Question

I want to put on DataTextField more than 1 item from database (surname and name). How can I do this?
Of course, DataTextField="surname + name" doesn’t work, but is there any possibility to put together this 2 items?

There is my code:

<asp:DropDownList runat="server" ID="dllSpecialist" DataValueField="iduserspecialist" DataTextField="surname" AutoPostBack="true" OnSelectedIndexChanged="dllSpecialist_IndexChanged" AppendDataBoundItems="true">
                        <asp:ListItem Text="" Value="0"></asp:ListItem>
</asp:DropDownList>

code behind:

    if (!IsPostBack)
    {
        dllSpecialist.DataSource = tUserSpecialistBO.getAllSpecialist();
        dllSpecialist.DataBind();
       (..)
    }

sql method:

public static DataSet getAllSpecialist()
{

    sql = "select * from tuserspecialist where del='false' and name!=''";
    return SQLTools.getDataSet(sql);
}

Answer 1

Change your SQL statement:

sql = "select surname + ' ' + name as FullName, iduserspecialist from tuserspecialist where del='false' and name!=''";

Then change your property to specify the new data item:

DataTextField="FullName"
