Hiding Upload and Cancel button

[Jakub Wilk]

Hi,

 

I need to have access to UploadButton in silverlight RadUpload control.

In my scenerio upload is started by clicking LinkButton on aspx page.

I need to hide Upload and Cancel buttons in silverlight RadUpload control so users can only click my LinkButton.

How can I do that?

I try RadUpload1.FindName("uploadButton") but this returns null.

 

Help please...

Sebastian

What was the answer to this.

I have a similar scenerio where I have a RadWindow in Silverlight similar to a new email message I want them to be able to select attachments using the upload control but do not want the upload and cancel buttons. Instead I want to fire the upload off when they click a send button.

Is this possible.

Hi Paul,

Below is a copy of the original message:
 

uploadandcancelbuttonvisibility.zip You can retrieve the Upload and Cancell buttons by using VisualTreeHelper: var root = VisualTreeHelper.GetChild(upload1, 0) as FrameworkElement; var uploadButton = root.FindName("UploadButton") as FrameworkElement; var cancelButton = root.FindName("CancelButton") as FrameworkElement; uploadButton.Visibility = Visibility.Collapsed; cancelButton.Visibility = Visibility.Collapsed; I am attaching my test project for further reference. Have a look at it and let me know if you have additional questions. Kind regards, Kiril Stanoev the Telerik team

Hello, I see that you have toggle button to hide/show upload/cancel buttons. How can I hide them without toggling any where.
Thank you.

Hi Omair,
 
Thank you for your interest in the RadUpload control.

Current release of the Radupload do not expose properties related to its buttons' visibility. Because of this you should care about them.

Hi,

I am using Radupload control. and i am using following assembles in my project reference
Telerik.Windows.Controls - 2010.2.924.1040
Telerik.Windows.Controls.Input - 2010.2.924.1040


 Do you guys have the Radupload expose properties related to buttons' visibility in above those versions of assembly? Because the same i want to hide upload and cancel button.


Thanks,

Hello Jai,

For version 2010.2.924.1040 there is nothing exposed to control the visibility of the buttons. In 2011 release, we switched to using Visual State Manager and the visibility of the buttons is controled with visual states. You can restyle the control and modify the states.

Hi,

Can you please provide more detail with an example that about Visual State Manager and the visibility of the buttons is controled with visual states. You can restyle the control and modify the states ?

Thanks,

Hi Jai,

If you modify the style in Expression Blend of the RadUpload control, you will see several VisualStates in Upload's control template. For example, the state when there are selected files looks like this:



These animations control the visibility of all the buttons in the upload control. You should set the value of the discrete frames to Collapsed on the buttons that you do not want to be visible in all of the states and apply the style to the upload control.

Is this still the only way of managing buttons visibility?

[Pavel R. Pavlov]

Hello Rafal,

The buttons of the RadUpload control are part of its default template. Hence, in order to customize the default look of that control, you need to extract and edit the template. You can find more information about extracting template here.
