C# DevExpress下GridControl控件的增删查改

DevExpress的GridControl控件可以从任何数据源绑定数据并进行增删查改等操作，和VS自带的dataGridView控件对比，GridControl控件可以实现更多自定义的功能，界面UI也更精美，今天我和大家分享一个Demo演示GridControl控件的增删查改操作！

首先，主界面由一个GridControl控件构成，可执行数据的增、删、查、改和导出操作，如图1所示：

图1-主界面（点击图片可放大）

实战演示：

1.主界面添加一个GridControl控件和一个Button，如图2所示：

图2-操作步骤1（点击图片可放大）

2.将GridControl控件的UseEmbeddedNavigator 属性设置为True，如图3所示：

图3-操作步骤2（点击图片可放大）

3.项目中添加System.ComponentModel.DataAnnotations引用，用于验证字段数据正确性，如图4所示：

图4-操作步骤3（点击图片可放大）

4.在初始化方法中添加gridControl控件的标题、顶部添加项、允许编辑和删除事件等，代码如下：

public Form1()

{

InitializeComponent();

 

//gridView1标题

gridView1.GroupPanelText = "深圳精品4S旗舰店订单管理：";

 

//gridView1顶部显示添加行

gridView1.OptionsView.NewItemRowPosition = NewItemRowPosition.Top;

 

//gridView1允许编辑

gridView1.OptionsBehavior.Editable = true;

 

//gridView1选中行后按快捷键 “Ctrl+Del” 删除

gridControl1.ProcessGridKey += (s, e) =>

{

if (e.KeyCode == Keys.Delete && e.Modifiers == Keys.Control)

{

if (XtraMessageBox.Show("是否删除选中行?", "删除行对话框", MessageBoxButtons.YesNo) !=

DialogResult.Yes)

return;

GridControl grid = s as GridControl;

GridView view = grid.FocusedView as GridView;

view.DeleteSelectedRows();

}

};

}

5.定义一个类用来进行字段属性设置并通知客户端，代码如下：

/// <summary>

/// 字段属性设置并验证字段属性数据的正确性，属性变更后向客户端发出属性值已更改的通知。

/// </summary>

public class Record : INotifyPropertyChanged

{

public Record()

{

}

int id;

[DisplayName("订单号")]

public int ID

{

get { return id; }

set

{

if (id != value)

{

id = value;

OnPropertyChanged();

}

}

}

 

string text;

[DisplayName("品牌")]

public string Brand

{

get { return text; }

set

{

if (text != value)

{

if (string.IsNullOrEmpty(value))

throw new Exception();

text = value;

OnPropertyChanged();

}

}

}

Nullable<decimal> val;

[DataType(DataType.Currency)]

[DisplayName("售价")]

public Nullable<decimal> Value

{

get { return val; }

set

{

if (val != value)

{

val = value;

OnPropertyChanged();

}

}

}

DateTime dt;

[DisplayName("交期")]

public DateTime RequiredDate

{

get { return dt; }

set

{

if (dt != value)

{

dt = value;

OnPropertyChanged();

}

}

}

bool state;

[DisplayName("完成")]

public bool Processed

{

get { return state; }

set

{

if (state != value)

{

state = value;

OnPropertyChanged();

}

}

}

 

public event PropertyChangedEventHandler PropertyChanged;

protected void OnPropertyChanged([CallerMemberName] string propertyName = "")

{

if (PropertyChanged != null)

PropertyChanged(this, new PropertyChangedEventArgs(propertyName));

}

}

6.定义一个数据随机生成方法并传值到字段中，代码如下：

/// <summary>

/// 生成随机字段数据

/// </summary>

public class DataHelper

{

public static string[] brands = new string[] { "奔驰", "宝马", "奥迪", "大众",

"马自达", "雷克萨斯", "红旗" ,"路虎","丰田","本田","现代"};

 

public static BindingList<Record> GetData(int count)

{

BindingList<Record> records = new BindingList<Record>();

Random rnd = new Random();

for (int i = 0; i < count; i++)

{

int n = rnd.Next(10);

records.Add(new Record()

{

ID = i + 2020000,

Brand = brands[i % brands.Length],

RequiredDate = DateTime.Today.AddDays(n + 30),

Value = i % 2 == 0 ? (i + 1) * 123456 : i * 12345,

Processed = i % 2 == 0,

});

};

return records;

}

}

7.定义一个方法利用XtraPrinting导出GridControl中的信息并保存为Excel，代码如下：

/// <summary>

/// 导出dataGrid为Excle

/// </summary>

/// <param name="sender"></param>

/// <param name="e"></param>

private void Btn_Output_Click(object sender, EventArgs e)

{

SaveFileDialog fileDialog = new SaveFileDialog();

fileDialog.Title = "导出Excel";

fileDialog.Filter = "Excel文件(*.xls)|*.xls";

DialogResult dialogResult = fileDialog.ShowDialog(this);

if (dialogResult == DialogResult.OK)

{

DevExpress.XtraPrinting.XlsExportOptions options = new

DevExpress.XtraPrinting.XlsExportOptions();

gridControl1.ExportToXls(fileDialog.FileName);

DevExpress.XtraEditors.XtraMessageBox.Show("保存成功！", "提示",

MessageBoxButtons.OK, MessageBoxIcon.Information);

}

}

8.在Form_Load函数中给gridControl控件绑定数据并修改单元格外观，实现启动时自动加载数据，代码如下：

private void Form1_Load(object sender, EventArgs e)

{

//dataGrid自动在数据源中找到公共字段并创建列。

gridControl1.DataSource = DataHelper.GetData(10);

 

//创建一个ComboBox编辑器，在“品牌”列中显示可用的品牌。

RepositoryItemComboBox riComboBox = new RepositoryItemComboBox();

riComboBox.Items.AddRange(DataHelper.brands);

gridControl1.RepositoryItems.Add(riComboBox);

gridView1.Columns["Brand"].ColumnEdit = riComboBox;

 

//设置订单号列的外观颜色

GridColumn colID = gridView1.Columns["ID"];

colID.AppearanceCell.BackColor2 = Color.DarkGreen;

colID.AppearanceCell.BackColor = Color.LightGreen;

colID.AppearanceCell.ForeColor = Color.White;

 

//设置品牌列的外观颜色

GridColumn colCompanyName = gridView1.Columns["Brand"];

colCompanyName.AppearanceCell.BackColor = Color.DarkKhaki;

colCompanyName.AppearanceCell.ForeColor = Color.Black;

 

//设置交期列的外观颜色

GridColumn colRequiredDate = gridView1.Columns["RequiredDate"];

colRequiredDate.AppearanceCell.ForeColor = Color.Red;

}
