显示空文本框以接受 windows 应用程序中的值

Question

想要在 VB 中的 windows 应用程序的 DataGridView 的每一行中添加空文本框，以接受输入值以及使用集合的数据绑定。

Private Sub CreateTableStyle()
    With grdViewer
        Dim colDesc As New DataGridViewTextBoxColumn
        With colDesc

            .DataPropertyName = "Description"
            .HeaderText = "Description"
            '.Width = 350
            .ReadOnly = True
            .HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter

            .DefaultCellStyle.Alignment = DataGridViewContentAlignment.TopLeft
            .DefaultCellStyle.WrapMode = DataGridViewTriState.True
            .Name = "colDescription"
            .Resizable = DataGridViewTriState.True
            .AutoSizeMode = DataGridViewAutoSizeColumnMode.None
        End With
        .Columns.Add(colDesc)

        Dim colAssigned As New DataGridViewCheckBoxColumn
        With colAssigned
            .DataPropertyName = "Assigned"
            .HeaderText = "Assigned"
            .HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter
            '.Width = 5
            .ReadOnly = True
            .DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
            .Name = "colAssigned"
            .Resizable = DataGridViewTriState.True
            .AutoSizeMode = DataGridViewAutoSizeColumnMode.None
        End With
        .Columns.Add(colAssigned)

      Dim emptyTextColumn As New DataGridViewCheckBoxColumn
        With emptyTextColumn
            .HeaderText = "Enter Description"
            .HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleCenter
            '.Width = 5
            .ReadOnly = False
            .DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter
            .Name = "emptyTextColumn"
            .Resizable = DataGridViewTriState.True
            .AutoSizeMode = DataGridViewAutoSizeColumnMode.None
        End With
        .Columns.Add(emptyTextColumn)
        
     .DataSource = collectionPM

    End With

End Sub

正在将数据从数据库绑定到此 DataGridView，并且还想在 DataGridView 的每一行中添加文本框作为单独的列以接受用户对每一行的输入。

您只需将另一列添加到您的代码中，而不设置其 DataPropertyName 属性。在设置 DataSource 之前或之后都没有关系。就我个人而言，我建议您删除该代码并在设计器中创建列，除非有特定原因不能这样做。
