Hello Daniweb!
I'm an amateur programmer who's learned quite a bit from online references, and usually searching eventually reveals the problem but I'm stuck!
I've overcome many obstacles when creating a custom button on the Ajax Editor control, namespace issues, registring the controls properly etc. I resist the temptation to ask for help because the errors should lead me in the right direction. Now I get no errors, but the control isn't visible! The tag is in the .ASP page and I even set the width, height and visible tags in case it's being hidden but nothing shows up.
This is my MaintainKB.aspx

var e = window.event || arguments.callee.caller.arguments[0];
}
var scrolledV = scrollV();
var scrolledH = (navigator.appName == 'Netscape') ? document.body.scrollLeft : document.body.scrollLeft;

function scrollV() {
var scrolledV;
if (window.pageYOffset) {
scrolledV = window.pageYOffset;

else if (document.documentElement && document.documentElement.scrollTop) {
scrolledV = document.documentElement.scrollTop;
}
else if (document.body) {
scrolledV = document.body.scrollTop;
}
return scrolledV;
}
</script>
</asp:Content>
And here is the KBCustomHtmlEditor.vb file where I modify my control.
Imports AjaxControlToolkit.HTMLEditor
Namespace MyControls
Public Class KbCustomHtmlEditor
Inherits Editor
Private Shared _editorBlogID As Integer = -1
Public Shared Property EditorBlogID() As Integer
Get
Return _editorBlogID
End Get
Set(value As Integer)
_editorBlogID = value
End Set
End Property
Protected Overrides Sub FillTopToolbar()
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Bold())
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Italic())
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Copy())
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Cut())
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Paste())
TopToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.Redo())
Dim btn As New AjaxControlToolkit.HTMLEditor.ToolbarButton.MethodButton()
btn.NormalSrc = "images/upload.png"
btn.ID = "btnUplaodImg"
btn.Attributes.Add("onclick", "show();")
'this method show() is calling from user control where we add the reference
TopToolbar.Buttons.Add(btn)
End Sub
Protected Overrides Sub FillBottomToolbar()
BottomToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.DesignMode())
BottomToolbar.Buttons.Add(New AjaxControlToolkit.HTMLEditor.ToolbarButton.PreviewMode())
End Sub
End Class
End Namespace
Anyway, if anyone can point out my blunder I'd be very grateful!
