copied!<p>I would suggest moving your from-to dates and submit button to a user control. You can then put that on each report, expose and wire up changed events on your control and expose properties for your from-to date textboxes to pop into your report.</p> <p>In Visual Studio create a user control. If you are unsure how to do this try <a href="http://msdn.microsoft.com/en-us/library/y6wb1a0e.aspx" rel="nofollow">this</a> link.</p> <p>Populate the user control with your text boxes. Something like this:</p> <pre><code><div> <asp:Label ID="FromDateLabel" Text="From:" AssociatedControlID="FromDateTextBox" runat="server" /> <asp:TextBox ID="FromDateTextBox" runat="server" /> <asp:Label ID="ToDateLabel" Text="To:" AssociatedControlID="ToDateTextBox" runat="server" /> <asp:TextBox ID="ToDateTextBox" runat="server" /> <asp:Button ID="UpdateButton" Text="Update" runat="server" onclick="UpdateButton_Click" /> </div> </code></pre> <p>And the code behind for that control. You'll need to expose an event and the two properties, which might look like this:</p> <pre><code>public partial class ReportDateControl : System.Web.UI.UserControl { public event EventHandler UpdateReport; public string FromDate { get { return this.FromDateTextBox.Text; } set { this.FromDateTextBox.Text = value; } } public string ToDate { get { return this.ToDateTextBox.Text; } set { this.ToDateTextBox.Text = value; } } protected void UpdateButton_Click(object sender, EventArgs e) { if (UpdateReport != null) { UpdateReport(this, EventArgs.Empty); } } } </code></pre> <p>In your .aspx page you'll need to register the control, which might go something like this:</p> <pre><code><%@ Register Src="~/Controls/ReportDateControl.ascx" TagPrefix="myapp" TagName="ReportDateControl" %> </code></pre> <p>And then actually put it on the page:</p> <pre><code><myapp:ReportDateControl id="ReportDateControl" runat="server" OnUpdateReport="ReportDateControl_UpdateReport" /> </code></pre> <p>And then wire up the code behind to handle the update events:</p> <pre><code>public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void ReportDateControl_UpdateReport(object sender, EventArgs e) { Controls.ReportDateControl control = (Controls.ReportDateControl)sender; string fromDate = control.FromDate; string toDate = control.ToDate; } } </code></pre> <p>Change the names and formatting where appropriate, but this should give you a good idea.</p>
