Hello!

1. How can I set the temporaryFolder to be in the MemoryStream?

2. I am using the control dynamically. That is, one control has several file selection buttons. The problem is that if the user wants to cancel / remove the file that is uploading then the entire line is deleted. How can I cancel / delete only the file and not the entire line (which has a title and a select button)?

Thanks

AriaSettings for RadAsyncUpload

I'm looking to get my site up to WCAG 2.0 AA and I have a RadAsyncUpload control:

<telerik:RadAsyncUpload ID="mfUpload" runat="server" MultipleFileSelection="Automatic" RenderMode="Auto" Skin="Bootstrap"
                                                OnClientFileUploadFailed="failed" EnableViewState="false" OnClientFilesUploaded="OnClientFilesUploaded"
                                                OnClientFileUploading="OnClientFileUploading" EnableAriaSupport="true"
                                                AllowedFileExtensions="jpg,png,gif,pdf" DisablePlugins="true" OnClientFileSelected="OnClientFileSelected"
                                                OnClientFileUploadRemoved="removed"   OnClientFilesSelected="onSelect" OnClientValidationFailed="OnClientValidationFailed"
                                                OnClientAdded="added"    Localization-Select="<%$ Resources:GlobalResource, SelectTitle %>"
                                                Localization-Cancel="<%$ Resources:GlobalResource,CancelText %>"
                                                Localization-Remove="<%$ Resources:GlobalResource,RemoveText %>" EnableInlineProgress="true">

                            </telerik:RadAsyncUpload>

AriaSettings don't seem to be available and I need to set a label to the form element (upload control). I set the EnableAriaSupport=true but I don't think that's going to solve my problem.

What are my options?

putting dates on minor ticks on X axis

On C#/ASP.NET I am creating a graph that I am putting dates on X axis; however, the dates are only being displayed on the major ticks. Does RadHtmlChart have a setting to display dates on minor ticks as well ?

I am attaching a screenshot.

Thanks

clicking undo button causes IE 11 crash

At times if a user is entering content into the editor, applies formatting and then hits the undo button, at times it causes IE 11 to crash. This causes them to close IE and restart the app. This does not happen all of the time but it does happen. What would cause IE to crash by clicking the undo button?

BatchEdit get DataItem upon EditItemTemplate binding.

Hello,

I'm currently looking into using a grid with Batch Editing and custom EditItemTemplates. I'm running into a wall because I need the custom template for editing to render differently depending on the values in the DataItem object for the row that is being edited.

I've created an example that is attached, and will describe it to hopefully outline what I'm trying to do.

In a database that contains people, some people are under organizations, and within those organizations are different bosses. I've created a dictionary that contains the list of bosses for 2 organizations with Id's 0 and 1. The grid shows a list of people, and if you go to edit the boss selection for any given person I'm trying to have the drop down list display different items in the list depending on the organization id for that person.

Because the DataBinding event does not fire for custom templates that are used on the EditItemTemplate property of a TemplateColumn I'm at a loss on how to do this. I've thought of creating a new class that inherits the Control class, then overriding the Render() function in hopes that I may be able to access the DataItem through the parent hierarchy but my knowledge of the RadGrid structure isn't enough to figure this out.

Here is a simple example of my code. I've made comments in the InstantiateIn function with what I'm trying to do.

Any help would be greatly appreciated and thanks in advance.
