datagrid的一些小技巧

1:dataGrid行随鼠标变色

 if (e.Item.ItemType == ListItemType.Item||e.Item.ItemType==ListItemType.AlternatingItem)
        {
            e.Item.Attributes.Add("onMouseOver", "this.style.backgroundColor='#FFCC66'");

            e.Item.Attributes.Add("onMouseOut", "this.style.backgroundColor='#ffffff'");

          
        }

2：datagrid不同条件显示不同背景颜色

 if ((e.Item.Cells[5].Text) == "Berlin")
        {
            e.Item.BackColor = Color.Blue;
        }

3：datagrid添加自动编号功能

 if (e.Item.ItemIndex != -1)
        {
            int orderID = e.Item.ItemIndex + 1;
            e.Item.Cells[0].Text = orderID.ToString();
        }

4:datagrid显示隐藏某一列

 protected void Button1_Click(object sender, EventArgs e)
    {
        if (DataGrid1.Columns[0].Visible == false)
        {
            DataGrid1.Columns[0].Visible = true;
        }
        else
            DataGrid1.Columns[0].Visible =false;
     
    }

5:datagrid添加删除确认

 protected void DataGrid1_ItemCreated(object sender, DataGridItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType ==ListItemType.EditItem)
        {
            TableCell mytablecell;
            mytablecell = e.Item.Cells[1];
            LinkButton mylinkbutton = (LinkButton)mytablecell.Controls[0];
            mylinkbutton.Attributes.Add("onclick", "return confirm('真要删除此行吗？')");
        }
    }
