where are the field names stored?

Hi,

in EsDatasource: where are the field names stored? In my code I only see this:

Code:

<cc1:esDataSource ID="ds_xx" runat="server" AutoPaging="True" 

        AutoSorting="True" onescreateentity="ds_xx_esCreateEntity"

        onesselect="ds_xx_esSelect" />

but some fields were selected. Where are they stored? Sometimes I would like to change the field list,

and the gui does not allways pick them up.

Thanks,

Ron

Re: where are the field names stored?

The esDataSource merely feeds the columns to whatever it is bound to, it itself doesn't store them. Look at this sample from the ones that come with the trial version:

Code:

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <br />This is intentionally very plain and simple<br /><br />
    <div>
        <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AllowSorting="True" AutoGenerateColumns="False" CellPadding="4" DataKeyNames="EmployeeID" DataSourceID="EsDataSource1" ForeColor="#333333" GridLines="None">
            <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <Columns>
                <asp:BoundField DataField="EmployeeID" HeaderText="EmployeeID" InsertVisible="False"
                    ReadOnly="True" SortExpression="EmployeeID" />
                <asp:BoundField DataField="LastName" HeaderText="LastName" SortExpression="LastName" />
                <asp:BoundField DataField="FirstName" HeaderText="FirstName" SortExpression="FirstName" />
                <asp:BoundField DataField="Title" HeaderText="Title" SortExpression="Title" />
                <asp:BoundField DataField="BirthDate" HeaderText="BirthDate" SortExpression="BirthDate" />
                <asp:BoundField DataField="City" HeaderText="City" SortExpression="City" />
            </Columns>
            <RowStyle BackColor="#EFF3FB" />
            <EditRowStyle BackColor="#2461BF" />
            <SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
            <PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
            <HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
            <AlternatingRowStyle BackColor="White" />
        </asp:GridView>
        <br />

        <cc1:esDataSource ID="EsDataSource1" runat="server" AutoPaging="True" AutoSorting="True"
            OnesCreateEntity="EsDataSource1_esCreateEntity" OnesSelect="EsDataSource1_esSelect" />
    
    </div>
    </form>
</body>
</html>

Notice how the grid has the columns ...
