In Master Data Services (MDS), when using the Master Data Manager Web User Interface (“UI”), you will notice the “Leaf member attributes” box on the “Edit Entity” screen is too small.  It only fits four rows.  This can be very annoying as you will need to use the scroll bars on just about every entity you are looking at.  But there is an easy fix.

To increase the size of this box: On the server where MDS is installed, edit the file domain.aspx (located in C:\Program Files\Microsoft SQL Server\110\Master Data Services\WebApplication\Admin) and add the Height tag:

<asp:ListBox ID=”lstFreeFormAttributes” CssClass=”LabelText” runat=”server” Visible=”False”
Width=”400px” AutoPostBack=”True” OnSelectedIndexChanged=”lstFreeFormAttributes_SelectedIndexChanged” meta:resourcekey=”lstFreeFormAttributesResource1″>
ListBox>

to

<asp:ListBox ID=”lstFreeFormAttributes” CssClass=”LabelText” runat=”server” Visible=”False” Height=”250px”
Width=”400px” AutoPostBack=”True” OnSelectedIndexChanged=”lstFreeFormAttributes_SelectedIndexChanged” meta:resourcekey=”lstFreeFormAttributesResource1″>
</asp:ListBox>

This will make it fit 18 rows.
