Hi, I am confused how this should be implemented.

 I want to use the Attributes.Add("OnClick", "value goes here...") in the codebehind and I am confused if I need to add the code for the render part?

 Example, I want to add the attributes.add name and value on the anchor control: 

1    Protected Overrides Sub Render(ByVal output As System.Web.UI.HtmlTextWriter)
2            'output.AddAttribute(HtmlTextWriterAttribute.Onclick, Page.ClientScript.GetPostBackEventReference(Me, String.Empty))
3            If ImagePosition = ImagePositionModes.left Then
4                If String.IsNullOrEmpty(Url) = False Then
5                    output.AddAttribute(HtmlTextWriterAttribute.Href, Url)
6                    If TargetSelection <> Nothing Then
7                        output.AddAttribute(HtmlTextWriterAttribute.Target, TargetSelection.ToString)
8                    ElseIf TargetString <> String.Empty Then
9                        output.AddAttribute(HtmlTextWriterAttribute.Target, TargetString.ToString)
10                   End If
11                   output.AddAttribute(HtmlTextWriterAttribute.Title, LinkTitle)
12                   output.AddAttribute(HtmlTextWriterAttribute.Class, CssClass)

		add the rendered attributes.add code here?????
13                   output.RenderBeginTag(HtmlTextWriterTag.A)
14               End If
15               If String.IsNullOrEmpty(ImgUrl) = False Then
16                   output.AddAttribute("name", UniqueID)
17                   output.AddAttribute(HtmlTextWriterAttribute.Align, TextPosition.ToString)
18                   output.AddAttribute(HtmlTextWriterAttribute.Src, ImgUrl)
19                   output.AddAttribute(HtmlTextWriterAttribute.Border, "0")
20                   output.AddAttribute(HtmlTextWriterAttribute.Alt, ImageTitle)
21                   output.AddAttribute(HtmlTextWriterAttribute.Width, Width.ToString)
22                   output.AddAttribute(HtmlTextWriterAttribute.Height, Height.ToString)
23                   output.RenderBeginTag(HtmlTextWriterTag.Img)
24               End If

  Thanks for any help with this.

Ok, I know I am close to something because I was looking at the properties and methods and came acrosss

Me.Attributes.Render(output)

 however that is writing to the output, instead of adding it as an attribute towards the anchor, which I need to happen...

I believe I found the answer! 

Dim keys As IEnumerator = Me.Attributes.Keys.GetEnumerator
                Do While keys.MoveNext
                    Dim key As String = CStr(keys.Current)
                    output.AddAttribute(key, Me.Attributes(key))
                Loop
