Hi,
I want to pass a value to a user control on my aspx page , I have done this when i have data in a repeater, but dont know how to pass the data when I dont have a repeater. My control is just in a div

I want to pass the value of the HatID, i have a method that returns the hatid which is GetRandomImageURL()

Thanks
<div>
<HatPhotoControl:HatPic HatID='<%#DataBinder.Eval(Container.DataItem,"HatID")%>' runat="server" />
</div>

i beleive  you just have to add a property to the code behind of the user control:
private string hatID="";
public string HatID
{
  get
  {
     return this.hatID;
  }
  set
  {
     this.hatID = value;
  }

}

Use <%=[Your Value]%> if you binding to a property on the page. Also You can pass a value in you user control's onInit or OnLoad events ;) by assigning the value in code.

Oh I think I see what you're saying.

Give the UserControl an ID....
<HatPhotoControl:HatPic ID="MyHatPic" HatID='<%#DataBinder.Eval(Container.DataItem,"HatID")%>' runat="server" />

Then assign the property in the code behind of the aspx page...
MyHatPic.HatID = "my value";

Yes but do not assigne  HatID='<%#DataBinder.Eval(Container.DataItem,"HatID")%>'  since you control is not part of databound container such as repeater ;)

thanks vb, i meant to take that out.  So the correct answer is:
Give the UserControl an ID....
<HatPhotoControl:HatPic ID="MyHatPic" runat="server" />

Then assign the property in the code behind of the aspx page...
MyHatPic.HatID = "my value";
