Looping through DataGridView Cells
提问by Mr Bagder
I am creating a program that generates a bar code and then prints the shipping labels.
我正在创建一个生成条形码然后打印运输标签的程序。
I have a function that allows the user to upload a spreadsheet into the datagrid view. One of the column names is "Tracking Number".
我有一个功能，允许用户将电子表格上传到数据网格视图中。列名称之一是“跟踪编号”。
I would like to be able to loop through each cell that has a tracking number and then generate a barcode into a a new cell in a column called "barcode".
我希望能够遍历具有跟踪号的每个单元格，然后将条形码生成到名为“条形码”的列中的新单元格中。
I understand there is a loop function for this but I have never used it before.
我知道有一个循环函数，但我以前从未使用过它。
The code that generates the barcode is the following , it calls two classes:
生成条码的代码如下，调用了两个类：
Image barc = Rendering.MakeBarcodeImage(txtTrack.Text, int.Parse(txtWidth.Text), true);
pictBarcode.Image = barc;
Any Help would be much appreciated. I will happily answer any other questions.
任何帮助将非常感激。我很乐意回答任何其他问题。

You can loop through a DataGridViewusing the following:
您可以DataGridView使用以下方法循环遍历 a ：
foreach (DataGridViewRow row in dgvNameOfYourGrid.Rows)
{
if (row["Tracking Number"].ToString != "")
{
string trackingNumber = row.Cells["Tracking Number"].ToString();
// do stuff with the tracking number
}
}
But to display the barcode in another cell you will need to convert it to a DataGridViewImageCell(or preferable the whole column into a DataGridViewImageColumn).
但是要在另一个单元格中显示条形码，您需要将其转换为 a DataGridViewImageCell（或者最好将整个列转换为 a DataGridViewImageColumn）。

To iterate through every cell, you can use foreach loops
要遍历每个单元格，您可以使用 foreach 循环
foreach(DataGridViewRow row in yourDataGridView.Rows)
{
foreach(DataGridViewCell cell in row.Cells)
{
//do operations with cell
}
}
