How can you modify the appearance of a tooltip for a dynamically generated text box?

I need to update the tooltip for a textbox in asp.net.

TextBox objTextBox;
objTextBox = new TextBox();
if (somecondition)
{
objTextBox.ReadOnly = true;
String processorClosedTooltip ="<html><p style='font-style:italic;color:blue;'>" + 
"comments are not Editable</p></html> ";
objTextBox.ToolTip = processorClosedTooltip + "\n" + comment.ToString();
}

I would like the tooltip to be displayed in blue with an underline and italic styling.

Answer №1

If you want to customize tooltips, you'll need to create your own instead of using standard ones that cannot be styled.

  • Here is an example that utilizes pure CSS.
  • Another example showcasing CSS
  • This one demonstrates the use of JavaScript for tooltips

Take a look at the example from the first link:

HTML:

<a class="tooltip" href="#">Critical<span class="custom critical">

CSS:

.tooltip {
        border-bottom: 1px dotted #000000; color: #000000; outline: none;
        cursor: help; text-decoration: none;
        position: relative;
    }
    .tooltip span {
        margin-left: -999em;
        position: absolute;
    }
    
    // Rest of the CSS rules and styling properties go here

As previously mentioned by guymin, customizing a default tooltip is not feasible due to lack of support.

If you're looking for JS controls with options for fancy tooltips, check out this library that offers a variety of choices.
