在ASP中动态添加控件时更改母版页中布局的高度

Question

![enter image description here][1]How can I change the height of the layout of the my page when the user adds new controllers. I would like to enhance the height of my page when the user adds a new control.

I am using in master page

<div class="main">
     <asp:ContentPlaceHolder ID="MainContent" runat="server"/>
</div>

and in my css

.main
{
    padding: 0px 12px;
    margin: 12px 8px 8px 8px;
    height: auto; 
}

One more question, can I achieve that programmatically in aspx.cs file ?

Any advice would be appreciated. Thank you.

Answer 1

As long as your asp:Content has elements's in that have content in or a set height it should add to the height of the page

example

<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<div>

</div>
</asp:Content>

Also need to check for CSS styles that are altering the height of div's as this will effect any content you place in there
