Read HTML Control Value in CodeBehind

 First Of all Write Runat Server with html controls.

<input type="text" id="TextBox6" value="" style="visibility:hidden;" runat="server" />



And if you cannot write of edit value of textbox with javascript then Use Following code to change textbox





.

 document.getElementById('<%=TextBox6.ClientID %>').value = "Text";

If Jquery Code do not work after Postback. (Solution)

Then Add Same Jquery Ready Code in This block...

The code which exist in it will be available after postback .
But in Case of Jquery document ready, after postback it got lost.


function pageLoad(sender, args) {
        if (args.get_isPartialLoad()) {


Your Code;

}}
