主要是利用 ASPxTreeList 点击事件回发服务器进行数据重新绑定

aspxTreeList:

<SettingsBehavior ExpandCollapseAction="NodeDblClick" AllowFocusedNode="True" AllowSort="False" /> <ClientSideEvents FocusedNodeChanged="function(s, e) { onFocusChanged(s,e);}" Init="function(s, e) { }" />

JS:

if ($("ASPxTreeList1") != null) { if (ASPxTreeList1.GetFocusedNodeKey != null || ASPxTreeList1.GetFocusedNodeKey != undefined) { key = ASPxTreeList1.GetFocusedNodeKey(); } } ASPxTreeList1.PerformCustomDatacallback(key); //数据传输回调方法 ASPxTreeList1.PerformCustomCallback(key); //数据绑定回调方法

ASPxGridView:

oncustomcallback="ASPxGridView1_CustomCallback"

js中的performcallback方法捎带的参数来进行aspxgridview数据更新,通过aspxgridview的customcallback来实现

js:

function onFocusChanged(s,e) { var key = ""; if ($("ASPxTreeList1") != null) { if (ASPxTreeList1.GetFocusedNodeKey != null || ASPxTreeList1.GetFocusedNodeKey != undefined) { key = ASPxTreeList1.GetFocusedNodeKey(); } } ASPxGridView1.PerformDataCallback(key); //数据传输回调方法  ASPxGridView1.PerformCallback(key); //数据绑定回调方法 }

C#:

protected void ASPxGridView1_CustomCallback(object sender, ASPxGridViewCustomCallbackEventArgs e) { string parm = e.Parameters.Trim(); //有的时候参数可能带有 "," 需要做判断 try { if (!string.IsNullOrEmpty(parm)) { ASPxGridView1.DataSource = ModuleCode.SelectModuleQuery(parm).Tables[0]; ASPxGridView1.DataBind(); } } catch (Exception ex) { } }

获取ASPxGridView1选择行的值

KeyFieldName="POSTCODEID" PreviewFieldName="POSTNAME,State,IsDelete"> <ClientSideEvents FocusedRowChanged="function(s, e) { OnGridFocusedRowChanged(); }"/> <dxwgv:GridViewDataDateColumn Caption="岗位" FieldName="POSTCODE"></dxwgv:GridViewDataDateColumn>

每个项 FieldName="POSTCODE" 隐藏也能取到值

js:

function OnGridFocusedRowChanged(index) { ASPxGridView1.GetRowValues(index, 'POSTCODEID;POSTNAME;POSTCODE;State;IsDelete', OnGetRowValues); } // 处理服务器端传回的数据(values是个数组) function OnGetRowValues(values) {}

C#:

index = ASPxGridView1 的ASPxGridView1_HtmlRowPrepared 递加
