it can be done in the client side.then the page will not be refreshed. if you are using Session["toolname"] only for the ViewToolProcurement.aspx page , then better to pass it as querystring. Replace '> With );">Click and add the following javscript to the page. function showToolProcurement(toolname) { window.showModalDialog('ViewToolProcurement.aspx?t=' + toolname, 'dialogHeight:100px;dialogWidth:280px;status:no'); } here we are binding an javascript method to the click event of the anchor tag and in the showToolProcurement method show the dialog. i hope this will help you.
