现象：1 cmbShukkasoko的text是All items text一部分时，click Combo3, cmbShukkasoko不能自动选择匹配的Item，但
click文本控件（非Combo）时正常（能自动选择匹配的Item）。
2 cmbShukkasoko的SelectedIndexChanged时，
cmbHaitatubin不能自动选择某一项。
*****I 服了GrapeCity.Win.Input ..........
答：在另一个事件combo_TextChanging里，使用了GrapeCity提供的Combo.FindString( ... )，该函数在某些情况不能
检索出对应的Item。结果每次设置SelectedIndex 时，Combo.Text改变，但combo_TextChanging里的Combo.FindString( ... )检索不出，导致e.Cancel = true。
