Open SharePoint 2010 modal dialog and refresh the parent page from custom form

Objective:

1) Open a SharePoint 2010 popup and refresh the parent page when one closes it.

2) Build a custom form that at “submit event” closes the popup and refreshes the parent page.

Solution:

-          Open a Popup using “Javascript” and “SP.UI.$create_DialogOptions();”

-          Add the method “CloseCallback” using the “dialogReturnValueCallback” property

-          Add some JavaScript code inside the CloseCallback to reload the parent page, like the following example:

<a href="javascript:openModalDialog('form.aspx');">Open My Custom Form</a>

<SharePoint:ScriptLink ID="ScriptLink1" Name="sp.js" runat="server" OnDemand="true" Localizable="false" />

<script type="text/ecmascript">

    var options;

    function openModalDialog() {

        options = SP.UI.$create_DialogOptions();

        options.width = 300;

        options.height = 100;

        options.url = SP.Utilities.Utility.getLayoutsPageUrl('customdialog.htm' );

        options.dialogReturnValueCallback = Function.createDelegate(null, CloseCallback);

        SP.UI.ModalDialog.showModalDialog(options);

    }

    function CloseCallback(result, target) {

        location.reload(true);

    }

</script>

Now when you close the popup, the parent page is refreshed.

If one is working with a Custom Form and wants to close the popup and refresh the parent after the Submit,

he could have two (or more) choices:

1) If you have 1 post back only, after the submit, the you can add in the page load the following:

protected void Page_Load(object sender, EventArgs e)

        {

            if (Page.IsPostBack)

            {

                string script = "<script language='javascript'>parent.CloseCallback();</script>";

                if (!this.Page.ClientScript.IsClientScriptBlockRegistered("rKey"))

                    this.Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "rKey", script);

            }

        }

          2) If your custom form handles more than 1 post back, you can add the following code at one specific submit click event:

Context.Response.Write("<script type='text/javascript'>window.frameElement.commitPopup();</script>");

Context.Response.Flush();

Context.Response.End();
