Display Find Task results in Dojo DataGrid programatically

Discussion created by phase on Jan 30, 2012

Hello, I have been able to display find task results in enhancedgrid programatically.

However, the onRowClickHandler() refuses to work.

Furthermore, I would like to be able to use a combobox to select individual findTasks.

I would very much prefer utilize the sample which returns results from multiple services but this sample does not allow onRowClickHandler() either.

Any assistance would be greatly appreciated.
