Abhishek It depends how is your page designedif you have a masterpage the contentplaceholderid would be prefixed before textbox name. If you have a panel within which your text box is placed the panelid would be added. Better if possible share your code. It will give a better idea.

Hi Abhshek Share your complete source code . If you are using html controls then you must specify post action explicitly.

@Sumit Jolly Sir its a HTML control not a ASP's. And HTML control have no Text property.

As you have used runat=server and it is an input type control rather than WebControl you can access the textbox on server side like emailBox.Value. If you still wish to access textbox using Request.Form you can use it but as it is set as runat=server the name attribute for textbox generated would be different from design view. Check it in view source of page
