How to add a row datagridview data-bound control by a module
提问by Haytham Mtair
In my project I had to create a module, lets say it's name is "intjobs.vb",
and I want to call a sub in it which is called dorow.
在我的项目中，我必须创建一个模块，假设它的名称是“intjobs.vb”，我想在其中调用一个名为dorow.
Here is the module:
这是模块：
Module intjobs
Public Sub dorow(fldtype, fldid, flddlvl)
Dim fdt As New dataTDataSet.fieldsDataTable
Dim dr As DataRow = fdt.NewRow
dr.Item(0) = "del"
dr.Item(1) = "up"
dr.Item(2) = "down"
dr.Item(3) = fldtype
dr.Item(4) = False
dr.Item(5) = fldid.ToString
dr.Item(6) = flddlvl.ToString
fdt.Rows.Add(dr)
'Dim log As String = "Sub name: dorow {somevalue}"
'logger(2, log)
End Sub
End Module
So when I put this sub in the same windows form with the datagridview, it works perfectly, but it doesn't add any row when I use this module.
因此，当我将这个 sub 与 datagridview 放在同一个窗口表单中时，它可以完美运行，但是当我使用这个模块时它不会添加任何行。
Please help.
请帮忙。

You can achieve that by using the right Modifier:
您可以通过使用正确的Modifier来实现：
- Set the Modifierof the grid view as Public.
In the Moduleuse a code similar to this:
Public Sub Modify_Cross_Module(ByRef DataGrid As DataGridView, _ ByVal firstColumnVal As String, _ ByVal secondColumnVal As String) DataGrid.Rows.Add(firstColumnVal, secondColumnVal) End Sub
- 将网格视图的修改器设置为Public。
在模块中使用类似于此的代码：
Public Sub Modify_Cross_Module(ByRef DataGrid As DataGridView, _ ByVal firstColumnVal As String, _ ByVal secondColumnVal As String) DataGrid.Rows.Add(firstColumnVal, secondColumnVal) End Sub
You have to make sure that the DataGridvariable as ByRef.
您必须确保DataGrid变量为ByRef。
Whenyou call that sub, use the following code:
当您调用该 sub 时，请使用以下代码：
Modify_Cross_Module(DataGridView1, "FirstVal", "SecondVal")
Where DataGridView1is the DataGridView you want to add row to it.
其中DataGridView1是您要向其添加行的 DataGridView。
