I am trying to call from JS to C# function. I can not use ajax. I have tried to create a ASP.NET button when it clicked it calls the C# function and call the click function from JS:
<asp:Button runat="server" ID="UploadButton" OnClick="Upload_Click" />
protected void Upload_Click(object sender, EventArgs e)
The problem is that the click event from JS does not working. I have tried to write after the first line of the JS code an alert to see if the code rich to that line but I can only see "After CLICK".
