如何根据DevExpress值选择GridView TextBox上的完整行？

我尝试了以下代码，但它无效：

Dim rowHandle As Integer = GridView1.LocateByDisplayText(0, colC_Id, txtSelect.Text)
If rowHandle <> DevExpress.XtraGrid.GridControl.InvalidRowHandle Then
    Dim row As System.Data.DataRow = GridView1.GetDataRow(GridView1.FocusedRowHandle)
    row(0) = txtSelect.EditValue
End If

该代码未在GridControl中选择一行。它对GridColumn colC_Id中的文本框中输入的文本进行区分大小写搜索，如果找到匹配项，GridControl数据源的第二列（列索引1）中的文本将更新为输入的文本。当前选中的行。如果数据源中的该字段已添加到GridControl的GridColumn集合中，则更新后的值将反映在GridControl中。

以下是如何根据GridControl的数据源为DataTable的特定值选择GridControl中的行的示例：

Dim myDataTable As DataTable = DirectCast(GridControl1.DataSource, DataTable)
Dim sFieldName As String = colC_Id.FieldName 
Dim sColumnName As String = colC_Id.Name
Dim myDataRows As DataRow() = myDataTable.Select(sFieldName & "='" & TextBox1.Text.Replace("'", "''") & "'")

If myDataRows.Length > 0 Then
    Dim iDataSourceRowIndex As Int32 = myDataTable.IndexOf(myDataRows(0))
    GridView1.FocusedRowHandle = GridView1.GetRowHandle(iDataSourceRowIndex)
Else
    MessageBox.Show("The text '" & TextBox1.Text & "' was not found in column '" & sColumnName &"'")
End If

根据TextBox值在DevExpress GridView上选择完整行
