Browse dialog for custom server control
<p>I have created a custom server control that inherits from Hyperlink. The output html after control is rendered is a nice looking css button with an icon.
For the icon I have a string property.</p>

<p>What i would like to do is on the source code to open "browse file dialog" for the icon  similar to NavigateUrl property dialog see screen below </p>

<p>How this can be done? </p>
