<telerik:RadInputManager ID="radInputManager1" runat="server"> <telerik:NumericTextBoxSetting BehaviorID="NumericBehavior" EmptyMessage="######" InitializeOnClient="false" Type="Number" DecimalDigits="0" GroupSeparator="" Validation-IsRequired="false"> </telerik:NumericTextBoxSetting></telerik:RadInputManager>I apply the setting to a textbox in code-behind. When I don't enter a value in the textbox, the Text property of the textbox returns the inputmanager setting's EmptyMessage, "######". I would expect the Text property to return what was input in the control, in this case an empty string, not the emptymessage. Is there a way to accomplish this?

Hi Waylon,
The observed behavior should not occur. I suggest you to check for Javascript errors.

So it appears that I get the correct value in the page load event, but not in the button click event. In my application, the textbox is inside the form template of a radgrid and I need to get the value on insert/update, so I really need access outside of the page load event.
<%@ Page Language="C#" %><%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %> <script runat="server"> protected void Page_Load(object sender, EventArgs e) { radInputManager1.GetSettingByBehaviorID("NumericBehavior").TargetControls.Add(new TargetInput("TextBox1", true)); } protected void Button1_Click(object sender, EventArgs e) { Label1.Text = TextBox1.Text; } </script> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" <html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server"><meta http-equiv="content-type" content="text/html;charset=utf-8" /><title>RadControls</title></head><body><form id="form1" runat="server"><asp:ScriptManager ID="ScriptManager1" runat="server" /> <telerik:RadInputManager ID="radInputManager1" runat="server"> <telerik:NumericTextBoxSetting BehaviorID="NumericBehavior" EmptyMessage="######" InitializeOnClient="false" Type="Number" DecimalDigits="0" GroupSeparator="" Validation-IsRequired="false"> </telerik:NumericTextBoxSetting></telerik:RadInputManager> <p>Leave the textbox with no value and submit</p> <asp:TextBox ID="TextBox1" runat="server" /> <br /><br /> <asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" /> <br /><br /> textbox value: [<asp:Label ID="Label1" runat="server" />] </form></body></html>0

Hi Waylon Campbell,
I see. This is not an expected behavior indeed, and we will have to fix it. In the meantime, you can remove the empty message or retrieve the "real" submitted value like this:
Request.Form[TextBox1.ClientID]
I have updated your Telerik points for bringing the issue to our attention. Thank you.
