You can create a class e.g. MyGridCol that represents the column and create a collection of the columns. Read the google data feed and create the columns. Then you need to add the columns individually e.g. MyGridCol0, myGridCol1 .. as DataGridColumns in the code behind.
You cannot bind directly to a column collection.

A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
