Solution

Use

ScriptManager.RegisterStartupScript(myControlInstance, 
                                    typeof(MyControl),
                                     "key",
                                     "my javascript string here", 
                                     true);

Problem

I have an update panel load a user control, and the goal here is to have a specific JavaScript function called when this occurred. I was thinking this would be done through the Script Manager, though this does not need to be the case if there's an html alternative. The flow is basically the following: - User clicks button - Update panel loads control - Javascript function is called Many thanks I've already tried `RegisterStartupScript(..)`, though i may have made a syntactical mistake ``` if (show) { string scriptId = String.Format("{0}:script", ++uniquePopupId); string scriptTag = String.Format("showPopup({0},{1});", Width, Height); ScriptManager.RegisterStartupScript(this, this.GetType(), scriptId, scriptTag, true); } ``` Solution: ``` if (show) { string scriptId = String.Format("{0}:script", ++uniquePopupId); string scriptTag = String.Format("showPopup({0},{1});", Width, Height); ScriptManager.RegisterStartupScript(updPanelChildControl, updPanelChildControl.GetType(), scriptId, scriptTag, true); } ```
