Creating HTML Placeholder through PAPI

| Hi
Looks like you are missing a call to Databind(). Also you
may want to not set the Html property of the control on
every page load.
Check out the sample code written by Stefan that shows you
how you can add the HtmlPlaceholderControl dynamically:

| Thanks Mei. I'm getting an error.
The error I get is: Object reference not set to an instance of an object at
at
me.findcontrol("Me.FindControl("PlaceholderControlDestination").Controls.Add(htmlPh)").Controls.Add(htmlPh))
I added these lines to my code per Stefans code sample from Gotdotnet.com:
Dim PlaceholderControlDestination As HtmlControls.HtmlTableCell
htmlPh.DataBind()
Me.FindControl("Me.FindControl("PlaceholderControlDestination").Controls.Add(htmlPh)
").Controls.Add(htmlPh)
Thanks for your time.

| Hi Varad,
I assume you did not create a control with name
"PlaceholderControlDestination".
Without this the FindControl function will return null.
Cheers,
Stefan.

| Stefan I have declared it as
Dim PlaceholderControlDestination As HtmlControls.HtmlTableCell just like in
your code.

| But did you have such a control in the aspx or ascx file?
Just declaring it in the code behind file is not enough!
Please compare in my sample.
Cheers,
Stefan

| Hi Stefan
I forgot to declare the html control in the aspx page. that took me past
the error I got. But my problem is that I'm trying to get the html to display
in a placeholderbox when viewing in edit mode.
My suspicion is that even if save data through a html placeholder, when I
view it in edit mode, if the template that was used to create it doesnt have
an embedded CMS control, the data wont display in the control that was
created in the code behind page. Is that true?
Thanks

| Hi Varad,
no this is not true.
In edit mode the ActiveX editor will show up correctly.
Try my ready-to-use sample. It will show it to you.
Cheers,
Stefan.

| Thanks Stefan. I'll try your sample. Can I include your control in a web app
using VB.Net?

| Hi Varad,
it is not a control, it is a template file.
You would have to port the code behind part to VB.NET.
Cheers,
Stefan.
