Question

I need to show every record which equals the var modid and the current session’s userid.

In .cs code this would be:

SELECT Mod_Naam 
FROM Model 
WHERE Mod_ID = " + modid + " 
AND User_ID = '" + Session["status"].ToString() + "'

How can I import this query in a dropdownlist?

I may also need to use this on a gridview.

You can get the data from a DB via the DataTable and then bind that DataTable to the dropdownlist as follows:

using (SqlCommand cmd = new SqlCommand()
    { 
        cmd.Connection = cnn;
        cmd.CommandType = CommandType.Text; 
        cmd.CommandText = "SELECT Mod_Naam FROM Model WHERE Mod_ID = " + modid + " AND User_ID = '" + Session["status"].ToString() + "' "";
       //cmd.Parameters.Add(param);// You add parameter


        using (SqlDataAdapter da = new SqlDataAdapter(cmd)) 
        { 
            da.Fill(dt); 
        }

Take a look here, on how to get Data in DataTable Retrieve a DataTable using a SQL Statement

DropDownList1.DataSourceID = dt;
DropDownList1.DataTextField= "Mod_Naam";
DropDownList1.DataValueField= "Mod_Naam";
DropDownList1.DataBind();
