Dev控件用法 aspxTreeList 无刷新 aspxGridView 数据

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 

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
