1.用GridView ButtonField列
<asp:ButtonField Text="审核" CommandName="pass"/>
后台处理事件 这个利用 这个自定义 事件的！
protected void gvCardInfo_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "pass")
{
int intRow = int.Parse(e.CommandArgument.ToString()); //获取当前所在行 int ID = Convert.ToInt32(gvCardInfo.DataKeys[intRow].Value.ToString()); string sql = "update Reserve set ReserveStatus=1 where ReserverID="+ID; if (sh.execCommand(sql)) { bing();
} }
}2 全选的效果！！
aspx代码中的这个注意下 checkbox给他启用autopostback
<asp:TemplateField> <HeaderTemplate> <asp:CheckBox ID="Cball" runat="server" OnCheckedChanged="Cball_CheckedChanged" AutoPostBack="true"/> </HeaderTemplate> <ItemTemplate> <asp:CheckBox ID="Cbsig" runat="server" /> </ItemTemplate> <ItemStyle HorizontalAlign="Center" /> </asp:TemplateField>后台
foreach (GridViewRow gr in gvCardInfo.Rows) { CheckBox cb = (CheckBox)gr.Cells[9].FindControl("Cbsig"); if (!cb.Checked) { cb.Checked=true; } else { cb.Checked = false; } }代码全部贴处理吧!!
