![]() Dim csm As ClientScriptManager = Page. Hastings revolutionized oil control ring design with the invention of the Hastings Flex Vent oil control ring, and it is now the accepted standard in the industry. For 100 years, Hastings Manufacturing Company has been a world power in piston ring engineering and manufacturing. When javascript code makes a call to this javascript function, it will then perform a PostBack, which will mimic the action that occurs when the "MyButton" button is clicked. When it Comes to Piston Rings, The World Comes to Us. In the file editor under the folder Appdaemon I have adjusted the file apps.yaml as follows: - helloworld: module: hello class: HelloWorld sma: module: sma class: smabridge. When the page is built, this javascript function will be available. For this I did the following: Appdaemon installed (I did not change the configuration) App daemon started. The ASP.Net code will insert javascript code in my function to perform the PostBack for the "MyButton" control. In the code-behind, I'm creating my own javascript function. The ClientScriptManager.GetPostBackEventReference Method will build the code you need to use in javascript to perform a PostBack from a particular controlīelow is an example (in VB.Net). Var argument = ((Button)(sender)).CommandArgument //"MyArgument"ĪSP.Net provides a way for you to build a call to perform a PostBack from javascript. ![]() Var target = ((Button)(sender)).ClientID //"btnNew" Then, add the following method in the code behind: protected void DoPostback(object sender, EventArgs e) If you don't necessarily want to use JavaScript, modify the button's definition like this: ![]() In the code behind, in the Page_Load method, read the Request and the Request: protected void Page_Load(object sender, EventArgs e) Modify the button definition like this (I'm already assuming that it's nested inside an UpdatePanel): In this article you will learn about the doPostBack function and how it works. All the other controls use the JavaScript doPostBack function to trigger the postback. If you want to use your JavaScript function to trigger the postback, you need to replace the OnClick with OnClientClick.
