asp:TextBox에 type="number" 넣기

asp.net 서버 태그를 사용하여, number  타입을 사용하기

I had the same requirement for a mobile website using ASP.NET. After finding no good solution, I tried simply setting type="number" directly on the textbox. To my surprise, it worked! Incredulous, I created a simple test project to double-check. I ran this line of code in each .NET version:

<!-- this HTML tested in each .NET version -->
<asp:TextBox runat="server" type="number" />

Here are the results:

<!-- ASP.NET 2.0, 3.0, and 3.5 -->
<input name="ctl01" type="text" type="number" />

<!-- ASP.NET 4.0 and 4.5 -->
<input name="ctl01" type="number" />

Bottom line: if you are using ASP.NET 4.0 or newer, just add type="number" to your textbox.

다음과 같이 사용하면, 해당 <asp:TextBox>가 <input에type="number"로 변화하게 된다.
