Solution 1

Try :

C#

st=Superuserid1.Text.ToString()

or only

C#

st=Superuserid1.Text

Solution 3

May Be their is a problem With dataBinding to DropDown list in the Method

SQL

Loademployeegeofencee(object strUnitNo),

Are u setting the Values of

C#

Superuserid1.DataTextField="Text";
Superuserid1.DataValueField = "CorrespondingValues";

in that method..?

Make sure of it, otherwise it will not set the Value property;

Solution 4

You have to bind the data 1st only,
not in the postback
so,try this

C#

if (!IsPostBack)
{
 Loademployeegeofencee(strUnitNo);

 }
