1.连接数据库
using System;
using System.Collections.Generic;
using System.Web;
using System.Data.OleDb; namespace myBPB
{
public class myDB
{
OleDbConnection conn = null;
public OleDbConnection getConn()
{
string sServer = "192.168.132.10";
string sDatabase = "myBPB";
string sUser = "sa";
string sPassword = "";
//Provider=SQLOLEDB; 指的是连接数据库所用的相关数据库驱动
//Data Source; 指的是服务器地址或服务器名称
//Persist Security Info; 指的是是否保存安全信息，其实可以简单的理解为"在数据库连接成功后是否保存密码信息"，True表示保存，False表示不保存
//Initial Catalog; 指的是要连接的数据库名称
//User ID; 登录数据库的名称
//Password; 登录数据库的密码
String sSQL = String.Format("Provider=SQLOLEDB;Data Source={0};" +"Persist Security Info=True;User ID={2};" +"Initial Catalog={1};Password={3};",sServer, sDatabase, sUser, sPassword);//数据库连接语句
try
{
conn = new OleDbConnection(sSQL);
conn.Open();
return conn;
}
catch (System.Exception ex)
{
return null;
}
}
}
}
连接数据库
2.填充ASPxGridView
public void BindGridView()
{
OleDbConnection conn = new myDB().getConn();
string str = "select * from 区域";
OleDbDataAdapter da = new OleDbDataAdapter(str, conn);
DataSet ds = new DataSet();
da.Fill(ds);
this.ASPxGridView1.DataSource = ds.Tables[].DefaultView;
this.ASPxGridView1.DataBind();
conn.Close();
}
填充ASPxGridView
3.布局
控件：ASPxSplitter（分离器）
作用：布局时多用于分割页面
属性：Orientation（方向）= Vertical（垂直）或 Herizontal（水平）
ASPxSplitter1.Panes[0].PaneStyle.Paddings.Padding = 0; //第一个面板的内边距为0
ASPxSplitter1.Panes[1].PaneStyle.Paddings.Padding = 0; //第二个面板的内边距为0
ASPxSplitter1.Panes[0].Size = 63; //第一个面板的高度(大小)为63
ASPxSplitter1.Panes[1].ScrollBars = ScrollBars.Auto; //自动出现滚动条
ASPxSplitter1.AllowResize = false; //不允许调整ASPxSplitter1
ASPxSplitter1.FullscreenMode = true; //全屏模式为true
控件：ASPxMenu1（菜单）
作用：制作菜单
属性：width（宽度）=100%
Items（菜单的选项）
ItemAutoWidth（菜单选项宽度自动调整）=True（真）或False（假）
AutoSeparators="RootOnly"（菜单选项之间用竖线隔开）
ClientInstanceName="ASPxMenu1"（控件的前端名称）
控件：表格
作用：排版
属性：Style—>表格—>table-layout=fixed（表格宽度为固定值）
控件：ASPxImage
作用：显示图标、图片
属性：ASPxImage1.ImageUrl = "~/Images/man.gif";
控件：ASPxGridView
作用：显示数据
属性：ASPxGridView1.Width = 2000;
ASPxGridView1.SettingsBehavior.AllowFocusedRow = true;//每行都可以选择
Columns（列）— Caption（显示名称）— FieldName（数据库连接字段）
AutoGenerateColumns="False"//数据源自动绑定为假
KeyFieldName="bh"//关键字为bh
ClientInstanceName="ASPxGridView1"（控件的前端名称）
前端运用：
1.在每行前面添加一个ASPxCheckBox
<dx:ASPxGridView ID="ASPxGridView1" runat="server">
<Columns> <dx:GridViewCommandColumn Caption="操作" ShowSelectCheckbox="true" VisibleIndex="" Width="20px">
<HeaderTemplate>
<dx:ASPxCheckBox ID="ASPxCheckBox1" runat="server" ToolTip="Select/Unselect all rows on the page"
ClientSideEvents-CheckedChanged="function(s, e) { ASPxGridView1.SelectAllRowsOnPage(s.GetChecked()); }" />
</HeaderTemplate>
</dx:GridViewCommandColumn> </Columns>
</dx:ASPxGridView>
自动添加ASPxCheck.xml
2.在第一列显示行号
<dx:ASPxGridView ID="ASPxGridView1" runat="server">
<Columns> <dx:GridViewDataTextColumn Caption="序号" FieldName="XH" UnboundType="Integer" VisibleIndex=""Width="36px">
<Settings AutoFilterCondition="Contains" />
<CellStyle HorizontalAlign="Center">
</CellStyle>
</dx:GridViewDataTextColumn> </Columns>
</dx:ASPxGridView>
自动添加行号.xml
protected void ASPxGridView1_CustomUnboundColumnData(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewColumnDataEventArgs e)
{
