Dear all,

I have code in asp.net c# where I need to call the YesNo dialog in server side. Actually, the code will check the database and for certain condition it will ask the user does he want to continue or not? Now, I have got some functions or java scripts but all are in client side not server side. Can you please suggest the way to perform so. Thanks for your always help and cooperation.

If you did not get it yet, you never "call" any UI-related element on server side. You always do it on client side. Server side can only generate HTML text or part of it (or other resources) in HTTP response, but the UI itself always operates in the browser. What happens when the user do some action in browser, say, chooses Yes or No, depends on the purpose of handling this event. Sometimes everything happens on the client side. Everything else is performed through another HTTP request, always. This request could request the same or new URI, or send a request via a Web form (also with some or another URI called "action") or, importantly, Ajax HTTP requests. Assuming your "check the database" is performed on the server side (which is the most reasonable way), you need to generate another HTTP request in one of these ways.

So, we are getting back to client-side (!) UI and hence JavaScript. The simplest way to request confirmation is calling confirm:

JavaScript

var confirmation = confirm("Do you want to continue?");
if (confirmation) sendSomeHttpRequest(/* ... */);

The only problem, the dialog will show not "Yes"/"No", but "OK"/"Cancel" (the "if" branch with the call shown above will execute after the press on "OK"), which could be fine in most cases.

For more serious features and flexibility, you can use jQuery Dialog (highly recommended). You can see how it works here: http://jqueryui.com/dialog[^].

But I would add: requesting a user for something is usually not the best design, by far. But suggesting the alternatives need going into much finer detail of the problem.

Here is another solution and it works

XML

//code similar to following need on button click
if (some conditional expression is true)
{
                    mpeConfirmation.Show();  //please make note of this
                    return;
}

//Following I have defined in Markup and gets displayed from server-side as mentioned in the code snippet above

<asp:Panel ID="pnlConfirmation" runat="server" Width="600px"  Style="display: none" EnableViewState="true">
            <div runat="server" id="divConfirmation" class="ModalPopupHeader">
    Confirm?
            </div>
            <uc:Confirmation ID="ucConfirm" runat="server" />
        </asp:Panel>
        <asp:Button ID="btnDummyConfirmation" runat="server" Style="display: none;" />
        <ajaxToolkit:ModalPopupExtender ID="mpeConfirmation" runat="server" BehaviorID="mpeConfirmationBehavior"
            TargetControlID="btnDummyConfirmation" RepositionMode="None" PopupControlID="pnlConfirmation"
            PopupDragHandleControlID="divConfirmation" DropShadow="true" BackgroundCssClass="modalBackground">
</ajaxToolkit:ModalPopupExtender>

ucConfirm is a UserControl created with required layout and buttons. 'Yes', 'No' I have defined two events inside this control like follows

  /// <summary>
       /// Event for On OK button clicked
       /// </summary>
       public event EventHandler OKClicked;

       /// <summary>
       /// Event for On Cancel button clicked
       /// </summary>
       public event EventHandler CancelClicked;


private void OnOKClicked(object sender, EventArgs e)
       {
           if (OKClicked != null)
           {
               OKClicked(sender, e);
           }
       }

       private void OnCancelClicked(object sender, EventArgs e)
       {
           if (CancelClicked != null)
           {
               CancelClicked(sender, e);
           }
       }

       protected void btnOk_Click(object sender, EventArgs e)
       {
           OnOKClicked(sender, e);
       }

       protected void btnCancel_Click(object sender, EventArgs e)
       {
           OnCancelClicked(sender, e);
       }

I've consumed these events in the user control wherever I needed the Confirmation message functionality initiated from Server side, rather than on button client-click. Since I did not want the confirmation to show always, but only on certain condition I took this approach

Hope that helps
Thanks

Solution 4

Is this you are looking for?

VB
