Dynamic PlaceHolder

Posted on 2008-10-28
Last Modified: 2013-12-17

I need to create a placeholder dynamically, containing dynamical content. If I create the placeholder at design time everything is ok. If I do create a placeholder and add the table with my data to it, it doesn't show to screen. What's wrong?

protected void Page_Load(object sender, EventArgs e)

            PlaceHolder aPlaceHolder = new PlaceHolder();
            aPlaceHolder.Visible = true;

It doesn't know where to put it.  Usually I will put in a placeholder in design time and then add the controls to it dynamically.  You could place it where it should be and make it Visible = false.

You could still dynamically create PlaceHolder objects and just use your first one for where to place on page say if you have multiple placeholder objects you are creating for some reason.

Otherwise, the one on the design surface should be able to take in as many controls as you want.

I have never tried it, but guess you could try to add this to another layout style control like a panel or something.

Ah, see how little I do with design.  Guess I should just go back to my server/business objects little hole. :) Nice answer Nullable.
