                <MasterTableView DataKeyNames="RecordID" EditMode="InPlace" CommandItemDisplay="Top">

            <telerik:GridNumericColumnEditor ID="rgRatesCommission" runat="server" NumericTextBox-Width="50" NumericTextBox-Type="Number" NumericTextBox-SelectionOnFocus="None" NumericTextBox-Label="$" NumericTextBox-IncrementSettings-InterceptArrowKeys="false" />         
                     

bound to a list of objects where:

"RecordID" type is Integer

"DateStart" type is Date

"DateEnd" type is Date

"Commission" type is Decimal

"Revenue" type is Nullable Decimal

Clicking the "Add" button to add a new InPlace edit row generates the following error:

"Object reference not set to an instance of an object." in the method "Telerik.Web.UI.GridNumericColumn.FormatDataValue"

RadEditor - Tab and Indent for alignment

We are planning to use RadEditor for creating our well formatted documents.

We want to create Text at certain positions in the editor.
These positions need to be defined in RadEditor by Creating Tab or Indent positions.

Example -

This text is indented
and starts at certain tabbed positions!

Please let me know how I can do this in RadEditor.

thanks

AutoResize after failed validation

I noticed that after I submit a form that fails validation, my window (with autosize="true" set) does not auto-resize to account for the validation summary.

In my click event, I am trying to call autoSize() directly if IsValid id false without much success.

private void Save_Click(object sender, EventArgs e)
   {
   if (this.IsValid)
   {
   // save
   }
   else
   {
   string autoSize = "getRadWindow().autoSize(true);";
   // Register a startup script which will manually call autoSize() on radWindowActivity
   RadScriptManager.RegisterStartupScript(
   this,
   this.GetType(),
   "resizeWindow",
   autoSize,
   true);
   }

Radgrid layout problem in pageview using tabstrip

Greetings,

    
             <telerik:RadTabStrip ID="RadTabStrip1" runat="server"   
        
            SelectedIndex="0" MultiPageID="TabContainer1" Width="800px" >  
        
                <Tabs>

Transferring items in ListBox not binding properly

Hello,

I'm trying to create two ListBoxes, where items can be transferred from one ListBox to the other. The problem is that when items are transferred the items do not look like the original (they are missing the bound image).

Here is the code I am using:

<telerik:RadListBox runat="server" ID="RadActorListBoxSource" Height="400px" Width="300px"

AllowTransfer="true" AllowTransferOnDoubleClick="true" ButtonSettings-ShowTransferAll="false"

EnableDragAndDrop="true" TransferToID="RadActorListBoxDestination" SelectionMode="Multiple"

DataSourceID="LinqDataSource4" CausesValidation="false" TransferMode="Move" DataValueField="ActorId">

<ItemTemplate>

<div>

<telerik:RadBinaryImage runat="server" ID="ActorImage" Width="50px" DataValue='<%# ((Binary) Eval("ActorImage")).ToArray() %>'

AutoAdjustImageControlSize="False" />

<%# Eval("Name") %>

</div>

</ItemTemplate>

</telerik:RadListBox>

<telerik:RadListBox runat="server" ID="RadActorListBoxDestination" Height="400px"

Width="300px" EnableDragAndDrop="true" TransferMode="Move" SelectionMode="Multiple"

EmptyMessage="Please select at least one actor" CausesValidation="true" ValidationGroup="addSceneSubmit">

<ItemTemplate>

<div>

<telerik:RadBinaryImage runat="server" ID="ActorImage" Width="50px" DataValue='<%# ((Binary) Eval("ActorImage")).ToArray() %>'

AutoAdjustImageControlSize="False" />

<%# Eval("Name") %>

</div>

</ItemTemplate>

</telerik:RadListBox>

<asp:RequiredFieldValidator ID="RequiredFieldValidator8" runat="server" ControlToValidate="RadActorListBoxDestination"

ErrorMessage="Please select at least one actor" ValidationGroup="addSceneSubmit">

</asp:RequiredFieldValidator>

<asp:LinqDataSource ID="LinqDataSource4" runat="server" ContextTypeName="DataClassesDataContext"

OrderBy="Name" Select="new (ActorId, Name, ActorImage)" TableName="Actors">

</asp:LinqDataSource>

Any ideas what is going on?

