[Solved] Delete Button on AdvancedForm

[Alex Occhipinti]

  Yes, there is a thread about how to do this, but it uses the older style for separate insert and edit forms.  My specific problem is that when mirroring the code the Javascript refuses to fire when the object is a LinkButton (a href), but has no problem when it is a regular Button.  Does this make any sense?

Hi Alex,

Which thread have you seen? Here is a recent one:

Is this what you need?

Actually it was this one:

http://www.telerik.com/community/forums/aspnet-ajax/scheduler/adding-delete-button-to-advancededitform.aspx

  However, the link you posted is using a Button, which works fine, but looks terrible with the skinning done in the Advanced form to the save and cancel LinkButtons (background image and padding/magrins).

Markup from my AdvanceForm.ascx

                <asp:LinkButton runat="server" ID="UpdateButton" CssClass="rsAdvEditSave">
                    <span><%= Owner.Localization.Save %></span>
                </asp:LinkButton>
                <asp:Button runat="server" ID="ButtonDelete" OnClientClick="DeleteAppointment(); return false; " CausesValidation="false" Text="Remove" />
                <asp:LinkButton runat="server" ID="lnkDelete" CssClass="rsAdvEditCancel"  OnClientClick="DeleteAppointment(); return false;"
                    CausesValidation="false">
                    <span>Delete</span>
                </asp:LinkButton>
                <asp:LinkButton runat="server" ID="CancelButton" CssClass="rsAdvEditCancel" CommandName="Cancel"
                    CausesValidation="false">
                    <span><%= Owner.Localization.Cancel %></span>
                </asp:LinkButton>

  The ButtonDelete works great, but looks like crap.  The LinkButton, lnkDelete, does a post back without executing the JavaScript, so looks right, but doesn't work.

Hello Alex Occhipinti,

Please open the AdvancedForm.js file and go to line 63 or just find the line with the following content:

$("div.rsAdvancedSubmitArea a", this._formElement).attr("onclick", "");

Just comment or simply delete that line and the link button should start executing its client click event.

All the best,

  Like butter.  Thanks as always!

  Ok, now that I've digested this a bit more, I'd like to followup my question with a little more detail.  The JavaScript that I had been using is the following:

                    <script type="text/javascript">
                        function DeleteAppointment() {
                            var scheduler = $find("<%= Owner.ClientID %>");
                            var app = scheduler.get_currentAppointment();

                            if (confirm("Are you sure you want to delete this appointment?")) {
                                scheduler.deleteAppointment(app, false);
                                scheduler.hideAdvancedForm();
                            }

                            return false;
                        }
                    </script>

  The problem here, I now realize, is that the deleteAppoinment() function's second parameter determines, in the case of a recurring event, if the delete should be for a whole series or singular occurrence.  This is fine and dandy, but this code obviously does not ask the user...which is needs to. 

  Therefore, my question is...is there a way to modify this so that is gives the typical delete confirmation dialog?  Thanks.

Hello Alex Occhipinti,

You are right.

You can use this line to delete the appointment depending on the recurrence state of it:

scheduler.deleteAppointment(app, app.get_recurrenceState() > 0);

 
I hope this helps.
