Render title attribute for asp.net textbox

I want to add tooltips to a form on my site. I am using the jQuery tools library. The tooltips show the content of the title attribute of an html input. 开发者_如何学JAVAIs there a way to make the asp.net textbox render out the title attribute in the html input it creates?

Since title is a global attribute, according to the W3C HTML language specifications, I would have expected a title property in the System.Web.UI.WebControls.WebControl.

However, Microsoft appears to have chosen a more 'appropriate' name for this property: Tooltip.

If you specify this property:

var label = new Label();
label.ToolTip = "tooltip";
label.Text = "text";
Controls.Add(label);

it will render:

<span title="tooltip">text</span>

which is just what you wanted.

Seeing that Tooltip is a property of the base WebControl, I assume that it will render as a title attribute for all WebControl classes.

You would do something like TextBox1.Attributes.Add("title", "Some title value");

Textbox.Attributes.Add("title","My text");

The .Attributes.Add("Attribute Name", "Attribute Value") lets you add most attributes to most controls, but always use the native property if available.

By far the easiest way is:

<asp:TextBox runat="server" title="My Title" />

Which renders

<input type="text" title="My Title" />

This also works with style etc, etc.
