Your web parts can use the UpdatePanel, which wraps the web part into an AJAX UpdatePanel control. This can easily be done by enabling the Use update panel property of any web part.
No further modifications are necessary, but the following rules should be followed:
1. If the web part uses any dynamically loaded controls, their ID must be defined:
Incorrect:
Control ctrl = this.LoadControl("~/MyControl.ascx"); if (ctrl != null) { Controls.Add(ctrl); } |
Correct:
Control ctrl = this.LoadControl("~/MyControl.ascx"); if (ctrl != null) { ctrl.ID = "myControl"; Controls.Add(ctrl); } |
2. When requesting PostBackEventReference, use Kentico's custom function instead of the default one:
Incorrect:
this.Page.ClientScript.GetPostBackEventReference(this, ""); |
Correct:
CMS.ExtendedControls.ControlsHelper.GetPostBackEventReference(this, ""); |
