Issue Related to Dynamically Created Controls

Question

I have added Following HTML in the Form:

<asp:Table runat="server" ID="tblFlightDetails">
        <asp:TableRow>
            <asp:TableCell CssClass="ASPTableHeader">
                <dx:ASPxLabel runat="server" ID="lblFrom" Text="From" CssClass="LabelFont"></dx:ASPxLabel>
            </asp:TableCell>
            <asp:TableCell CssClass="ASPTableHeader">
                <dx:ASPxLabel runat="server" ID="lblTo" Text="To" CssClass="LabelFont"></dx:ASPxLabel>
            </asp:TableCell>
            <asp:TableCell CssClass="ASPTableHeader">
                <dx:ASPxLabel runat="server" ID="lblFlight" Text="Flight/Airline" CssClass="LabelFont"></dx:ASPxLabel>
            </asp:TableCell>
            <asp:TableCell CssClass="ASPTableHeader">
                <dx:ASPxLabel runat="server" ID="lblDate" Text="Date" CssClass="LabelFont"></dx:ASPxLabel>
            </asp:TableCell>
                   </asp:TableRow>
        </asp:Table>

Now from Serverside code.. I have added 3 rows dynamically.. when ever page gets Postback.. all dynamically added rows get disappear.. How can i get the dynamically added rows after postback??

Thanks...

Answer 1

You need to learn about the ASP.NET page life cycle .

Dynamically created controls need to be re-created on every postback. This is best done in the OnInit event handler.

Answer 2

You have to re-add those rows every time for every postback. You are responsible.

(Eventually you might get away with viewstate, but it's ugly)
