The default repeater control does not come with a case for when the datasource is null or empty. This presented somewhat of a problem for me, so I figured I would post my solution so that others could make this change as well. I have uploaded the dll file, you can download it at the end of this post.

[ToolboxData("<{0}:CustomRepeater runat=server>")]
public class CustomRepeater : Repeater
{
	    #region Public Properties

	    [Category("Data")]
	    [DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
	    [PersistenceMode(PersistenceMode.InnerProperty)]

	    public ITemplate EmptyTemplate
	    {
	        get;
	        set;    
	    }
	
	    #endregion
	
		    #region Protected Overrides Methods
		
		    protected override void CreateChildControls()
		    {
		        base.CreateChildControls();
		        HandleEmptyData();
		    }
		    protected override void  OnDataBinding(EventArgs e)
		    {
		        base.OnDataBinding(e);
		        HandleEmptyData();
		    }
		
		    #endregion

		    #region Private Methods

		    private void HandleEmptyData()
		    {
		        if (this.Items.Count <= 0 && EmptyTemplate != null)
		        {
		           this.Controls.Clear();
		            HeaderTemplate.InstantiateIn(this);
		            EmptyTemplate.InstantiateIn(this);
		            FooterTemplate.InstantiateIn(this);
		        }
		    }
	
		    #endregion
		}

After compiling this into a bin it can be implemented in the following way:

	<%@ Register TagPrefix="MC" Namespace="MyControls" Assembly="MyControls" %>
