Sounds like calculate_amt is a function and not a table. Is so?

Yes it is function which return an amount depending on poste and district.

Since it's a function, it looks like you are missing something.

See the details about the error here: http://www.sql-server-performance.com/2007/parameters-not-supplied-is/[^]

Description:
This error message appears when you don’t supply a value expected by a user-defined function.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Error of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. You must supply values for each parameter in a user-defind function as long as there is not default value for that parameter defined. These supplied values must explicitly or implicitly be convertible to the parameter in question.

change code to

protected void DropDownList1_TextChanged(object sender, EventArgs e)
{
SqlDataAdapter dam = new SqlDataAdapter("select * from calculate_amt where DistrictName='" + DropDownList1.Text + "' and poste='" + DropDownList2.Text + "'", con);
DataSet dsm = new DataSet();
// add this line to define table name in dataset
dsm.Tables.Add("calculate_amt");

dam.Fill(dsm, "calculate_amt");
DataView dvm = new DataView(dsm.Tables["calculate_amt"]);
txtAmt.Text = dvm[0]["amt"].ToString();
}

while using Fill second parameter is tablename and table having name like "calculate_amt" not added to dataset so resulted to error

Parameters were not supplied for the function
