[Solved] Delete Series with confirmation

Hi,

I'm handling series without exceptions.
So in other words - the user always edits the whole series (or a single appointment if no recurrence is defined).

I found a thread here how to suppress the "Series or single appointment" dialog on editing.
It suppresses the dialog - and shows the edit form for series - this is fine, but it also suppresses the delete confirmation.

I found out how to "filter between edit and delete" - but I have no idea how to go on.
What I want is a "normal" confirmation dialog "Do you want to delete the series"???

Here my code so far....

function RecurrenceActionDialogShowingHandler(sender, args) {

if (args._recurrenceAction == 1) {

args.set_cancel(true);

}

//Edit this instance only:

//args.set_editSeries(false);

//Edit the entire series:

args.set_editSeries(true);

}

It suppresses the selection for edit - but shows it for delete.

This sample of code is used to show in the selected item of a RadCombobox a IMAGE

var input = sender.get_inputDomElement()

input.style.background =

"url(" + eventArgs.get_item().get_imageUrl() + ") no-repeat";

input.style.paddingLeft = "22px";

}

function showFirstItemImage(sender) {

var input = sender.get_inputDomElement()

input.style.background =

"url(" + sender.get_items().getItem(0).get_imageUrl() + ") no-repeat";

input.style.paddingLeft = "22px";

Couldn't check multiple checkbox items

I have a saved the multiple checked items into my database, when I retrieve out the records, it only checked one item in the listbox instead of multiple. I have also verified that the records returned in the datatable contains 3 records.

aspx:
<telerik:RadListBox ID="lbxDevelopmentComponent" SelectionMode="Multiple" runat="server" OnClientItemChecked="OnClientItemChecked"
                                        CheckBoxes="true" DataTextField="Text" DataValueField="Value" Width="500px" Height="150px">
                                    </telerik:RadListBox>

.cs:
var dtDevelopmentComponent = _objSqlManager.ExecuteSQL(sqlDevelopmentComponent.ToString(), paramDevelopmentComponent);

                        if (dtDevelopmentComponent.Rows.Count > 0)
                        {
                            for (int i = 0; i < dtDevelopmentComponent.Rows.Count; i++)
                            {
                                RadListBoxItem item = lbxDevelopmentComponent.FindItemByText(dtDevelopmentComponent.Rows[0]["DEVELOPMENT_COMPONENT_NAME"].ToString());
                                if (item != null)
                                    item.Checked = true;
                            }
                        }

Set button event in code behind to open window

I need to define a button in code to open a window
This is the code I'm using
Dim img As ImageButton

For x = 0 To weekcolour.GetUpperBound(0)

columnname = "ColumnITask" + (x + 1).ToString
imagename = "btnEx" + (x + 1).ToString
If Not (img Is Nothing) Then
img.ImageUrl = "/private/images/" + weekcolour(x) + "_light_ilp.png"
             If weekcolour(x).Contains("green") Then
                    img.OnClientClick = "openRadWindow('<%# DataBinder.Eval(Container.DataItem,'" + student_id + "') %>'); return false; > """
             End If
End If
next
The code updates the image url correctly but does not add the onClientCick event
It still does not work if I remove the "if" statement
This is my open window script

<script type="text/javascript"><br><br> function openRadWindow(StudentID) {<br> var oWnd = radopen("task_update.aspx?StudentID=" + StudentID, "RadWindow1");<br> oWnd.center();<br> }<br> </script>

Clear Upload List

If I upload 3 files and then upload 2 more, the upload list shows all 5 files. I want to clear the list so only the 2 new ones show. The situation I have is that I have an upload form who's visibility is toggled on the screen. Once they upload, it is hidden. They can then go into another "folder" (all using ajax on the same page) and then show the upload portion and upload again. To them, it is a new upload but to the upload component, it is another upload and thus it shows the previous items as well as the new items.

Hiding and Sorting fields in the ConfigurationPanel

Hi there.

How can I hide certain fields in the All Fields list in the ConfigurationPanel?

I can iterate through the pvtAD.Fields collection in the pvtAD_PreRender method and find the fields I want to hide but when I use pvtAD.Fields[i].IsHidden = true; it doesn't hide it. It still appears and also the update doesn't work when I apply any config changes.

And how can I do something like this?
pvtAD.Fields = pvtAD.Fields.OrderBy(x => x.Caption).ToList();

Many thanks,
Chris
