WPF在排序的数据网格上获取选定的单元格 [英] WPF get selected cells on sorted datagrid

问题描述

你好

如何获取选定的行-然后将每个(可见)单元格分别放在已排序的数据网格上?

类似datagrid.SelectedCells [i] [j]，但要考虑排序.

谢谢

解决方案

我认为您可能想尝试DataGrid.CurrentItem属性. CurrentItem属性获取绑定到包含当前单元格的行的数据项.

http://msdn.microsoft.com/zh-CN/library/system.windows.controls.datagrid.currentitem ％28VS.95％29.aspx

这里是使用它的示例.

public 部分 类 Window1 :窗口

私有 DataTable dt = 新 DataTable ();

公共 Window1()

"Column1" );

"Column2"; );

用于( int i = 0; i< 10; i ++)

项目" + i.ToString());

新 EventHandler < EventArgs >(dataGrid1_CurrentCellChanged);

无效 dataGrid1_CurrentCellChanged(对象发​​送者， EventArgs e)

DataRowView drv =( DataRowView )dataGrid1.CurrentItem;

字符串 cellOfColumn1 = drv [0] .ToString();

字符串 cellOfColumn2 = drv [1] .ToString();

在此示例中，我将DataGrid1与DataTable绑定.当我更改选择时，将触发CurrentCellChanged，并通过CurrentItem属性获得选择了哪个项目.它是一个 在此示例中为DataRowView实例.因此，我可以将其转换为DataRowView并获取每个单元格的值.希望能帮助到你.

此致，

hello,

how can i get the selected rows - and then each (visible) cell separately on a sorted datagrid?

something like datagrid.SelectedCells[i][j], but with sorting taken onto account.

Thanks

Hi immuner,

 

I think you might want to try DataGrid.CurrentItem property. The CurrentItem property gets the data item bound to the row that contains the current cell.

http://msdn.microsoft.com/en-us/library/system.windows.controls.datagrid.currentitem%28VS.95%29.aspx

 

Here is a sample to use it.

public partial class Window1 : Window

    {

        private DataTable dt = new DataTable();

 

        public Window1()

        {

            InitializeComponent();

            dt.Columns.Add("Column1");

            dt.Columns.Add("Column2");

            for (int i = 0; i < 10; i++)

            {

                dt.Rows.Add(i, "Item" + i.ToString());

            }

            dataGrid1.ItemsSource = dt.DefaultView;

            dataGrid1.CurrentCellChanged += new EventHandler<EventArgs>(dataGrid1_CurrentCellChanged);

        }

 

        void dataGrid1_CurrentCellChanged(object sender, EventArgs e)

        {

            DataRowView drv = (DataRowView)dataGrid1.CurrentItem;

            string cellOfColumn1 = drv[0].ToString();

            string cellOfColumn2 = drv[1].ToString();

        }

    }

In this sample, I bind the DataGrid1 with a DataTable. When I change the selection, CurrentCellChanged fires and I get which item is selected via CurrentItem property. It is a DataRowView instance in this example. So I can convert it to DataRowView and get each cell’s value. Hope it helps.

 

Sincerely,
