Question

我需要使用存储过程在数据库中修改一行数据。但是为了调用该存储过程，我需要知道每列的名称。如何确定列的名称？（硬编码不是一个选项，因为我们正在谈论很多可能改变其名称的列。）

编辑：鉴于接受的答案，看起来像恶魔杰克想要列的标题文本而不是绑定字段的名称

Answer 1

要获取列的标题文本，您可以使用：

string colText = grid.Columns [i] .HeaderText;

其中i是列的索引。

Answer 2

假设您正在使用BoundField列，您可以从GridView获取Columns集合并将其从（从DataControlField）转换为BoundField，获取DataField属性

Answer 3

                foreach (TableCell objCell in e.Row.Cells)
                {
                    if (objCell is DataControlFieldHeaderCell)
                    {
                        string HEADERTEXT = objCell.Text;

                    }
                 }

Answer 4

''' <summary>
''' Requires that the 'AccessibleHeaderText' property is set on the column in the aspx
''' </summary>
Private Function GetCellByName(ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs, ByVal colName As String) As System.Web.UI.WebControls.TableCell

    Dim result As TableCell = Nothing

    If e.Row.RowType = DataControlRowType.DataRow Then
        Dim grid As GridView = e.Row.NamingContainer
        Dim index As Integer = 0

        For i As Integer = 0 To grid.Columns.Count - 1
            If String.Compare(grid.Columns(i).AccessibleHeaderText, colName, True) = 0 Then
                index = i
                Exit For
            End If
        Next

        If index <= e.Row.Cells.Count Then
            result = e.Row.Cells(index)
        End If
    End If

    Return result

End Function

Answer 5

List<string> ColName = new List<string>();
foreach(DataColumn c in gridview.Columns)
{
     ColName.Add(c);
}

以编程方式确定GridView控件的列名？
