I have the below code writted on the Button click event.
SqlDataSource3.SelectCommand = "SELECT * FROM [IDMServices] WHERE Region='" + DropDownList1.SelectedValue + "' and Country ='" + DropDownList2.SelectedValue + "'";
I need to check if the above query returns any value or returns null? For this the Selected event does'nt get fired, which gives the affeted rows.
protected void SqlDataSource3_Selected(object sender, SqlDataSourceStatusEventArgs e)
int ef = e.AffectedRows;

I guess it'd be called when you bind the data to a control like:

I am not using a Gridview.

Well then you must be using some UI control to display the data correct?
Use its DataBind method.

If you are not using GridView or something like this，I think you can just use a common SqlCommand to check whether rows are effected or not by checking its count：
using (SqlCommand cmd = new SqlCommand("SELECT count(Your Primary Key Name) FROM [IDMServices] WHERE Region='" + DropDownList1.SelectedValue + "' and Country ='" + DropDownList2.SelectedValue + "'",new SqlConnection(“…………”)))
int count = (int)cmd.ExecuteScalar();
//Do what you want here…………