Thanks,
Zeyad

AsyncUpload with ProgressManager: how to stop polling the server

Hi,

I have fully ajaxified app, inside 1 dynamically loaded user control I have async upload:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUploadElementAttachments" MultipleFileSelection="Automatic"<BR>

MaxFileInputsCount="5" MaxFileSize="31457280" InputSize="50" Width="100%" OnFileUploaded="RadAsyncUploadElementAttachments_FileUploaded"<BR>

OnClientFilesUploaded="onClientFilesUploaded" OnClientFileUploading="onClientFileUploading" TemporaryFolder="" ></telerik:RadAsyncUpload>

Above I have:

<script type="text/javascript">

function onClientFileUploading() {

getRadProgressManager().startProgressPolling();

}

function onClientFilesUploaded() {

//getRadProgressManager().hideProgressAreas();

}

Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; }

</script>

Once I upload file, polling starts and contunies (I can see in Fiddler constant requests to /Telerik.RadUploadProgressHandler.ashx
When I upload another file, polling speed increases, I believe it's because getRadProgressManager().startProgressPolling(); is called again, another file upload - again, speed of polling increases.

ProgressManager and ProgressArea are in masterpage and are outside of any update panels:

<telerik:RadProgressManager ID="Radprogressmanager1" runat="server" RegisterForSubmit="false" />

<telerik:RadProgressArea ID="progressArea1" runat="server" Culture="(Default)" Height="200px" Skin="Default" Width="400px" style="position: absolute !important; top: 300px !important; left: 280px !important; z-index:10100 !important;" />

Question is:how to stop it from polling, I would like to start/stop polling manually (this will also solve poll speed increase issue, I think)?

P.S.: getRadProgressManager().hideProgressAreas(); is commented out cause progress area automatically disappears when upload has completed. Also when I load another user control polling speed drops to initial speed (first file upload case)

Thanks!

mouse scroll breaks radcombobox

In the AdvancedInsertTemplate, if you use a radcombobox, expand it, and scroll with the mouse while its expanded, the list breaks from the combobox. You can view this occurance going here:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/advancedformtemplate/defaultcs.aspx then
Edit an appointment then expand or drop down reminder or room radcomboboxes. Afterwards, scroll with your mouse while its expanded.

I believe the issue is that the radscheduler is not modal. If we can set the radscheduler to modal or not move in the background that would be great.

[BUG] get_selectedSlots

If I select a TimeSlot in javascript code, get_selectedSlots() does not update correctly.

function TimeSlotContextMenu(sender, eventArgs) {

var RadScheduler = $find("<%= RadScheduler.ClientID %>");

// RadScheduler.get_selectedSlots().length = 1

eventArgs.get_targetSlot().set_selected(true);

// RadScheduler.get_selectedSlots().length still = 1

}

I'm using 2010.3.1109.40 version.

Parent and child girds

I have a Parent RadGrid, you can click on the Rows and the child rad grid will appear. You can then go and add items to the child grid, once a new item is inserted I need to rebind the parent grid but still maintain the originally selected row.

I have the folllowing code, it rebinds the parent gird but i lose my selected row.

Protected Sub rgRiskAssessmentItems_ItemInserted(ByVal source As Object, ByVal e As Telerik.Web.UI.GridInsertedEventArgs) Handles rgRiskAssessmentItems.ItemInserted

If Not e.Exception Is Nothing Then

e.ExceptionHandled = True

e.KeepInInsertMode = True

SetMessage("Risk Assessment Item cannot be inserted. Reason: " + e.Exception.Message)

Else

SetMessage("New Risk Assessment Item has been added!")

'Make sure we get a submit button in the top grid after adding an item to the lower grid

rgRiskAssessment.Rebind()

'rgRiskAssessmentItems.Rebind()

End If

End Sub

Thanks for reading..

ContextKey + OnItemOver

Hi,
I want to change autocomplete extender from ACT with RadComboBox ( because of loading on demand and virtual scrolling ). Loading and scrolling is working correctly. But I am populating data from WebServis and I need to send additional info to webservis ( like contextKey in autocompleteextender ) - this value can be set from codebehind and I also need OnClientItemSelectedEvent ( when I hoover over item in combobox I want to show additional info about that item ).

Another thing I dont understand is: in aspx page I set parameter ItemsPerRequest, but how can I get that value in webservis??
In ace it is a parameter for web servis method - method signature ( string prefixText, int count, string contextkey ).

Is there a way how to do this??

Thanks in advance
