Question

I have a drop down list that is filled with items and I don’t want the first item to be selected so how do I write a regular expression that doesn’t match it (excludes it, triggers an error) in asp.net.

Answer 1

you can use requirefield validator….

Code For .Aspx File-

<asp:DropDownList ID="ddl_season" runat="server"  CssClass="pagedropdown">
                 </asp:DropDownList></td>
                  <td style="width: 10px; height: 46px;" align="left" valign="top" >
                  <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="ddl_season"
                      ErrorMessage="Select Season">*</asp:RequiredFieldValidator> 

Code For .CS File-

ddl_season.Items.Add(new ListItem("--Select one--", ""));    
ddl_season.Items.Add(new ListItem("John Player", "JP"));    
ddl_season.Items.Add(new ListItem("Miss Player", "MP"));    
ddl_season.Items.Add(new ListItem("WillsClassic", "WC"));
