Я использую это в VB.NET. Вы можете использовать http://www.developerfusion.com/tools/ для преобразования в C Sharp.
Я написал метод, который будет выбирать набранную букву строки. Функция вызывается в обработчике событий KeysPress DataGridView.
Метод:
'user types letter in dgv, method will select the column starting with that letter if it exists or else next letter existing in dgv
Public Shared Sub GoToLetterTypedInDataGridView(ByVal dgv As DataGridView, ByVal columnName As String, ByVal columnPosition As Integer, ByVal letterTyped As Char)
Try
Dim dt As DataTable = dgv.DataSource
Dim letter As Char = letterTyped
Dim dv As DataView = New DataView(dt)
Dim hasCount As Boolean = False
While (Not hasCount)
dv.Sort = columnName
dv.RowFilter = columnName & " like '" & letter & "%'"
If dv.Count > 0 Then
hasCount = True
Dim x As String = dv(0)(columnPosition).ToString()
Dim bs As New BindingSource
bs.DataSource = dt
dgv.BindingContext(bs).Position = bs.Find(columnName, x)
dgv.CurrentCell = dgv(0, bs.Position)
Else
If letter = "z" Then
letter = "a"
ElseIf letter = "Z" Then
letter = "A"
Else : letter = Chr(Asc(letter) + 1)
End If
End If
End While
Catch ex As Exception
Dim stackframe As New Diagnostics.StackFrame(1)
Throw New Exception("An error occurred in routine, '" & stackframe.GetMethod.ReflectedType.Name & "." & System.Reflection.MethodInfo.GetCurrentMethod.Name & "'." & Environment.NewLine & " Message was: '" & ex.Message & "'")
End Try
End Sub
Тогда позвонить:
Private Sub dgvNew_KeyPress(sender As Object, e As System.Windows.Forms.KeyPressEventArgs) Handles dgvNew.KeyPress
Try
If dgvNew.RowCount > 0 Then
GoToLetterTypedInDataGridView(dgvNew, "columnName", 0, e.KeyChar)
End If
Catch ex As Exception
Dim stackframe As New Diagnostics.StackFrame(1)
Throw New Exception("An error occurred in routine, '" & stackframe.GetMethod.ReflectedType.Name & "." & System.Reflection.MethodInfo.GetCurrentMethod.Name & "'." & Environment.NewLine & " Message was: '" & ex.Message & "'")
End Try
End Sub
Надеюсь, это поможет!
