Question

I want to execute a javascript function in a c# code. Here is what i did:

string jscript = "$(function () { $('#dialog-modal').dialog('open'); });";
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "clientScript", jscript, true);

ive no idea what to do, i didnt understand how this method works

thanks 🙂

obs.: i just write “clientScript”, but i dont know how it works

My Javascript:

<script type="text/javascript">
$(function () {

            $("#dialog:ui-dialog").dialog("destroy");

            var fancyboxInitOld = jQuery("#dialog-modal").dialog({
                autoOpen: false,
                height: 200,
                width: 370,
                modal: true

            });
            fancyboxInitOld.parent().appendTo(jQuery("form:first"));


        });
</script>

My C# code

try
        {
            client.Send(message);
        }
        catch
        {
            string jscript = "$('#dialog-modal').dialog('open');";
            Page.ClientScript.RegisterStartupScript(this.GetType(), "clientScript", jscript, true);
            }

Use RegisterStartupScriptMethod instead:

string jscript = "$(function () { $('#dialog-modal').dialog('open'); });";
Page.ClientScript.RegisterStartupScript(this.GetType(),
  "clientScript", jscript, true);

I see you did this in your catch block already. RegisterClientScriptBlock is there to render client code for later use, for instance some functions.
