RegisterHiddenF ield to Capture Enter Resetting Application

[Matthew Wieder]

Hi - I wanted to capture the enter button on a form since I have a
datagrid with the first column being a delete button and if someone hits
enter it deletes the first record. I coded:

private void Page_Load(objec t sender, System.EventArg s e)
{
Page.RegisterHi ddenField("__EV ENTTARGET","Som eButtonOnThePag e");

Hello Matthew,

If we have multiple buttons on a webform, the first one rendered in the browser will fire when you press the Enter button.

In this scenario, you need to add attributes to textboxes in the Page_Load event to check which Button_click event to fire.

txtText1.Attrib utes("OnKeypres s") = "return KeyPressFunctio n('button1')"
txtText2.Attrib utes("OnKeypres s") = "return KeyPressFunctio n('button2')"

Then add the following code in the .aspx page

<script language="javas cript">
function KeyPressFunctio n(buttonName)
{
if (event.keyCode == 13)
{
if (buttonName == "button1")
{
Form1.button1.c lick();
return false;
}

if (buttonName == "button2")
{
Form1.button2.c lick();
return false;
}
}
}
</script>

Summary: If you are typing in txtText1 and hit Enter, button1_click event will fire, If you are typing in txtText2 and hit Enter,
button2_click event will fire...regardle ss of what other buttons are on the page.

Thanks.

!how I can just "eat" the enter button so it doesn't do anything?
!thanks!
