I have defined a columns in spread sheet manually named as :
- Newly build home?
- Date and Time
- M/F
How to write values for those columns. I have tried
row.Elements.Add(new ListEntry.Custom() { LocalName = "newlybuildhome?", Value = "Joe" });
row.Elements.Add(new ListEntry.Custom() { LocalName = "m/f", Value = "f" });
row.Elements.Add(new ListEntry.Custom() { LocalName = "dateandtime", Value = "26" });
service.Insert(listFeed, row);
I get exception that Blank rows cannot be written; use delete instead.
I have tried:
row.Elements.Add(new ListEntry.Custom() { LocalName = "Newly build home?", Value = "Joe" });
row.Elements.Add(new ListEntry.Custom() { LocalName = "M/F", Value = "Smith" });
row.Elements.Add(new ListEntry.Custom() { LocalName = "Date and Time", Value = "26" });
service.Insert(listFeed, row);
I get exception with response string :Attribute name "build" associated with an element type "gsx:Newly" must be followed by the ' = ' character.

I used other procedure to change the cell value in a batch.
The API supports updating an entire column, row, or other set of cells, in a single request. This is offered to improve performance over making large sets of individual requests. This process is called "batching requests"
A number of batch operations can be combined into a single request. The two types of batch operations supported are query and update. insert and delete are not supported because the cells feed cannot be used to insert or delete cells. Remember that the worksheets feed must be used to do that.
query and update can be combined in any size set, and sent to the API in a single request. The API responds with information on the status of each individual operation within the batch. For query requests, the result is the requested cell. For update requests, the result includes the manipulated cell with new values.
class BatchCellUpdater
{
// The number of rows to fill in the destination workbook
const int MAX_ROWS = 75;
// The number of columns to fill in the destination workbook
