DEV GridControl一些屬性配置--40開始爲原創

1、如何解決單擊記錄整行選中的問題

View->OptionsBehavior->EditorShowMode 設置爲：Click

2、如何新增一條記錄

(1)、gridView.AddNewRow()

(2)、實現 gridView_InitNewRow 事件

3、如何解決 GridControl 記錄能獲取而沒有顯示出來的問題

gridView.populateColumns();

4、如何讓行只能選擇而不能編輯（或編輯某一單元格）

(1)、View->OptionsBehavior->EditorShowMode 設置爲：Click

(2)、View->OptionsBehavior->Editable 設置爲：false

5、如何禁用 GridControl 中單擊列彈出右鍵菜單

設置 Run Design->OptionsMenu->EnableColumnMenu 設置爲：false

6、如何隱藏 GridControl 的 GroupPanel 表頭

設置 Run Design->OptionsView->ShowGroupPanel 設置爲：false

7、如何禁用 GridControl 中列頭的過濾器過濾器如下圖所示：
設置 Run Design->OptionsCustomization->AllowFilter 設置爲：false

8、如何在查詢得到 0 條記錄時顯示自定義的字符提示/顯示如圖所示：

方法如下：

//When no Records Are Being Displayed

private void gridView1_CustomDrawEmptyForeground(object sender, CustomDrawEventArgs e)

{

//方法一（此方法爲GridView設置了數據源綁定時，可用）

ColumnView columnView = sender as ColumnView;

BindingSource bindingSource = this.gridView1.DataSource as BindingSource;

if(bindingSource.Count == 0)

{

string str = "沒有查詢到你所想要的數據!";

Font f = new Font("宋體", 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Top + 5, e.Bounds.Left + 5, e.Bounds.Right - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); }

//方法二（此方法爲GridView沒有設置數據源綁定時，使用，一般使用此種方法）

if (this._flag)

{ if (this.gridView1.RowCount == 0)

{ string str = "沒有查詢到你所想要的數據!"; Font f = new Font("宋體", 10, FontStyle.Bold);

Rectangle r = new Rectangle(e.Bounds.Left + 5, e.Bounds.Top + 5, e.Bounds.Width - 5, e.Bounds.Height - 5);

e.Graphics.DrawString(str, f, Brushes.Black, r); } } }

9、如何顯示水平滾動條？或

設置 this.gridView.OptionsView.ColumnAutoWidth = false;

.....列表寬度自適應內容

gridview1.BestFitColumns();

10、如何定位到第一條數據/記錄？

設置 this.gridView.MoveFirst()

11、如何定位到下一條數據/記錄？
設置 this.gridView.MoveNext()

12、如何定位到最後一條數據/記錄？

設置 this.gridView.MoveLast()

13、設置成一次選擇一行，並且不能被編輯

this.gridView1.FocusRectStyle = DevExpress.XtraGrid.Views.Grid.DrawFocusRectStyle.RowFocus;

this.gridView1.OptionsBehavior.Editable = false;

this.gridView1.OptionsSelection.EnableAppearanceFocusedCell = false;

14、如何顯示行號？
private void gvPayList_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
        {
            e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
            if (e.Info.IsRowIndicator)
            {
                if (e.RowHandle >= 0)
                {
                    e.Info.DisplayText = (e.RowHandle + 1).ToString();
                }
                else if (e.RowHandle < 0 && e.RowHandle > -1000)
                {
                    e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
                    e.Info.DisplayText = "G" + e.RowHandle.ToString();
                }
            }
        }

15、如何讓各列頭禁止移動？

設置 gridView1.OptionsCustomization.AllowColumnMoving = false;

16、如何讓各列頭禁止排序？

設置 gridView1.OptionsCustomization.AllowSort = false;

17、如何禁止各列頭改變列寬？

設置 gridView1.OptionsCustomization.AllowColumnResizing = false;

18.拖動滾動條時固定某一列

設置Columns，選擇要固定的列。設置Fixed屬性，可以選擇：固定在左邊、固定在右邊、不固定。

19.獲取選定行,指定列單元格的內容

return gridView1.GetRowCellValue(pRows[0], ColumName).ToString ();

