c#winFormDotNetBar控件之SuperGridControl

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

1.添加表头

            sgc.PrimaryGrid.SelectionGranularity = SelectionGranularity.Row;//点击选中一行
            DevComponents.DotNetBar.SuperGrid.GridColumn gc = null;

            gc = new DevComponents.DotNetBar.SuperGrid.GridColumn("ID");
            sgc.PrimaryGrid.Columns.Add(gc);
            gc = new DevComponents.DotNetBar.SuperGrid.GridColumn("类型编码");
            sgc.PrimaryGrid.Columns.Add(gc);

2.添加数据 加一行

sgc.PrimaryGrid.Rows.Add(new GridRow(new object[] { "a", "b" }));//也就是加一个GrindRow对像 

 

3.设点击选中一行后 取第一行第一列的值

SelectedElementCollection col = sgc.PrimaryGrid.GetSelectedRows();//选中的行集合

if (col.Count > 0)
    {
      GridRow gr = (col[0] as GridRow);//把第一行转为GridRow 
      fac.ID = int.Parse(gr.Cells[0].Value.ToString());//取第一列的Value转一下

      //等效于int id= int.Parse((sgc.PrimaryGrid.GetSelectedRows()[0] as GridRow).Cells[0].Value.ToString());
     }

 4.增加一个下拉框

 4.1

using DevComponents.DotNetBar.SuperGrid;
using System;
using System.Windows.Forms;

namespace TestForm
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Load += Form1_Load;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            GridColumn col = new GridColumn("这是一个下拉框");
            col.HeaderText = "这是一个下拉框";
            col.Name = "这是一个下拉框";

            col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells;
            col.EditorType = typeof(DefineGridCB);
            col.EditorParams = new object[] { new object[] { "第一个", "第二个" } };


            superGridControl1.PrimaryGrid.Columns.Add(col);
        }

        //自定义控件
        public class DefineGridCB : GridComboBoxExEditControl
        {
            public DefineGridCB(object source)
            {
                DataSource = source;
            }
        }

        //增加一行
        private void buttonItem1_Click(object sender, EventArgs e)
        {
            superGridControl1.PrimaryGrid.NewRow(true);
        }
    }
}
View Code

  4.2 方法二 上边不传值 直接给一个无参构造方法

  public class ThisGridComboBoxControl : GridComboBoxExEditControl
        {
            public ThisGridComboBoxControl()
            {

                CustomList cl = new CustomList("BSC201Compare"); 
                DataTable dt = cl.GetList();//这里我是执行了一个sql查询 有符号和名称两个列 反回一个dataTable

                DataSource = dt;
                DisplayMember = "名称";
                ValueMember = "符号";

                DropDownStyle = ComboBoxStyle.DropDownList;
                DropDownColumns = "名称|符号";
                MaxDropDownItems = 8;

            }
        }

4.2效果 

 

5.增加一个按钮

using DevComponents.DotNetBar.SuperGrid;
using System;
using System.Windows.Forms;
using DevComponents.DotNetBar.SuperGrid.Style;

namespace TestForm
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
            this.Load += Form1_Load;
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            GridColumn col = new GridColumn("这是一个下拉框");
            col.HeaderText = "这是一个下拉框";
            col.Name = "这是一个下拉框";

            col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells;
            col.EditorType = typeof(DefineGridCB);
            col.EditorParams = new object[] { new object[] { "第一个", "第二个" } };
            superGridControl1.PrimaryGrid.Columns.Add(col);

            col = new GridColumn("这是一个按钮");
            col.AutoSizeMode = ColumnAutoSizeMode.DisplayedCells;
            col.EditorType = typeof(DefineGridButtonX);
            superGridControl1.PrimaryGrid.Columns.Add(col);
        }

        /// <summary>
        /// 自己定义按钮
        /// </summary>
        public class DefineGridButtonX : GridButtonXEditControl
        {
            public DefineGridButtonX()
            {
                this.Click += DefineGridButtonX_Click;
            }

            private void DefineGridButtonX_Click(object sender, EventArgs e)
            {
                MessageBox.Show("1");
            }

            /// <summary>
            /// 控件属性
            /// </summary>
            /// <param name="cell"></param>
            /// <param name="style"></param>
            public override void InitializeContext(GridCell cell, CellVisualStyle style)
            {
                base.InitializeContext(cell, style);
                this.Text = "这是一个按钮";
            }

        }



        //自定义下拉控件
        public class DefineGridCB : GridComboBoxExEditControl
        {
            public DefineGridCB(object source)
            {
                DataSource = source;
            }
        }

