There's a section about this already in the .NET Framework SDK. Read Generating and Compiling Source Code Dynamically in Multiple Languages[^]. It would've also been better if you tried searching CodeProject first. There's thousands of articles about many subjects, and researching is part of "Research and Development". The following search yields many decent articles: http://www.codeproject.com/info/search.asp?cats=3&cats=5&searchkw=CodeDom[^] Microsoft MVP, Visual C# My Articles

Hi there. On first glance, I would check to make sure that FindControl("txtbox"+i.ToString()+j.ToString()) was returning a valid control and not null... I would guess it is returning null. Is the "txtbox__" name correct? Are the textboxes deeper in some Controls collection of a specific control? If the latter is true, you may want to use the FindControl method of the container control instead of that of the Page.

You could save manually adding each textbox to the array by using FindControl: for(int i=0; i<6; i++) { txtArray.Add(FindControl("txt"+i)); } Hope this helps Paul
