Refreshing ImageEditor after custom server-side operation

We've implemented a custom server-side function which combines cropping and applying text to an image. Ultimately, our server side method saves a new version of the cropped image to the file system. We are attempting to re-render the saved, cropped image back into the ImageEditor. However, when the ImageEditor is updated after the server-side operation, the cropped image is skewed and seems to be stretched to the width and height of the original image.

I've observed that setting args.cancel = true in our server-side method causes the same behavior I've described above to occur.

What is the appropriate way to refresh/repaint the RadImageEditor after a server-side operation?

<asp:UpdatePanel ID="updtImagepanel" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<div style="height: 600px" id="designDiv" runat="server">

<table>

<tr>

<td>

<div style="height: 600px; width: 400px;">

<telerik:RadImageEditor ID="RadImageEditor" runat="server" StatusBarMode="Hidden"

Width="400px" Height="600px" OnImageEditing="Image1_ImageEditing" EnableResize="true">

<Tools>

<telerik:ImageEditorToolGroup>

</telerik:ImageEditorToolGroup>

</Tools>

</telerik:RadImageEditor>

</div>

</td>

</ContentTemplate>

</asp:UpdatePanel>

Server-Side Code:

protected void Image1_ImageEditing(object sender, ImageEditorEditingEventArgs args){

args.Cancel = true;

string fileFolder = ConfigurationManager.AppSettings["Telerik_FileUpload"];

string fileName = string.Empty;

var commandArguments =

(Dictionary<string, object>)args.ClientObjectsDictionary["commandArgument"];

if (args.CommandName == "SaveImage")

{

EditableImage editableImage = args.Image;

// Cropping Of an Image

Rectangle cropRectangle = new Rectangle(

Convert.ToInt16(commandArguments["viewportX"]) - Convert.ToInt16(commandArguments["topX"]),

Convert.ToInt16(commandArguments["viewportY"]) - Convert.ToInt16(commandArguments["topY"]),

400,

600);

editableImage.Crop(cropRectangle);

// Applying Title, Subtitle on Image

//

//Code to set variables for ApplyText method omitted for brevity

//

//Custom function to apply text to the cropped image

Image newImage = ApplyText(titlePosition, subTitlePosition, authorNamePosition, title, subtitle, authorName, editableImage);

newImage.Save(Path.Combine(fileFolder, fileName), ImageFormat.Jpeg);

RadImageEditor.ImageUrl = //path to my image

updtImagepanel.Update();

}

How do I know if AJAX call is generated by user or by code?

I'm trying to handle AJAX calls differently in ASP.NET, depending on whether they are made by the end user or through my own code.

I'm using the Telerik RAD drop down and Telerik date picker control in my page.

Both have Client events that can be triggered and handled.

Are these client events only able to be triggered via user interaction?

Measuring Download Bandwidth

I have developed a subscription based web application using ASP.NET (C#). Applicaiton is used to give user accounts to different customers to download some files from website. I want to measure the bandwidth used by each customer account during downloading.
I'm using SQL Server 2008 at the backend where the user account information as well as download history and total download size are maintained on it.
Infact I want to calculate the bandwidth used by each customer during any download file process. Each customer is assigned certain amount of bandwidth. I want to calculate this during the session of a customer, not at the website level. Something exactly like "sharing-hub.com" website.
Is there any of ASP.NET RadControls can be of help?
Any comments and suggestions are welcomed.

Css not rendering on load

I'm applying css classes to timeslots in the OnTimeSlotCreated event. I'm also only using the timeline view, and my scheduler is in an ajax panel and a radsplitter. When the scheduler initially loads, all the timeslots look blank (greyed out), but when I click the Timeline button on the top right, everything renders fine. Also, I found out that if I override the timeslot css and specify position: relative that it renders fine the first time, but is layed out on top of appointments. Here is my scheduler code and the code-behind that sets css classes. Any help would be greatly appreciated.

<telerik:RadScheduler runat="server" ID="RadScheduler1" TimelineView-NumberOfSlots="7" AdvancedForm-Enabled="false"

OnClientAppointmentClick="appointmentClick" EnableExactTimeRendering="false" SelectedView="TimelineView"

CustomAttributeNames="SRID,PhaseID" OnAppointmentContextMenuItemClicked="RadScheduler1_AppointmentContextClick"

DataStartField="StartDate" DataEndField="EndDate" DataKeyField="PhaseID" DataSubjectField="PhaseName"

DataSourceID="PhasesDataSource" AllowDelete="false" AllowEdit="true" AllowInsert="false"

OnTimeSlotCreated="RadScheduler1_TimeSlotCreated" OverflowBehavior="Scroll" EnableAjaxSkinRendering="true"

