Making one column in DataGridView read only
提问by Charlie Stuart
Within my program i have included a datagridview that is filled when the form loads. When it first loads i have set the whole form to read-only. However if the user then wants to edit the data within it they can click an edit button i have included on the form, this has the code:
在我的程序中，我包含了一个在表单加载时填充的 datagridview。当它第一次加载时，我已将整个表单设置为只读。但是，如果用户然后想要编辑其中的数据，他们可以单击我在表单中包含的编辑按钮，其中包含以下代码：
datagrdSnippets.AllowUserToDeleteRows = True 'Allows user to delete rows
datagrdSnippets.ReadOnly = False 'Allows user to edit cells within the data grid
However i do not want one of the columns within the datagridview to be made editable, what code can i use to do this?
但是，我不希望将 datagridview 中的一列设为可编辑，我可以使用什么代码来执行此操作？

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Column1.ReadOnly = True
Column2.ReadOnly = True
Column3.ReadOnly = True
End Sub
set readonly true your desired column on form load event
在表单加载事件中设置 readonly true 您想要的列

Me, I have data source from database in my dataGridViewso I use for loop to get the exact column address that I want to make ReadOnly=trueand the rest is ReadOnly=false
我，我有来自数据库的数据源，dataGridView所以我使用 for 循环来获取我想要制作的确切列地址，ReadOnly=true其余的是ReadOnly=false
Code:
代码：
for i = datagridview1.columns.count - 1 to 0 Step -1
If i = (YourSpecificColumnAddress) Then
Datagridview1.columns(i).ReadOnly=true
Else
Datagridview1.columns(i).ReadOnly=false
End if
Next
