如何在ASP.NET 4.5中禁用对控件的验证

Question

Software :

ASP.NET Application. Visual Studio 2013.

Scenario :

I have three button: email , start project and clear . When I click on the start project button, it validates the user's input automatically. When I click clear button, it should clear any user's input.

My problem is, when I click on the clear button, it is trying to validate the user's input.

Question :

When I click on the clear button, How can I disable this validation & enable again when I click submit button?

Code sample:

<input type="email"  runat="server" id="email"/>
<asp:Button ID="btnStartProject" runat="server" Text="Start project" 
            OnClick="btnStartProject_Click" />
<asp:Button ID="btnClear" runat="server" OnClick="btnClear_Click" Text="Clear" 
            EnableClientScript="False" 
            CausesValidation="False" />

Answer 1

(I am putting my comment as an answer for this case. It might be helpful for future readers)

It is not neccessary, to disable the validation on the email button by custom coding. Changing the input type of the clear button to reset has solved my problem: <input type="reset" value="Clear"/>
