Devexpress GridControl中 repositoryItemCheckEdit作为选择列以及作为显示列的使用方法

Posted 2020-11-26 dinggf

一、在gridcontrol列表控件中使用单选框作为选择列,这里有两种方式。

方式一:选择gridcontrol控件的Run Designer按钮,添加一列,设置该列的ColumnEdit为checkedit。如下图:

代码如下:

private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                List<Student> studentList = new List<Student> { new Student() { Selected="N",Name="张三",Age=22 }, 
                new Student() { Selected="N",Name="李四",Age=20 }, new Student() { Selected="N",Name="王五",Age=24}};
                repositoryItemCheckEdit1.ValueUnchecked = "N";
                //定义选中状态值
                repositoryItemCheckEdit1.ValueChecked = "Y";
                //绑定数据
                gridControl1.DataSource = studentList;
                //gridControl2.DataSource = studentList;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

        /// <summary>
        /// 得到选中项
        /// </summary>
        private void simpleButton1_Click(object sender, EventArgs e)
        {
            try
            {
                if (gridView1.FocusedRowHandle >= 0)
                {
                    string str = string.Empty;
                    for (int i = 0; i < gridView1.RowCount; i++)
                    {
                        if (gridView1.GetRowCellValue(i, "Selected").ToString().Equals("Y"))
                        {
                            if(string.IsNullOrEmpty(str))
                            {
                                str = gridView1.GetRowCellValue(i, "Name").ToString();
                            }
                            else
                            {
                                str+="
"+ gridView1.GetRowCellValue(i, "Name").ToString();
                            }
                        }
                    }
                    MessageBox.Show(str);
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
 public class Student
    {
        public string Selected { get; set; }
        public string Name { get; set; }
        public int Age { get; set;}
    }

效果图:

 

方式二:选择gridcontrol控件的Run Designer按钮,选中gridview,设置gridview的MultiSelect和MultiSelectMode属性。如下图:

代码如下:

private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                List<Student> studentList = new List<Student> { new Student() { Selected="N",Name="张三",Age=22 }, 
                new Student() { Selected="N",Name="李四",Age=20 }, new Student() { Selected="N",Name="王五",Age=24}};
                //repositoryItemCheckEdit1.ValueUnchecked = "N";
                //定义选中状态值
                //repositoryItemCheckEdit1.ValueChecked = "Y";
                //绑定数据
                //gridControl1.DataSource = studentList;
                gridControl2.DataSource = studentList;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
         /// <summary>
        /// 得到选中项
        /// </summary>
  private void simpleButton2_Click(object sender, EventArgs e)
        {
            try
            {
               int[] rowIndex=gridView2.GetSelectedRows();
                string str = string.Empty;
                foreach (int index in rowIndex)
                {
                    if (string.IsNullOrEmpty(str))
                    {
                        str = gridView1.GetRowCellValue(index, "Name").ToString();
                    }
                    else
                    {
                        str += "
" + gridView1.GetRowCellValue(index, "Name").ToString();
                    }
                }
                MessageBox.Show(str);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }

效果图如下:

 

二、在gridcontrol列表控件中使用单选框作为显示列

选择gridcontrol控件的Run Designer按钮,添加一列,设置该列的ColumnEdit为checkedit,设置gridview的optionscolumn的AllowEdit为false(设置改列不可编辑)。如下图

代码如下:

private void Form1_Load(object sender, EventArgs e)
        {
            try
            {
                 List<Student> studentList = new List<Student> { new Student() { Selected="N",Name="张三",Age=22,IsStudent=true },
                new Student() { Selected="N",Name="李四",Age=20,IsStudent=true }, new Student() { Selected="N",Name="王五",Age=24,IsStudent=false}};
                repositoryItemCheckEdit3.CheckStyle = DevExpress.XtraEditors.Controls.CheckStyles.Standard;
                //复选框加载的状态     实心   空心   空心打勾  
                repositoryItemCheckEdit3.NullStyle = DevExpress.XtraEditors.Controls.StyleIndeterminate.Unchecked;
                //绑定数据
                gridControl1.DataSource = studentList;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }    

    public class Student
    {
        public string Selected { get; set; }
        public string Name { get; set; }
        public int Age { get; set; }

        public bool IsStudent { get; set; }
    }

效果图如下:
