Calling a javascript function from Page_Load in code-behind

Question

How can I call a javascript function, that is in the aspx page, from the Page_Load method, in the code-behind?

Answer 1

The easiest way is to use the page's ClientScript property. You can register some code to run when the page loads using something like

ClientScript.RegisterStartupScript(GetType(), "hiya", "alert('hi!')", true);

See http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx for more info.

This should be available from a child control by tacking "Page." onto the beginning of the code above.

Answer 2

Please try this code:

  ScriptManager.RegisterClientScriptBlock(this.Page, this.GetType(), "MyFun1", "test();", true);
