When TextBox with set MaxLength property has an EmptyMessage longer than MaxLength the form is not submitted in IE11.

Steps to reproduce:
1. Run the following code in IE11:

        <telerik:RadTextBox runat="server" ID="txbRelatedMessageVersion" Width="200px"
            MaxLength="10" EmptyMessage="Message Version" />

        <telerik:RadButton ID="amendBtn" runat="server"
            Text="Submit Page />

2. Click inside RadTextBox

3. Click the button

Result: the empty message is considered as a not valid value and the page is not submitted. Changing the MaxLenght to 15 will allow to submit the page successfully.

The temporal solution is to change the type attribute of the RadNumericTextBox input to "tel". This can be done in the OnLoad client event of the control:


<script>
    function OnLoad(sender, args) {
            sender.get_element().setAttribute("type", "tel");
    }
</script>
<telerik:RadNumericTextBox  RenderMode="Lightweight" runat="server" ID="RadNumericTextBox1" Width="190px" Value="1" EmptyMessage="Enter units count" MinValue="0"  ShowSpinButtons="true" NumberFormat-DecimalDigits="0">
    <ClientEvents OnLoad="OnLoad" />
</telerik:RadNumericTextBox><br />

When the "d" custom format specifier is used to format the Date or DisplayDate of RadDateInput, results are incorrect. Instead of showing only the day of the month, it shows dd/MM/yyyy. This issue affects all Picker controls that are using RadDateInput.

As a workaround, one option would be to define the DateFormat and DisplayDateFormat client-side

        <script type="text/javascript">
            function pageLoad(app, args) {
                var datetimepicker = $find("<%= RadDatePicker1.ClientID %>");
                var date = datetimepicker.get_selectedDate();
                datetimepicker.get_dateInput().set_dateFormat("d");
                datetimepicker.get_dateInput().set_displayDateFormat("d");
                datetimepicker.set_selectedDate(date);
            }
        </script>

another option could be to put a space or a two signle-quotes before or after the format specifier letter in the markup:

e.g.
DateFormat=" d"
DateFormat="d "
DateFormat="''d"
DateFormat="d''"

<telerik:RadDateInput ID="RadDateInput1" runat="server" DateFormat="d " DisplayDateFormat="d " SelectedDate="4/17/2018"></telerik:RadDateInput>

To reproduce the issue:

ASPX:

<telerik:RadTextBox ID="RadTextBox1" runat="server" MaxLength="1700" TextMode="MultiLine" Height="100px" Width="500px">
</telerik:RadTextBox>



Codebehind:

    protected void Page_Load(object sender, EventArgs e)
    {
        RadTextBox1.Text = @"aaaa aaaa aaaa aaaa aaaa aaaa aaaa bbbb aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa bbbb aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa aaaa ";
    }



Load the page, copy the text bbbb and paste it over some aaaa string. The cursor will go to the end and the contents scrolled to the bottom. See the attached video for more information.



The problem has been initially reported in this forum https://www.telerik.com/forums/ie11-radtextbox and recently in ticket #1153271.

When entering a letter in a DigitsOnly Masked textbox, the cursor is moved to the right instead of staying in the same place. 

Demo https://demos.telerik.com/aspnet-ajax/maskedtextbox/overview/defaultcs.aspx

Edge(wrong) - https://www.screencast.com/t/cYRBNxyKNs

Chrome(expected) - https://www.screencast.com/t/OcAxrVKPuYb8

P.S. when pressing 3 keys at the same time, the cursor goes to the end, it might be relevant to this issue

When setting client events in a RadTextBox and using an EmptyMessage, the EmptyMessage will trigger the event on page load.  This is true for a multiple TextMode but others are untested. 

<telerik:RadMaskedTextBox ID="txtCountryDigits" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="50px" Mask="+###" ValidationExpression="+\d{1}.d{1}.d{1}" MaxLength="4" />
<telerik:RadMaskedTextBox ID="txtPhoneNumber" runat="server" SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="116px" Mask = "(###) ###.####" ValidationExpression = "\(\d{3}\) \d{3}\.\d{4}" />
<telerik:RadMaskedTextBox ID="txtExtension" runat="server"  SelectionOnFocus="CaretToBeginning" PromptChar="_" Width="100px" Mask="x##########" MaxLength="11" />

This only affects the Edge browser as far as I can tell.

The Country Digits and Extension only allow one character to be entered when the MaxLength is set equal to the number of characters in the mask.  You can only enter 1 character if you tab into the control.  Click on the control with the cursor does not allow the entry of any digits.   Removing the MaxLength property allows entry of the full input.

When RadText boxes have EnableAriaSupport=True and also have a tooltip set, the JAWS form fields dialog should list the control along with any text that might be in the textbox.
Currently it does not list the text.
see following support ticket for more details:  https://www.telerik.com/account/support-tickets/view-ticket?threadid=1081024

The RadMaskedTextBox DisplayMask does not work properly in case "*" is used in it.

 DateInputSetting in InputManager does not behave as expected.

Use  the code and steps below:

<telerik:RadInputManager ID="RadInputManager1" runat="server">
    <telerik:DateInputSetting BehaviorID="BehaviourFormatHeure" DateFormat="HH:mm:ss" Validation-ValidationGroup="GroupValidation">
        <TargetControls>
            <telerik:TargetInput ControlID="txtHeureDebut"></telerik:TargetInput>
            <telerik:TargetInput ControlID="txtHeureFin"></telerik:TargetInput>
        </TargetControls>
    </telerik:DateInputSetting>
</telerik:RadInputManager>


When  type 5 and quit the input field, it works : 05:00:00 appears
When  type 512 and quit the input field, it works too : 05:12:00 appears
When  type 05:12:27 and quit the input field, it works again : value is unchanged
But when type 051227 and quit the input field, an error is indicated

Date format pattern mapping is incorrect in method InputUtil.MapDateFormatShortCuts:

case "y":
          return dateTimeFormatInfo.MonthDayPattern;
case "Y":
          return dateTimeFormatInfo.MonthDayPattern;

instead of:

case "y":
          return dateTimeFormatInfo.YearMonthPattern;
case "Y":
          return dateTimeFormatInfo.YearMonthPattern;

according to "Standard Date and Time Format Strings" from

RadTimePicker :
           Currently the time picker with time interval 5 minutes shows a large list. Instead of large list display Hours 1 to 12 with AM and PM and Minutes 05 to 55 like the image enclosed. 

The PasswordStrengthChecker doesn't update if you right-click and paste using only the mouse.

To let the applicable keyboard configuration on iOS popup, the HTML5 type attribute on the different inputs should vary. So RadDateInput should have type=date and RadNumericTextBox should have type=number

If multiline textbox has set text that starts with break lines, on every postback one break line disappears form the text.
