How to capture arrow keys in datagridview cell end edit in VB.net
提问by Matthew
Here is my code for Cell End Edit and Selection Changed event:
这是我的 Cell End Edit 和 Selection Changed 事件代码:
Private Sub dvJOBranch_CellEndEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles dvJOBranch.CellEndEdit
'get the current column and row index
curCol = e.ColumnIndex
curRow = e.RowIndex
'if the cell is blank, set it to zero
If IsDBNull(dvJOBranch.Rows(curRow).Cells.Item(curCol).Value) Then
dvJOBranch.Rows(curRow).Cells.Item(curCol).Value = 0
'convert it to integer
Else
dvJOBranch.Rows(curRow).Cells.Item(curCol).Value = _
Convert.ToInt32(dvJOBranch.Rows(curRow).Cells.Item(curCol).Value.ToString())
End If
'if the user do mouseclick in datagridview
isMouseClick = dvJOBranch.Capture.ToString()
'if the user does not click any cell from the datagridview
If isMouseClick = False Then
isEdited = True
iColumnindex = e.ColumnIndex
irowindex = e.RowIndex
If dvJOBranch.CurrentRow.Index = dvJOBranch.RowCount - 1 Then
If dvJOBranch.CurrentCell.ColumnIndex < dvJOBranch.ColumnCount - 1 Then
dvJOBranch.CurrentCell = dvJOBranch.Item(iColumnindex + 1, irowindex)
End If
isEdited = False
End If
End If
End Sub
Private Sub dvJOBranch_SelectionChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles dvJOBranch.SelectionChanged
'if the user does not click any cell from the datagridview
If isMouseClick = False Then
If isEdited Then
If dvJOBranch.CurrentCell.ColumnIndex < dvJOBranch.ColumnCount - 1 Then
dvJOBranch.CurrentCell = dvJOBranch.Item(iColumnindex + 1, irowindex)
Else
dvJOBranch.CurrentCell = dvJOBranch.Item(2, irowindex + 1)
End If
isEdited = False
End If
End If
'set it to false
isMouseClick = False
End Sub
The function of this code is to move the current cell to the right after editing using ENTER key, In my code I also capture the mouse click if the user click any cell because it has errors If i do not capture the mouse click, What I'm trying to do now is to capture the Arrow keys while I'm editing. Because after editing a cell, for example when I press Arrow key UP, it moves to the right like the Function for my ENTER key instead of moving upward.
此代码的功能是在使用 ENTER 键编辑后将当前单元格向右移动,在我的代码中,如果用户单击任何单元格,我也会捕获鼠标单击,因为它有错误如果我不捕获鼠标单击,我会做什么我现在要做的是在编辑时捕获箭头键。因为在编辑单元格后,例如当我按向上箭头键时,它会像我的 ENTER 键的功能一样向右移动,而不是向上移动。
Any help and guide will be appreciated, Thank you
任何帮助和指导将不胜感激,谢谢

You could be using the KeyUp event of the datagridview like this :
您可以像这样使用 datagridview 的 KeyUp 事件:
Private Sub dvJOBranch(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles dvJOBranch.KeyUp
If e.KeyCode = Keys.Up Then
' Do your code here
End If
End Sub
And if you want the enter key to be handled in there you could just use a select case also :
如果你想在那里处理回车键,你也可以使用一个选择案例:
Private Sub dvJOBranch(sender As Object, e As System.Windows.Forms.KeyEventArgs) Handles dvJOBranch.KeyUp
Select Case e.KeyCode
Case Keys.Enter
' Code for enter
Case Keys.Up
' Code for up arrow
'Etc
End Select
End Sub
