All,

Maybe more information will be helpful. I have created a custom control subclassing mmDropDownList including a mmBusinessObject as a child control. The CreateChildControl method is:

protected override void CreateChildControls()
{
Controls.Clear();

oCounties = new Counties();

this.BindingSource="Counties";
this.BindingSourceDisplayMember = "County";
this.BindingSourceValueMember = "CountyId";
}

When I drop this control on a form, the BindingSource, BindingSourceDisplayMember, and the BindingSourceValueMember are all blank. Do I need to run the this.EnsureControls() method is run before Rendering the control?

TIA

Rex
