and order books for me.
I can handle the first part but I have absolutely no idea how to approach the automatic book ordering system. Now, I can imagine a dozen reasons why Amazon wouldn't want people abusing their website but I would really like to come up with something that could just grab whatever book title I tell it to look for and just do the order for me.
Is this even possible? To be fair I don't have much experience in web programming, I'm more familiar with embedded systems, desktop apps and games so I'm not sure if its feasable to write something in C# to do this or if there's some kind of API provided by Amazon that would allow me to automate the ordering process.
I know I can use POST to tell the server to accept data but I don't know if something as simple as this would work in my case.
Heck, if its not possible for Amazon, any other decent place where I can order books from would be nice.

Hi Gurus,
We have an online ballot app that has a bunch of radioButtonList with values dynamically populated from the database.
Please see screenshots below to see example ballot
Sample ballot
All values ( Candidate A, Candidate B, Write In Candidate) are all stored on the database dynamically populate the radioButtonList.
Example 1 shows the current setup.
How do I modify my script to have setup similar to example2?

The object rb1 has not been initialised; use your debugger to diagnose why this happens.
