Request.Form["lblJobCity"].ToString();

Request.Form["lblJobCity"].ToString(); actually gave you no result? Not a null reference exception? — Andrew Barber

I think we need to see your <form> tag. Oh, and by the way; You can't use Request.Form to access the information on the <label> at all. And finally; do you have ViewState disabled? — Andrew Barber

i'm unable to use <form> because not submitting the entire form.and can i get the values without using form tag? @Anderw — user1943217

Do put some values in the controls: E.g.

<input id="txtDateTime" runat="server" value="2014-12-12" type="text" datetime="datetime"/>
<label id="lblJobCity" runat="server">Some Text goes here </label>

Then txtDateTime.Value and lblJobCity.InnerText will provide data server-side

UPDATE Here's complete form to make it work:

<form id="form1" runat="server">

   <input id="txtDateTime" runat="server" value="" type="text" datetime="datetime"  />
   <label id="lblJobCity" runat="server">Seattle</label>

   <input type="submit" id="submit" runat="server" onserverclick="submit_ServerClick" />
</form>

And then check the values in the event:

protected void submit_ServerClick(object sender, EventArgs e)
{
    string a = txtDateTime.Value;
    string b = lblJobCity.InnerText;
}

then i'm getting the data i've given in html not the value i entered in input

Input should appear as well, but on submit. E.g. add <input type="submit" /> to those controls and check values upon clicking button (I've updated my answer to a small runnable sample)

Isn't the submit_ServerClick a control?

user1943217 Over a year ago

plz see my edited answer i'm using jquery AJAX to communicate with code behind

Comfortably Numb Over a year ago

submit_ServerClick is an event handler for submit button. But @user1943217 heavily modified the question, there wasn't any mention of AJAX before. Or form construct. So I sense downvotes coming.