        //增加一行
        private void buttonItem1_Click(object sender, EventArgs e)
        {
            superGridControl1.PrimaryGrid.NewRow(true);
        }
    }
}
View Code

改变按钮颜色-依照别的列改变 在class的初始化中做如下操作

 public override void InitializeContext(GridCell cell, CellVisualStyle style)
            {
                base.InitializeContext(cell, style);
          BackColor = Color.Transparent;//这个必须加上 不然也没有效果
if ((EditorCell.GridRow["这是一个下拉框"].Value ?? "").ToString() != "") { unchecked { ForeColor = Color.FromArgb(255, 135, 206, 235); BackColor = Color.FromArgb(255, 135, 206, 235); } ColorTable = eButtonColor.Blue; } }

 

 

4~5效果

   

5.superGridControl一列变化 另一列自动加载对应的数据 判断一下值变货的单元格(后来看了看还是用cellClick会更好一些

 private void SuperGridControl1_CellValueChanged(object sender, GridCellValueChangedEventArgs e)
        {
            if (e.GridCell.GridColumn.Name == "下拉列")
            {
                superGridControl1.PrimaryGrid.Columns["下拉变动列"].EditorParams = new object[] { new object[] { "wf","HH"} };
            }
        }

 6.自动行高

SPG.PrimaryGrid.DefaultRowHeight = 0;

 7.去掉列头行头

            sgcCondition.SPG.PrimaryGrid.ShowColumnHeader = false;
           // sgcCondition.SPG.PrimaryGrid.ColumnHeader.Visible = false;//效果ms和上边一个样。。。
            sgcCondition.SPG.PrimaryGrid.ShowRowHeaders = false;

 8.选中行 默认选中首行

SPG.PrimaryGrid.SelectionGranularity = SelectionGranularity.Row;
SPG.PrimaryGrid.InitialSelection = RelativeSelection.Row;

 9.增加一行

 spgDetail.PrimaryGrid.NewRow(true);

10.删除选中行

SelectedElementCollection lstGR = spgDetail.PrimaryGrid.GetSelectedRows();
            if (lstGR != null)
                if (lstGR.Count > 0)
                {
                    foreach (GridRow gr in lstGR)
                    {

                        spgDetail.PrimaryGrid.Rows.Remove(gr);
                    }
                }

11.显示行号 且从1开始

SPG.PrimaryGrid.ShowRowGridIndex = true;
SPG.PrimaryGrid.RowHeaderIndexOffset=1;

 12.交换两行数据 实现上移下移

public static object[] GetRowValues(GridContainer gcRow)
        {
            object[] obj = new object[(gcRow as GridRow).Cells.Count];

            for (int i = 0; i < (gcRow as GridRow).Cells.Count; i++)
            {
                obj[i] = (gcRow as GridRow)[i].Value;
            }
            return obj;
        }
        /// <summary>
        /// 上、下移动表格行 
        /// </summary>
        /// <param name="spg"></param>
        /// <param name="gr"></param>
        /// <param name="isUp"></param>
        public static bool MoveSPGRow(SuperGridControl spg, bool isUp = true)
        {

            var atRow = spg.PrimaryGrid.ActiveRow;

            if (atRow == null)
            {
                PublicProperties.ShowInformation("请先选中要移动的行", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下
                return false;
            }
            object[] objRow = GetRowValues(atRow);

            if (isUp)
            {
                if (atRow.RowIndex == 0)
                {
                    PublicProperties.ShowInformation("已经是第一行了,无法再向上移动", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下
                    return false;
                }

                var atTop = spg.PrimaryGrid.Rows[atRow.RowIndex - 1];
                object[] objTop = GetRowValues(atTop as GridRow);
                spg.PrimaryGrid.Rows[atRow.Index - 1] = new GridRow(objRow);
                spg.PrimaryGrid.Rows[atRow.Index] = new GridRow(objTop);
                spg.PrimaryGrid.SetActiveRow(spg.PrimaryGrid.Rows[atRow.Index - 1] as GridRow);
                spg.PrimaryGrid.SetSelected(spg.PrimaryGrid.Rows[atRow.Index] as GridRow, false);
            }
            else
            {
                if (atRow.RowIndex == spg.PrimaryGrid.Rows.Count - 1)
                {
                    PublicProperties.ShowInformation("已经是最后一行了,无法再向下移动", AlertImage.Alert, 2000);//这里是个吐司函数就是提示一下
                    return false;
                }

