hi all,
Please see the following code

XML

<body>
    <form id="form1" runat="server">
    <asp:Panel ID="Panel1" runat="server" Width="100" Height="300" BorderColor="Black"
        BorderWidth="1">
        <asp:ImageButton ID="ImageButton1" runat="server" AlternateText="Back" OnClientClick="alert('back button');"/>
    </asp:Panel>
    <br>
    <asp:Panel ID="Panel2" runat="server" Width="100" Height="300" BorderColor="Black" DefaultButton="Button2"
        BorderWidth="1">
        <asp:Button ID="Button2" runat="server" Text="submit" />
    </asp:Panel>
    </form>
</body>

Click inside the first panel and pressing enter key, the click event of back button is firing. How to avoid it?

Solution 1

[EDIT]
Set the property DefaultButton="Button2" for panel1 so that Button2 fires.

May not be the better solution but Disabling the Enter key works but depends on your requirement. see here[^]

You can use Link button instead of the Image button

XML

<asp:LinkButton ID="lnkButton1" runat="server">
    <img src="imageurl" />
</asp:LinkButton>

Solution 2

Please Replace Your button with this code

<asp:imagebutton id="ImageButton1" runat="server" alternatetext="Back" onclientclick="return call();" />

add a javascript function

function call ()
{
alert('back button');
return false ;
}
