关于gridview复选框多选问题

[chen6676869]

我想实现gridview前面设置成复选框，然后可以实现多个选择，不是全选，求实现步骤

最好附上代码感谢。

首先在第一列增加一个CheckBox控件，然后通过相关的事件，调整其位置，并相应对应的单击全选操作

        CheckBox HeaderCheckBox = null;
        public FrmNormalGridViewSelect()
        {
            InitializeComponent();

            if (!this.DesignMode)
            {
                HeaderCheckBox = new CheckBox();
                HeaderCheckBox.Size = new Size(15, 15);
                this.dgvSelectAll.Controls.Add(HeaderCheckBox);

                HeaderCheckBox.KeyUp += new KeyEventHandler(HeaderCheckBox_KeyUp);
                HeaderCheckBox.MouseClick += new MouseEventHandler(HeaderCheckBox_MouseClick);
                dgvSelectAll.CurrentCellDirtyStateChanged += new EventHandler(dgvSelectAll_CurrentCellDirtyStateChanged);
                dgvSelectAll.CellPainting += new DataGridViewCellPaintingEventHandler(dgvSelectAll_CellPainting);
            }
    }

 

事件实现了CheckBox重绘调整，并处理单击事件

        private void HeaderCheckBox_MouseClick(object sender, MouseEventArgs e)
        {
            HeaderCheckBoxClick((CheckBox)sender);
        }

        private void dgvSelectAll_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
        {
            if (e.RowIndex == -1 && e.ColumnIndex == 0)
                    ResetHeaderCheckBoxLocation(e.ColumnIndex, e.RowIndex);
        }

        private void ResetHeaderCheckBoxLocation(int ColumnIndex, int RowIndex)
        {
            Rectangle oRectangle = this.dgvSelectAll.GetCellDisplayRectangle(ColumnIndex, RowIndex, true);
            Point oPoint = new Point();
            oPoint.X = oRectangle.Location.X + (oRectangle.Width - HeaderCheckBox.Width) / 2 + 1;
            oPoint.Y = oRectangle.Location.Y + (oRectangle.Height - HeaderCheckBox.Height) / 2 + 1;
            HeaderCheckBox.Location = oPoint;
        }

        private void HeaderCheckBoxClick(CheckBox HCheckBox)
        {
            foreach (DataGridViewRow Row in dgvSelectAll.Rows)
            {
                ((DataGridViewCheckBoxCell)Row.Cells["chkBxSelect"]).Value = HCheckBox.Checked;
            }
            dgvSelectAll.RefreshEdit();
    }

我要的是gridcontrol控件的gridview - - 理解错了

[zhui22222]

往gridView的数据源
var table = gridControl.DataSource as DataTable;
添加一列类型是bool的，就可以出现选择框了

1、在GridView中某列中添加进复选框，相关的数据绑定设置成0或1进行绑定。 
2、添加事件（此代码为转载） 
        private void repositoryItemCheckEdit2_QueryCheckStateByValue(object sender, DevExpress.XtraEditors.Controls.QueryCheckStateByValueEventArgs e) 
        { 
            string val = ""; 
            if (e.Value != null) 
            { 
                val = e.Value.ToString(); 
            } 
            else 
            { 
                val = "True";//默认为选中 
            } 
            switch (val) 
            { 
                case "True": 
                    e.CheckState = CheckState.Checked; 
                    break; 
                case "False": 
                    e.CheckState = CheckState.Unchecked; 
                    break; 
                case "Yes": 
                    goto case "True"; 
                case "No": 
                    goto case "False"; 
                case "1": 
                    goto case "True"; 
                case "0": 
                    goto case "False"; 
                default: 
                    e.CheckState = CheckState.Checked; 
                    break; 
            } 
            e.Handled = true; 

        } 
3、这样就可以解决repositoryItemCheckEdit不能多选的问题

这个没法解决多选，只能是全选
