  Calling JS function from code behind with parameters

  Nov 01, 2003 04:28 PM|LINK

  I need help with the following: The code behind creates hyperlink control, dynamically, in the Page_Load method. Without javascript, the .NavigateUrl property of the hyperlink control would be assigned value like this:

  hlnkControl.NavigateUrl = "mypage.aspx?myparam=123&Date=01/01/2003";

  All would be well but I need to open page mypage.aspx in a small window without toolbar, scrollbars, and a certain size. To do this I need to call a JavaScript funtion. I have two problems so far that I can't resolve: 1. I created a small JS function OpenWind() (in the HEAD section). And if I replace the NavigateUrl propert string above to the following:

  hlnkControl.NavigateUrl = "javascript:OpenWind()";
  

  When clicking on this hyperlink it tries to open page 'javascript:OpenWind()'. Which is no good. 2. Even if item 1 would work, how do I pass the parameters "myparam=123&Date=01/01/2003" and aspx page name (mypage.aspx) to the javascript function? I would appreciate any help or suggestions.

  Hi, U can implement this in a simple way using the server RegisterStartUpScript. The example is as follows. In the page_load event u can write this script block. string pagename = "SessionTest.aspx"; String scriptString = "<script language=JavaScript> function DoClick() {"; scriptString += " window.open('" + pagename + "','Sample','toolbar=no,width=190,height=190,left=500,top=200,status=no,scrollbars=no,resize=no' )}"; scriptString += "<"; scriptString += "/"; scriptString += "script>"; if(!this.IsStartupScriptRegistered("Startup")) this.RegisterStartupScript("Startup", criptString); then finally in the onload u can call this function as follows. So when the page loads the script is called and the new page opens up as required. Here the pagename variable can be assigned dynamically. This wud give u the required solution. Any doubts u can get back. Thanks Subasree G

  This is what I did. In the NavigateUrl property is this:

  javascript: window.open('','','toolbar=0,scrollbars=0,location=0,resizable=1,statusbar=0,menubar=0'); window.close()";

  The target of the hyperlink was also "_blank".
