I am trying to do a search on a datagridview from a string the operator enters into a textbox. I am searching the datagrid view on a sorted column of last names. I do not want to filter the datagridview. I would like the operator to be able to search for partial matches. As an example: If the operator is searching for the last name of wilson, they should be able to enter w, wi, wil, wils, wilso, or wilson into the text box and search the last name column for the first row that matches their entry. In this way if they search for "wil" they might land on a row and select it that has the last name of williams when they are actually looking for wilson. They will then be able to scroll down to the row they are looking for and select it. Sometimes the last names are misspelled and other times they operator may not be able to spell the last name.
The code I have will find the last name but only if it is a complete match. Can anyone help me with this?
Dim Found As Boolean = False
Dim StringToSearch As String = ""
Dim ValueToSearchFor As String = Me.TextBox1.Text.Trim.ToLower
Dim CurrentRowIndex As Integer = 0
If DataGridView1.Rows.Count = 0 Then
CurrentRowIndex = 0
CurrentRowIndex = DataGridView1.CurrentRow.Index + 1
If CurrentRowIndex > DataGridView1.Rows.Count Then
CurrentRowIndex = DataGridView1.Rows.Count - 1
If DataGridView1.Rows.Count > 0 Then
For Each gRow As DataGridViewRow In DataGridView1.Rows
StringToSearch = gRow.Cells(1).Value.ToString.Trim.ToLower
If StringToSearch Like (Me.TextBox1.Text) Then
Dim myCurrentCell As DataGridViewCell = gRow.Cells(1)
Dim myCurrentPosition As DataGridViewCell = gRow.Cells(0)
DataGridView1.CurrentCell = myCurrentCell
CurrentRowIndex = DataGridView1.CurrentRow.Index
DataGridView1.CurrentRow.DefaultCellStyle.BackColor = Color.LightSkyBlue
Found = True
If Found Then
