How to open ShowModalDialog of Javascript from asp.net code behind (C#). Please provide me the code if possible and one more thing which i want to mention that , i m using Script manager on my page from where i want to open the pop up.

Answer 1

call javascript function from code behind ....

ClientScript.RegisterStartupScript(GetType(),"hwa","Samplefn();",true);

write the following code ...in javascript:

function samplefn()
{
 $("#dialog-form").dialog("open");
}

the above code used to open model dialog

$(function() {
            $("#dialog-form").dialog({
                autoOpen: false,
                minHeight: 50,
                position: [300, 50],
                height: 'auto',
                width: 400,
                modal: true
            });
        }); 

otherwise you can directly open model dialog from code behind..

   ClientScript.RegisterStartupScript(GetType(),"hwa"," $('#dialog-form').dialog('open');",true);
