Comment	As explained in Grid reload, rows in a grid can be refreshed by either clicking on the reload toolbar button, or by modifying a value of a dependent customfield. The grid will then reload the data as detailed in the gd.query. The parameter gd.query.keepOnRefresh allows to specify what should happen with the existing rows. gd.query.keepOnRefresh = All All rows are kept, no data is removed gd.query.keepOnRefresh = Modified Only the modified rows are kept. A row is considered modified if a user changed some of its values during the current or previous edit. The rows which have not been modified will be removed. This is the default setting. gd.query.keepOnRefresh = None All rows are removed before reloading.
Example	`gd.query=select vendor,sandwichname,price from sandwichprices where vendor = \{0} gd.query.parameters=customfield:10150 gd.query.ds=gridds gd.query.keepOnRefresh=None`
