sharad, what you asking is ambiguous. Whats the hurry to put everything in one statement? use proper punctuation mark. you need to clarify your question with small small statement so we can understand :)

There are probably 20 different ways to solve this issue. You need to get creative. Decide when the data should be inserted, and only let the insert happen at that point. If the data is inserted into the DB, show the user something, change the page, show an lol cat, anything, just make it happen!

but i am working in MVC and using json for key response below is my code so please look at this:
Here is my Html code:

htmlUrls += '<textarea id="txt' + i + '' + response[i].UrlID + '" onkeyup="Trigger('+i+',' + response[i].UrlID + ','+userid+')" onfocus="if(this.value==' + delimiter + 'Write a comment....' + delimiter + ')this.value=' + delimiter + '' + delimiter + ';" onblur="if(this.value==' + delimiter + '' + delimiter + ')this.value=' + delimiter + 'Write a comment....' + delimiter + ';" class="textbox" rows="" cols="" >Write a comment....</textarea>';

Here is my JS function :
<pre lang="cs">function Trigger(counter, urlid, userid) {

var xTriggered = 0;
$('#txt' + counter + '').keyup(function (event) {
xTriggered++;
var msg = 'Handler for .keyup() called ' + xTriggered + ' time(s).';
}).keydown(function (event) {
if (event.which == 13) {
testcommnt(counter, urlid, userid); event.preventDefault();
}

Solution 2

sorry guys above solution deleted by me,
please refer below one:
hello,

use below code:

private void textBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
// Enter (return) was pressed.
// ... Call a custom method when user presses this key.
AcceptMethod();
}
}

private void AcceptMethod()
{
//here you can write your action for insert data in database;
}

hope this will help you,
happy coding..
