How to get a value from a column in a DataView?

Question

I have a dataview defined as:

DataView dvPricing = historicalPricing.GetAuctionData().DefaultView;

This is what I have tried, but it returns the name, not the value in the column:

dvPricing.ToTable().Columns["GrossPerPop"].ToString();

Answer 1

You need to specify the row for which you want to get the value. I would probably be more along the lines of table.Rows[index]["GrossPerPop"].ToString()

Answer 2

You need to use a DataRow to get a value; values exist in the data, not the column headers. In LINQ, there is an extension method that might help:

string val = table.Rows[rowIndex].Field<string>("GrossPerPop");

or without LINQ:

string val = (string)table.Rows[rowIndex]["GrossPerPop"];

(assuming the data is a string... if not, use ToString())

If you have a DataView rather than a DataTable, then the same works with a DataRowView:

string val = (string)view[rowIndex]["GrossPerPop"];
