fineui grid自定义选项框 带全选

已有 3185 次阅读2015-12-22 10:51 |个人分类:Fineui 分享

为什么要写这功能?
1 当你用可编辑列的时候,是不能用选择框的,这是ext设定的。
2 如果有不允许选择行,默认的选择框是没有这个功能的。

参考:
遍历asp.net控件

复选框全选

===========正文===========
grid中  注意可以把TextBox换成Hidden,便于后台取值;(可选)需要设置数据源增加CheckBoxField1
<f:CheckBoxField ColumnID="CheckBoxField1" DataField="CheckBoxField1" Width="60px" RenderAsStaticField="false" HeaderText="<input type='checkbox'  name='allcheck' id='allcheck'>" />
                                       <f:TemplateField HeaderText ="订单" Width="100px" >
                                            <ItemTemplate>
                                                <asp:TextBox ID ="tbxYuwen" runat ="server" Width ="80px"  Text='<% #Eval("orderid" ) %> '></asp:TextBox>
                                            </ItemTemplate>
                                        </f:TemplateField>



通过gird的_OnPreRowDataBound方法设置 CheckBox 是否可用
//设置选择框是否可用
    protected void rpt_Pro_Order_List_OnPreRowDataBound(object sender, GridPreRowEventArgs e)
    {
        FineUI. CheckBoxField cbf = rpt_Pro_Order_List.FindColumn("CheckBoxField1") as FineUI.CheckBoxField ;
     
       
        DataRowView row = e.DataItem as DataRowView;
        cbf.Enabled = row[ "oState"].ToString() == "等待仓库拣货" ;
    }





js代码设置全选联动
<script src="../../res/js/jquery.min.js"></script>
<script>

    F.ready(function () {
        $( "#allcheck").click(function () {
            //f-grid-checkbox unchecked//没选中
            //f-grid-checkbox //选中
            if ($("#allcheck" ).is(":checked")) {
                $( "[class='f-grid-checkbox unchecked']" ).removeClass('unchecked');
            } else {
                $( "[class='f-grid-checkbox']" ).addClass('unchecked');
            }
        });

        $( "[class='f-grid-checkbox']" ).bind("click", function () {
            //alert("子项取消选中");
            setallcheck();
        });

        $( "[class='f-grid-checkbox unchecked']" ).bind("click", function () {
            //alert("子项设置选中");
            setallcheck();
        });

       
    });

    function setallcheck() {
        //判断是否有没选中项
        //if ($("[class='f-grid-checkbox unchecked']").length > 0) {
        //    $("#allcheck").prop("checked", false);
        //} else {
        //    $("#allcheck").prop("checked", true);
        //}
        $( "#allcheck").prop("checked" , $("[class='f-grid-checkbox unchecked']").length == 0);
    }
</script>


后台获取选择数据

if (rpt_Pro_Order_List.Rows.Count == 0)
        {
            AlertError( "没有数据!" , false);
            return;
        }
        FineUI. CheckBoxField field1 = rpt_Pro_Order_List.FindColumn("CheckBoxField1") as FineUI.CheckBoxField ;

        StringBuilder sb = new StringBuilder();

        for (int i = 0; i < rpt_Pro_Order_List.Rows.Count; i++)
        {
            if (field1.GetCheckedState(i))
            {
                GridRow row = rpt_Pro_Order_List.Rows[i];
                System.Web.UI.WebControls. TextBox tbxYuwen = (System.Web.UI.WebControls.TextBox )row.FindControl("tbxYuwen");
                sb.Append( "," + tbxYuwen.Text);
            }
        }

        string ids = sb.ToString();
        if (ids.Length == 0)
        {
            AlertError( "请选择订单" , false);
            return;
        }

        string OrderId = ids.Substring(1);
