C#选择弹框控件使用（可多选）

点击事件触发此方法

private void selectCurryCode_ButtonClick(object sender, DevExpress.XtraEditors.Controls.ButtonPressedEventArgs e)

{

判断所选是否为空
if (this.SelectBeneficiary == null)
return;

//获取待选择项

通过字典获取数据方法获取对应数据
var dictList = VineERP.Utils.CommonDictHelper.GetCommonDictList("Currency");

判断是否存在数据
if (dictList == null || dictList.Count == 0)
return;

构造弹框

frmSelectedDialog<sys_common_dict> dialog = new frmSelectedDialog<sys_common_dict>("Code,CodeName", "代码,币种", "50,80");
dialog.AllowMultiSelect = true; //设置多选

获取控件所分配的窗体
dialog.Parent = this.ParentForm;
//根据当前内容，设置已选项
if (!string.IsNullOrEmpty(this.SelectBeneficiary.CurrencyCode))
{

将已选择项进行拆分
var codeArr = this.SelectBeneficiary.CurrencyCode.Split(',').ToList();
dialog.SelectedEntities = new List<sys_common_dict>();

默认勾选已选
foreach (var code in codeArr)
{
var dict = dictList.Find(p => p.Code == code);
if (dict != null)
dialog.SelectedEntities.Add(dict);
}
}
//传递待选择项，并返回选择项并处理
dialog.ShowDialog(dictList, p =>
{
if (p.SelectedEntities == null || p.SelectedEntities.Count == 0)
return;

this.SelectBeneficiary.CurrencyCode = string.Empty;

显示所有数据

foreach (var dict in p.SelectedEntities)
{
this.SelectBeneficiary.CurrencyCode += string.Format("{0}{1}",
string.IsNullOrEmpty(this.SelectBeneficiary.CurrencyCode) ? "" : ",", dict.Code);
}

});
}
