Custom Composite Control - How to: <CompositeControl><GridView ...><Columns /></GridView></CompositeControl> with little effort
Let's start with what I'm looking for:
<controls:MyWrapper id="Blah" runat="server">
<content>
<controls:Exporter id="Blah1" runat="server" {This control has an image button and some other controls} />
<controls:GridView {This is a fully functional GridView} />
<controls:CustomFooterDetailer id="Yadda" runat="server" />
</content>
</controls:MyWrapper>
I know I need to create my control, inherits composite control, and create some templates and designers. I have yet to find an example online that explains how to get this particular functionality. I want to restrict the content to only be allowed to use the three controls I showed above, and those controls need to be able to reference the GridView control.

here is the basic start ...you will find more help making your custom appear realistic in design mode.
public
class Wrapper : CompositeControl{
private GridView _grid = new GridView();public GridView Grid{
get { return _grid; }set { _grid = value; }}
protected override void CreateChildControls(){
base.CreateChildControls();this.Controls.Add(_grid);// add as many control as you want....
}
}

I have no problem with the basics, I'm more concerened with how to get my designer to only allow the three controls I specify, without having to regenerate the GridView HTML logic manually.

the control type restriction should be design time or runtime is ok.

I figured out how to get my markup the way I want, now I'm having a problem getting the grid to actually display and retain it's settings. I'm obviously doing something wrong, so here's the latest attempt:
Class GridViewControl works properly on it's own, so there's no problems with that class.
Public Class GridViewManager Inherits CompositeControl Implements INamingContainer
Private WithEvents _GridView As GridViewControl
Protected Overrides Sub CreateChildControls() MyBase.CreateChildControls()If _GridView Is Nothing Then _GridView = New GridViewControl Me.Controls.Add(_GridView) End SubProtected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
_GridView =
Me.Controls.Item(0)writer.Write(
"<table cellpadding=""0"" cellspacing=""0"" style=""width:" & _GridView.Width.ToString & ";"">")writer.Write("<tr><td align=""Left"">")_GridView.RenderControl(writer)
writer.Write(
"</td></tr>")writer.Write(
"</table>") End Sub<PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(GetType(GridViewControl))> _ Public Property GridView() As GridViewControl Get Select Case True Case Me.Controls.Count = 0, Me.Controls.Item(0).GetType.Name <> "GridViewControl" Return Nothing Case Else_GridView = Me.Controls.Item(0) Return Me.Controls.Item(0) End Select End GetSet(ByVal value As GridViewControl) Select Case TrueCase Me.Controls.Count = 0 Me.Controls.Add(value) Case Me.Controls.Item(0).GetType.Name <> "GridViewControl"Me.Controls.AddAt(0, value) Case ElseMe.Controls.RemoveAt(0) Me.Controls.AddAt(0, value) End Select
_GridView = value
End Set End PropertyEnd Class
I get a value control on property set, but on render, the control is a blank instantiation.

Well, I figured it out. The following is the shell of what it takes to get the desired functional markup I intially posted. I'm still working on this, but I'm guessing that I don't even need the CreateChildControl override with the way I'm managing the child controls. Hope this is helpful to someone, since I wasn't able to find anything online that explained how to do this.Public Class GridViewManager Inherits CompositeControl Implements INamingContainer
Private WithEvents _GridView As GridViewControl
Protected Overrides Sub CreateChildControls() MyBase.CreateChildControls() If GridView IsNot Nothing Then Me.Controls.Add(GridView) End SubProtected Overrides Sub Render(ByVal writer As System.Web.UI.HtmlTextWriter)
_GridView =
Me.Controls.Item(0)_GridView.RenderControl(writer)
End Sub<PersistenceMode(PersistenceMode.InnerProperty), TemplateContainer(GetType(GridViewControl))> _ Public Property GridView() As GridViewControl Get Select Case True Case Me.Controls.Count = 0, Me.Controls.Item(0).GetType.Name <> "GridViewControl" Return Nothing Case Else _GridView = Me.Controls.Item(0) Return Me.Controls.Item(0) End Select End Get Set(ByVal value As GridViewControl) If value.ID IsNot Nothing Then Select Case True Case Me.Controls.Count = 0 Me.Controls.Add(value) Case Me.Controls.Item(0).GetType.Name <> "GridViewControl" Me.Controls.AddAt(0, value) Case Else Me.Controls.RemoveAt(0) Me.Controls.AddAt(0, value) End Select End If_GridView = value
End Set End PropertyPrivate Sub GridViewManager_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init If Me.Controls.Count > 0 Then If Me.Controls.Item(0).GetType.Name = "GridViewControl" Then _GridView = Me.Controls.Item(0) End If End Sub End Class
