Use of a RadInputManager (telerik)

Question

i'm trying to use this control to check a time (HH:MM) a user inserts...

This is what i'm using but not working

            <telerik:RadTextBox ID="txtEstimation" runat="server">
            </telerik:RadTextBox>
            <telerik:RadInputManager ID="RadInputManager1" runat="server">
                <telerik:RegExpTextBoxSetting EmptyMessage="EmptyMessage" ValidationExpression="(([01][0-9])|(2[0-3])):[0-5][0-9]"
                    ErrorMessage="*">
                    <TargetControls>
                        <telerik:TargetInput ControlID="txtEstimation" />
                    </TargetControls>
                </telerik:RegExpTextBoxSetting>
            </telerik:RadInputManager>

I was inspired by this : http://www.telerik.com/help/aspnet-ajax/input-inputmanager-basics.html Thanks in advance for your help

Answer 1

The purpose of the RadInputManager is to convert standard controls to RadControls at runtime. Therefore, you should either have the RadInputManager OR the RadTextBox, but you don't need both.

You can achieve the HH:MM functionality you want with either way you choose. For example:

<telerik:RadTextBox ID="RadTextBox1" runat="server">
</telerik:RadTextBox>

<asp:RegularExpressionValidator
    id="txtValidator"
    runat="server"
    Display="Dynamic"
    ErrorMessage="Please, enter valid time in HH:MM format."
    ValidationExpression="^((?<Hour>[0-9]{1,2})[.:](?=[0-9]{2}))?(?<Minute>[0-9]{1,2})$"
    ControlToValidate="RadTextBox1">
</asp:RegularExpressionValidator>

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Submit" />
