I Have to perform validation like
1. is from date valid
2. is to date valid
3. is to date less than from date

Using which validation control can i achieve the task?

You would need to use the custom validator and build a regular expression to check the dates and then compare the 2 values if theyre both dates.

Sorry, Im pretty useless at regular expressions, but there are plenty of examples on the web.

Dim dtDate As DateTime

Try
    dtDate = DateTime.Parse(TextBox1.Text)
Catch
    Date is invalid
End Try

Also, Dates have built in < and > operators;

If dateA < dateB Then
  dateA comes before dateB
End If

hi
I was mainly asking about validation control because i wanted the validation to take place in client side and not in server side.
Could some help me with some code example or how to use the validation control for the above task?

For client site validation, you can use VBScript for Date validation using "isDate" function

The default functionality of Validation Controls take place client side. They produce their own java script (or vb script, depending on the settings you have it).

You can make sure of this by setting a Validation Controls EnableClientScript property to true.

As for dates.. you can use the Compare Validator Control to compare dates and display errors appropriately by setting the Type property to ValidationDataType.Date and then setting the Operator property appropriately.
