嗨我有类似的代码。

Hi I have code something like that. <asp:UpdatePanel runat="server" ID="upUpdateCustodianTree" UpdateMode="Conditional"> <contenttemplate> <asp:UpdatePanel runat="server" ID="upApplyCustodianFilter" UpdateMode="Conditional"> <contenttemplate> <asp:ImageButton runat="server" ID="btnApplyCustodianFilter" OnClientClick="javascript:if(ShowInformation()){return true;}else{return false;};" OnClick="btnApplyCustodianFilter_click" AlternateText="Apply" CssClass="apply" ToolTip="Apply" ImageUrl="~/Images/apply.gif" onmouseover="this.src='../Images/apply-over.gif';" onmouseout="this.src='../Images/apply.gif';" /> <asp:ImageButton runat="server" ID="btnResetCustodianFilter" OnClientClick="javascript:if(ShowInformation()){return true;}else{return false;};" OnClick="btnResetCustodianFilter_click" AlternateText="Reset" ToolTip="Reset" ImageUrl="~/Images/reset.gif" onmouseover="this.src='../Images/reset-over.gif';" onmouseout="this.src='../Images/reset.gif';" /> <asp:ImageButton runat="server" ID="btnToggle" OnClientClick="return ToggleChecks(RadTreeViewCustodian1);" AlternateText="Toggle" ToolTip="Toggle" ImageUrl="~/Images/toggle.jpg" onmouseover="this.src='../Images/toggle-over.jpg';" onmouseout="this.src='../Images/toggle.jpg';" /> < telerik：RadToolTipManager Width =130pxSkin =Sunset高度=60pxRelativeTo =元素 ID =RadToolTipManagerCustodianrunat =serverOffsetX =15HideDelay =1000 位置=MiddleRight EnableShadow =true> < telerik：RadTreeViewönClientNodeClicked=onClientNodeClickedID =RadTreeViewCustodian CheckChildNodes = trueTriStateCheckBoxes =truerunat =serverCheckBoxes =true> < nodetemplat e> <telerik:RadToolTipManager Width="130px" Skin="Sunset" Height="60px" RelativeTo="Element" ID="RadToolTipManagerCustodian" runat="server" OffsetX="15" HideDelay="1000" Position="MiddleRight" EnableShadow="true"> <telerik:RadTreeView önClientNodeClicked="onClientNodeClicked" ID="RadTreeViewCustodian" CheckChildNodes="true" TriStateCheckBoxes="true" runat="server" CheckBoxes="true"> <nodetemplate> <％＃Eval（CustodianName）。ToString（）％> <％＃Eval（CustodianName）。ToString（）。ToLower（）。StartsWith（project保管人）？ ：（+ Eval（CustodianFileCount）。ToString（）+/+ Eval（TotalCustodianFileCount）。ToString（）+）％> <%#Eval("CustodianName").ToString() %> <%# Eval("CustodianName").ToString().ToLower().StartsWith("project custodians") ?

and javascript code is as:

function ToggleChecks(RadTreeView) {

    var RadTreeView1 = $find(RadTreeView);

    if (RadTreeView1._nodeData[0] != undefined) {
        var node = '';
        for (var i = 0; i < RadTreeView1._nodeData[0].items.length; i++) {
            if (RadTreeView1._nodeData[0].items[i].text != null) {
                node = RadTreeView1._findItemByText(RadTreeView1._nodeData[0].items[i].text);
            }
            else {
                node = RadTreeView1._findItemByValue(RadTreeView1._nodeData[0].items[i].value);
            }
            if (RadTreeView1._nodeData[0].items[i].checked == true) {
                node.uncheck();
            }
            else {
                RadTreeView1._nodeData[0].items[i].checked = 1;
                node.check();
            }
        }


    }
    return false;
}

切换OnClientClick javascript事件检查树视图的几个节点但是在btnApplyCustodianFilter_click应用按钮后面的代码没有显示所选择的树视图节点。

请帮助。

On toggle OnClientClick javascript event few node of tree view are checked but at code behind on btnApplyCustodianFilter_click of apply button no nodes of treeview are showing selected.
Please help.

推荐答案

find（RadTreeView）;

if （RadTreeView1._nodeData [ 0 ]！= undefined）{
var node = ' ' ;
for （ var i = 0 ; i < RadTreeView1._nodeData [ 0 ]。items.length; i ++）{
if （RadTreeView1._nodeData [ 0 ]。items [i] .text！= null ）{
node = RadTreeView1._findItemByText（RadTreeView1._nodeData [ 0 ]。items [i]。文本）;
}
else {
node = RadTreeView1._findItemByValue（RadTreeView1._nodeData [ 0 ]。items [i]。 value ）;
}
if （RadTreeView1._nodeData [ 0 ]。items [i] 。已检查 == true ）{
node.uncheck（）;
}
else {
RadTreeView1._nodeData [ 0 ]。 items [i]。 checked = 1 ;
node.check（）;
}
}


}
返回 假;
}

find(RadTreeView); if (RadTreeView1._nodeData[0] != undefined) { var node = ''; for (var i = 0; i < RadTreeView1._nodeData[0].items.length; i++) { if (RadTreeView1._nodeData[0].items[i].text != null) { node = RadTreeView1._findItemByText(RadTreeView1._nodeData[0].items[i].text); } else { node = RadTreeView1._findItemByValue(RadTreeView1._nodeData[0].items[i].value); } if (RadTreeView1._nodeData[0].items[i].checked == true) { node.uncheck(); } else { RadTreeView1._nodeData[0].items[i].checked = 1; node.check(); } } } return false; }
