 Hi. Welcome to BytesCount. Today we will show you how to change column width and roll using C-sharp. To begin, let's start by opening a Visual Studio app. Then put your code inside the Visual Studio. You will see the link of the sample code in the description box below. Next, let's add a reference to the spreadsheet SDK DLL. To do that, right-click on Reference in the Solution Explorer and click Add Reference. Then look for BytesCount Spreadsheet SDK. After adding the references, let's set the values of column width and height. Now let's run the program. Here's the result of the spreadsheet that we changed column width and row.
