[thchuong]

Hi,

There is a number field which is initialized value to 30, MinValue to 10. After showing, clear the text inside of number field, fire click event of button to retrieve number field value on server side, it returns 10.

Is it a bug?

here is sample code

      <ext:ResourceManager runat="server" ID="rm" ViewStateMode="Enabled" AjaxViewStateMode="Enabled">
      </ext:ResourceManager>
      <ext:Panel runat="server" ID="pn" Width="800" Height="600">
         <TopBar>
            <ext:Toolbar runat="server" ID="toptb">
               <Items>
                  <ext:TabStrip runat="server" ID="tab">

                        <ext:TabStripItem runat="server" ActionItemID="tab1" Title="Tab1">
                        </ext:TabStripItem>

Hi,

Please use .Number instead of .Value.

Well, a number cannot be empty. So, we place .MinValue to .Number if a NumberField is empty.

To check NumberField's text you can use the .RawText property.

[thchuong]

What about property IsEmpty? I already clean the field, that property must true but not.

[Daniil]

I've reproduced. We will investigate.

The issue appears when .MinValue and .Text (.SetValue() as well) are set up for a NumberField.

Here is the code sample to reproduce. Just clear the NumberField and press the button.

Example

<%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
    protected void CheckEmpty(object sender, DirectEventArgs e)
    {
        X.Msg.Alert("Empty?", this.NumberField1.IsEmpty).Show();
    }
</script>
