什么是数据网格的MappingName对于非数据表的数据源？ [英] What is the DataGrid MappingName for a non DataTable DataSource?

问题描述

我能在我的.NET 3.5 CF DataGrid绑定到一个列表（），但我无法通过指定的宽度来格式化列。下面是code，它看起来像它应该工作，但没有。我是pretty的肯定，我不会设置的MappingName正确的，因为所有的教程告诉你，将其设置为你的数据表的名字，但我不是绑定到数据表中，所以我安静不知道该怎么做。

I am able to Bind my DataGrid in .NET 3.5 CF to a List() but I am unable to format the columns by specifying their width. Below is the code that looks like it should work but does not. I am pretty sure that I am not setting the MappingName correctly as all tutorials tell you to set it to the name of your DataTable but I am not binding to a DataTable so I am not quiet sure what to do.

            grdBatch.DataSource = InventoryItems;

        DataGridTableStyle tableStyle = new DataGridTableStyle();
        tableStyle.MappingName = InventoryItems.ToString();
        DataGridTextBoxColumn tbcName = new DataGridTextBoxColumn();
        tbcName.Width = 400;
        tbcName.MappingName = "SERIAL_ID";
        tbcName.HeaderText = "SERIAL_ID";
        tableStyle.GridColumnStyles.Add(tbcName);
        grdBatch.TableStyles.Clear();
        grdBatch.TableStyles.Add(tableStyle);

grdBatch是一个DataGrid和InventoryItems是波苏斯列表（平原旧的C＃对象）。

grdBatch is a DataGrid and InventoryItems is a List of POCOS(Plain old C# Objects).

推荐答案

修改

 tableStyle.MappingName = InventoryItems.ToString();

到

tableStyle.MappingName = InventoryItems.GetType().Name;
