Hi sonia,
To split a string, use the substring method:
string.substring(start,end)
Here string is the string from which you want to extract a substring.
start is the number specifying the position of the character at which the substring begins. (The character at start itself will be included in the substring.)
end is the number specifying the position of the character at which the substring ends. (The character at end will not be included in the substring.)
Note that the first character in the string corresponds to position 0, and the last character to position string.length-1.
Examples:
'Hello'.substring(0,2) // 'He'
'Hello'.substring(0,4) // 'Hell'

Dear Sonia Gupta,
Its a ASP .NET forum ..... it is good that you post it in javascript forum of web development forum
In javascript...considering your drop down list controls ID is 'dddCountry'
.......
objDropDownList = document.getElementById('dddCountry')
int selectedIndex=objDropDownList.selectedIndex;
var SelectedText = objDropDownList.options[selectedIndex].text;
var SelectedValue = objDropDownList.options[selectedIndex].value;
... Hope it helps ... 
Thanks,

To create a select menu like dropdownlist(select)
you can use the following code:
Select a page
JavaScript
Numbers
Strings
Navigation
Colors
JavaScripter.net
Just change the menu items and the corresponding URLs to whatever you want. You can use absolute URLs (like http://www.javascripter.net) as well as relative URLs (like mypage.htm).

Use any client-side scripting language(Javascript or VB script). Alternate Use RegularExpression Validation Control.

Hi Sonia,
You can use Custom Validator control.
let you have a textbox Textbox1 and Drag a CustomValidator Control
in CustomValidator Set ControlToValidate=Textbox1
use this method to check the validation under this control.
Thaks !

Make autopostback=true of drop down list. This will post the page when drop down list changes. Handle it's selectedindexchanged event, and bind the gridview here with the required values.

Assume your button is button1. So in page load event, write something like
button1.Attributes.Add("OnClick","return MyJSFunc();");
This will add the Onclick attribute to the button. Now inside the MyJSFunc(), get textbox element and check the value. If value is ok, return true else return false.
function MyJSFunc()
{
var TxtBox = document.getElementById("YourTextboxId");
if(TxtBox.value == "")
{
alert("Enter value");
return false;
}
else
return true;
}
These are the basic things, and I recommend you to buy a book and learn how things are working.
