gridview changes height

Question

title says it all, I have a gridview, and the second page does not fill the 10 so it changes height, I need it to stay the same no matter what. I will change to whatever I need to get this done, Ive tried everything I can find online like taking out the height attribute and moving it to css, nothing has worked. I need the gridview to stay the same way , whether that be insert blank rows to make up the space or whatever. 


the CSS i tried is:

.RowStyle {

 height: 50px;

 }

 .AlternateRowStyle {

  height: 50px;

 }


and the HTML I am using currently is:

<asp:Panel runat="Server" ID="AnonymousMessagePanel">

         <br />

        <asp:GridView ID="CompletedProjectsGrid" runat="server" AllowSorting="True" AutoGenerateColumns="False" DataSourceID="ProjectsClosedList" 

            EnableViewState="False" DataKeyNames="ProjectID" CssClass="mGrid" PagerStyle-CssClass="pgr"  RowStyle-CssClass="RowStyle" 

            AlternatingRowStyle-CssClass="alt" AllowPaging="true" PageSize="10">

            <Columns>

                <asp:BoundField DataField="ProjectID" HeaderText="ProjectID" HeaderStyle-ForeColor="White" SortExpression="ProjectID" ReadOnly="True" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="ProjectName" HeaderText="ProjectName" HeaderStyle-ForeColor="White" SortExpression="ProjectName" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="TesterName" HeaderText="TesterName" HeaderStyle-ForeColor="White" SortExpression="TesterName" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="ProjectDescription" HeaderText="ProjectDescription" HeaderStyle-ForeColor="White" SortExpression="ProjectDescription" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="Platform" HeaderText="Platform" HeaderStyle-ForeColor="White" SortExpression="Platform" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="DueDate" HeaderText="DueDate" HeaderStyle-ForeColor="White" SortExpression="DueDate" dataformatstring="{0:M/dd/yyyy}" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="DateAssigned" HeaderText="DateAssigned" HeaderStyle-ForeColor="White" SortExpression="DateAssigned" dataformatstring="{0:M/dd/yyyy}" ItemStyle-Width="11%"/>

                <asp:BoundField DataField="DocumentName" HeaderText="DocumentName" HeaderStyle-ForeColor="White" SortExpression="DocumentName" ItemStyle-Width="11%"/>

            </Columns>

            </asp:GridView>

        <asp:SqlDataSource ID="ProjectsClosedList" runat="server" 

                   ConnectionString="<%$ ConnectionStrings:ProjectsAndTasksTestConnectionString %>" 

                   SelectCommand="SELECT [ProjectID], [ProjectName], [TesterName], [ProjectDescription], [Platform], [DueDate], [DateAssigned], [DocumentName] FROM [Projects] WHERE ([DateCompleted] IS NULL)">

               </asp:SqlDataSource>

    </asp:Panel>
