Microsoft Dynamics CRM 2011 表单OnSave(ExecutionObj)、OnChange、PageOnLoad事件理解

一、OnLoad

/*
描述：部品更换单明细窗体上的选择退料部品按钮
在更换单明细中选择退料单，过滤条件为与更换单网点关联的新件不良换货类型的、
并且已更换数量小于收货数量的退料单。
自动带出退货部品代码、退货部品SN号、单价。
*/
function ReturninfoSelect() {
var replaceShopId = getPartsReplaceShopId();
var new_returns_sys_materialid = Xrm.Page.getAttribute("new_returns_sys_materialid"); //字段:退货部品代码
var new_return_snnum = Xrm.Page.getAttribute("new_return_snnum"); //退货部品S/N号
var new_price = Xrm.Page.getAttribute("new_price"); //单价
var new_returninfoid = Xrm.Page.getAttribute("new_returninfoid"); //退料单明细
if (replaceShopId != null) {
var url = "/ISV/Sharp_BatchSelect/ReturnpartsSelect.aspx?replaceShopId=" + replaceShopId;
}
var dialoghw = "dialogheight=455px;dialogwidth=500px;status=yes;scroll=no";
var returnValue = window.showModalDialog(url, null, dialoghw);
if (returnValue != null && typeof (returnValue) != undefined) {
var ls = returnValue.split('%');
if (ls.length > 0) {
if (ls[0] != "") {
var entityReference = getEntityReferenceObject(ls[0], "new_sys_material", ls[1])
new_returns_sys_materialid.setValue(entityReference);
new_returns_sys_materialid.fireOnChange();
new_returns_sys_materialid.setSubmitMode("always");
}

new_return_snnum.setValue(ls[2]);
new_return_snnum.setSubmitMode("always");

if (ls[3] != "") {
new_price.setValue(parseFloat(ls[3]));
}
else {
new_price.setValue(null);
}
new_price.setSubmitMode("always");

if (ls[4] != "") {
var entityReference = getEntityReferenceObject(ls[4], "new_returninfo", ls[5])
new_returninfoid.setValue(entityReference);
new_returninfoid.setSubmitMode("always");
}
}
}
}

1.ReturnpartsSelect页面代码：

C#：保存：

/// <summary>
/// 确定按钮按下后的事件处理
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
protected void btnSave_Click(object sender, EventArgs e)
{
Boolean isChecked = false;
string strReturn = string.Empty;
//获取选取个数
foreach (GridViewRow gr in ReturnpartsGridView.Rows)
{
if (gr.FindControl("cbSelected") != null)
{
CheckBox ch = (CheckBox)gr.FindControl("cbSelected");
if (ch.Checked)
{
isChecked = true;
// 部品ID
string new_sys_materialid = ReturnpartsGridView.DataKeys[gr.DataItemIndex].Value.ToString();
// 部品名称
string new_sys_materialName = (gr.FindControl("lblName") as Label).Text;

//单据编号
string new_sys_materialName1 = (gr.FindControl("lblName1") as Label).Text;
// S/N号
string new_snnum = (gr.FindControl("lblSnNum") as Label).Text;
// 价格
string new_price = (gr.FindControl("lblPrice") as Label).Text;

//退料单明细
string new_returninfoid = (gr.FindControl("lblNewReturninfoId") as Label).Text;

//退料单名称
string news_name = (gr.FindControl("lblNewsName") as Label).Text;

strReturn = new_sys_materialid + "%" + new_sys_materialName + "%" + new_snnum + "%" + new_price + "%" + new_returninfoid + "%" + news_name;
break;
}
}
}
if (!isChecked)
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Check", "alert('请选择部品！');", true);
return;
}

Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "Check", "setReturnValue('" + strReturn + "');", true);
}

二、OnSave

CRM 2011 当出现条件不满足的时候,需要在PageOnSave事件里面传一个参数 ExecutionObj 参数时候,请注意

alert提示信息后面必须紧跟ExecutionObj.getEventArgs().preventDefault();不然点击保存记录的时候，会出发其他事件，从而使ExecutionObj.getEventArgs().preventDefault()失效。具体如下：

比如：//表单OnSave事件

function PageOnSave(ExecutionObj) {

var newshipsysmaterial = Xrm.Page.getAttribute("new_ship_sys_material"); //getAttribute:发货部品代码
var serverPath = Xrm.Page.context.getServerUrl(); //获取路径
var new_shipped_snnum = Xrm.Page.getControl("new_shipped_snnum"); //获取发货部品S/N号
var entityName = "new_sys_material"; //物料实体
var newproductlinecode = "";
if (newshipsysmaterial != undefined && newshipsysmaterial.getValue()[0].id != "" && newshipsysmaterial.getValue()[0].id != null) {
var retrieveResult =
retrieveMultipleEntity(serverPath,
entityName,
"new_sys_product_line_new_sys_material/new_product_line_code",
"new_sys_materialId eq (guid'" + newshipsysmaterial.getValue()[0].id + "') and statecode/Value eq 0",
"", "new_sys_product_line_new_sys_material", "", "");
}
if (retrieveResult == null || retrieveResult.statusText != "OK") {
alert("查询失败" + "(" + retrieveResult.response + ")");
return;
}
var new_product_line_code_arr = "";
new_product_line_code_arr = retrieveResult.response.results;
if (new_product_line_code_arr.length == 0) return;
if (new_product_line_code_arr[0].new_sys_product_line_new_sys_material == null) return;
newproductlinecode = new_product_line_code_arr[0].new_sys_product_line_new_sys_material.new_product_line_code;
if (newproductlinecode != null && newproductlinecode == "R1LK") {
new_shipped_snnum.setValue(null);
new_shipped_snnum.setDisabled(false); //可编辑
1.alert("该发货部品的产品线代码的值为液晶屏,发货部品S/N号需要手动输入!");
2.ExecutionObj.getEventArgs().preventDefault();

如果在1,2之间加入new_shipped_snnum.setDisabled(false); //可编辑

变成

1.alert("该发货部品的产品线代码的值为液晶屏,发货部品S/N号需要手动输入!");
new_shipped_snnum.setDisabled(false); //可编辑
2.ExecutionObj.getEventArgs().preventDefault();

那么点击保存，时，该保存功能就失效了。

}

三、onChange

var returnssysmaterialid = Xrm.Page.getAttribute("new_returns_sys_materialid");
new_returns_sys_materialid.fireOnChange();//触发字段new_returns_sys_materialid的onChange事件3
new_returns_sys_materialid.setSubmitMode("always");

3.//onchange事件
function newreturnssysmaterialidOnChange() {
..//处理逻辑
}
