ASP. NET 2.0-Enter key-default submit button

One of the most annoying tasks in Web development is to process "Enter key" and "Enter key" for forms. Although we provide users with the submit button, the simplest and most direct way is to enter the text and press enter to complete the submission.

ASP. NET 2.0 provides a good solution for this problem. You only need to specify the "defaultbutton" attribute to the ID of the button control to be triggered.

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

The following instanceCodeThere is a form and four panels, and there are buttons in the report and panel. Note: Which button events will be triggered when you press enter in the 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" onclick = "button5_click"/>

<Asp: button id = "btn1" runat = "server" text = "Submit" onclick = "btn1_click"/>

<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" onclick = "button#click"/>

</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" onclick = "button2_click"/>

</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" onclick = "button3_click"/>

</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" onclick = "button4_click"/>

</ASP: Panel>

</Div>

</Form>

The corresponding, sample events for the button clicks are

Protected void button#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 );
}
