VB.NET tutorial: Make search box workable
Make search box workable
To make the search box workable you need the following code that is applied to the TextChanged event of the text box:
Private Sub Txtbox_TextChanged(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Txtbox.TextChanged
When a user types a word in the search text box TxtBox, This word is used to compare with a word in the list box. If the words are matched the word in the list will be selected and its translation will display in the rich text box Txtresult. The highlight() procedure is called to change colors of the English key terms in the rich text box Txtresult. This procedure will be discussed in the next phase.
If the user chooses to select from the list rather than typing in to the search box, you need another piece of code applied to the SelectedIndexChanged event of the list box:
Private Sub Lstterms_SelectedIndexChanged(ByVal sender As System.Object,
ByVal e As System.EventArgs) Handles Lstterms.SelectedIndexChanged
Note: The DataRow dr is used to get data of a selected row of the table.
