WPF Datagrid读取一个单元格值 [英] WPF Datagrid read a cell value

问题描述

我正在尝试找出如何读取WPF数据网格单元格的值。

I am trying to find out how to read the value of my WPF datagrid cells.

类似

String myString = myDataGrid.Cells[1][2].ToString();

已经在XAML中创建了datagrid，并且我已经通过使用

the datagrid has been created in XAML and i have populated the datagrid with row data by using

reportGrid.Items.Add(new cbResultRow() { ... });

现在我想返回并读取数据网格中的单元格值。

now I want to go back and read cell values in my datagrid.

我已经看到了一些从选定的行或单元格读取数据的示例，因为我没有任何选择（用户没有与数据网格交互）。

I have seen some examples of reading data from a selected row or cell, by I don't have any selection (the user doesnt interact with the datagrid).

我也看到过这样的代码

foreach(DataGridRow myrow in myDataGrid.Rows)

但是编译器说Rows不是datagrid的成员。

however the compiler says Rows is not a member of datagrid.

我搜索了几个小时，试图找出如何做我认为很简单的事情！

I have searched for several hours to try to find out how to do what I would have thought was a very simple thing!

请帮助，

谢谢，
会。

推荐答案

WPF数据网格旨在绑定到类似于DataTable。在大多数情况下，您将修改DataTable，以及DataTable中绑定到DataGrid的行/列。

The WPF datagrid was built to bind to something like a DataTable. The majority of the time, you will modify the DataTable, and the Rows/Columns within the DataTable that is bound to the DataGrid.

DataGrid本身是可视元素数据表。 这是一个很好的有关如何执行此操作的教程。在循环中修改数据看起来像这样。

The DataGrid itself is the Visual Element for the DataTable. Here is a pretty good tutorial on how to do this. To modify data within a loop would look something like this.

foreach(DataRow row in myTable.Rows)
{
    row["ColumnTitle"] = 1;
}

这只会使 ColumnTitle列中的所有值都等于1。要访问单个单元，它看起来应该像这样。

This would simply make all the values in Column "ColumnTitle" equal to 1. To access a single cell it would look something like this.

myTable.Rows[0][0] = 1;

这会将DataTable中的第一个单元格设置为1。

This would set the first cell in your DataTable to 1.
