Hi smi-mark,

You are absolutely right. The buddy class will be more usefull if one is trying to override the verifier of one specific entity's property. In the situation where you want to override a verifier "globally", your approach is better suited.

I guess I was so excited to share this new feature that ended up neglecting this detail.

Thanks for bringing it up.

If he is trying to replace every string verifier in the edmx, would the template not be the easiest approach? if it was only a few properties then yes the buddy approach would be more practical.

Hi Jignesh and smi-mark,

Now you can also use a "buddy" class and create a verifier to override the verifier in the generated code. This way you don't need to customize the designer template.

The "buddy" class is a new feature available in DevForce 6.0.8 and you can find more information about it in our DevForce resource Center.

Try this, go into your Model.IB.Designer.cs file and replace it with this

<#@ template  language="C#" debug="true" hostSpecific="true" #>
<#@ output extension=".ReadMe" #>
<#@ Assembly Name="System.Core.dll" #>
<#@ Assembly Name="IdeaBlade.VisualStudio.DTE.dll" #>
<#@ Assembly Name="IdeaBlade.VisualStudio.OM.CodeGenerator.dll" #>
<#@ Assembly Name="IdeaBlade.EntityModel.Edm.Metadata.dll" #>
<#@ import namespace="System" #>
<#@ import namespace="System.Reflection" #>
<#@ import namespace="IdeaBlade.VisualStudio.DTE" #>
<#@ import namespace="IdeaBlade.VisualStudio.OM.CodeGenerator" #>
<#@ import namespace="IdeaBlade.EntityModel.Edm.Metadata" #>
<#
	// Source for this file located at: C:\Users\Mark\AppData\Local\Microsoft\VisualStudio\10.0\Extensions\IdeaBlade, Inc\IdeaBlade OM Designer Extension\6.0.8.1\DomainModelTemplate.tt
	// YourEdmxName.edmx  <--- This is needed so that "Transform Related Text Templates On Save" works correctly.
	var template = new NewTemplate(this);
	template.Generate();
#>
<#+ 
public class NewTemplate : DomainModelTemplate
    {
        public NewTemplate(Microsoft.VisualStudio.TextTemplating.TextTransformation textTransformation) : base(textTransformation)
        {
        }
 
        protected override void WriteAttribute(string attribute, bool isInCSharpFormat = true)
        {
            var newAttribute = attribute.Replace("IbVal.StringLengthVerifier", "MyStringLengthVerifier");
            base.WriteAttribute(newAttribute, isInCSharpFormat);
        }
 
    }
#>

It is very important that you replace "YourEdmxName" with the proper name

Hi ,

By default , Ideablade uses StringLengthVerifier in autogenerated code for entity model like below ,

///

Gets or sets the Address2.

    [Bindable(true, BindingDirection.TwoWay)]
    [Editable(true)]
    [Display(Name="Address2", AutoGenerateField=true)]
    [IbVal.StringLengthVerifier(MaxValue=50, IsRequired=true, ErrorMessageResourceName="Doctor_Address2")]
    [DataMember]
    public string Address2 {
      get { return PropertyMetadata.Address2.GetValue(this); }
      set { PropertyMetadata.Address2.SetValue(this, value); }
    }
    #endregion Address2 property

Is there a way to supply myown MyStringLengthVerifierso that it generates the code like this.

///

Gets or sets the Address2.

    [Bindable(true, BindingDirection.TwoWay)]
    [Editable(true)]
    [Display(Name="Address2", AutoGenerateField=true)]
    [MyStringLengthVerifier(MaxValue=50, IsRequired=true, ErrorMessageResourceName="Doctor_Address2")]
    [DataMember]
    public string Address2 {
      get { return PropertyMetadata.Address2.GetValue(this); }
      set { PropertyMetadata.Address2.SetValue(this, value); }
    }
    #endregion Address2 property

We wouldlike to handle IsRequired property differently. Currently if string column in database tableis set to NOT NULL , Ideablade turns IsRequired = true and doesn't allowto assign empty string like '’ which isvalid value for NOT NULL fields in database.

So in abovecase Address2 can be NOT NULL in database table and can still accept emptystring '' without triggering validation.
