Set Gridview height to Percentage of Screen Height

I am aware that by setting the dock property, it allows the grid to be same size of the parent (form/user control)
myGridView.Dock = DockStyle.Fill;// This can also be set to left, or right, etc..

Does this help you?

I don't think so - because it can grow/shrink vertically based on the number of rows should the contents be modified dynamically.

In Asp.NET I was able to do the below, does this work for you? It sets as percentage of the of the parent form.

  <asp:GridView  ID="GridView1" runat="server" Width="50%" Height ="50%">
            
        </asp:GridView>

Select allOpen in new window

I tried that.  When the grid had lots of rows it just passed the bottom of the screen.  I'd set it to be 20% of the screen height with verticals scrollbars.

<asp:GridView ID="GridView1" runat="server" DataKeyNames ="xxx"  
        AllowSorting="True" Font-Names="Arial" Font-Size="Small"  
        RowStyle-Wrap="False" BackColor="White" BorderColor="Silver"    
        AutoGenerateColumns="True" onsorting="GridView1_Sorting" Height="20%" Width ="80%">
           
            <RowStyle Wrap="False" />  
             
    </asp:GridView>

Thanks.
