Hi all,

I am facing problem when creaing custom String property which MaxLength should only be 10. Even i run the project and Adding a property to template i could enter more than 10 characters. What may be the problem? Please look into the below code and tell me whether it is correct way or not. I have added the CustomControl in Models Folder.

TextPropertyCustom.cs

using System;
using System.Collections.Generic;
using System.Text;
using EPiServer;
using EPiServer.Core;
using EPiServer.DataAbstraction;
using EPiServer.PlugIn;
using EPiServer.Web.PropertyControls;

namespace MyDemo1.Models
{
    /// <summary>
    /// Custom PropertyData implementation
    /// </summary>
    [Serializable]
    [PropertyDefinitionTypePlugIn]
    public class TextPropertyCustom : EPiServer.Core.PropertyString
    {
        public override int MaxLength
        {
            get
            {
                return base.MaxLength;
            }
            set
            {
                base.MaxLength = 10;
            }
        }

        public override IPropertyControl CreatePropertyControl()
        {
            return new TextPropertyCustomControl();
        }

    }
}

TextPropertyCustomControl.cs

using System;
using System.Collections.Generic;
using System.Text;
using EPiServer;
using EPiServer.Core;
using EPiServer.DataAbstraction;
using EPiServer.Web.PropertyControls;
using EPiServer.Web.WebControls;

namespace MyDemo1.Models
{
    /// <summary>
    /// PropertyControl implementation used for rendering TextPropertyCustom data.
    /// </summary>
    public class TextPropertyCustomControl : EPiServer.Web.PropertyControls.PropertyStringControl
    {
        public TextPropertyCustom TextPropertyCustom
        {
            get
            {
                return PropertyData as TextPropertyCustom;
            }
        }
    }
}

And one more query, Where i can exactly create this custom controls? Whether in Models folder or Models - Pages Folder?

You do not need a custom property for this, just do like this:

[Display(
        Name = "StringLenghAttribute",
        Description = "StringLenghAttribute.",
        GroupName = "Validation tests",
        Order = 101)]
[StringLength(10)]
public virtual string StringLenghAttribute { get; set; }

David explains the validation attributes here:
