Epicor系统二次开发
一、獲取或修改界面EpiDataView的字段數據（Get EpiDataView data）
C#
EpiDataView edv = (EpiDataView)oTrans.EpiDataViews["ViewName"];
if(edv.dataView.Count > 0)
{
string someValue = (string)edv.dataView[edv.Row]["FieldName"];
edv.dataView[edv.Row]["FieldName"] = someValue;
}
------------------------------------------------------------------------------------------------------------------------------------------------------
VB
Dim edv As EpiDataView = CType(oTrans.EpiDataViews("ViewName"), EpiDataView)
if edv.DataView.Count>0 then
dim someValue as string = [edv].dataView([edv].Row)("FieldName")
[edv].dataView([edv].Row)("FieldName") = someValue
end if
如果EpiDataView中有多行數據，例如incoming po suggestion或purchase suggestion，可以通過以下格式指定行號取得值
統計行數：edv.DataView.Count
取第100行的值：[edv].dataView(99)("FieldName")
二、獲取Session字段數據（Get Session data?）
C#
add reference Epicor.Mfg.Core.Session.dll
using Epicor.Mfg.Core;
string UserID = ((Epicor.Mfg.Core.Session)this.oTrans.Session).UserID;
string CompanyID = ((Epicor.Mfg.Core.Session)this.oTrans.Session).CompanyID;
E10
Ice.Core.Session.dll
using Ice.Core;
string UserID = ((Ice.Core.Session)this.oTrans.Session).UserID;
三、call adapter 調用adapter的GetByID方法，獲取adapter中的數據或更新數據，使用前必須先引用相應Adapter
C#
注意E10加Adapter需要在開始增加 using Erp.Adapters;
PartAdapter adpPart = new PartAdapter(this.oTrans);
adpPart.BOConnect();
adpPart.GetByID("PART0001");
string PartDescription = adpPart.PartData.Tables["Part"].Rows[0]["PartDescription"];
adpPart.PartData.Tables["Part"].Rows[0]["PartDescription"]="PART0001 xxxxxx";
adpPart.Update();
adpPart.Dispose();
VB
Dim adpPart As PartAdapter = New PartAdapter(oTrans)?
adpPart.BOConnect()
adpPart.GetByID("PART0001")
string PartDescription = adpPart.PartData.Tables("Part").Rows(0)("PartDescription")
adpPart.PartData.Tables("Part").Rows(0)("PartDescription")="PART0001 xxxxxx"
adpPart.Update()
adpPart.Dispose()
四、Search Data by Adapter 使用adapter查詢數據，使用前必須先引用相應Adapter
C#
PartAdapter adpPart = new PartAdapter(this.oTrans);
adpPart.BOConnect();
bool MorePages;
String whereClause = "PartNum='PART0001'";
SearchOptions opts = new SearchOptions(SearchMode.AutoSearch);
opts.NamedSearch.WhereClauses.Add("Part", whereClause);
DataSet dsPart = adpPart.GetRows(opts, out MorePages);
注意E10加Adapter需要在開始增加 using Erp.Adapters;
VB
Dim adpPart As PartAdapter = New PartAdapter(oTrans)
adpPart.BOConnect()
Dim MorePages As Boolean
Dim whereClause As String = "PartNum='PART0001'"
Dim opts As SearchOptions = New SearchOptions(SearchMode.AutoSearch)
opts.NamedSearch.WhereClauses.Add("Part", whereClause)
Dim dsPart As Data.DataSet = adpPart.GetRows(opts, MorePages)
五、Search Data by Epicor.Mfg.UI.FormFunctions.SearchFunctions 使用界面查詢功能查詢數據并返回值到當前界面EpiDataView，但數據列只有部分，類似于標準界面上的查詢功能，適用于快速查詢基本數據。
--使用Simple Search向導產生以下代碼
C#
bool recSelected;
string whereClause = string.Empty;
//"StartDate <= '" + ApplyDate.ToString("MM/dd/yyyy") + "'"; 如果是日期值轉換月日年格式后，兩邊要加單引號
System.Data.DataSet dsCurrencyAdapter = Epicor.Mfg.UI.FormFunctions.SearchFunctions.listLookup(this.oTrans, "CurrencyAdapter", out recSelected, true, whereClause);
if (recSelected)
{
// Map Search Fields to Application Fields
System.Data.DataRow adapterRow = dsCurrencyAdapter.Tables[0].Rows[0];
EpiDataView edvPODetail = ((EpiDataView)(this.oTrans.EpiDataViews["PODetail"]));
System.Data.DataRow edvPODetailRow = edvPODetail.CurrentDataRow;
if ((edvPODetailRow != null))
{
edvPODetailRow.BeginEdit();
