I want to create a RadGrid to use like a spreadsheet, where users can fill in the cells, add rows, and delete rows. We're doing that now with an Infragistics grid, which I want to replace. I've attached a pic of what it looks like, which I now want to do with a RadGrid (but with a comboxbox in the "Cost Center" field now).

After I created the columns, I ran the webpage, but the grid is blank -- it doesn't even show the column headers. All I want is an empty row for the user to enter values into (like my attached pic shows) after which they can add or delete rows. (I'll save/load the data into the grid later.)

My RadGrid is defined below, with various ColumnType and DataTypes. But when I run it, there's no grid on the page. What am I missing? Or is RadGrid meant only for display purposes? I found none of your demos allow the spreadsheet-like editing of cells, so am I using the wrong control?
