如何从WPF中的数据网格中选择数据 [英] how to select data from datagrid in WPF

问题描述

先生，

我想从WPF中的DataGrid到TextBox接收数据(数据网格中的一行). DataGrid已从数据库(SQL Server)中的表中获取值.

单击特定行时，我想在DataGrid至TextBox中选择一行

我写的代码如下:

Sir,

I want to take data (a row in the datagrid) from DataGrid in WPF to TextBox. The DataGrid has taken the values from a table in the database (SQL Server).

I want to select a row in the DataGrid to TextBox when click on the particular row

I wrote the code as follows:

private void branchdg_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    txtbranchcode.Text = branchdg.SelectedItem.ToString();
}

但它会将输出作为System.Data.DataRowView提供给TextBox.

这可能很简单，但是请帮帮我

提前致谢...

but it gives the output as System.Data.DataRowView to the TextBox.

It may be very simple, but pls help me

Advance thanks...

推荐答案

如果已将datagrid设置为允许选择，则该事件应具有选择更改事件.这将告诉您选择了哪一行.

The datagrid should have a selection changed event, if you''ve set it to allow selection. This will tell you what row is selected.

该项目是一个DataRowView，因此您将获得该内容.相反，您需要使用SelectedItem并从其中的列中获取数据.我通常建议您阅读一本有关C#的书，这样您将了解该结果的含义，并考虑阅读MSDN以了解如何使用您以前从未使用过的对象和方法.

The item IS a DataRowView, so that''s what you get. You need instead to take the SelectedItem and grab the data from the columns inside it. I suggest in general that you should read a book on C#, so you''d understand what this result means, and consider reading MSDN to learn how to use objects and methods you''ve not used before.
