I have a DropDownList with values that I get from a SQL database. Depending on the selection made from the DropDownList, I populate a GridView, also from a SQL database.

When I set AutoPostBack=true on the DropDownList I get a ‘Input string not in correct format’ error.

My DropDownList:

<html>
 <asp:DropDownList ID="ddlClient" runat="server" DataSourceID="dsClientList"                        AppendDataBoundItems="True" DataTextField="Name" DataValueField="Name" TabIndex="0" Font-Names="Verdana" Font-Size="11px" ForeColor="#2D2D2D" AutoPostBack="true">
        <asp:ListItem Value="">--- Select ---</asp:ListItem>
  </asp:DropDownList>
  <asp:ObjectDataSource ID="dsClientList" runat="server" SelectMethod="GetList" TypeName="Class.Client">
  </asp:ObjectDataSource>
</html>

In my ObjectDataSource for my GridView I use the following SelectParameters:

<SelectParameters>
<asp:ControlParameter ControlID="ddlClient" Name="pClientID" PropertyName="SelectedValue"
Type="Int32" />
</SelectParameters>

Any help?

Thanks

    You have to set numeric column for DataValueField="Name". May be an ID or Number.

    <asp:DropDownList ID="ddlClient" runat="server" DataSourceID="dsClientList"  
                     AppendDataBoundItems="True" 
                     DataTextField="Name" 
                     DataValueField="pCientID"
