ASP.NET 网格视图 C# 中绑定的行数据

Question

我有一个网格视图，需要从数据库绑定 IsActive field.But，它是 1 或 0。
错误显示System.InvalidCastException: 'Specified cast is not valid.'

网格

<asp:BoundField DataField="IsActive" HeaderText="Status">
                                    <ItemStyle Width="200px" />
                                </asp:BoundField>

代码

 protected void grid1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            if (((int)DataBinder.Eval(e.Row.DataItem, "IsActive") == 1))
            {
                e.Row.Cells[12].Text = "Active";

            }
            else
            {
                e.Row.Cells[12].Text = "Inactive";
          }

        }
    }

尝试先抓取基础数据项，然后检查它。

protected void grid1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    DataRowView rowView = null;
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        // Retrieve the underlying data item 
        rowView = (DataRowView)e.Row.DataItem;

        // Make sure we can parse and compare what we get.
        if (int.TryParse(rowView["IsActive"].ToString(), out int isActive) && isActive == 1)
        {
            e.Row.Cells[12].Text = "Active";

        }
        else
        {
            e.Row.Cells[12].Text = "Inactive";
        }

    }
}
