CheckComboboxEdit、CheckedListBoxControl
CheckComboboxEdit
//清空项
checkedComboBoxEdit1.Properties.Items.Clear();
//自定义数组
string[] strs=new string[]{"新建","审批中","已完成","已撤销"};
//添加项
checkedComboBoxEdit1.Properties.Items.AddRange(strs);
//设置选中状态
if(checkedComboBoxEdit1.Properties.Items.Count>0){
//设置选中状态
checkedComboBoxEdit1.Properties.Items[strs[0]].CheckState = CheckState.Checked;
//设置选项是否可用
checkedComboBoxEdit1.Properties.Items[strs[0]].Enabled = false;
}
//取值
checkedComboBoxEdit1.EditValue.ToString();
//获取各项值 放在List集合中
List
//注意 当取得值是多项时，各项之间的间隔是 英文状态下 逗号+空格
//转换方法
string result = checkedComboBoxEdit1.EditValue.ToString().Replace(", ", ",");
//是否显示 确定、取消按钮
checkedComboBoxEdit1.Properties.ShowButtons = false;
//是否显示 取消按钮
checkedComboBoxEdit1.Properties.ShowPopupCloseButton = false;
//下拉显示项的个数 (设置为下拉个数加1正好可以显示全部，因为有一行是全选项)
checkedComboBoxEdit1.Properties.DropDownRows = checkedComboBoxEdit1.Properties.Items.Count + 1;
CheckedListBoxControl
//自定义一个表
DataTable dt = new DataTable();
dt.Columns.Add("ID");
dt.Columns.Add("Name");
dt.Columns.Add("Sex");
for (int i = 0; i < 30; i++) {
DataRow dr = dt.NewRow();
dr["ID"] = i + 1;
dr["Name"]=Convert.ToString((char)(65+i))+Convert.ToString((char)(65+i));
dr["Sex"] = i % 2==0?"男":"女";
dt.Rows.Add(dr);
}
//清空项
checkedListBoxControl1.Items.Clear();
//绑定
checkedListBoxControl1.DataSource = dt;
checkedListBoxControl1.ValueMember = "ID";
checkedListBoxControl1.DisplayMember = "Name";
//全选
//checkedListBoxControl1.CheckAll();
//项的个数
int itemCount = checkedListBoxControl1.ItemCount;
//添加项（如果设置绑定，添加项无效）
checkedListBoxControl1.Items.Add("kk");
//设置选中状态、显示值、实际值、是否可用（如果设置绑定，这些将会无效）
checkedListBoxControl1.Items[0].CheckState = CheckState.Checked;
checkedListBoxControl1.Items[0].Description = "显示值";
checkedListBoxControl1.Items[0].Value = "实际值";
checkedListBoxControl1.Items[0].Enabled = false;
//效果和上面一样
checkedListBoxControl1.SetItemChecked(0, true);
checkedListBoxControl1.SetItemCheckState(0, CheckState.Checked);
checkedListBoxControl1.SetItemValue("实际值",0);
//是否被勾选
bool isChecked= checkedListBoxControl1.GetItemChecked(0);
//获取某项状态
string checkState = checkedListBoxControl1.GetItemCheckState(0).ToString();
//获取某项绑定值 valueMember
string trueValue = checkedListBoxControl1.GetItemValue(0).ToString();
//获取某项显示值 displayMember
string disValue = checkedListBoxControl1.GetDisplayItemValue(0).ToString();
string disValue2 = checkedListBoxControl1.GetItemText(0);
//是否点击一次 就改变状态
checkedListBoxControl1.CheckOnClick = true;
//是否多列显示
checkedListBoxControl1.MultiColumn = true;
//checkedListboxControl 是否获得焦点
bool isfocus=checkedListBoxControl1.ContainsFocus;
//实现单选功能
checkedListBoxControl1.SelectedIndexChanged += new EventHandler(checkedListBoxControl1_SelectedIndexChanged);
//获取选中项的绑定值（前提：手动添加的可以获取，但是datatable绑定的无法获取）
List
void checkedListBoxControl1_SelectedIndexChanged(object sender, EventArgs e)