if (e.Column.FieldName == "XH" && e.IsGetData)
e.Value = (e.ListSourceRowIndex + ).ToString();
}
自动添加行号.后台
3.将Columns分组
<dx:GridViewBandColumn Caption="使用于">
<Columns>
<dx:GridViewDataTextColumn Caption="部门" FieldName="部门"
ShowInCustomizationForm="True" VisibleIndex="" Width="150px">
<Settings AutoFilterCondition="Contains" />
</dx:GridViewDataTextColumn>
<dx:GridViewDataTextColumn Caption="何工序或何设备" FieldName="何工序或何设备"
ShowInCustomizationForm="True" VisibleIndex="" Width="200px">
<Settings AutoFilterCondition="Contains" />
</dx:GridViewDataTextColumn>
</Columns>
</dx:GridViewBandColumn>
Columns.xml
4.ASPxComboBox配置数据源
<asp:SqlDataSource ID="SqlDataSource1_BuMen" runat="server"
ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
ProviderName="<%$ ConnectionStrings:ConnectionString.ProviderName %>"
SelectCommand="SELECT DISTINCT [部门名称], [部门编码] FROM [部门设置]"></asp:SqlDataSource>
数据源—部门.xml
<dx:ASPxComboBox ID="Com_BuMen" runat="server"
DataSourceID="SqlDataSource1_BuMen" ValueField="部门编码" DropDownStyle="DropDownList"
ValueType="System.String" TextFormatString="{1}" EnableCallbackMode="true"
IncrementalFilteringMode="Contains" TextField="部门编码"
ClientInstanceName="Com_BuMen" >
<Columns>
<dx:ListBoxColumn FieldName="部门编码" Width="45px" />
<dx:ListBoxColumn FieldName="部门名称" Width="100%" />
</Columns>
</dx:ASPxComboBox>
部门文本框.前台
5.增加
public void Add()
{
String str_add= "insert into 区域(区域号,区域,备注) values('" + QuYuHao + "','" + QuYu + "','" + BeiZhu + "')";
OleDbConnection conn = new myDB().getConn();
OleDbCommand com = new OleDbCommand(str_add, conn);
if(Convert.ToInt32(com.ExecuteNonQuery())>)
{
Page.ClientScript.RegisterClientScriptBlock(typeof(QuYuEdit), "CustomEdit", "alert('添加成功！！');", true);
}
else
{
Page.ClientScript.RegisterClientScriptBlock(typeof(QuYuEdit), "CustomEdit", "alert('添加失败！！');", true);
}
conn.Close();
}
增加.后台
6.删除
public void Del()
{
String str_Del = "delete from 区域 where bh=" + ;
OleDbConnection conn = new myDB().getConn();
OleDbCommand com = new OleDbCommand(str_Del, conn);
int counts = com.ExecuteNonQuery();
if (counts > )
{
Page.ClientScript.RegisterClientScriptBlock(typeof(WuLiaoBianMa), "CustomEdit", "alert('删除成功！');", true);
}
else
{
Page.ClientScript.RegisterClientScriptBlock(typeof(WuLiaoBianMa), "CustomEdit", "alert('删除失败！');", true);
}
conn.Close();
}

{
String str_Update = "update 区域 set 区域号='" + QuYuHao + "',区域='" + QuYu + "',备注='" + BeiZhu + "' where bh=" + Convert.ToInt32(ASPxHiddenField1.Get("SBH1"));
OleDbConnection conn = new myDB().getConn();
OleDbCommand com = new OleDbCommand(str_Del, conn);
int counts = com.ExecuteNonQuery();
if (counts > )
{
Page.ClientScript.RegisterClientScriptBlock(typeof(WuLiaoBianMa), "CustomEdit", "alert('修改成功！');", true);
}
else
{
Page.ClientScript.RegisterClientScriptBlock(typeof(WuLiaoBianMa), "CustomEdit", "alert('修改失败！');", true);
}
conn.Close();
}

8.查询
public String Old_Name()
{
OleDbConnection conn = new myDB().getConn();
string str = "select * from 物料编码 where bh='" + Convert.ToInt32(ASPxHiddenField1.Get("sBH")) + "'";
OleDbDataAdapter da = new OleDbDataAdapter(str, conn);
DataSet ds = new DataSet();
da.Fill(ds);
String m = ds.Tables[].Rows[]["物料编码"].ToString();
return m;
}
查询（DataAdapter、DataSet）.后台
