Empty RadGrid Shows No Columns

[Jeremy Yoder]

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?

No, you can't use RadGrid like a spreadsheet, but you still can add, edit and delete records. It's not easy to explain all existing possibilities, so I'd suggest you to check RadGrid demo at http://demos.telerik.com/aspnet-ajax/grid/examples/overview/defaultcs.aspx (Insert/Update/Delete section). The fastest and easiest way is to use Automatic Operations

Interesting. Well, I guess that answers that. Maybe we'll have to stick with Infragistics for our edit grids... that'd be unfortunate.

Thanks for directing me to those demos -- I had not seen those. I'm surprised Telerik has no spreadsheet, but good to know. Thanks.
