Vb.net Question

Add HTML5 placeholder text to a textbox .net

I have a standard input:

<asp:TextBox type="text" runat="server" id="txtSearchTerm" />

I'd like to have this render with a dynamic HTML5 placeholder. Something like:

'Code Behind
txtSearchTerm.**placeholder** = "Search " + Site.Name

So that it outputs the following HTML:

<input type="text" runat="server" id="txtSearchTerm"
placeholder="Search Site #1" />

where Site.Name = "Site #1".

txtSearchTerm.placeholder is not a property. I have it set to text and then run javascript to show/hide on focus BUT I would much rather just use the HTML5 placeholder value. How can I render this?

Please no JS/client side solutions.

You could use the Attributes collection. So you would have something like

txtSearchTerm.Attributes.Add("placeholder", "Search" + Site.Name);


txtSearchTerm.Attributes["placeholder"] = "Search" + Site.Name; // or Attributes("placeholder") if you're using vb.net