public void Lei_Xing()
{
OleDbConnection conn = new myDB().getConn();
string str = "select * from 基础数据 where 目录='供应商类型'";
OleDbCommand com = new OleDbCommand(str, conn);
OleDbDataReader read = com.ExecuteReader();
while (read.Read())
{
Txt_LeiXing.Items.Add(read["内容"].ToString());
}
}
查询后台（DataReader）.后台
9.ASPxGridView中勾选ASPxCheckBox删除数据
List<object> keyValues = this.ASPxGridView1.GetSelectedFieldValues("bh"); //需要在ASPxGridView1的源设置 KeyFieldName="bh"
ASPxGridView1.Selection.UnselectAll(); //清空ASPxGridView中所有选择的语句。
int count = keyValues.Count;
if (str == "删除")
{
if (count <= )
{
Page.ClientScript.RegisterClientScriptBlock(typeof(WuLiaoBianMa), "CustomEdit", "alert('请选择要删除的数据！');", true);
return;
}
foreach (object key in keyValues)
{
do_del(key.ToString()); //删除
}
keyValues.Clear();
count = keyValues.Count;
BindGridView();
}
ASPxGridView中勾选ASPxCheckBox删除数据
10.ASPxGridView过滤
后台：ASPxGridView1.Settings.ShowFilterRow = true; 前台：<Settings AutoFilterCondition="Contains" />//ASPxGridView属性—>Columns—>要实现过滤的列—>Settings—>AutoFilterCondition="Contains"
11.ASPxGridViewExporter导出
if (Directory.Exists(Server.MapPath("tmp")) == false)
{
Directory.CreateDirectory(Server.MapPath("tmp"));
}
string path = Server.MapPath("~/tmp/");//获取完整路径
ASPxGridViewExporter1.FileName = "物料编码";
ASPxGridViewExporter1.PageHeader.Font.Size = ;
string message1 = @"物料编码";
ASPxGridViewExporter1.PageHeader.Center = message1;
this.ASPxGridViewExporter1.WriteXlsToResponse();
ASPxGridViewExporter导出.后台
12.ASPxHiddenField隐藏字段
设置前台名称：ClientInstanceName="hf1";
后台赋初值：ASPxHiddenField1.Add("SBH",0);
前台赋值：hf1.Set('sBH', ASPxGridView1.GetRowKey(ASPxGridView1.GetFocusedRowIndex())); //给隐藏字段赋值为ASPxGridView1当前被选中行的bh值
后台取值：ASPxHiddenField1.Get("sBH")；
前台取值：hf1.Get('sBH')
13.ASPxPopupControl自定义约会表单
设置前台名称：ClientInstanceName="ASPxPopupControl1"；
前台显示ASPxPopupControl自定义表单：ASPxPopupControl1.Show();
前台隐藏ASPxPopupControl自定义表单：ASPxPopupControl1.Hid();
14.ASPxUploadControl上传、导入实例（导入）
点击导入按钮，弹出下图的自定义约会表单，将选择的文件上传至固定的地址并导入ASPxGridView中
.前台弹出表单：ASPxPopupControl1.Show(); .上传文件到指定的地址：
String ExcelFileName = "";
protected voidASPxUploadControl1_FileUploadComplete(objectsender,DevExpress.Web.ASPxUploadControl.
FileUploadCompleteEventArgs e)
{
if (Directory.Exists(Server.MapPath("tmp")) == false)
{
Directory.CreateDirectory(Server.MapPath("tmp"));
}
if (e.IsValid)
{
ASPxUploadControl1.PostedFile.SaveAs(Server.MapPath("~/tmp/")+ ASPxUploadControl1.PostedFile.FileName);
ExcelFileName = ASPxUploadControl1.PostedFile.FileName;
}
} .导入ASPxGridView：
#region 从Table导出数据DaoRu()
public void DaoRu(ASPxGridView ASPxGridView1,String ExcelFileName)
{
try //步骤一：先将用户选择的EXCEL文件上传至服务器端。
{
if (Directory.Exists(Server.MapPath("tmp")) == false)
{
Directory.CreateDirectory(Server.MapPath("tmp"));
}
string path = Server.MapPath("~/tmp/") + ExcelFileName;//获取完整路径
GetOneSheet("Sheet", path, ASPxGridView1); }
catch
{
throw;
}
} // 步骤二：将上传的文件导入至DataSet
public static void GetOneSheet(string sheetname, string Path, ASPxGridView ASPxGridView1)
{
try
{
string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + Path + ";Extended Properties=Excel 8.0;";
OleDbConnection con = new OleDbConnection(connString); //连接excel表
con.Open();
