Id and CssClass not defined

[shapper]

Hello,

I created a custom control that inherits CompositeControl:

Public Class MySection
Inherits CompositeControl
...
Protected Overrides Sub CreateChildControls()
...
MyBase.CreateChildControls()
Me.ChildControlsCreated = True
End Sub

End Class MySection

When I use this control I define its ID and CssClass.
However, when I check the rendered output the ID and CssClass are not
defined.
What am I doing wrong?

Shoudn't this be working, since I am inheriting my control from
CompositeControl?

Thanks,
Miguel

Hi Shapper,

HTML output should be rendered as <span id="yourId"
class="yourclass"></span>. In addition, there's no need for setting
ChildControlsCreated to true because EnsureChildControls method does it for
you.
I'm guessing something else is causing problem, paste all the code.

Hi,

I think I found the problem. In my custom control I also have the
following:

Public Overloads Overrides Sub RenderBeginTag(ByVal writer As
HtmlTextWriter)
writer.RenderBeginTag(HtmlTextWriterTag.Div)
End Sub ' RenderBeginTag
Public Overloads Overrides Sub RenderEndTag(ByVal writer As
HtmlTextWriter)
writer.RenderEndTag()
End Sub ' RenderEndTag

I changed it to:

Public Overloads Overrides Sub RenderBeginTag(ByVal writer As
HtmlTextWriter)

With writer
If Me.ID <> Nothing
Then .AddAttribute(HtmlTextWriterAttribute.Id, Me.ID)
If Me.CssClass <> Nothing
Then .AddAttribute(HtmlTextWriterAttribute.Class, Me.CssClass)
End With
With writer
If Me.Width <> Nothing
Then .AddAttribute(HtmlTextWriterAttribute.Style, "width: " &
Me.Width.ToString)
End With

' Render begin tag
writer.RenderBeginTag(HtmlTextWriterTag.Div)

End Sub ' RenderBeginTag

Now it is working.

Am I doing this right? Do I really need to do this?

Thanks,
Miguel

You don't need to bacause cssclass and id are rendered automatically. In
order to change default span tag to div, override TagKey property:

protected readonly overrides property TagKey() as HtmlTextWriterTag
get
return HtmlTextWriterTag.Div
end get
end property

hope this helps
