Building Re-Usable ASP.NET User Control and Page Libraries with VS 2008

Greetings,

My intention is to give the user a flexible user control on a master page that does the following:

1. When navigating, a child page will pass the URL (with querystring) and PageTitle to the user control
2. The user control will take those two parameters and insert them as a "breadcrumb" object at first index of a List<breadcrumb> collection

This part works fine through the use of a Repeater with a LinkButton contained in an ItemTemplate. The user sees each of the pages he has been visiting in descending order, the provided benefit is a quick way to re-open records they have recently modified or created.

The part I'm having trouble handling is what happens when the user clicks the LinkButton, which is that the child page adds a new reference to the URL at the beginning of the List<> collection and I cannot seem to control the behavior of removing the LinkButton before it gets re-created. What I've tried doing is:

List<>.RemoveAt(RepeaterCommandEventArgs.Item.ItemIndex);
Repeater1.Controls.Clear();
Repeater1.DataSource = List<>;
Repeater1.DataBind();

While that should work, my CreateBreadCrumb(string url, string title) function gets called by the child page before the UserControl detects the Repeater1_Ite

Although most developers and APIs use the RGB scheme when working with colors, it's not the only available way to represent or select colors. For instance, the standard Windows color-selection dialog box allows you to work with the HSL color scheme in an indirect way. In this article, the author describes several color selection schemes, and uses GDI+ (via the System.Drawing namespace) to create a component that makes it possible for your own applications to provide a simpler, friendlier color chooser. Along the way, you'll get tips to help you use GDI+ in your own apps.

Hello,

      My web application has user control which uses third party controls called Devexpress controls. The user control is a menu  and is part of the Master page. It is placed there because this needs to be available in all the pages. My user controls raises a even on item clicked. Now, My question is that Is there any way to know that the event has occurred in page_load of the current page in which I am in?

I have a dynamic accordion on a page. Set its datasource to an object of paged data source.The user control is in the accordions content template. When i was writing code the properties were showing but after giving the values of databases as

<ContentTemplate>

<uc:UserControl1  runat="server" Property1='<%#DataBinder.Eval(Container.DataItem,"columname1")%>' Property2='<%#DataBinder.Eval(Container.DataItem,"columname2")%>'  ></uc:UserControl1>

</ContentTemplate>

but the values shows null, these properties are shown as textboxes text property by user control.

MoreOver when I checked the values of database Items.So i made a textbox instead of usercontrol here as

<asp:TextBox ID="txtTest" runat="server" Text='<%#DataBinder.Eval(Container.DataItem,"Columname1")%>'></asp:TextBox>

It is showing the correct value. And if i pass the value directly it is also showing correctly like

<uc:UserControl1  runat="server" Property1="XYZ")%>' Property2="ABC")%>'  ></uc:UserControl1>

. where I am wrong
