How to Set DataGridView Row Tag
提问by Alex
I am using a double click event on a listview that will add three columns to a datagridview. I'm not sure how to set the "Tag" property on the "selectedText" variable.
我在列表视图上使用双击事件，它将向数据网格视图添加三列。我不确定如何在“selectedText”变量上设置“Tag”属性。
Private Sub lwArticles_DoubleClick(sender As Object, e As System.EventArgs) Handles lwArticles.DoubleClick
Dim selectedText = lwArticles.SelectedItems(0).SubItems.Item(0).Text 'Article No
Dim selectedDesc = lwArticles.SelectedItems(0).SubItems.Item(1).Text 'Description
Dim currRowNo As String = ""
Dim alreadyExists = False
For i As Integer = 0 To dgvDetail.Rows.Count - 1
currRowNo = dgvDetail.Rows(i).Cells(0).Value
If currRowNo = selectedText Then
alreadyExists = True
dgvDetail.Rows(i).Cells(2).Value += 1
Exit For
End If
Next
'If the entry doesn't exist, add it
If Not alreadyExists Then
dgvDetail.Rows.Add(New String() {selectedText, selectedDesc, 1})
End If
End Sub
After this I loop through the row's tags to see the article numbers. It will be near my dgvDetail.Rows.Add() that I should be setting the Tag property to equal the selectedText ... Any one know how to do this?
在此之后，我遍历行的标签以查看文章编号。在我的 dgvDetail.Rows.Add() 附近，我应该将 Tag 属性设置为与 selectedText 相等......有人知道如何做到这一点吗？
Edit: The datagridview columns being populated are: "Article Number", "Description" and "Quantity". The quantity is set in the loop, basically if I've double clicked on the same thing twice, it will increment the third column (Cell(2)) by one.
编辑：填充的 datagridview 列是：“文章编号”、“描述”和“数量”。数量在循环中设置，基本上如果我双击同一件事两次，它会将第三列 (Cell(2)) 增加一。

The Add "function" for the DataGridView control returns the index of the row in the grid, so you can try using that to reference the row:
DataGridView 控件的添加“函数”返回网格中行的索引，因此您可以尝试使用它来引用该行：
Dim rowIndex As Integer
rowIndex = dgvDetail.Rows.Add(New String() {selectedText, selectedDesc, 1})
dgvDetails.Rows(rowIndex).Tag = selectedText
