Custom ASPX forms in AJAX mode
If you're developing a custom ASPX form in AJAX mode, do the following:
- 1.In the
<form runat="server">element, add aScriptManagerat the beginning of the form and wrap all the form content in thecontenttemplateof anUpdatePanel.📌 Example1<form id="form1" name="form1" runat="server">2<asp:scriptmanager id="ScriptManager1" runat="server"></asp:scriptmanager>3<asp:updatepanel id="UpdatePanel1" runat="server">4<contenttemplate>5... form content ...6</contenttemplate>7</asp:updatepanel>8</form>Copied! - 2.Since standard
FileUploadcontrols are not supported inside theUpdatePanel, use the customWorkflowFileUploaduser control for your attachment needs. - 3.Add the following line in the page constructor to prevent an issue that can occur when updating a row in a GridView:1this.UseClientSideOptimization = false;Copied!You will see no difference at runtime, since all this does is prevent a postback when clicking the Update button and the validation fails. The
UpdatePanelalready prevents postback. - 4.Register the postback triggers either in the Page_Load event or directly in the ASPX page for each of your ASP.NET controls that perform a
postbackorsubmit to WorkflowGen.To do this in the Page_Load event:1ScriptManager.GetCurrent(this).RegisterPostBackControl(MyControlID);Copied!To do this in the ASPX page:- 1.Add a
<Triggers>element to theUpdatePanel. - 2.Add a
<asp:PostBackTrigger ControlID="MyControlID" />element for each of the controls that requires a postback trigger.