                var atBottum = spg.PrimaryGrid.Rows[atRow.RowIndex + 1];
                object[] objBottum = GetRowValues(atBottum as GridRow);
                spg.PrimaryGrid.Rows[atRow.Index + 1] = new GridRow(objRow);
                spg.PrimaryGrid.Rows[atRow.Index] = new GridRow(objBottum);
                spg.PrimaryGrid.SetActiveRow(spg.PrimaryGrid.Rows[atRow.Index + 1] as GridRow);
                spg.PrimaryGrid.SetSelected(spg.PrimaryGrid.Rows[atRow.Index] as GridRow, false);
            }

            return true;
        }
    }
View Code

 13.编辑superGridCell时 焦点没离开cell 点不失焦点的控件 如bar的buttonItem 那么cell里的值不会变,这里可用SetActive()函数 使焦点离开cell

SPG.PrimaryGrid.SetActive(false)

 14.选中行自动行高

        /// <summary>
        /// 只对选中行自动行高
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void SPG_RowActivated(object sender, GridRowActivatedEventArgs e)
        {

            GridRow newrow = e.NewActiveRow == null ? new GridRow() : (e.NewActiveRow as GridRow);
            GridRow oldrow = e.OldActiveRow == null ? new GridRow() : e.OldActiveRow as GridRow;
            newrow.RowHeight = 0;
            if (newrow != oldrow)
            {
                oldrow.RowHeight = 21;//原始宽度
            }

        }

 15.superGrid 实现选中区域上下填充

/// <summary>
        /// 实现superGridControl选中区上下填充
        /// </summary>
        /// <param name="isDown">true 向下 false 向上</param>
        /// <param name="isFolowCursor">true激活行跟随 false 不跟随</param>
        private static void FillCells(SuperGridControl SPG, bool isDown = true, bool isFolowCursor = true)
        {
            //var cellSel = spgData.SPG.GetSelectedCells();
            //if (cellSel != null)
            //{
            //}
            var cellSel = SPG.GetSelectedCells();

            if (cellSel == null)
            {
                return;
            }

            int iFirst = (cellSel.First() as GridCell).RowIndex;
            int iEnd = (cellSel.Last() as GridCell).RowIndex;

            GridRow grFirst = SPG.PrimaryGrid.Rows[iFirst] as GridRow;
            GridRow grEnd = SPG.PrimaryGrid.Rows[iEnd] as GridRow;

            for (int j = iFirst; j <= iEnd; j++)
            {
                GridRow gr = SPG.PrimaryGrid.Rows[j] as GridRow;

                GridRow grTmp = null;
                if (isDown)
                    grTmp = grFirst;
                else
                    grTmp = grEnd;


                for (int i = 0; i < SPG.PrimaryGrid.Columns.Count; i++)
                {
                    if (gr[i].IsSelected && gr[i].AllowEdit == true)
                    {
                        gr[i].Value = grTmp[i].Value;
                    }
                }

                if (isFolowCursor)
                    gr.SetActive();
            }

            if (isFolowCursor)
                grFirst.SetActive();
        }

 

 16.superGridControl出现滚动条时 追加数据 始终显示最后一条

//SPG.PrimaryGrid.ScrollToBottom()//这个不知为什么不行 看意思好像行的样子
//如果对spg有其他操作要刷新一下 spg.Refresh()不刷新下边的代码将不起作用
SPG.PrimaryGrid.LastOnScreenRowIndex = (SPG.PrimaryGrid.Rows.Last() as GridRow).Index;

 17.superGridControl 列的数据居中对齐

spgLoginInfo.DefaultVisualStyles.CellStyles.Default.Alignment = DevComponents.DotNetBar.SuperGrid.Style.Alignment.MiddleCenter;

18.改变列头颜色

 spgLoginInfo.DefaultVisualStyles.ColumnHeaderStyles.Default.Background.Color1 = Color.FromArgb(8, 47, 76);
            spgLoginInfo.DefaultVisualStyles.ColumnHeaderStyles.Default.Background.Color2 = Color.FromArgb(8, 47, 76);

 19.superGridControl透明

            //整体透明
            superGridControl1.BackColor = Color.Transparent;
            //面板透明
            superGridControl1.DefaultVisualStyles.GridPanelStyle.Background.Color1= Color.Transparent;
            //行透明
            superGridControl1.DefaultVisualStyles.RowStyles.Default.Background.Color1 = Color.Transparent;
            //单元格透明
            superGridControl1.DefaultVisualStyles.CellStyles.Default.Background.Color1 = Color.Transparent;

            //改变单个单元格颜色
            (superGridControl1.PrimaryGrid.Rows[0] as GridRow).Cells[0].CellStyles.Default.Background.Color1 = Color.Red;
