ASP.NET

There is an asp.net form (vb.net). Nothing is added to the code-behind. All dynamics on the client through JQuery.
I add an "innocent" line:

<input id="txt_BranchName" name="txt_BranchName" class="HebrewInputRTL jLimit25 row_BranchName" type="text" runat="server" />

and after submit I get:

Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. bla bla bla

Whole code of the page:

Of course, it is worth removing the input and everything is submitted.
Any stackoverflow tell how to dynamically add controls. But everything is static.

Why are you adding the runat='server' attribute? Do this:
JavaScript:

 $("<intput>").attr({'name':'tbSomeName', 'type':'text'}).val('Some Value').appendTo('form')

On Postback:

var value = Request.Params.Get('tbSomeName');
