Question

I have a DropdownList ASP control, which is populating by DataSet.

I am using .net 3.5, c#.

To control the height of DropDownList, i am using the following code and it is working.

<asp:DropDownList size="1"
            onMouseOver="this.size=10;"             
            onMouseOut="this.size=1;"
            style="display:none; position:absolute; width:150px;" 
            runat="server"></asp:DropDownList>

But it is flickering when clicking on it, means first it shows all values and again resized for 10, provided length of the control.

Thanks

Yes, I got the correct answer.
Following code is working properly for me.

<asp:DropDownList ID="ddl" width="100px" onclick="this.size=1;" onMouseOver="this.size=10;" onMouseOut="this.size=1;" style="position:absolute;" runat="server"></asp:DropDownList>

Using position:absolute; and this.size, i am able to manage the # of items (10 visible).
