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

[Solved] Find UpdateButton

Hi,

since there is no "readonly appointment" I try to disable the update button in clientFormCreated.

My problem - I can't find it...

Subject works fine - button not...

function clientFormCreated(sender, args) {

var $ = $telerik.$;

var mode = args.get_mode();

if (mode == Telerik.Web.UI.SchedulerFormMode.AdvancedInsert || mode == Telerik.Web.UI.SchedulerFormMode.AdvancedEdit) {

//var rUpdButton = $telerik.findButton($("[id$='Form_UpdateButton']").attr("id")); //findButton not existing although it shows in intellisense

var rUpdBJQueryObject = $telerik.$("[id$='Form_UpdateButton']");

var rUpdBRadButtonObject = $find(rUpdBJQueryObject.attr("id")); //always null

var rSubject = $telerik.findTextBox($("[id$='Form_Subject']").attr("id"));

rSubject.disable(); //works

I guess I do something wrong..

Maximum Amount of Data

I am working with the Radscheduler and building a calendar that has dynamic data. Since I cannot control how much data comes back from the database, during testing I am trying to overload the scheduler and have succeeded in doing so. When I bind over 2,900 appointments in a month view (it should be noted that these appointments have several custom attributes) it is breaking with a message like this...

Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

I have already tried setting the maxJsonLength to it's maximum value in web.config, so I think I am maxing out this.

1) Is there any way other than what I have mentioned above to increase the amount the Radscheduler can handle?
2) Is there an official amount of data that is a recommended maximum to bind to the Radscheduler?
3) When it errors out saying maxJsonLength, why is that the error? Does this have something to do with the way data is retained within the control itself?

Set selected color to 'No Color' button

Actually, when you press the 'No Color' button, the palette sets as no color the black color.

My question is if it's possible to set as 'No Color' the white color (#ffffff).

Regards,

Alexis Rosano.