20.分組顯示

OptionsView>OptionsBehavior>AutoExpandAllGroups = True
選擇要分組的列，將GroupIndex屬性設置爲0

21.格式化數據

       private void gvList_ValidatingEditor(object sender, DevExpress.XtraEditors.Controls.BaseContainerValidateEditorEventArgs e)
        {
            if (this.gvList.FocusedColumn.FieldName == "passQty")
            {
                string passQty = e.Value.ToString().Trim();
                int receiveQty = orderDetailList[this.gvList.FocusedRowHandle].qty;
                if (!JXType.IsIntBigThanZero(passQty))
                {
                    e.Valid = false;
                    e.ErrorText = "合格數量必須爲大於等於0小於等於接貨數量的整數！";
                }
                else
                {
                    if (int.Parse(passQty) > receiveQty)
                    {
                        e.Valid = false;
                        e.ErrorText = "合格數量必須爲大於0小於等於接貨數量的整數！";
                    }
                }
            }

}

22.合併表頭

///初始化表格

using DevExpress.XtraGrid.Columns;
using DevExpress.XtraGrid.Views.Base;
using DevExpress.XtraGrid.Views.BandedGrid;
using DevExpress.XtraEditors.Repository;
private void InitGrid()
{
// advBandedGridView1是表格上的默認視圖，注意這裏聲明的是：BandedGridView
BandedGridView view = advBandedGridView1 as BandedGridView;
view.BeginUpdate(); //開始視圖的編輯，防止觸發其他事件
view.BeginDataUpdate(); //開始數據的編輯
view.Bands.Clear();

view.OptionsView.ShowColumnHeaders = false; //因爲有Band列了，所以把ColumnHeader隱藏
//添加列標題
   //添加列標題
            GridBand bandID = view.Bands.AddBand("ID");
            bandID.Visible = false; //隱藏ID列
            GridBand bandName = view.Bands.AddBand("姓名");
            GridBand bandSex = view.Bands.AddBand("性別");
            GridBand bandBirth = view.Bands.AddBand("出生日期");
            GridBand bandScore = view.Bands.AddBand("分數");
            GridBand bandMath = bandScore.Children.AddBand("數學");
            GridBand bandChinese = bandScore.Children.AddBand("語文");
            GridBand bandEnglish = bandScore.Children.AddBand("英語");
            GridBand bandSubTotal = bandScore.Children.AddBand("小計");
            GridBand bandRemark = view.Bands.AddBand("備註");

bandFile.AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;//這是合併表頭居中顯示
view.EndDataUpdate();//結束數據的編輯
view.EndUpdate(); //結束視圖的編輯
}

點擊打開鏈接

23. //動態添加列
DevExpress.XtraGrid.Columns.GridColumn Col1 = new DevExpress.XtraGrid.Columns.GridColumn();
Col1.FieldName = "name";
Col1.Caption = "名字";
Col1.Visible = false;
Col1.VisibleIndex = gvCountry.Columns.Count;
gvCountry.Columns.Add(Col1);

24。設置自動增加的行號

private void gridview_CustomDrawRowIndicator(object sender, DevExpress.XtraGrid.Views.Grid.RowIndicatorCustomDrawEventArgs e)
{

e.Appearance.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Far;
if (e.Info.IsRowIndicator)
{
if (e.RowHandle >= 0)
{
e.Info.DisplayText = (e.RowHandle + 1).ToString();
}
else if (e.RowHandle < 0 && e.RowHandle > -1000)
{
e.Info.Appearance.BackColor = System.Drawing.Color.AntiqueWhite;
e.Info.DisplayText = "G" + e.RowHandle.ToString();
}
}

｝

25.特效：gridcontrol中有5種view 型式，普通的是gridview，然後分別爲cardview、BandedView、Advanced BandedView、LayoutView；共5種。

