Private Sub Button1_Click() Handles Button1.Click
    Dim msgString As String 
    Dim intFull As Integer 
    Dim intPartial As Integer 
    ' Get the count without including partially displayed items.
    intFull = DataRepeater1.DisplayedItemCount(False)
    ' Get the count, including partially displayed items.
    intPartial = DataRepeater1.DisplayedItemCount(True)
    ' Create the message string.
    msgString = CStr(intFull)
    msgString &= " items are fully visible and " 
    ' Subtract the full count from the partial count.
    msgString &= CStr(intPartial - intFull)
    msgString &= " items are partially visible."
    MsgBox(msgString)
End Sub

private void button1_Click(System.Object sender, System.EventArgs e)
{
    string msgString;
    int intFull;
    int intPartial;
    string stringFull;
    string stringPartial;
    // Get the count without including partially displayed items.
    intFull = dataRepeater1.get_DisplayedItemCount(false);
    // Get the count, including partially displayed items.
    intPartial = dataRepeater1.get_DisplayedItemCount(true);
    // Create the message string.
    stringFull = intFull.ToString();
    msgString = stringFull;
    msgString = msgString + " items are fully visible and ";
    // Subtract the full count from the partial count.
    intPartial = intPartial - intFull;
    stringPartial = intPartial.ToString();
    msgString = msgString + stringPartial;
    msgString = msgString + " items are partially visible.";
    MessageBox.Show(msgString);
