Add the ability to resize all columns to fill the available space, same as the AutoSizeColumnsMode property of RadGridView

RadValidationRule allows you to define a rule for a certain control by specifying the PropertyName that has to be validated. However, RadTextBox doesn't offer a property that specifies how many symbols are entered in the editor. This can be checked by the RadTextBox.Text.Length property.  It would be nice to have support for defining nested properties in the validation rules: RadValidationRule.PropertyName ="Text.Length".

Workaround: 

The possible solution that I can suggest is to add a RadValidationRule for empty Text and in addition to this handle the ControlValidation event which occurs before a RadEditorControl is being validated. The RadValidationEventArgs gives very useful information about the tool tip error indication, validation rule, etc. The IsValid argument allows you to override the default result indicating whether the validation fails and change the error message accordingly: 

        public RadForm1()
        {
            InitializeComponent();

            RadValidationRule radValidationRule1 = new RadValidationRule();
            radValidationRule1.AutoToolTip = true;
            radValidationRule1.AddControl(this.radTextBox1);
            radValidationRule1.Operator = Telerik.WinControls.Data.FilterOperator.IsNotLike;
            radValidationRule1.PropertyName = "Text";
            radValidationRule1.ToolTipText = "Text is empty!";
            radValidationRule1.Value = "";

            radValidationProvider1.ValidationRules.Add(radValidationRule1);

            this.radValidationProvider1.ControlValidation += radValidationProvider1_ControlValidation;
        }

        private void radValidationProvider1_ControlValidation(object sender, RadValidationEventArgs e)
        {
            if (e.Control == this.radTextBox1 && this.radTextBox1.Text != string.Empty &&
                this.radTextBox1.TextBoxElement.TextBoxItem.TextLength < 20)
            {
                e.ErrorText = "Text is less than 20 characters !";
                e.IsValid = false;
            }
        }

Add Navigation bar Like the one at the bottom of Outlook 2013 with pop-ups when hovering.

ADD. RadPanorama - add save/load layout functionality so one can save and load the tiles size and position

1) Run the RichTextEditor
2) As you can see there are already some images inserted in the document
3) Right click on any image , and click Edit Image, Image editor dialog box does open up. (as shown in the attached pic EditImageActive1.jpg)
4) click outside the image and right click on the image again, and this time you can see the Edit image option is disabled and this happens consistently. (as shown in the attached pic EditImageInactive.jpg)

One more thing to observe was upon right clicking the image sometimes the Edit image option does show up in the context menu and a different menu appears (as shown in the attached pic NoEditImageOption1)

Steps to reproduce:

1. Open a file dialog

2. In the File name field start typing "k:\ClientFiles"

3. The files are not suggested

Hello,

when the end user paste a path from memory into FileDialog, textbox, and press enter the dialog box not navigate to the folder like Microsoft Dialogbox do.

You are replacing the Microsoft component so it must behavior just like the original.

Best,

jeff

Please refer to the attached tiff file. When you load it in RadImageEditor, its orientation is horizontal and the image looks , not vertical as it is displayed in Windows Photo Viewer:

As a user I want to hide the Grand Totals for specific groups:

The group description now has AutoShowSubTotals property determining whether subtotals will be generated for the description:

this.radPivotGrid1.RowGroupDescriptions.Add(new DateTimeGroupDescription
{
    PropertyName = "OrderDate",
    Step = DateTimeStep.Quarter,
    GroupComparer = new GroupNameComparer(),
    AutoShowSubTotals = false
});
