How to add value to a cell in a datagridview using a query?
提问by David
I have a bound datagridview that has an unbound column. I'm using cellformatting to look up the Employee ID in the same row to return the employee's name from a different datatable.
我有一个绑定的 datagridview，它有一个未绑定的列。我正在使用 cellformatting 在同一行中查找员工 ID，以从不同的数据表中返回员工的姓名。
I get everything working fine, the only problem is that i can only get one part of the name to show either the first name, middel, last, but not all together.
我一切正常，唯一的问题是我只能让名称的一部分显示名字、中间名、姓氏，但不能全部显示。
This is the code i have so far (I'm very new to coding, all that i have so far has been from forums or research only, so please comment your answer):
这是我到目前为止的代码（我对编码很陌生，到目前为止我所拥有的只是来自论坛或研究，所以请评论您的答案）：
If dgvr.Cells(0).Value IsNot Nothing AndAlso dgvr.Cells(0).Value IsNot DBNull.Value Then
Dim empID As Integer = CInt(dgvr.Cells(0).Value)
Dim qry = From dr As PersonalObraDataSet.PersonalObRow In _PersonalObraDataSet.PersonalOb _
Where (dr.cdTrabajador = empID)
'If qry.Count > 0 Then
DataGridView1.Rows(e.RowIndex).Cells(1).Value = qry.First.Apellido1
'DataGridView1.Rows(e.RowIndex).Cells(2).Value = qry.First.Nombre2
End If
'End If

You can combine strings with & operator. It would be something like
您可以使用 & 运算符组合字符串。它会是这样的
DataGridView1.Rows(e.RowIndex).Cells(1).Value = qry.First.Nombre2 & " " & qry.First.Apellido1 & " " & qry.First.SegundoNombre3
