作者:Dezai.CN / 发布于2011/10/17/ 689

<div><--批量删除-->
<asp:linkbutton id="btnDeleteAll" onclick="btnDeleteAll_Click" runat="server" text="批量删除" onclientclick="javascript:return confirm('确定要删除所有选中项吗？')">
<--GridView的删除列-->
<asp:CommandField HeaderText="删除" ShowDeleteButton="True" />
<--全选模板列-->
<asp:TemplateField>
<HeaderTemplate>
<asp:CheckBox ID="CheckBox2" runat="server" OnCheckedChanged="CheckBox2_CheckedChanged" Text="全选" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox ID="CheckBox1" runat="server" />
</ItemTemplate>
<asp:/asp:TemplateField>
------GridView事件：GridView1_RowDataBound-----
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//鼠标经过时，行背景色变
//e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#E6F5FA'");
//鼠标移出时，行背景色变
//e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#FFFFFF'");

//当有编辑列时，避免出错，要加的RowState判断
if (e.Row.RowState == DataControlRowState.Normal || e.Row.RowState == DataControlRowState.Alternate)
{
//删除时确认
((LinkButton)e.Row.Cells[3].Controls[0]).Attributes.Add("onclick", "javascript:return confirm('你确认要删除：\"" + e.Row.Cells[0].Text + "\"吗?')");
}
}
//if (e.Row.RowIndex != -1)
//{
// int id = e.Row.RowIndex + 1;
// e.Row.Cells[0].Text = id.ToString();
//}
}
－－－－CheckBox事件：CheckBox2_CheckedChanged
protected void CheckBox2_CheckedChanged(object sender, EventArgs e)
{
CheckBox cball = (CheckBox)sender;
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox cb = (CheckBox)GridView1.Rows[i].Cells[4].Controls[1];
cb.Checked = cball.Checked;
}
}
－－－－批量删除事件：btnDeleteAll_Click
protected void btnDeleteAll_Click(object sender, EventArgs e)
{
MemPay pay = new MemPay();
for (int i = 0; i < GridView1.Rows.Count; i++)
{
CheckBox cb = (CheckBox)GridView1.Rows[i].Cells[4].Controls[1];
if (cb.Checked == true)
{
pay.DeletePayType(GridView1.DataKeys[i].Value.ToString());
}
}
GridView1.DataBind();
}
