[CLOSED] Issues related to custom control

[AnulekhaK]

HI Daniil,

I have a custom control extending the formpanel. I am having two issues.

1. I want to control the "allowblank" properties for the controls within the custom control by exposing a property (IsMandatory in below code). How to do this? The same behaviour is required for visible and readonly properties.

2. When i add the same control twice, only one control is displayed. Please advise.

Custom Control
 public class NxtDecimalNumberRange : NxtFormPanel
    {
        ResourcePlaceHolder decimalrangeholder = new ResourcePlaceHolder();
        NxtNumberField FromNumber = new NxtNumberField();
        NxtNumberField ToNumber = new NxtNumberField();

        public override string XType { get { return "NxtDecimalNumberRange"; } }

      
        public NxtDecimalNumberRange()
        {

            FromNumber.ID = "FromNumber";
            FromNumber.Vtype = "decimalnumberrange";
            FromNumber.Note = "From (number)";
            FromNumber.Width = 100;
            //FromNumber.AllowBlank = false;
            FromNumber.AllowDecimals = true;
            FromNumber.AllowNegative = false;
            FromNumber.DecimalPrecision = 4;
            FromNumber.DecimalSeparator = ",";
            //FromNumber.IndicatorIcon = Icon.BulletRed;

            ConfigItem FromNumberConfig = new ConfigItem();
            FromNumberConfig.Name = "endNumberField";
            FromNumberConfig.Value = "#{ToNumber}";
            FromNumberConfig.Mode = ParameterMode.Value;
            FromNumber.CustomConfig.Add(FromNumberConfig);

            ToNumber.ID = "ToNumber";
            ToNumber.Vtype = "decimalnumberrange";
            ToNumber.Note = "To (number)";
            ToNumber.Width = 100;
            // ToNumber.AllowBlank = false;
            ToNumber.AllowDecimals = true;
            ToNumber.AllowNegative = false;
            ToNumber.DecimalPrecision = 4;
            ToNumber.DecimalSeparator = ",";
            //ToNumber.IndicatorIcon = Icon.BulletRed;

            ConfigItem ToNumberConfig = new ConfigItem();
            ToNumberConfig.Name = "startNumberField";
            ToNumberConfig.Value = "#{FromNumber}";
            ToNumberConfig.Mode = ParameterMode.Value;
            ToNumber.CustomConfig.Add(ToNumberConfig);

            Parameter margin = new Parameter();
            margin.Name = "margins";
            margin.Value = "0 7 0 0";
            margin.Mode = ParameterMode.Value;
            this.Defaults.Add(margin);
            this.Layout = "HBoxLayout";
            HBoxLayoutConfig config = new HBoxLayoutConfig();
            config.Pack = BoxPack.Start;
            this.LayoutConfig.Add(config);
            this.Items.Add(FromNumber);
            this.Items.Add(ToNumber);
        }
            

        protected override void OnInit(EventArgs e)
        {
            base.OnInit(e);
            this.FieldLabel = LocalizationManager.GetCultureSpecificValue(this.GetType().Name + "." + this.GetType().Name);
            
        }

        public bool IsVisible
        {
            get { return (ToNumber.Visible && FromNumber.Visible); }
            set
            {
                ToNumber.Visible = value;
                FromNumber.Visible = value;
            }
        }

        public bool IsMandatory
        {
            get { return (this.ToNumber.AllowBlank && this.FromNumber.AllowBlank); }
            set
            {
                if (value)
                { this.ToNumber.IndicatorIcon = Icon.BulletRed; }

                this.ToNumber.AllowBlank = !value;
                this.FromNumber.AllowBlank = !value;
            }
        }

        public bool IsReadOnly
        {
            get { return (ToNumber.Disabled && FromNumber.Disabled); }
            set
            {
                ToNumber.Disabled = value;
                FromNumber.Disabled = value;
            }
        }

C# code
NxtDecimalNumberRange decimalnumberrange = new NxtDecimalNumberRange();
                            decimalnumberrange.IsMandatory = true;
                            decimalnumberrange.IsVisible = true;
                            decimalnumberrange.IsReadOnly = true;
                            script +=  decimalnumberrange.ToScript(RenderMode.AddTo, containerPanel);

                            NxtDecimalNumberRange decimalnumberrange1 = new NxtDecimalNumberRange();
                            decimalnumberrange.IsMandatory = true;
                            decimalnumberrange.IsVisible = true;
                            decimalnumberrange.IsReadOnly = true;
                            script +=  decimalnumberrange1.ToScript(RenderMode.AddTo, containerPanel);

Hi,

1. I want to control the "allowblank" properties for the controls within the custom control by exposing a property (IsMandatory in below code). How to do this? The same behaviour is required for visible and readonly properties.

Your implementation of the IsMandatory property appears to be correct. At least, it works in the example below.

Could you provide more details what is going wrong on your side?

Example

<%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<script runat="server">
    class MyFormPanel : FormPanel
    {
        TextField TextField1 = new TextField();
        
        public MyFormPanel()
        {
            this.Items.Add(this.TextField1);   
        }

        public bool IsMandatory
        {
            get 
            {
                return !this.TextField1.AllowBlank;  
            }
            set
            {
                this.TextField1.AllowBlank = !value;
            }
        }
    }

    protected void Page_Load(object sender, EventArgs e)
    {
        MyFormPanel mfp = new MyFormPanel();
        mfp.IsMandatory = true;

        this.Form.Controls.Add(mfp);
    }
</script>

2. When i add the same control twice, only one control is displayed. Please advise.

Please keep one issue per one thread. So, please start a new froum thread.