edvPODetailRow["ShortChar10"] = Convert.ToString(adapterRow["CurrencyCode"]);
edvPODetailRow.EndEdit();
}
}
E10: Ice.UI.FormFunctions.SearchFunctions
發現這種方法不能取得ud field的值。
VB
Dim recSelected As Boolean
Dim whereClause As String = String.Empty
Dim dsResourceGroupAdapter As System.Data.DataSet = Epicor.Mfg.UI.FormFunctions.SearchFunctions.listLookup(Me.oTrans, "ResourceGroupAdapter", recSelected, False, whereClause)
If recSelected Then
Dim adapterRow As System.Data.DataRow = dsResourceGroupAdapter.Tables(0).Rows(0)
' Map Search Fields to Application Fields
Dim edvJobOpDtl As EpiDataView = CType(Script.oTrans.EpiDataViews("JobOpDtl"),EpiDataView)
Dim edvJobOpDtlRow As System.Data.DataRow = edvJobOpDtl.CurrentDataRow
If (Not (edvJobOpDtlRow) Is Nothing) Then
edvJobOpDtlRow.BeginEdit
edvJobOpDtlRow("Character01") = adapterRow("ResourceGrpID")
edvJobOpDtlRow.EndEdit
End If
End If
六、InvokeSearch 查詢數據，類似GetRows()
System.Collections.Hashtable myHash = new System.Collections.Hashtable();
string wClause = “Key1 = ‘“ + key1 + “‘“;
myHash.Add(“UD100A”, wClause);
SearchOptions opts = Epicor.Mfg.UI.Searches.SearchOptions.CreateRuntimeSearch(myHash,DataSetMode.RowsDataSet);
ud100Adapter.InvokeSearch(opts);
ucbCarrierSize.DataSource = ud100Adapter.UD100Data.UD100A;?
七、 EpiViewNotification 窗體事件，例如不允許訪問某供應商的PO
--選擇窗體事件向導產生以下代碼
C#
private void edvPOHeader_EpiViewNotification(EpiDataView view, EpiNotifyArgs args)
{
// ** Argument Properties and Uses **
// view.dataView[args.Row]["FieldName"]
// args.Row, args.Column, args.Sender, args.NotifyType
// NotifyType.Initialize, NotifyType.AddRow, NotifyType.DeleteRow, NotifyType.InitLastView, NotifyType.InitAndResetTreeNodes
if ((args.NotifyType == EpiTransaction.NotifyType.Initialize)) //選擇記錄的時候
{
if ((args.Row > -1))
{
//MessageBox.Show((string)view.dataView[args.Row]["VendorVendorID"]);
if((string)view.dataView[args.Row]["VendorVendorID"]=="S0000022")
{
oTrans.ClearDataSets();
//throw new UIException("不能訪問此供應商");
throw new Exception("不能訪問此供應商");?
//MessageBox.Show("不能訪問此供應商");
}
}
}
if ((args.NotifyType == EpiTransaction.NotifyType.AddRow)) //新加記錄的時候
{
if ((args.Row > -1))
{
//MessageBox.Show("EpiTransaction.NotifyType.AddRow");
}
}
}
八、Before Form change FormEvent args.ProposedValue及args.Row["UOMCode"]的區別，args.ProposedValue是操作時選擇的內容但args.Row["UOMCode"]是沒有值的。
private void PriceLstParts_BeforeFieldChange(object sender, DataColumnChangeEventArgs args)
{
switch (args.Column.ColumnName)
{
case "PartNum":
break;
case "UOMCode":
//MessageBox.Show(args.Row["UOMCode"].ToString().Length.ToString()+"/" + args.ProposedValue.ToString());
if(args.ProposedValue.ToString().Length>0)
{
bool ChkDupPart = CheckDupPartByListCode(args.Row["ListCode"].ToString(),args.Row["PartNum"].ToString());
if(ChkDupPart)
{
//MessageBox.Show("Duplicate Part: " + args.Row["PartNum"].ToString());
throw new Exception("Duplicate Part Not Allow. PartNum: " + args.Row["PartNum"].ToString());
}?
}
break;
}
}
?
throw new EpiUIException(); which library?
[Table/ViewName]_BeforeFieldChange() Handles DataTable.ColumnChanging event
This event handler is called before users can shift focus away from a field with changed data bound to a DataSource
and DataField. It performs the following events:
? This event handler can validate the entered value of a field.
? If the value is not valid, then you can prevent the user from leaving the field until a correct value is entered.
