Cancelling File and IE8 Event Issue

So we will be implementing RadAsyncUpload in a few different areas in our site. However, I had a question about cancelling an upload and I also noticed what seems to be a severe issue in Internet Explorer 8:

<telerik:RadAsyncUpload ID="AsyncUpload" runat="server" TemporaryFolder="~/Uploads" CssClass="ClientFileUpload"

MultipleFileSelection="Automatic" AutoAddFileInputs="true" EnableInlineProgress="true"

ControlObjectsVisibility="RemoveButtons"

OnClientFileSelected="AsyncUpload_FileSelected"

OnClientAdded="AsyncUpload_AddClientSelection"

OnClientFileUploadFailed="AsyncUpload_UploadFailed"

OnClientProgressUpdating="AsyncUpload_ProgressUpdating" />

1. What is the best way to cancel a row from uploading its file on the client? I noticed what seem to be some internal javascript errors that get thrown no matter if I use _cancelUpload() or _stopUpdating(). To try and be the most safe I decided to find the cancel element itself and trigger a click client side, but I noticed some javascript errors from this too so I wanted to ask if this is normal? Cancelling like this:

// TODO: Instead of deleting the file input which seems to prompt the control to just force-create another

// input, cancel the upload by using the cancel element provided by Telerik. - KO 8/31/2012

//sender.deleteFileInputAt(eventArgs.get_rowIndex());

var errorRow = eventArgs.get_row();

// get the row's remove element

var cancelElement = $(errorRow).children('input')[0];

cancelElement.click();

badFile = true;

2. OnClientProgressUpdating does not seem to trigger in Internet Explorer 8. The page loads with no errors or anything indicating a problem but when I debug and try to upload a file with zero size the AsyncUpload_ProgressUpdating function shown below is never executed and the file is flagged as a green file to be uploaded on the client, which is not good for us:

function AsyncUpload_UploadFailed(sender, eventArgs) {

var errorMessage = eventArgs.get_message();

var errorCode = parseInt(errorMessage.substring(errorMessage.indexOf(":") + 1).trim());

// 0 must be code for cancelled upload

if (errorCode == 0) {

var errorRow = eventArgs.get_row();

var fileName = $(errorRow).children('span')[0].innerText.trim();

var extension = fileName.substring(fileName.lastIndexOf("."));

NotificationsWcfService.AddWarning("The file {0} has an inappropriate extension ({1})",

[fileName, extension]);

eventArgs.set_handled(true);

}

function AsyncUpload_ProgressUpdating(sender, eventArgs) {

var fileSize = eventArgs.get_data().fileSize;

// If the file size is zero then stop the upload by triggering a click on the cancel object.

// This is the only way I have found to "stop" an upload.

// This still causes javascript errors but they are the same errors that get generated from a user

// cancel click so I will assume this is the most safe. - KO 8/31/2012

if (fileSize <= 0) {

var errorRow = eventArgs.get_row();

// get the row's remove element

var cancelElement = $(errorRow).children('input')[0];

cancelElement.click();

}

RadWindow as edit dialog for RadGrid

Hi,
I'm using the techniques described here in order to use RadWindow as insert/edit dialog for RadGrid.

Now, I have several pages with this code, so I'm concerned about having to repeat the same code for all pages; I'm wondering if I can put the JavaScript code into two separate files, one for the page with the RadGrid and one for the page showed with the RadWindows in order to optimize page load and simplify pages maintenance.

Any suggestion and/or sample code will be greatly appreciated.Thank you.

un-expected behaviour on IE, when select some text and lose focus from editor

Hi,
Here, I am trying to execute radeditor command from another button control which is outside the the editor toolbox. So, I am able to execute the commands but the issue is, when we select some/all text in the editor and try to click button to apply some formatting the highlight/selection of text is clear. but when we do the same thing on Chrome, firefox, safari it works well.

To re-produce the issue,

Create a new page
Add two RadEditor controls
Run the application on IE
Enter text into first editor and select some part of text
Now, move to second editor.
See, the selection is lost.
Now, Run application on Chrome and repeat 4 & 5.
See, Selected text is still highlighted.

Or, you can test to select text in http://mono.telerik.com/Editor/Examples/ToolbarMode/DefaultCS.aspx

See the attached file for expected behaviour from IE. The snapshot is taken from Chrome.
Please look into the issue.

Regards,
Aditya Kumar

Losing controls that are added to a placeholder contrained in a form template

Hi,

I have a page that contains a grid. The grid contains a formtemplate for use when editing an item in the grid. Inside the formtemplate I have an aspplaceholder control that will be populated with a table that contains other controls. I am able to get the controls to populate in the place holder and to also populate with data. When the update command event is fired and I try to pull the values from the placeholder control the placeholder states it contains no controls. Here is a sample of the aspx page code I am using and the C# code that is used in the update command event.

<div>

<asp:PlaceHolder id="phEdit" runat="server" />

</div>

if

(((PlaceHolder)e.Item.FindControl("phEdit")).Controls.Count>0)

I have placed the code to populate the placeholder control in the itemcreated and the itemdatabound methods of the datagrid, but it still loses its controls when using the updatecommand.

Thanks

OverflowBehavior="Expand" and RadPane

Greetings,

I'm having trouble getting the Splitter/RadPane scroll to function correctly with Scheduler OverflowBehavior="Expand." Basically I want the scheduler width=100% and the height to expand/contract as required by the content.

So far I'm only able to get the scheduler's header to scroll in IE7. The rest of the content remains fixed in place. I've tried placing the scheduler inside a <div> with a set height as recommended in previous posts, but doesn't work. Seems to work ok in Firefox.

Can you please post a simple working example with overflowbehavior=expand and radpane scrolling the schduler's content?

Thanks,

Gary.

Scheduler Vanishes when closing AdvancedForm

I've been playing with the Scheduler and I've managed to get it working with a SQL database and using an Advanced Form. For some reason though when I close the form (either by clicking Save or Cancel) my Scheduler vanishes.

It save whatever I have done, but I have to refresh the page.

I've checked it against the demo and nearly everything in the .aspx page looks the same.
