Question

How do I put a hint placeholder inside a asp TextBox   When I say a hint I mean some text which disappears when the user clicks on it  Is there a way to achieve the same using html   css

Adding placeholder attributes from code-behind:

txtFilterTerm.Attributes.Add("placeholder", "Filter" + Filter.Name);

Or

txtFilterTerm.Attributes["placeholder"] = "Filter" + Filter.Name;

Adding placeholder attributes from aspx Page

<asp:TextBox type="text" runat="server" id="txtFilterTerm" placeholder="Filter" />

Or

<input type="text" id="txtFilterTerm" placeholder="Filter"/>

The placeholder attribute  You re looking for the placeholder attribute  Use it like any other attribute inside your ASP net control    lt asp textbox id  txtWithHint  placeholder  hint  runat  server   gt    Don t bother about your IDE  i e  Visual Studio  maybe not knowing the attribute  Attributes which are not registered with ASP net are passed through and rendered as is  So the above code  basically  renders to    lt input type  text  placeholder  hint   gt    Using placeholder in resources  A fine way of applying the hint to the control is using resources  This way you may have localized hints  Let s say you have an index aspx file  your App LocalResources index aspx resx file contains   lt data name  WithHint placeholder  gt       lt value gt hint lt  value gt   lt  data gt    and your control looks like   lt asp textbox id  txtWithHint  meta resourcekey  WithHint  runat  server   gt    the rendered result will look the same as the one in the chapter above   Add attribute in code behind  Like any other attribute you can add the placeholder to the AttributeCollection   txtWithHint Attributes Add  placeholder    hint
