DataGrid生成空白行

Question

我正在用一些值填充DataTable（在定义列名之后），然后将其用作Sage Grid的数据源-功能上与WinForms DataGridView非常相似。

到目前为止，我已经尝试将数据类型添加到DataTable列，并使用DataTable填充BindingSource，然后将其绑定到Sage Grid。在调试时查看DataTable的内容时，可以使用DataSet Visualiser看到数据在那里。

创建数据表-

DataTable failedOrders = new DataTable();

failedOrders.Columns.Add("externalItemCodeColumn", typeof(String));
failedOrders.Columns.Add("reasonColumn", typeof(String));

foreach (String item in insufficientItemsAvailable)
{
    DataRow dataRow = failedOrders.NewRow();
    dataRow["externalItemCodeColumn"] = item;
    dataRow["reasonColumn"] = "Not enough available items in WAREHOUSE";

    failedOrders.Rows.Add(dataRow);
}

填充贤者网格-

Sage.Common.Controls.GridColumn externalItemCodeColumn = new Sage.Common.Controls.GridColumn();
externalItemCodeColumn.Caption = "External Item Code";
externalItemCodeColumn.DisplayMember = "externalItemCodeColumn";

Sage.Common.Controls.GridColumn reasonColumn = new Sage.Common.Controls.GridColumn();
reasonColumn.Caption = "Reason";
reasonColumn.DisplayMember = "reasonColumn";

failedOrdersGrid.Columns.Add(externalItemCodeColumn);
failedOrdersGrid.Columns.Add(reasonColumn);

failedOrdersGrid.DataSource = FailedOrders;
//failedOrdersGrid.Refresh(); - this doesn't seem to make a difference

请注意，failedOrders传递给了另一个方法，因此名称从failedOrders更改为FailedOrders。

只是为了检查这种行为是否不特定于Sage Grid，我尝试用DataTable填充常规WinForms DGV。 （注意-我禁用了AutoGenerateColumns，因为这似乎不是Sage Grid的选项。）

dataGridView1.AutoGenerateColumns = false;
dataGridView1.Columns.Add("externalItemCodeColumn", "External Item Code");
dataGridView1.Columns.Add("reasonColumn", "Reason");
dataGridView1.DataSource = FailedOrders;

我希望Sage Grid的内容与DataGrid的内容匹配，但是会得到空白行。

Sage.Common.Controls.Grid继承自Sage.Common.Controls.List和Sage.Common.Controls.List的DataSource属性，刷新时要求新的DataSource支持至少IList （实际上，它不是IList只会使您的数据源无效）

这是您的代码的改编版，可与Sage.Common.Controls.Grid一起使用

我将其添加到表单的构造函数中（failedOrdersGrid类型为Sage.Common.Controls.Grid）：

        List<Failure> failedOrders = new List<Failure>();

        foreach (String item in new List<string> { "1", "2", "3" })
        {
            failedOrders.Add(new Failure { externalItemCodeColumn = item, reasonColumn = "Not enough available items in WAREHOUSE" });
        }

        Sage.Common.Controls.GridColumn externalItemCodeColumn = new Sage.Common.Controls.GridColumn();
        externalItemCodeColumn.Caption = "External Item Code";
        externalItemCodeColumn.DisplayMember = "externalItemCodeColumn";

        Sage.Common.Controls.GridColumn reasonColumn = new Sage.Common.Controls.GridColumn();
        reasonColumn.Caption = "Reason";
        reasonColumn.DisplayMember = "reasonColumn";

        failedOrdersGrid.Columns.Add(externalItemCodeColumn);
        failedOrdersGrid.Columns.Add(reasonColumn);

        failedOrdersGrid.DataSource = failedOrders;

这是失败类：

public class Failure
{
    public string externalItemCodeColumn { get; set; }
    public string reasonColumn { get; set; }
}
