I am working on a webpage in ASP.Net/C# that uses absolute positioning for a textbox, for several in fact. It was working just fine, until I added some more text boxes. That is, the existing text boxes still positioned correctly, but the new ones did not, despite the fact that I created new styles in the CSS for them just like the others...
I tried using the Microsoft ReportingControls but found them overly cumbersome, with too little documentation. I'd like a simple control that would convert a GridView control into a PDF document. I've started looking into PDFSHarp and am running into dead ends with documentation. Same thing with iTextSharp. I'm willing to dig into th...

Although most people say that it is easy to use, I find it rather complicated, as we must copy the whole HTML code inside the 'Render' function. Is ther...

I make business web apps whi...
On an ASP.NET website, are static classes unique to each web request, or are they instantiated whenever needed and GCed whenever the GC decides to disposed of them? The reason I ask is because I've written some static classes before in C# and the behavior is different than I would have expected. I would have expected static classes to b...
