在datagridview中更改奇数行和偶数行的背景颜色？ [英] Change backcolor of odd and even rows in datagridview?

问题描述

我在数据网格视图中有10行，我使用VS2010。

如何更改奇数和偶数行的背景颜色不同？

我尽我所能但是我有一个错误是：

索引超出范围。必须是非负数且小于集合的大小。参数名称：index



我的代码在vb.net（windows窗体）中如下：

I have 10 rows in datagrid view and I use VS2010.
How can I change a backcolor of odd and even rows different?
I try my best but I have one error that is:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index

My code is in vb.net(windows form) as follows:

Dim CountR As Integer
CountR = 0
While CountR <= DataGridView1.RowCount          
  If CountR Mod 2 = 0 Then
    DataGridView2.Rows(CountR).DefaultCellStyle.BackColor = Color.Pink
  Else
    DataGridView2.Rows(CountR).DefaultCellStyle.BackColor = Color.SkyBlue
  End If
  CountR = CountR + 1
End While

推荐答案

for (int i = 0; i < GridView1.Rows.Count; i++)
                {
                    if (GridView1.Rows.Count % 2 == 0)
                    {
                        e.Row.Cells[0].BackColor = System.Drawing.Color.Green;
                        e.Row.Cells[1].BackColor = System.Drawing.Color.Green;
                       //here e.Row.Cells[1] from own database
                    }
                    else
                    {
                        e.Row.Cells[0].BackColor = System.Drawing.Color.Red;
                        e.Row.Cells[0].BackColor = System.Drawing.Color.Red;
                  
                    }

                }

DataGridView 有属性 AlternatingRowsDefaultCellStyle 和 RowsDefaultCellStyle 。



看看他们在MSDN或网络上你会找到很多例子。



祝你好运。 ：）

The DataGridView has properties AlternatingRowsDefaultCellStyle and RowsDefaultCellStyle.

Look them up on MSDN or the web and you'll find lots of examples.

Good luck. :)
