Hi,

I want to limit the number of appointment that can overlap at the same time.

I found here how to limit that when a new appointment is created. However, lets say I want to limit to 2 appointment that overlap, I create two appointments from 8 to 9 and one from 10 to 11, if I drag and Drop the 10 to 11 to 8:30-9:30, the system will not detect that the limit is reached.

When I look in the update, the appointment that I get as "sender" is the one with the old start and end, so it is not detected as being in the interval by using "

GetAppointmentsInRange"

Can you help me ?

Custom Columns in Timeline View

Hi,

I am using Rad Scheduler in timeline view by grouping vertically on a particular resource (ID). However each resource (ID) has a list of attributes that is residing in another data set. Currently I am using a Rad Grid to the left side of the Rad Scheduler to display the different attributes (please check the attached screenshot). But they are two different controls. How can I display the attributes as custom columns inside the Rad Scheduler Control?

Thanks in advance.

Regards,
Navaneeth

trial version message appearing

Hello:

I've noticed that periodically, my asp.net application will display a message stating that the telerik controls are an eval version and to click the link to buy the non demo version. i don't know why this is happening because we have purchased the actual version (i have never installed the trial version). the download link that you all emailed to me pointed me to:
RadControls_for_ASP.NET_AJAX_2008_1_515_dev.exe

i downloaded that file and installed it.
the application was written using vs.net 2008 .net framework 2.0. i referenced the telerick.web.ui dll in the "bin" folder and not the bin35 folder.

why is this happening? is there some additional file that I need to deploy to the web server to address this? again. it only happens every once and awhile.

any thoughts????

Custom Handler - OnFileUploaded not working

I'm trying to save uploaded files into a db and return the row id. I'm having significant problems with getting the uploaded files from the RadTreeView node. The application allows users to drag/drop a file onto a node. This part is working. However, on the server side, the uploadedfiles is always empty. So I implemented a custom handler and I can access and save the file at that point. However, I can not access the results object that is returned because my OnFileUploaded event is not getting fired. I need the returned file id so I can open a new window.

I have a hidden button that is clicked via the OnClientFileUploaded event by doing a postback on the hidden button.

Here's my control:

<rad:RadAsyncUpload runat="server" ID="radUpload" OnClientFilesUploaded="OnClientFilesUploaded" PostbackTriggers="btnUploadFiles"
DisableChunkUpload="false" EnableFileInputSkinning="false" UploadedFilesRendering="AboveFileInput" MultipleFileSelection="Automatic" Skin="Default" OnFileUploaded="RadAsyncUpload1_FileUploaded" OverwriteExistingFiles="true" OnClientAdded="OnClientAdded" HttpHandlerUrl="~/Tools/CustomHandler.ashx">

Is there another way to access the results object without using the OnFileUploaded event?

RadGrid Custom Filter OnTextChanged event got triggered twice

Hi There,

I am using a custom filter in my RadGrid, but when debugging I noticed that the OnTextChanged event got triggered twice. However, if I remove the AjaxSetting section, everything works fine. But I do need to config ajax settings in my application. Is there anyone to explain why this is happening? The following is the demo code. Thanks a lot.

Client side service binding, 11 empty rows ?

Hi,

i've implemented a grid databinded with a LinqToSql datasource through client side service
I followed your documentation on demos.telerik.com or telerik.com/help but the grid displays 11 empty rows. (see attached file)

Steps to reproduce:

<telerik:RadGrid ID="RadGrid1" runat="server" Width="300" AllowPaging="True" Skin="Vista" >

<MasterTableView>

<PagerStyle AlwaysVisible="true" />

<CommandItemSettings ShowAddNewRecordButton="false" />

<Columns>

<telerik:GridBoundColumn DataField="RefTransactionTypeID" HeaderText="Transaction Type ID"

SortExpression="RefTransactionTypeID">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn DataField="Wording" HeaderText="Wording"

SortExpression="Wording">

</telerik:GridBoundColumn>

</Columns>

<NoRecordsTemplate>

There are no records to display

</NoRecordsTemplate>

</MasterTableView>

<ClientSettings EnableRowHoverStyle="true">

<DataBinding SelectMethod="GetRefTransactions" SelectCountMethod="GetRefTransactionsCount" Location="Service.asmx"

SortParameterType="Linq" FilterParameterType="Linq">

</DataBinding>

</ClientSettings>

</telerik:RadGrid>

Service.asmx:

<%@ WebService Language="C#" CodeBehind="~/App_Code/Service.cs" Class="Service" %>

Service.cs:

[DataContract]

public class MyRefTransactionType

{

[DataMember]

public byte RefTransactionTypeID { get; set; }

[DataMember]

public String Wording { get; set; }

}

[WebService(Namespace = "http://tempuri.org/")]

[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]

[ScriptService]

public class Service : System.Web.Services.WebService

{

int number = 1;

[WebMethod(EnableSession = true)]

public List<MyRefTransactionType> GetRefTransactions(int startRowIndex, int maximumRows, List<GridSortExpression> sortExpression, List<GridFilterExpression> filterExpression)

{

IQueryable LinqData = DAL.getTransactionTypes(); // LinqToSql access layer

GridLinqBindingData data = RadGrid.GetBindingData(LinqData, startRowIndex, maximumRows, "", "");

var result = data.Data.OfType<DAL.RefTransactionType>().Select(t => new MyRefTransactionType()

{

RefTransactionTypeID = t.TransactionTypeID,

Wording = t.Wording

}).ToList();

number = result.Count;

return result;

}

[WebMethod(EnableSession = true)]

public int GetRefTransactionsCount()

{

return number;

}

My thought was that was not working correctly, because the grid displays 11 empty rows, but i tried to put "return new List<MyRefTransactionType>()", the grid still displays 11 emptys rows.

On page load, the get methods are never called. (breakpoints never reached)

I'm probably doing it wrong, but i can't figure what is wrong, any help ?

Thanks.

Selected item is cleared on master row edit

We have master-detail grids very similar to the Telerik demo here.

<telerik:RadGrid ID="MasterGrid" runat="server" AllowAutomaticUpdates="True" AllowFilteringByColumn="True" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="MasterGridDataSource" GroupPanelPosition="Top" ShowGroupPanel="True">

<ClientSettings AllowColumnsReorder="True" EnablePostBackOnRowClick="True">

<Selecting AllowRowSelect="True" EnableDragToSelectRows="False" />

<Scrolling AllowScroll="True" UseStaticHeaders="True" />

<Resizing AllowColumnResize="True" AllowResizeToFit="True" EnableRealTimeResize="True" />

</ClientSettings>

<MasterTableView CommandItemDisplay="Top" DataKeyNames="OptionsID" DataSourceID="MasterGridDataSource" EditMode="InPlace" AllowMultiColumnSorting="True" ClientDataKeyNames="OptionsID" Caption="Master Grid">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" Exportable="False">

<HeaderStyle Width="28px" />

</telerik:GridEditCommandColumn>

.

</Columns>

</MasterTableView>

</telerik:RadGrid>

The problem is on master row edit, the master grid SelectedItem is unselected and the child grid is cleared.

Is there any way to keep the selection when entering edit mode?
