Description

How to replace the default MS OpenFileDialog with a [RadOpenFileDialog]({%slug radfiledialogs-radopenfiledialog%}).

Solution

Handle the AddingFiles event of the RadCloudUpload control, cancel the creation of the default dialog with the CancelDialogOpening property, open a new RadOpenFileDialog and populate the FileNames collection with the files, selected in the dialog.

[C#]

{{region cs-kb-cloudupload-howto-show-radfileopendialog-1}} private void RadCloudUpload_AddingFiles(object sender, AddingFilesEventArgs e) { e.CancelDialogOpening = true;

    if (fileDialog == null)
    {
        fileDialog = new RadOpenFileDialog();
        fileDialog.Multiselect = true;
    }

    if (fileDialog.ShowDialog() == true)
    {
        foreach (var file in fileDialog.FileNames)
        {
            e.FileNames.Add(file);
        }
    }
}

[VB.NET]

{{region vb-kb-cloudupload-howto-show-radfileopendialog-1}} Private Sub RadCloudUpload_AddingFiles(ByVal sender As Object, ByVal e As AddingFilesEventArgs) e.CancelDialogOpening = True

	If fileDialog Is Nothing Then
		fileDialog = New RadOpenFileDialog()
		fileDialog.Multiselect = True
	End If

	If fileDialog.ShowDialog() = True Then
		For Each file In fileDialog.FileNames
			e.FileNames.Add(file)
		Next file
	End If
End Sub
