Default Button for a TextBox (Data entry screen) in ASP.NET

Sometimes I get annoyed when hitting the enter key in a TextBox (say login screen) resulting in undesired effects like the wrong Button being “clicked“. After so many code tricks, I found the below method that allows you to specify a default Button to submit when the user hits the enter key in a TextBox.

When you press a key on your keyboard, the js OnKeyPress event is fired. This calls a function to which we pass the id of the button associated with the TextBox. The function gets a reference to the button and simuilates a mouse-click on the Button. We perform a browser detection because IE and Netscape have different event models. The function finally returns false so that the keypress event is cancelled (otherwise a second form submit will be raised). I tried this code with newer versions of IE 6.0/Netscape 7 it worked great!.

//client side js
function clickButton(e, buttonid){
var bt = document.getElementById(buttonid);
if (typeof bt == 'object'){
if(navigator.appName.indexOf("Netscape")>(-1)){
if (e.keyCode == 13){
bt.click();
return false;
}
}
if (navigator.appName.indexOf("Microsoft Internet Explorer")>(-1)){
if (event.keyCode == 13){
bt.click();
return false;
}
}
}
}

//code behind
TextBox1.Attributes.Add("onkeypress", "return clickButton(event,'" + Button1.ClientID + "')");

The code behind generates the following code:

< input name="TextBox1" type="text" id="TextBox1" onkeypress="return clickButton(event,'Button1')" / >

This causes web control Button1 to be clicked when the enter key is hit inside TextBox1.

Better Ways to Manage Your Cache in ASP.NET

Caching is one of the features in ASP.NET 1.x that most developers are familiar with. And it has helped to fuel a yearning for cache dependency in SQL Server.
