数据网格视图事件 [英] Data grid view events

问题描述

我正在使用datagrid视图中的复选框列.
在选中特定行的复选框时，我想将该行的背景色设置为其他颜色，然后取消选中，将其设置为白色.
我应该在哪个datagrid事件上编写代码?

还有另一件事如何获取复选框的选中状态的值，即在任何datagrid事件中是否选中(真或假)?

希望找到解决方案.

I am Using a checkbox column in datagrid view.
On checking the checkbox of a particular row I want to set the back color of that row to different color and on uncheck, back to white.
On which event of datagrid should I write the code?

And one more thing how to get value of checked state of checkbox i.e. whether it is checked or not (true or false) in any event of datagrid?

Hoping for a solution.

Manoj，

Hi Manoj,

On cell content click.

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex != -1)
            {
                if (e.ColumnIndex != 1)
                {
                    if (dataGridView1.Columns[e.ColumnIndex].Name = "colCheckBox")
                    {
                        if ( Convert.ToBoolean (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value == true )
                        {
                            //do this
                        }
                        else
                        {
                            //do do that
                        }
                    }
                }
            }
        }

您想要这个吗?

You want this?

Private Sub DataGridView1_CellValueChanged(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellValueChanged
  If e.RowIndex < 0 Or e.ColumnIndex < 0 Then Exit Sub
  If e.ColumnIndex = 0 Then
    If DataGridView1.Rows(e.RowIndex).Cells(e.ColumnIndex).Value Then
      For Each c As DataGridViewCell In DataGridView1.Rows(e.RowIndex).Cells
        c.Style.BackColor = Color.Black
      Next
    Else
      For Each c As DataGridViewCell In DataGridView1.Rows(e.RowIndex).Cells
        c.Style.BackColor = Color.White
      Next
    End If
  End If
End Sub

我得到了答案单元格内容单击，我创建了该单元格的一个对象，并进行了进一步的编码.

I got the answer on cell content click i made an object of that cell and coded further like.....

Dim oCheck As DataGridViewCheckBoxCell
oCheck = datagrid.CurrentRow.Cells("colunmname")

If oCheck.EditingCellFormattedValue = True Then
 For iCount = 0 To datagrid.CurrentRow.Cells.Count - 1
  datagrid.CurrentRow.Cells(iCount).Style.BackColor = Color.Teal
 Next iCount
Else
 For iCount = 0 To datagrid.CurrentRow.Cells.Count - 1
  datagrid.CurrentRow.Cells(iCount).Style.BackColor = Color.White
  Next iCount
End If