GroupBy="PhaseName" GroupingDirection="Vertical" RowHeaderWidth="150px" >

<b><%# Eval("SRID") %></b>

</AppointmentTemplate>

<AppointmentContextMenus>

<telerik:RadSchedulerContextMenu runat="server" ID="SchedulerAppointmentContextMenu">

<Items>

<telerik:RadMenuItem Text="Unschedule" Value="CommandEdit" />

</Items>

</telerik:RadSchedulerContextMenu>

</AppointmentContextMenus>

<TimelineView GroupingDirection="Vertical" NumberOfSlots="7" GroupBy="PhaseName" />

<ResourceHeaderTemplate>

<asp:Panel runat="server" ID="resoursePanel">

<asp:Label ID="Label1" runat="server" Text='<%# Eval("Text") %>'></asp:Label>

</asp:Panel>

</ResourceHeaderTemplate>

<ResourceTypes>

<telerik:ResourceType KeyField="PhaseName" Name="PhaseName" TextField="PhaseName" ForeignKeyField="PhaseName"

DataSourceID="AllPhases" />

</ResourceTypes>

</telerik:RadScheduler>

Random r = new Random();

protected void RadScheduler1_TimeSlotCreated(object sender, Telerik.Web.UI.TimeSlotCreatedEventArgs e)

{

if (e.TimeSlot.Duration.Days == 1)

{

DateTime date = e.TimeSlot.Start;

if (date.DayOfWeek != DayOfWeek.Saturday && date.DayOfWeek != DayOfWeek.Sunday)

{

int allocated = getAllocatedTime_Day(date,e.TimeSlot.Resource.Text);

if (allocated <= 0)

e.TimeSlot.CssClass += "timeslot-empty";

else if (allocated < 25)

e.TimeSlot.CssClass += "timeslot-low";

else if (allocated < 45)

e.TimeSlot.CssClass += "timeslot-mediumlow";

}

private int getAllocatedTime_Day(DateTime time,string department)

needs two clicks to open radwindow

I need a little help. I am having a problem opening a radwindow from a parent radwindow. I have a radwindow that is called from a radgrid.

<CommandItemTemplate>

<table width="100%">

<tr class="customFont">

<td align="left">

<asp:LinkButton ID="LinkButton2" runat="server" OnClientClick="openWin('/portals/0/NewSearch.aspx?AuthoringNames='); return false;" >

<img style="border:0px;vertical-align:middle;" alt="" src="/portals/0/Images/add-icon.png" />New Search</asp:LinkButton>

<asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="openWin2('/portals/0/NewPublicationList.aspx'); return false;" >

<img style="border:0px;vertical-align:middle;" alt="" src="/portals/0/Images/add-icon.png" />Import PMID List</asp:LinkButton>

<td align="left">

</td>

<td align="right">

<asp:LinkButton ID="LinkButton4" runat="server" OnClientClick="refreshGrid(); return false;" >

<img style="border:0px;vertical-align:middle;" alt="" src="/portals/0/Images/Refresh.png" /> Refresh</asp:LinkButton>

</td>

</tr>

</table>

</CommandItemTemplate>

The linkbutton calls

function openWin2(url) {

var oWnd = $find("<%=RadWindow1.ClientID%>");

var authorNames = document.getElementById('<%=HiddenField1.ClientID%>').value;

oWnd.setUrl(url + "?AuthoringNames=" + authorNames);

var oWnd = radopen("/portals/0/NewSearch.aspx?AuthoringNames=" + authorNames, "RadWindow1");

}

The linkbuton needs two click to call the function. If I change the function to oWnd.Show that it works on one click but I then can't get the parentwindow from the opened radwindow to open another window. This line totally freezes in the opened window and will not call the second window

var oWnd2 = parentRadWindowManager.open("/portals/0/QuerySaver.aspx", "RadWindow3");

and this is my originating forms radWindow code

<telerik:RadWindowManager ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" Modal="True"

runat="server" EnableShadow="true">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" Modal="true" Width="750" Height="600" OnClientClose="OnClientClose" Behaviors="Close,Move"

ReloadOnShow="true" NavigateUrl="/portals/0/NewSearch.aspx" >

</telerik:RadWindow>

<telerik:RadWindow ID="RadWindow2" runat="server" Modal="true" Width="750" Height="300" OnClientClose="OnClientClose" Behaviors="Close,Move"

ReloadOnShow="true" >

</telerik:RadWindow>

<telerik:RadWindow ID="RadWindow3" runat="server" Width="650" Height="480" Modal="true" NavigateUrl="/portals/0/QuerySaver.aspx" >

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

Is this because I have my link button on a radGrid?
I've tried to totally follow your demos but none have it starting from a radgrid.

Thanks
