主要是利用 ASPxTreeList 点击事件回发服务器进行数据重新绑定
ASPxTreeList：
|
1

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

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
|
1
|
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代码如下：

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#回调方法：

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代码如下：
|

|
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#回调方法：

index = ASPxGridView1 的ASPxGridView1_HtmlRowPrepared 递加 |
