• ASP.NET 4.0 Web Forms
• I want to use HTML5 number input textbox
• I’m targetting html5 modern browser, e.g. Chrome, Apple Safari

Solution

With the latest NET 4.0 update, you can override input type of asp:Textbox to any html5 type. You can use type number by adding type=”number” to asp:Textbox.

<asp:TextBox ID="TextBox1" runat="server"
  placeholder="number"
  type="number"></asp:TextBox>

It will be rendered with spinboxes as shown below in Chrome and Safari. You can check “Can I Use” for list of browsers that support input type=number.

Number Input in Chrome

Number Input in Safari

Notes
This only works after you install Update for the .NET Framework 4. And your project target framework must be NET 4.0 and above.

Feature 3
New syntax lets you define a TextBox control that is HTML5 compatible. For example, the following code defines a TextBox control that is HTML5 compatible:

<asp:textbox runat="server" type="some-HTML5-type" />

I’m still fond of ASP.NET Web Forms, and I was wondering how to implement html5 placeholder for input textbox with ASP.NET 4.0 Web Forms.

Solution

To add html5 placeholder to input textbox in ASP.NET, you only need to add attribute placeholder to asp:Textbox tag. As simple as that!

<asp:TextBox ID="placeholderTextBox" runat="server"
  placeholder="html5 placeholder"></asp:TextBox>

I didn’t verify this, but I guess you will have to install “Web Standards Update for Microsoft Visual Studio 2010 SP1” first.

Input textbox with placeholder as seen in Google Chrome 18 (May 2012).

When you run it Mozilla Firefox 12.

There are lot of major changes to framework, library, control templates, etc. The coolest addition is the inclusion of Expression Blend 4 for Windows Phone Beta.

Make sure you read What’s New in Windows Phone Developer Tools Beta after or before downloading the Beta, as your current CTP project might break. There are short tips for migrating current CTP project to Beta.

The following guidance applies only to applications created using Windows Phone Developer Tools CTP Refresh (April 2010). If you created your application using the Windows Phone Developer Tools CTP (March 2010), do not use your previous project; instead, create a new one.

1. Create a new project.
2. Copy your own code from app.xaml, but leave out any template code.
3. Do this for each page.
4. Bring in libraries as-is.
5. Fix build breaks.

For more details and thorough guide, read Jaime Rodriguez’s blog post on migration.

I do not have chance to do test installation in many system – slow installation, bla bla bla. It doesn’t allow me to install in Windows Vista without SP1 installed and I have no access to any 64-bit system. Hence I only tested on the following box:

• Operating System: Windows 7
• Platform: x86
• No prior installation of: Visual Studio 2010 RTM; Visual Studio 2010 Express; Windows Phone Developer Tools CTP March; ( I installed Visual Studio 2010 RTM after installing this, and both works fine )

Web installer can be downloaded from Microsoft Download – Windows Phone Developer Tools CTP (April Refresh). Scroll down for offline installation ISO image.
Few details that we already know. It’s an April Refresh release – which fixes compatibility issue with Visual Studio 2010 RTM.

Installed List for WPDT CTP April Refresh

Update:
Tested this installer in Windows XP. By following Aaron’s Tips, open “baseline.dat” with Notepad, look for the section named [gencomp7788], change the value InstallOnWinXP from 1 to 0. WPDT CTP can be successfully installed in Windows XP, but unfortunately we will not be able to run Windows Phone 7 Simulator as XDE is not compatible with Windows XP.

Update 2:
Latest Beta offline installer is up.
