add items to an already existing combobox cell in a datagridview comboBox column
提问by user2194838
How can I add items to an already existing combobox cell in a datagridview combobox column. ProductGrid is dataGridView.
如何将项目添加到 datagridview 组合框列中已经存在的组合框单元格。ProductGrid 是 dataGridView。
With ProductGrid
Dim objSerialNumber As New DataGridViewTextBoxColumn
With objSerialNumber
.Name = "SerialNumber"
.HeaderText = "SerialNumber"
.Visible = False
.Width = lGridWidth * 1.2
End With
.Columns.Add(objSerialNumber)
End With
There is another function where i have to add items in SerialNumber comboBox. And item that i have to add is in array. And which line of code will be used to remove items from comboBox if already added in ComboBox column.
还有另一个功能，我必须在 SerialNumber 组合框中添加项目。我必须添加的项目在数组中。如果已经添加到 ComboBox 列中，哪一行代码将用于从组合框中删除项目。

I solved the problem stated above in this manner. gSerialNumberArray contains items that i have to add.
我以这种方式解决了上述问题。gSerialNumberArray 包含我必须添加的项目。
Dim cbCell As New DataGridViewComboBoxCell
For k = 0 To ProductGrid.Rows.Count - 1
cbCell = ProductGrid.Rows(k).Cells("SerialNumber")
For iIndex = 0 To UBound(gSerialNumberArray)
cbCell.Items.Add(gSerialNumberArray(iIndex))
Next
Next

Normally combobox add item Command is applicable instead of using your DatagridviewCombobox Cell Name
通常组合框添加项目命令是适用的，而不是使用您的 DatagridviewCombobox 单元格名称
dgvcomb.Items.Add("30")

Column4.Items.Add(tds1.Tables(0).Rows(ij).Item(0))
Column4.Items.Add(tds1.Tables(0).Rows(ij).Item(0))

You can also use:
您还可以使用：
cbCell.Items.AddRange(strArray)
cbCell.Items.AddRange(strArray)
If you already loaded the items into an array, this loads them all in the pulldown. If you are collecting them from say a database table, use the arraylist function to load the database items into the list, then convert the array list to an array.
如果您已经将项目加载到数组中，这会将它们全部加载到下拉列表中。如果您从数据库表中收集它们，请使用 arraylist 函数将数据库项加载到列表中，然后将数组列表转换为数组。
