C# get/set value of html input field

Question

Is it possible to get the value of the html input field (expiration) in C# after the user clicks outside of the field? And set the value from database to the html input field on page load or on refresh. Here is my code:

<ext:Panel runat="server" Border="false">
     <Content>
            <label for="expiration"> Unknown date 2 </label>
            <input id="expiration" type="text" placeholder="DD(uu)/MM(uu)/YY(uu)" class="masked" title="title" runat="server" 
                                    pattern="^(?:(?:31(\/|-|\.)(?:0?[13578]|1[02]))\1|(?:(?:29|30)(\/|-|\.)(?:0?[1,3-9]|1[0-2])\2))(?:(?:1[6-9]|[2-9]\d)?\d{2})$|^(?:29(\/|-|\.)0?2\3(?:(?:(?:1[6-9]|[2-9]\d)?(?:0[48]|[2468][048]|[13579][26])|(?:(?:16|[2468][048]|[3579][26])00))))$|^(?:0?[1-9]|1\d|2[0-8])(\/|-|\.)(?:(?:0?[1-9])|(?:1[0-2]))\4(?:(?:1[6-9]|[2-9]\d)?\d{2})$|(uu\/([1-9]|0[1-9]|1[0-9]|2[0-9]|3[0-1])\/[0-9]{1,4})|(uu\/uu\/[0-9]{1,4})|(uu\/uu\/uu)" 
                                    data-valid-example="01/05/18"> 
     </Content>
</ext:Panel>

As per @Alander 's answer, you need to add a name attribute to the input for it to get posted to the codebehind. — Erresen

It should normally be done with Request.Form["elementName"].

In this case, Request.Form["expiration"] to access its value, change your input to use name instead of id <input name="expiration" ... /> for it to work

ok but I want to get the value after the user clicks out of the field. is that possible? and also get the value from db on page load and store it in the input field

is there a reason why you must use input? a textbox with autopostback can be easier.. a RegularExpressionValidator can be used with the textbox to validate the input as well
