Zero values in textboxes with radinputmanager

[Dennis]

Hi

I have a problem with the Rad inputmanager when using it to generate numeric textboxes.

If I use the inputmanager to create a numeric textbox and default the value to 0 and the wants to save that zero it simply disappears. I need the zero, because an empty textbox has another meaning than a 0.

Is there a setting or something else that I am missing.

Thank you in advance
Dennis

A simple example:

<%

@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="ProductManager.Pages.Products.WebForm1" %>

 

<%

 

@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

 <

html xmlns="http://www.w3.org/1999/xhtml">

 

 

 <

head runat="server">

 </

head>

 

 

 <

body>

 

 

 

<form id="form1" runat="server">

 

 

 

<div>

 

 

 

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

 

 

 <

/telerik:RadScriptManager>

 

 

 

<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>

 

 

 

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

 

 

 

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

 

 

 

<telerik:RadInputManager ID="RadInputManager1" runat="server">

 

 

 

<telerik:NumericTextBoxSetting MinValue="0" Type="Number" AllowRounding="true" DecimalDigits="0">

 

 

 

<TargetControls>

 

 

 

<telerik:TargetInput ControlID="TextBox1" />

 

 

 

</TargetControls>

 

 

 

</telerik:NumericTextBoxSetting>

 

 

 

</telerik:RadInputManager>

 

 

 

</div>

 

 

 

</form>

 

 

 </

body>

 

 

 </

html>
 

 

 

namespace

ProductManager.Pages.Products

{

 

public partial class WebForm1 : System.Web.UI.Page

 

 

 

{

 

 

 

protected void Page_Load(object sender, EventArgs e)

 

 

{

 

if (!IsPostBack)

 

 

 TextBox1.Text = "0

";

 

 

 

}

 

protected void Button1_Click(object sender, EventArgs e)

 

 

 

 

{

Label1.Text = TextBox1.Text;

}

}

}

Hi Dennis,

See the forum link which discusses similar scenario about RadInputManager.

Thanks,
Princy.

Hi Princy

First of all, thanks for your reply :)

For some it might be a solution, but on one of my aspx pages I would need 25 hidden fields, and on another where there are approx. 1000 numerictextboxes in a grid I would need 1000 hidden textboxes :) and therefore I can not see this as a solution.

I have to say, that not being able to enter a zero in a field, must be a bug.

I have made a support ticket, so I hope, that Telerik can helpt with a usable solution.

Hi

I asked Telerik Support and got the following answer, hope it can help others:
Indeed, this issue is present in this version of the control. It is considered as a potential bug, and has been escalated to our developers, and I hope they will address it soon. In the meantime, you can consider using the "EmptyMessage" setting, a possible means to alleviate the issue.

Any word on whether this bug is addressed in the Q1 2009 release?

Hi PJ,

While I cannot commit to a definite timeframe, we will do our best to address the issue soon. Most probably it will be for one of the service packs, subsequent to q1.

All the best,
Yavor
