asp.net 2.0-enter key-default Submit Button

asp.net

One of the most annoying things about web development is that it handles "enter key" for a form, and "Enter key" has become a user's preference for submitting a form. Although we provide the user with the Submit button, the simplest and most straightforward way is still to enter the text and return to complete the submission

ASP.net 2.0 provides a good solution for this. You only need to assign the "DefaultButton" attribute to the ID of the button control that you want to raise the event.

You can specify "DefaultButton" at both the form level and the panel level (<asp:panel> tag). When DefaultButton is specified in the form and panel, if Enter key is triggered in the panel, the

The following instance code has a form and 4 panels, with buttons in both the declarations and the Panel. Everyone note: Which button events are triggered when you enter a carriage return in a text box

<form id= "Form1" runat= "Server" defaultbutton= "BTN1" >

<div>
<asp:textbox id= "TXT" runat= "server" ></asp:TextBox>
<asp:button id= "Button5" runat= "Server" text= "Cancel"/>
<asp:button id= "BTN1" runat= "Server" text= "Submit"/>
<asp:panel id= "PNL1" runat= "Server" defaultbutton= "Button1" >
<asp:textbox id= "TextBox1" runat= "Server" ></asp:TextBox>
<asp:textbox id= "TextBox2" runat= "Server" ></asp:TextBox>
<asp:button id= "Button1" runat= "Server" text= "Button1"/>
</asp:Panel>
<asp:panel id= "Panel1" runat= "Server" defaultbutton= "Button2" >
<asp:textbox id= "TextBox3" runat= "Server" ></asp:TextBox>
<asp:textbox id= "TextBox4" runat= "Server" ></asp:TextBox>
<asp:button id= "Button2" runat= "Server" text= "Button2"/>
</asp:Panel>
<asp:panel id= "Panel2" runat= "Server" defaultbutton= "Button3" >
<asp:textbox id= "TEXTBOX5" runat= "Server" ></asp:TextBox>
<asp:textbox id= "TextBox6" runat= "Server" ></asp:TextBox>
<asp:button id= "Button3" runat= "Server" text= "Button3"/>
</asp:Panel>
<asp:panel id= "Panel3" runat= "Server" defaultbutton= "Button4" >
<asp:textbox id= "TextBox7" runat= "Server" ></asp:TextBox>
<asp:textbox id= "TextBox8" runat= "Server" ></asp:TextBox>
<asp:button id= "Button4" runat= "Server" text= "Button4"/>
</asp:Panel>
</div>
</form>

The corresponding, sample events for the button clicks are
protected void Button1_Click (object sender, EventArgs e)
{
Response.Write (Button1.Text);
}
protected void button2_click (object sender, EventArgs e)
{
Response.Write (Button2.text);
}
protected void Button3_Click (object sender, EventArgs e)
{
Response.Write (Button3.text);
}
protected void Button4_Click (object sender, EventArgs e)
{
Response.Write (Button4.text);
}
protected void Btn1_click (object sender, EventArgs e)
{
Response.Write (BTN1. Text);
}
protected void Button5_click (object sender, EventArgs e)
{
Response.Write (Button5.text);
}
