Dynamically change HTML (PARAM) value in VB.NET

[Kevin Spencer]

Did you create an HtmlGenericControl in your CodeBehind class that the
client-side control could inherit?

Well, I tried this: "Dim MyControl as new HtmlGenericControl" (same name as
the OBJECT). Is this what you mean? Can you clarify?

BTW, putting "runat='server'" on this OBJECT creates some wierd GUID error
so I had to remove this.

Here's the HTML for the OBJECT:
<OBJECT id="MyNiKnob1" style="WIDTH: 144px; HEIGHT: 120px"
Classid="clsid:D9..." name="MyNiKnob1" VIEWASTEXT>
<PARAM NAME="_Version" VALUE="393218">
<PARAM NAME="_ExtentX" VALUE="3810">
<PARAM NAME="_ExtentY" VALUE="3175">
<PARAM NAME="Value_21" VALUE="0">
</OBJECT>

Here's my Page_Load event (trying to change PARAM value 'Value_21'):
Dim MyNiKnob As New HtmlGenericControl("MyNiKnob")
MyNiKnob.Attributes.Add("Value_21", "64")

Am I close?

Try this (at the class level, along with the other field declarations):

Protected MyControl As HtmlGenericControl

I just reviewed your last message. You have to include the runat=server
attribute in the tag in the page. The tag and the CodeBehind class must be
the same. The id attribute of the tag must match the name you give to your
field declaration. The Page inherits from the CodeBehind. I am able to
create a server-side OBJECT tag. What error are you getting?

"runat=server" doesn't work on my page for this control. It gives me this
error:
