filtering works, then disappears
posted

 

Have a basic WebCombo with simple data.
I'm trying to filter the data as the user types.
It works only if what the user is typing is what the column value starts
with (e.g. if user types T-e-d, the row with 'Ted Redfern' is displayed)
If the user types R-e-d, the row with 'Ted Redfern' flashes, then
disappears, leaving an empty grid.
The strange thing is, if the user types R-e-d, then clicks the left or right
arrow, the correct row is displayed.

Below is my markup and code-behind. What is the issue?

Thanks.
