how to call javascript from asp.net HyperLink control

asp.net, hyperlink, javascript

Solution

If you use a `LinkButton` instead, you can use the `OnClientClick` property to execute a JavaScript function. Using the `HyperLink` control, you can use the `NavigateUrl` property like this:

<asp:HyperLink ID="Link1" runat="server"
    Text="Click Me!"
    NavigateUrl="javascript:OpenImage('App_Themes/White/Images/thmb_screenshot_1.png');">
</asp:HyperLink>
