Item with null value not editable

Posted 15 years ago by Actipro Software Support - Cleveland, OH, USA

Hi Sascha,

For this type of problem, you would need to send over a small sample project to our support address.

But it sounds like either the PropertyGrid cannot determine the type of the property or there is no TypeConverter available. This depends largely on how you are using the control, which is why the sample project is needed.

Hi Actipro,

your idea with the grid not being able to determine the type of the property is good.
Can I hardcode the the type in xaml / codebehind?

Thanks
Sascha

Hi Sascha,

Again it's hard to say without seeing a sample project, as there are several ways you could be using the PropertyGrid. But typically the class definition or property definition is decorated with the TypeConverterAttribute.

Hi again,

this is the property of the object which I'm using - the datatype should be clear.
To be honest, I don't understand why the propertygrid doesn't recognize it.


/// <summary>
/// There are no comments for Property InternalDesc in the schema.
/// </summary>
[global::System.Data.Objects.DataClasses.EdmScalarPropertyAttribute()]
[global::System.Runtime.Serialization.DataMemberAttribute()]
public string InternalDesc
{
  get
  {
     return this._InternalDesc;
  }
  set
  {
     this.OnInternalDescChanging(value);
     this.ReportPropertyChanging("InternalDesc");
     this._InternalDesc = global::System.Data.Objects.DataClasses.StructuralObject.SetValidValue(value, true);
     this.ReportPropertyChanged("InternalDesc");
     this.OnInternalDescChanged();
  }
}
private string _InternalDesc;
partial void OnInternalDescChanging(string value);
partial void OnInternalDescChanged();

Maybe you can give me a hint now?

Hi Sascha,

Sorry, strings are should be fully handled. Please put together a small sample project that shows the issue and email it over to our support address. Once we have that we can take a look.
