set selected item in combobox - vb.net
提问by sharkyenergy
I am using this code to add a value to a combobox different then the one displayed: how to add value to combobox item
我正在使用此代码向与显示的组合框不同的组合框添加一个值：如何向组合框项目添加值
Lets suppose i have 3 values in my Combobox:
假设我的组合框中有 3 个值：
item 1
item 2
item 3
If i chose item 2from the dropdown the code in the link works. But if i TYPE item 2manually it doesnt work because i think that typing it only sets the combobox1.textvalue and not the combobox1.selecteditem. I can type a value present in the dropdown, or one not present. If i type one that is present, then the selectedItem property should also be set to the proper value. can this be done?
如果我item 2从下拉列表中选择，则链接中的代码有效。但是如果我item 2手动输入它不起作用，因为我认为输入它只会设置combobox1.text值而不是combobox1.selecteditem. 我可以在下拉列表中输入一个值，也可以输入一个不存在的值。如果我输入一个存在的值，则 selectedItem 属性也应设置为正确的值。可以这样做吗？
Thanks
谢谢

solved this way:
这样解决：
Private Sub ComboBox1_Keyup(sender As Object,
e As System.Windows.Forms.KeyEventArgs) Handles ComboBox1.KeyUp
ComboBox1.SelectedIndex = ComboBox1.FindStringExact(ComboBox1.Text)
End Sub
