Hello there.
First of all I must say that I am a newbie when it comes to net (C#).
Here is my problem.
I can not populate the DropDownList with ID="ddlName" when select the value in the DropDownList with ID="ddlMatr" and vice versa.
If you have link for similar task, please give it me.
Can you explain any one or any sample code related this.
Your help would be very appreciated.
Thanks in advance for your time and hints.
Cheers.
