How to set the value of <input type = "hidden"> in asp.net page_load without using runat = "server"

Question

I need to do the following two things ...

• I want to set the value in asp.net page_load. the problem is that I do not want to use runat = "server". I tried this following but this does not work:

HtmlInputHidden hiddenControl = (HtmlInputHidden) FindControl ("a");

is there any way to access asp.net page_load without using runat = "server" ??

2. I can do this if I use, but in this case I cannot access it in the javascript function of the main page. I tried this, but it does not work ...
   • var hdnField = document.getElementById ('<% = hdnIdentity.ClientId%>');
   • var hdnField = document.getElementById ("hdnIdentity"). getAttribute ("value");
   • var hdnField = document.getElementById ("hdnIdentity"). Value

what i need ... I want to access the hidden value of the content of the page in javascript on the main page. is there any way ??? thnx pre-reviews Haroon [e-mail]

Answer 1

I sometimes do the following, especially when I want to control my identifiers (especially when using jquery).

<asp:literal id="literal1" runat="server"><input type="hidden" id="someid" value="{0}"/></asp:literal>

Then in the code you can set the value with the following:

literal1.Text = string.Format(literal1.Text, "somevalue");

It cannot do without using runat = "server", but you did not indicate why you do not want to do this. In addition, you need to get the value using request.form
