无法设置数据绑定DataGridView添加列的值

Question

我有一个绑定在代码后面的DataGridView，我添加了一个列，然后我需要在同一行的基于列的列中插入数据。

 Dim db2 As New MyDBDataContext
 Dim r = (From p In db2.EventConfigs)
 GridTemplate.DataSource = r

我在网格中添加了一列

    Dim col As New DataGridViewTextBoxColumn
    col.ValueType = GetType(System.String)
    col.HeaderText = "SomeText"
    col.Name = "colWhateverName"
    GridTemplate.Columns.Add(col)

当我运行它时，网格正确显示，末尾有额外的列。我在这里遇到了一个问题：

 For Each row As DataGridViewRow In GridTemplate.Rows
        row.Cells.Item(11).Value = "Does Not Work"
        row.Cells.Item("colWhateverName").Value = "Also Does Not Work"
    Next

为什么网格显示列，但列的值为空。

Answer 1

你很亲密。取出项目（“colWhateverName”）并将其缩短为Cells（“colWhateverName”）。

尝试：

   For Each row As DataGridViewRow In dgvReports.Rows
            row.Cells("colWhateverName").Value = "Also Does Not Work"
        Next