To prevent users from leaving a field that is not validated, you can use this C# code:
throw new EpiUIException();
?
epiUltraGrid 控件：
----Hidden UltraGrid Column 隱藏epiUltraGrid某列
C#
epiUltraGridC1.DisplayLayout.Bands[0].Columns[0].Hidden = true;
VB
epiUltraGridC1.DisplayLayout.Bands(0).Columns(0).Hidden = true
----Edit UltraGrid display ColumnName 修改epiUltraGrid列顯示名稱
C#
epiUltraGridReqSummary.DisplayLayout.Bands[0].Columns["Net_Req_Lots"].Header.Caption = "Net Req Shot [D/E]";
VB
epiUltraGridReqSummary.DisplayLayout.Bands(0).Columns("Net_Req_Lots").Header.Caption = "Net Req Shot [D/E]"
----select epiUltraGrid row 代碼選擇epiUltraGrid某一行并賦值
C#
epiUltraGridShipInfo.ActiveRow = epiUltraGridOnhandLotInfo.Rows[3];
epiUltraGridShipInfo.ActiveRow.Cells["ShipQty"].Value = 999;
將鼠標選中當前行
epiUltraGridShipInfo.ActiveRow.Selected = true
VB
epiUltraGridShipInfo.ActiveRow = epiUltraGridOnhandLotInfo.Rows(3)
epiUltraGridShipInfo.ActiveRow.Cells("ShipQty").Value = 999
將鼠標選中當前行
epiUltraGridShipInfo.ActiveRow.Selected = true
-----epiUltraGrid ActiveCell epiUltraGrid某單元格值發生改變之后
VB
Private Sub epiUltraGridC1_AfterCellUpdate(ByVal sender As Object, ByVal args As Infragistics.Win.UltraWinGrid.CellEventArgs)
Select Case args.Cell.Column.Key
Case "Character01"
......
End Select
End Sub
----Format epiUltraGrid Amount Column
C#
epiUltraGridC1.DataSource=adapterDynamicQuery.QueryResults;
epiUltraGridC1.DisplayLayout.Bands[0].Columns["EmpExpense.DocTotalExpenseAmt"].Format = "#,##0.00";
epiUltraGridC1.DisplayLayout.Bands[0].Columns["EmpExpense.DocTotalExpenseAmt"].CellAppearance.TextHAlign = Infragistics.Win.HAlign.Right;
----設置epiUltraCombo下拉顯示列寬
this.epiUltraComboLOB.DropDownWidth = 200;
----時間選擇
在系統中一般日期與時間是分開存儲，時間部分是使用數值字段存儲，例如自訂義字段Number01，例如客制化加入epiTimeEditor控件，綁定Number01，選擇時間是 10:15 AM，在系統保存此數據時，Number01的值自動是36900，計算方法：epiTimeEditor 10:15 AM = 10*3600 + 15*60 = store Database Integer 36900
----關閉窗體 窗體名.Close()
PartForm.Close()
?
----You can also create code that casts to a specific control type:
VB Code:
Dim eucSales As EpiUltraCombo = CType(csm.GetNativeControlReference("5483cdef-3049-4705-b597-28ae93bc7fdf"), EpiUltraCombo)
C# Code:
EpiUltraCombo eucSales = (EpiUltraCombo )csm.GetNativeControlReference("5483cdef-3049-4705-b597-28ae93bc7fdf");
Control.Combos is EpiCombo
?
---隱藏下拉菜單功能
private static void baseToolbarsManager_BeforeToolDropdown(object sender, Infragistics.Win.UltraWinToolbars.BeforeToolDropdownEventArgs args)
{
baseToolbarsManager.Tools["RemovePOLinkTool"].SharedProps.Visible = false;
baseToolbarsManager.Tools["IncomingICPOSugTool"].SharedProps.Visible = false;
baseToolbarsManager.Tools["SendICPOSugTool"].SharedProps.Visible = false;
}
---Set EpiUltraCombo Properties
this.epiUltraComboShipTo.ValueMember = "CustNum";
this.epiUltraComboShipTo.DataSource = dsCustomerAdapter;
this.epiUltraComboShipTo.DisplayMember = "Name";
string[] fields = new string[] {
"Name"};
this.epiUltraComboShipTo.SetColumnFilter(fields);
--fill epiUltraCombo
private void FillepiUltraComboFamily()
{
DataTable TB = new DataTable();
DataRow DR;
TB.Columns.Add("Family", typeof(String));
DR = TB.NewRow();
DR["Family"] = "FG";
TB.Rows.Add(DR);
DR = TB.NewRow();
DR["Family"] = "RM";
TB.Rows.Add(DR);
// Set EpiUltraCombo Properties
this.epiUltraComboFamily.ValueMember = "Family";
this.epiUltraComboFamily.DataSource = TB;
this.epiUltraComboFamily.DisplayMember = "Family";
string[] fields = new string[] {
"Family"};
this.epiUltraComboFamily.SetColumnFilter(fields);
}
