input button causes RequiredFieldValidator to fire

Question

I have an input button on my page that is dynamically created, every time I press it, it fires the RequiredFieldValidator for the blank field in the email address. is there a way to ovverride it?

input code:

<input class=\"hledat\" id=\"searchbutton\" type=\"image\" src=\"search-button.gif\" value=\"{0}\" onclick=\"search('{1}');\" onkeypress=\"search('{1}');\"/>"

validator code:

<asp:TextBox runat="server" ID="txtEmail" ClientIDMode="Static" Width="98%" />
<asp:RequiredFieldValidator runat="server" ControlToValidate="txtEmail" ErrorMessage="email"
    Display="dynamic" ValidationGroup="newsletter" />
<asp:RegularExpressionValidator runat="server" ControlToValidate="txtEmail" ErrorMessage="email"
    ValidationExpression="\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" Display="dynamic"
    ValidationGroup="newsletter" />

What does `search`? Apart from that, "black field" means "blank field"? I assume you want to postback without validating, don't you? — Tim Schmelter, Apr 17 '12 at 08:14
are you trying to perform any JS operation in this with Search? — coder, Apr 17 '12 at 08:15
actually no, should I try to create a server button instead ? — Moran Monovich, Apr 17 '12 at 08:19
it kicks the validator because a click on the `input` causes a postback. It's unclear from your question whether you actually want it to postback or whether you just want it to do the js on the `onclick` handler. Can you clarify this? — Bazzz, Apr 17 '12 at 08:26

Make it server side button by writing runat="Server" attribute and make a CausesValidation="true|false" on your requirements. If you do false it will not validate. Do let me know if it solves the problem

HtmlButton.CausesValidation Property

Mark UP

<button causesvalidation="false" /><button ID="StateQueryButton" CausesValidation="False" runat="server"> Submit </button>

yes, i want it to do a postback

HtmlButton.OnServerClick Method

Code Behind

protected void FancyBtn_Click(object sender, EventArgs e)
{  

}

Mark Up

<button causesvalidation="false" /><button ID="StateQueryButton" CausesValidation="False" OnServerClick=" FancyBtn_Click" runat="server" > Submit </button>

try to add runat="server" to input button as shown:

*Note* the runat="server". While asp:button probably renders similarly, if what you really want it an HTML button input, you can use that. Yes, ASP.NET will pick up the value on the server side.**

<input type="button" runat="server" id="btnTest" value="change" onclick="doPostBack('btnTest', '');"/>
