Css - different colors for different detail grid in radgrid

I have a radgrid with 3 levels i want to assign 3 different colors for different levels of grid and on click of the row there should not be any change to the selected row color. i could do it for mastertable and 2nd level detail table but the same color is being assinged to the 3rd level row selection. Please find below the attached file in which blue color is the 2nd level and 3rd level is the white color.

As both the detail grids are using .rgDetailTable .rgSelectedRow classes both are sharing common properties. How can i differentiate different Detail grids with .rgselectedrow class

below is the small code that i did to achieve the first two levels of the grid.

.rgMasterTable .rgSelectedRow {
background: #c8e8a8 !important;
color:black !important;
}
.rgDetailTable .rgSelectedRow {
background:lightblue !important;
color:black !important;
how to achieve white background color if 3rd level grid row is selected. Thanks

Load image from memorystream?

Is there a way to load an image into the ImageEditor control directly from a stream? I would like to link the ImageEditor in with the upload process so that the file is not written to disk until it is saved after whatever image manipulation is required (regulations from a particular client for sensitive data).

RadGrid ASP.NET - IE issue with MultiCell selection mode

Hi guys,

I'm having an issue with MultiCell selection mode within a RadGrid.
After I select some cells, I can't select any text inside any textbox of the whole page.

You can reproduce this bug even in this official demo page:
https://demos.telerik.com/aspnet-ajax/grid/examples/functionality/selecting/cell-selection/defaultcs.aspx
(I have this kind of problem only with Internet Explorer 9+)

Any suggestion or workaround?

Thanks
Giuseppe

[Solved] AsyncUpload Invalid Characters

I am not sure if it has to do with our recent update to 2014.1.225 or if it is only recently that our Mac users have started attempting to upload files with characters that are invalid on our windows server, but errors have been occurring as a result of this. I then noticed that the latest release specifically states that such a scenario was addressed to allow the upload of these files. I updated to this version and the same errors continue to occur. Even attempting to upload these files with invalid characters from a mac on the telerik demos do not work. The file does not succeed or fail it just sits there and throws a javascript error about an invalid token. While this is different from what we are experiencing it still seems like this does not function correctly in 2014.1.403. Is there something new that needs to be configured in order to make this work?

I have attached a screen of the errors thrown in the developer tools from our site when attempting to upload such a file in Safari on Mac. Has anyone else run into this or something similar?

Thanks!
Jon

Having issues in Telerik's RadScheduler when using recurrence fields and events

I am using RadScheduler for showing/creating the Appointments in my Database.
My code is working fine (Create, Retrieve, Update, Delete) as long as I have non-recurring Appointments. But, as soon as a recurring type Appointment comes in account, everything stops working and I get following error on postback:
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.

What am I doing wrong here?
Following is my code, On .ASPX page:

<asp:Content ID="BodyContent" ContentPlaceHolderID="MainContent" runat="server">

<telerik:RadScheduler ID="RadScheduler1" runat="server" TimeZoneOffset="00:00:00" AdvancedForm-EnableCustomAttributeEditing="true"

SelectedView="MonthView" OverflowBehavior="Expand" StartInsertingInAdvancedForm="true" EnableViewState="true"

DataKeyField="AppointmentID" DataStartField="CalendarStartDateTime" DataEndField="CalendarEndDateTime"

DataSubjectField="AppointmentBody" DataRecurrenceField="RecurrenceRule" DataRecurrenceParentKeyField="ParentAppointmentID"

DataReminderField="Reminder" OnAppointmentCreated="RadScheduler1_AppointmentCreated" OnAppointmentInsert="RadScheduler1_AppointmentInsert"

OnAppointmentUpdate="RadScheduler1_AppointmentUpdate" OnAppointmentDelete="RadScheduler1_AppointmentDelete"

OnRecurrenceExceptionCreated="RadScheduler1_RecurrenceExceptionCreated" OnReminderDismiss="RadScheduler1_ReminderDismiss"

OnReminderSnooze="RadScheduler1_ReminderSnooze">

<AdvancedForm Modal="true"></AdvancedForm>

<Reminders Enabled="true" MaxAge="5"></Reminders>

<TimeSlotContextMenuSettings EnableDefault="true"></TimeSlotContextMenuSettings>

<AppointmentContextMenuSettings EnableDefault="true"></AppointmentContextMenuSettings>

</telerik:RadScheduler>

</asp:Content>

And Code on .CS page:

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

BindAppointments();

}

private void BindAppointments()

{

try

{

List<AppointmentEN> lstAppointment = AppointmentProvider.GetAppointments();

foreach (var item in lstAppointment)

{

item.RecurrenceRule = string.IsNullOrWhiteSpace(item.RecurrenceRule) ? null : item.RecurrenceRule;

item.ParentAppointmentID = item.ParentAppointmentID == 0 ? null : item.ParentAppointmentID;

}

RadScheduler1.DataSource = lstAppointment;

RadScheduler1.DataBind();

RadScheduler1.SelectedView = SchedulerViewType.MonthView;

RadScheduler1.SelectedDate = DateTime.Now;

//RadScheduler1.Visible = true;

}

catch (Exception ex)

{

}

I have found that doing EnableViewState="false" does the job, but I don't want to do that because then other functionalities like Rescource editing stops working correctly.

Bindind hidden properties between two grids

Hello together,

as this is my first post on this forums and am new to telerik components, please be gentle, if this is a dumb question. ;-)

I try to use two RadGrids which are linked together:
