WinForm UserControls in Internet Explorer
Check out my latest demo that shows a Windows Form UserControl embedded in an ASP.NET Page. It populates the ComboBoxes and DataGrid by calling a WebService that returns DataSets that are bound to the controls. The data is automatically refreshed with the correct child DataSets whenever the selection in one of the ComboBoxes is changed. Note that the Windows Form DataGrid automatically supports Sorting and Scrolling -- all without PostBacks! Note that this does require the client computer to have .NET v1.1 installed locally since it uses Windows Forms.
Please note that you will not be able to see this WinForm control in SharpReader even if you do have .NET v1.1 on your computer.
