Hi,

I have a telerik radWindow for upload images.
My xaml:

First Problem: the delete icon doesn´t work.

Second Problem:

I want to make validations for each item before upload starting.
So in my .cs i have:

private void RadUpload1_UploadStarted(object sender, Telerik.Windows.Controls.UploadStartedEventArgs e)

{

cataloguePagesForValidation = new Dictionary<string, string>();

cataloguePagesForImages = new Dictionary<string, string>();

try

{

foreach (RadUploadItem item in RadUpload.Items)

{

RadComboBox descriptionTextBox = item.FindChildByType<RadComboBox>();

cataloguePagesForValidation.Add(((Pages)(descriptionTextBox.SelectedValue)).Id, item.FileName);

cataloguePagesForImages.Add(item.FileName, ((Pages)(descriptionTextBox.SelectedValue)).Id);

}

catch

{

this.RadUpload.CancelUpload();

}

I have a RadComboBox for each item that i selected. For each item i must to choose a type.
So, in method RadUpload1_UploadStarted, if the radcombobox is empty or something else....i want to cancel the uploading files without clear the elements.The problem is that "this.RadUpload.CancelUpload" clear all the items.

Thanks

Hi Tarcisis,

Thank you for providing the xaml code snippet. This seems to be a modified style and template of the old RadUploadItem's style. We made a refactoring on the UI related code of the Upload and UploadItem. We added VSM and commands, which is the case with the delete command. I would recommend going through the new UploadItem template (in Blend) and updating your current style.

Regarding the validation, I would not recommend the UploadStarted event, as the upload session has already started uploading. The UploadItem has a Validate event, which will be called when the item is ready to be uploaded, so you can perform your validation there.

Cancelling the upload will clear the current session and all of the selected files. What you can do is to store the FileInfo objects of the current items in the Upload control and re-add them back to the Upload control. You can see how to add files in procedural code in the Upload in our help here.

All the best,
