[CLOSED] Error creating custom control for date picker.
Hi,
1) First of all create a new class project like Presentation and add a class Named "CustomDate.cs".
2) The main Web project contains the page "CustomDate.aspx"
When running this code, we are getting script issue like " Unable to get property 'setMinValue' of undefined or null reference".
Guide us to resolve this issue.
