Send a variable from vb.net to javascript
Question
I have some problems when i send the value variable in visual basic net to javascript, for example: this code:
Partial Class borrador1 // The code in aspx
Inherits System.Web.UI.Page
public myVariable As string
public sub MyMethod()
myVariable ="Hello World"
end sub
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
MyMethod()
end sub
In the next part i try to recive the value in javascript
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
</head>
<body>
<script type="text/javascript">
var variable = '<%= myVariable%>';
</script>
<body>
</html>
I load the page and i see the next problem in the browser: [HttpException (0x80004005): Please, see whether wrapping the code block, generating the exception, within RadCodeBlock resolves the error.] Telerik.Web.UI.RadAjaxControl.MoveUpdatePanel(Control initiator, Control updated) +437 Telerik.Web.UI.RadAjaxControl.PerformRender() +419 Telerik.Web.UI.RadAjaxControl.OnPageRender(HtmlTextWriter writer, Control page) +1450 Telerik.Web.UI.RadAjaxControl.RenderPageInAjaxMode(HtmlTextWriter writer, Control page) +197 System.Web.UI.Control.RenderChildrenInternal(HtmlTextWriter writer, ICollection children) +131 System.Web.UI.Page.Render(HtmlTextWriter writer) +40 System.Web.UI.Control.RenderControlInternal(HtmlTextWriter writer, ControlAdapter adapter) +150 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +5363
