下拉列表值的获取及赋值

[password]123456[/password]
根据输入的显示值;获取选中的下拉Key: ----导入

public string GetCombValueByCaption(string fieldKey, string value)
{ //获取下拉值
string enumItemValue = "";
try
{
Field field = this.View.BusinessInfo.GetField(fieldKey);
ComboField comboField = field as ComboField;
var enumObj = (EnumObject) comboField.EnumObject;
//根据枚举值获取枚举项，然后拿枚举项的枚举名称
enumItemValue =
enumObj.Items.FirstOrDefault(
p =>
p.Caption.ToString().Equals(value.Trim())).Value.ToString();

}
catch (Exception exception)
{

}
return enumItemValue;
}

根据下拉选中的key 得到 显示的值： ----导出

public string GetCombCaptionByValue(string fieldKey, string value)
{ //获取下拉值
string enumItemValue = "";
try
{
Field field = this.View.BusinessInfo.GetField(fieldKey);
ComboField comboField = field as ComboField;
var enumObj = (EnumObject) comboField.EnumObject;
//根据枚举值获取枚举项，然后拿枚举项的枚举名称
enumItemValue =
enumObj.Items.FirstOrDefault(
p =>
p.Value.ToString().Equals(value.Trim())).Caption.ToString();
}
catch (Exception exception)
{

}
return enumItemValue;
}
