You can use Java script if you are using VB.Net as a language.

function checkSelect()
if (document.getElementById('<%=ddlSte.ClientID %>').value == 'Select One')
document.getElementById('<%=StGoBtn.ClientID %>').disabled = true;
document.getElementById('<%=StGoBtn.ClientID %>').disabled = false;

Use this function.

So if I want to use TextBoxes is it going to be possible to replace the button id with Textboxes if so How?

you can replace your textbox control Id in place of button.

document.getElementById('<%=yourTextboxId.ClientID %>').disabled = true;
