当我扫描当前行本身的条形码时，如何为当前行指定值 [英] How to assign values to current row when I scan barcode in the current row itself

问题描述

我有一个wpf数据网格，我创建了一个新行，我在第一列中扫描条形码，然后基于该条形码的产品应显示在winforms的第一行，我们可以使用dgv.currentrow.cells []。value。我不知道wpf你可以帮我吗



我尝试过：



TextBox tbbarcode =发送者为TextBox;

DataTable dt = new DataTable（）;



dt = blOrderDetails.getProductsonBarcode（转换.ToString（tbbarcode.Text））;



if（dt.Rows.Count> 0）

{

var item = dgvTextiles.SelectedItem as DataRowView;

if（item == null）return;



item.Row [ color] = dt.Rows [0] [color];

}

I had a wpf datagrid where I create a new row and I scan barcode in the firstcolumn then the products based on that barcode should be displayed on first row in winforms we can use dgv.currentrow.cells[].value . I donno about it in wpf can u help me

What I have tried:

TextBox tbbarcode = sender as TextBox;
DataTable dt = new DataTable();

dt = blOrderDetails.getProductsonBarcode(Convert.ToString(tbbarcode.Text));

if (dt.Rows.Count > 0)
{
var item = dgvTextiles.SelectedItem as DataRowView;
if (item == null) return;

item.Row["color"] = dt.Rows[0]["color"];
}

推荐答案

这是一个很好的做法基础数据源而不是直接修改数据网格。

您已经创建了数据表，为什么不将它用作数据源？



它应该是这样的

C＃

It is a good practice to work on the underlying data source instead of modifying the data grid directly.
You have already created a data table so why not use it as the data source?

It should be something like this
C#

DataTable dtBarcodes = blOrderDetails.getProductsonBarcode(Convert.ToString(tbbarcode.Text));
dgvTextiles.DataContext = dtBarcodes.DefaultView;

XAML

XAML

<DataGrid Name="dgvTextiles" ItemsSource="{Binding}">
