I have created a user control, and, I would like to use it in two different forms within my website, however, some "parameters", might be different including:

* The underlying SQL DataSource
* Behavior might be different (gut feeling)

XML

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Envelope.ascx.cs" Inherits="Envelope" %>
<asp:FormView ID="MessageForm" runat="server" DataSourceID="SqlDataSource1"
            AllowPaging="True"
            OnItemDeleted = "ArticleEnvelope_Deleted"
            OnItemInserted = "ArticleEnvelope_Inserted"
            OnItemUpdated = "ArticleEnvelope_Updated">
        <HeaderTemplate>
        </HeaderTemplate>
        <EditItemTemplate>
            Timestamp:
            <asp:TextBox ID="TimestampTextBox" runat="server"
                Text='<%# Bind("Timestamp") %>' />
            <br />
            Subject:
            <asp:TextBox ID="SubjectTextBox" runat="server" Text='<%# Bind("Subject") %>' />
            <br />
            EntryText:

So, how is it possible to dynamically assign the SQL DataSource of a User Control, from different forms (aspx)?

Here is how you should be able to do it:

1. Remove the SqlDataSource from the User control, and, keep only the FormView. For example:

XML

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="UcDetails.ascx.cs" Inherits="UcDetails" %>
<asp:FormView ID="FormView1" runat="server">
</asp:FormView>

2. Create a SqlDataSource parameter inside the User control's code behind and assign FormView's DataSourceID in the Page_Load(). For example:

C#

public SqlDataSource DataSource
{
    get;
    set;
}
protected void Page_Load(object sender, EventArgs e)
{
    FormView1.DataSourceID = DataSource.ID;
}

3. Put the SqlDataSource in the Aspx pages. For example:

XML

<body>
    <form id="form1" runat="server">
    <uc1:UcDetails ID="UcDetails1" runat="server" />
    <asp:SqlDataSource ID="SqlDataSource1" runat="server"></asp:SqlDataSource>
    </form>
</body

>

4. Set the DataSource of the FormView into the Page_Load() of aspx pages. For example:

C#

protected void Page_Load(object sender, EventArgs e)
{
        UcDetails1.DataSource = SqlDataSource1;
}

I think you should get the basic idea and can implement your functionality.
