The properties of numberfield can not be changed from code-behind in the direct event.

[Santon_Lee]

The following is the markup code.

       <ext:Window ID="winCtl" runat="server" Collapsible="false" AutoHeight="true" Icon="ApplicationForm"
            Width="400" Hidden="true" Draggable="true" Resizable="false" Modal="true">
            <Items>
                <ext:FormPanel ID="fpnlCtl" runat="server" ButtonAlign="Right" AutoHeight="true" Header="false" 
                    BodyStyle="background-color:transparent;" Padding="5" LabelAlign="Right" LabelWidth="100">
                    <Items>
                        <ext:Hidden ID="hideActionCtl" runat="server" />
                        <ext:ComboBox ID="ddlCtlPara" runat="server" FieldLabel="Control Parameter" AnchorHorizontal="95%" AllowBlank="false" ForceSelection="true">
                           <Items>
                                <ext:ListItem Text="D" Value="D" />
                                <ext:ListItem Text="H" Value="H" />
                                <ext:ListItem Text="T" Value="T" />
                            </Items>
                            <DirectEvents>
                                <Select OnEvent="ddlCtlPara_SelectedIndexChanged">
                                    <ExtraParams>
                                        <ext:Parameter Name="CtlPara" Value="#{ddlCtlPara}.getValue()" Mode="Raw" />
                                    </ExtraParams>
                                </Select>
                            </DirectEvents>
                        </ext:ComboBox>
                        <ext:NumberField ID="txtMAXParaValue" runat="server" FieldLabel="MAXParaValue" AnchorHorizontal="95%" AllowNegative="false" AllowDecimals="false" />
                        <ext:ComboBox ID="ddlCAType" runat="server" FieldLabel="CA Standard" AnchorHorizontal="95%" />
                    </Items>
                </ext:FormPanel>
            </Items>
        </ext:Window>

The following is the code-behind.

        protected void ddlCtlPara_SelectedIndexChanged(object sender, DirectEventArgs e)
        {
            string strCtlPara = e.ExtraParams["CtlPara"];
            if (strCtlPara== "D")
            {
                txtMAXParaValue.AllowDecimals = false; // Does not work.
                // txtMAXParaValue.Disabled = true; // It works.
                ddlCAType.ForceSelection = true;
                ddlCAType.AllowBlank = false;
                ddlCAType.Disabled = false;                
            }
            else
            {
                if (strCtlPara == "H")
                {
                    txtMAXParaValue.AllowDecimals = true; // Does not work.
                    txtMAXParaValue.DecimalPrecision = 2; // Does not work.
// txtMAXParaValue.Disabled = false; // It works.
                }
                else
                {
                    txtMAXParaValue.AllowDecimals = false; // Does not work.
                    // txtMAXParaValue.Disabled = true; // It works.
                }
                ddlCAType.ForceSelection = false;
                ddlCAType.AllowBlank = true;
                ddlCAType.SelectedItem.Value = "";
                ddlCAType.Disabled = true;
            }
        }

Problem Description:
The property of "AllowDecimals" is not changed after the 'H' is selected. But the property of "Disabled" can be changed correctly. Others work fine.

Can anyone tell me the reason? It's very strange.

Thanks a lot.

I have the same problem here... I'm trying to change the AllowBlank property... but nothing happend.

Maybe it's a Bug?

Thi is my the code with a ComboBox and Numberfield

<ext:ComboBox ID="TdtCodigo" runat="server" Editable="false" AutoWidth="true" StoreID="TdtCodigoStore"  ValueField="Codigo" DisplayField="Nombre" FieldLabel="<%$ Resources:BaseLocalizedText, CamposTablas_TdtCodigo_Mantenimiento%>">
                    <DirectEvents>
                        <Select OnEvent="LengthVal" IsUpload="true">
                            <ExtraParams>
                                <ext:Parameter Name="TipoDato" Value="#{TdtCodigo}.getValue()" Mode="Raw" Encode="true" />
                            </ExtraParams>
                        </Select>

                        <AfterRender OnEvent="LengthVal" IsUpload="true">
                            <ExtraParams>
                                <ext:Parameter Name="TipoDato" Value="#{TdtCodigo}.getValue()" Mode="Raw" Encode="true" />
                            </ExtraParams>
                        </AfterRender>
                    </DirectEvents>

This is the CodeBehind Code:

        bool isNum = double.TryParse(l_strTipoDato, out l_dblTipoDato);
        if (isNum)
            l_strTipoDato = e.ExtraParams["TipoDato"].ToString().Trim();
        else
            l_strTipoDato = "0";
        
        // Example Values
        l_strLongitud = "0";
        char[] l_charSeparator = ".";
        
        if (l_strLongitud == "0")
        {

            // Si no hay una Longitud por Defecto
            Longitud.Clear();
            Longitud.ReadOnly = false;
            Longitud.Cls = "";
            
            Longitud.Regex = "\d{1,2}.\d{1,2}";
            Longitud.RegexText = "Only decimal values";
            l_strMaxValue = "48.48";
            
            if (l_strMaxValue.Split(l_charSeparator).Length == 1)
            {
                Longitud.AllowDecimals = false;
                Longitud.DecimalPrecision = 0;
                Longitud.MaxValue = Convert.ToInt32(l_strMaxValue);
            }
            else
            {
                Longitud.AllowDecimals = true;
                Longitud.DecimalPrecision = Convert.ToInt32( l_strMaxValue.Split(l_charSeparator)[1].Length.ToString() );
                Longitud.MaxValue = Convert.ToDouble( l_strMaxValue.Split(l_charSeparator)[0] );
                Longitud.MaxValue += Convert.ToDouble( l_strMaxValue.Split(l_charSeparator)[1] ) / Math.Pow(10, Longitud.DecimalPrecision);
            }
        }
        else
        {
            // Si hay una longitud por Defecto
            Longitud.SetValue(l_strLongitud);

Maybe is because i'm using UserControl?

I'm trying to with

 X.GetCmp<NumberField>(Longitud.ClientID).AllowDecimals = true;

But... nothing happend!

I think you might need to re-render the Component after setting this property.

After you set your new properties values, call .Render() on the Component. This will force a re-render.

Hope this helps.
