Panel Curve Container - An ASP.NET Custom Control Nugget

An ASP.NET custom panel control which is curved on the corners, could be minimized/maximized, displayed as a nugget, and can work as a container for anything.


I wanted to have a control which could work as a container and be used similar to System.Web.UI.WebControls.Panel <ASP:PANEL>, which is curved at corners and at the same time has its own custom header text.


I searched the internet a lot to find control similar to the Panel control but never got any help. So I decided to make one on my own. One way to do this was to create a user control which forms the curve and ask the developer to pass the values to this control, which was making the entire process too complex (creating too many user controls was a tedious job and would be difficult to manage), at the same I didn't want to place every code of mine inside a user control just for the sake of forming boundaries. Finally, one of the MSDN examples talked about such an implementation, but then it also had a flaw, it would throw an error if the control is used inside a user control or a DataGrid because the IDs are prefixed to the child control in this case. Then, I created my own control and tested it successfully inside a user control, a DataGrid, a nested DataGrid, and in many other ways, and it always worked.


The following features are available for this control:

  • Curved tab header.
  • Minimize icon to minimize the tab.
  • Print icon to print the selected nugget.
  • You can customize the header text displayed in the header.
  • You can change the background color of the top tab or the bottom body.
  • You can use a user control, custom control or any web control inside the container and still you can access those controls directly in your code-behind.

    In the code-behind:

    protected TextBox txt;

    In the aspx:

    <Tittle:PanelCurveControl ...>
    <asp:textbox id=txt ... /> 
  • This control will maintain its minimize/maximize state during postback.
  • This control can be used inside a DataGrid or a User Control (where the IDs of the parent control are prefixed to that of the child control), without any issue.

How to use it

If you have ever used <asp:panel>, then you can use this custom control as well:

<Tittle:PanelCurveControl ID=
 "Panelcurvecontrol1" runat="server" Title="My first Panel" >
       <asp:textbox id=txt runat=server />            

The above would be rendered as:


  • Expandable: Makes the control expandable on demand. Default: true.
  • RenderInBox: Renders the contents in the box. Default false (used only if Expandable is false). Making Expandable true makes the tab disappear, but if Expandable is false:
    • RenderInBox being "true" shows the border of the container.
    • RenderInBox being "false" shows no borders.
  • Closed: Whether the contents of the expandable panel must be visible.
  • Title: The text displayed as the caption of the expandable panel.
  • Margin: Margin to use if the panel is expandable.
  • HasMinimize: Whether to show minimize icon on screen or not.
  • HasPrint: Whether to show Print icon on screen or not.
  • DefaultMinimize: Render it minimized by default or not.
  • BodyBackColor: Content back color.
  • TabBackColor: Top tab back color.
  • HeaderTextColor: Top header text color.

Some Technical Details

I've inherited this control from ASP:Panel so that it can be used in the same manner as Panel. I have not deliberately inherited it from INamingContainer, and the reason behind this is that I didn't want it to prefix the parent ID before every child control ID (it gives a problem if the control is used inside a grid or a user control). A hidden field is used which retains its minimize/maximize state during postbacks. I fixed a hidden field ID so that it maintains the state in a normal page and inside any control.

if ( this.UniqueID.IndexOf(":") >=0 )
    hdn.ID = this.ID + "_hdnMinimizeState"; 
    //Within some user control or grid 
    //E.g. client id will be in this case 
    hdn.ID = this.UniqueID + "_hdnMinimizeState"; 
    //Straight on aspx page, 
    //E.g. client id will be in this case
