display annotation

[Walter]

Hi,

I am searching for a workaround to set the label and description property automatically from the display attribute even if the datafrom is not in the mode AutoGenerateFields=True. I started to create a custom control inherited from DataFormDataField and I was able to read out the correct values by reflection within the OnApplyTemplate event handler:

var dc = this.DataContext;
if(dc != null)
{
    Type t = dc.GetType();
    PropertyInfo pi = t.GetProperty(this.DataMemberBinding.Path.Path);
    var attr = pi.GetCustomAttributes(typeof(DisplayAttribute), true).FirstOrDefault();
    if(attr != null)
    {
        var displayAttr = attr as DisplayAttribute;
        ResourceManager rm = new ResourceManager(displayAttr.ResourceType);        

        this.Label = rm.GetString(displayAttr.Name);      

        this.Description = rm.GetString(displayAttr.Description);

    }
}


Unfortunately the properties are not displayed initially.
Is this in general a good approach for the problem? Where is the correct place (event) to execute the code?

Kind Regards