String strOutPutExcel = "select * from [" + sheetname + "$]";
OleDbDataAdapter ad = new OleDbDataAdapter(strOutPutExcel, con);
DataSet table = table = new DataSet();
ad.Fill(table,"table1"); //填充dataset
int count = table.Tables[].Rows.Count;
OleDbConnection conn = new myDB().getConn();
OleDbCommand com = null;
for (int i = ; i < count; i++)
{ String QuYuHao = table.Tables[].Rows[i][].ToString().Trim();
String LeiBeiHao = table.Tables[].Rows[i][].ToString().Trim();
String str_insert = "INSERT INTO [物料编码] ( [区域号], [类别号]) VALUES (?, ?)"; OleDbParameter op1 = new OleDbParameter();
OleDbParameter op2 = new OleDbParameter(); op1.OleDbType = OleDbType.VarChar;
op2.OleDbType = OleDbType.VarChar;
op1.Value = QuYuHao.ToString();
op2.Value = LeiBeiHao.ToString();
com = new OleDbCommand(str_insert,conn);
com.Parameters.Add(op1);
com.Parameters.Add(op2);
try
{
com.ExecuteNonQuery();
}
catch
{
//Debug.WriteLine();
} }
con.Close();
}
catch
{
throw;
}
}
#endregion .确定按钮单击事件中调用DaoRu()：
DaoRu(ASPxGridView1, ExcelFileName);
BindGridView(); //重新填充ASPxGridView
代码实现
15.根据ASPxGridView值得变化，前端给控件赋值实例（修改）
.ClientInstanceName="ASPxGridView1" //要赋值的前端控件也需设置前端名称
.判断是否选择了"修改"
if (str == "修改")
{
Session.Add("Add_Or_Update", );
Response.Redirect("~/WuLiaoBianMaEdit.aspx"); //转到下图的修改页面
} ."修改"页面加载：
if (!IsPostBack)
{
if (Convert.ToInt32(Session["Add_Or_Update"]) == )
{
ASPxImage1.ImageUrl = "~/Images/m5.gif";
ASPxRoundPanel1.HeaderText = "修改";
ASPxHiddenField1.Add("sBH2", );
ASPxHiddenField1.Add("sBH", );
}
} .ASPxGridView单击事件：
<ClientSideEvents FocusedRowChanged="function(s, e) { OnGridFocusedRowChanged(); }" />
<ClientSideEvents FocusedRowChanged="function(s, e) { OnGridFocusedRowChanged(); }"></ClientSideEvents>
<%--ASPxGridView的单击事件--%> .Javascript实现ASPxGridView单击事件：
<script language="javascript" type="text/javascript">
function OnGridFocusedRowChanged()
{
ASPxGridView1.GetRowValues(ASPxGridView1.GetFocusedRowIndex(), '区域号;类别号', OnGetRowValues); //前端访问控件
}
function OnGetRowValues(values)
{
hf1.Set('sBH', ASPxGridView1.GetRowKey(ASPxGridView1.GetFocusedRowIndex())); //给隐藏字段赋值
if (hf1.Get('sBH2') == )
{
Com_QuYuHao.SetText(values[]);
Com_LeiBieHao.SetText(values[]);
}
}
</script>
代码实现
16.选择"区域号","类别号"后，点击"已用流水号"按钮，从数据库中读取数据加载到表单中，并弹出表单（防止刷屏问题）
.ClientInstanceName="grid2"
.写一个自定义函数，填充表单中的ASPxGridView：
public void LiuShuiHao(String QuYuHao,String LeiBieHao)
{
String str_LiuShuiHao = "";
if (QuYuHao != "" && LeiBieHao != "")
{
str_LiuShuiHao = "select * from 物料编码 where 区域号='" + QuYuHao + "' and 类别号='" + LeiBieHao + "'";
}
else if (QuYuHao != "")
{
str_LiuShuiHao = "select * from 物料编码 where 区域号='" + QuYuHao + "'";
}
else if (LeiBieHao != "")
{
str_LiuShuiHao = "select * from 物料编码 where 类别号='" + LeiBieHao + "'";
}
if(str_LiuShuiHao!="")
{
OleDbConnection conn = new myDB().getConn();
OleDbDataAdapter da = new OleDbDataAdapter(str_LiuShuiHao, conn);
DataSet ds = new DataSet();
da.Fill(ds);
this.ASPxGridView2.DataSource = ds.Tables[].DefaultView;
this.ASPxGridView2.DataBind();
conn.Close();
}
} .在页面的load中调用该方法：
if (Com_QuYuHao.Text != "" || Com_LeiBieHao.Text != "")
{
LiuShuiHao(Com_QuYuHao.Text, Com_LeiBieHao.Text);
} .按钮的前端Click事件：
ASPxPopupControl1.Show();
grid2.Refresh();
e.processOnServer = false; 读取数据库防止—刷屏