1）、view組中把OptionView下的viewmode 設置成“Carousel”就達到這種“旋轉木馬”式的gridcontrol view 特效了
2）、layoutView1.OptionsCarouselMode.PitchAngle 這個屬性決定“旋轉木馬”的pitch angle 螺距角; 螺旋角; 螺旋升角; 俯仰角; 傾角; 節錐半角
3）、Roll Angle 屬性決定着傾側角度
4）、指定數據源，顯示數據：
//顯示數據
        private void showData(List<Employee > list)
        {
            DataTable dt = new DataTable("OneEmployee");
            dt.Columns.Add("Caption", System.Type.GetType("System.String"));
            dt.Columns.Add("Department", System.Type.GetType("System.String"));
            dt.Columns.Add("PhotoName", System.Type.GetType("System.Byte[]"));

            for (int i = 0; i < list.Count; i++)
            {
                DataRow dr = dt.NewRow();
                dr["Caption"] = list[i].Name;
                dr["Department"] = list[i].Department;
                string imagePath = @"D:\C#\photos\" + list[i].PhotoPath;
                dr["PhotoName"] = getImageByte(imagePath);
                dt.Rows.Add(dr);
            }
            gridControl1.DataSource = dt;
        }

        //返回圖片的字節流byte[]
        private byte[] getImageByte(string imagePath)
        {
            FileStream files = new FileStream(imagePath, FileMode.Open);
            byte[] imgByte = new byte [files.Length ];
            files.Read(imgByte, 0, imgByte.Length);
            files.Close();
            return imgByte;
        }

26.檢查數據的有效性

在gridview的ValidateRow事件中加入檢查代碼：
#region 檢查數據
private void gridView1_ValidateRow(object sender, ValidateRowEventArgs e)
{
GridView view = sender as GridView;
view.ClearColumnErrors();

if (view.GetRowCellValue(e.RowHandle, "ReceiveDate") == DBNull.Value)
{
e.Valid = false;
view.SetColumnError(view.Columns["ReceiveDate"], "必須指定日期");
}

}

27.設某一列文字和標題局中顯示
   gridView1.Columns[0].AppearanceHeader.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;
   gridView1.Columns[0].AppearanceCell.TextOptions.HAlignment = DevExpress.Utils.HorzAlignment.Center;

28.列表過濾條件多選

列名.OptionsFilter.FilterPopupMode= DevExpress.XtraGrid.Columns.FilterPopupMode.CheckedList

29.隔行換色的方法

this.gridView1.Appearance.OddRow.BackColor = Color.White; // 設置奇數行顏色 // 默認也是白色可以省略
this.gridView1.OptionsView.EnableAppearanceOddRow = true; // 使能 // 和和上面綁定同時使用有效
this.gridView1.Appearance.EvenRow.BackColor = Color.WhiteSmoke; // 設置偶數行顏色
this.gridView1.OptionsView.EnableAppearanceEvenRow = true; // 使能 // 和和上面綁定同時使用有效

30.合併單元格

設置Gridview的AllowCellMerge屬性爲ture,然後設置要合併列的AllowCellMerge爲True，這樣某列相同行內容就會合並了

31.如果要改變單元格樣式，如字體顏色，背景什麼，像html頁面樣式。。。。

將ColumnEdit改成repositoryItemRichTextEdit然後ColumnEdit=>DocumentFormat改成html，這樣單元格就可以顯示跟html一樣的樣式，很方便

32.動態綁定列的下拉框值

private DevExpress.XtraEditors.Repository.RepositoryItemImageComboBox repositoryItemImageComboBox_Test = new DevExpress.XtraEditors.Repository.RepositoryItemImageComboBox();

private void gvList_CustomRowCellEdit(object sender, DevExpress.XtraGrid.Views.Grid.CustomRowCellEditEventArgs e)
{
string fieldName = e.Column.FieldName;
DataRow selectRow = gvList.GetDataRow(e.RowHandle);
if (fieldName == "test")
{
if (Convert.ToInt32(selectRow["aaa"]) == 0)
{

repositoryItemImageComboBox_Test.Items.AddRange(new DevExpress.XtraEditors.Controls.ImageComboBoxItem[] {
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("A", "A", -1),
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("B", "B", -1),
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("C", "C", -1),
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("D", "D", -1)});
e.RepositoryItem = repositoryItemImageComboBox_Test;
}
else
{

repositoryItemImageComboBox_Test.Items.AddRange(new DevExpress.XtraEditors.Controls.ImageComboBoxItem[] {
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("A", "A", -1),
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("B", "B", -1),
new DevExpress.XtraEditors.Controls.ImageComboBoxItem("C", "C", -1),
e.RepositoryItem = repositoryItemImageComboBox_Test;
}
}
}
