                            new SelectListItem { Text="25,000", Value="6"},

                            new SelectListItem { Text="35,000", Value="8"},
                            new SelectListItem { Text="40,000", Value="9"},
                            new SelectListItem { Text="50,000", Value="10"},
                            new SelectListItem { Text="60,000", Value="11"},
                            new SelectListItem { Text="70,000", Value="12"},
                            new SelectListItem { Text="80,000", Value="13"},
                            new SelectListItem { Text="90,000", Value="14"},
                            new SelectListItem { Text="1,00,000", Value="15"},
                            new SelectListItem { Text="5,00,000", Value="16"},
                            new SelectListItem { Text="10,00,000", Value="17"}
                              }, new { @class = "selectpicker" })

public ActionResult DisplayDetails(Search objCust)
{
    objCust.Minimim = Convert.ToDecimal(Request.Form["Minimim"]);
}

但是在这里，我得到选择的值，但没有选择文本".我如何在这里获取所选文本.

But here i am getting selected value but not it selected Text. How i can get the selected text Here.

推荐答案

您有两个选择，

选项1 .将Value =文本放在下拉列表中

Option 1. put Value = Text in dropdown

选项2 .取一个名称为"MinimumValue"的隐藏字段，然后在表单字段中将选定的下拉文本提交到隐藏字段"MinimumValue"中，然后可以将值获取为Request.Form ["MinimumValue"]

Option 2. Take one Hidden field with some Name say "MinimumValue" and before submitting the form store selected dropdown text in hidden field "MinimumValue" then you can get the value as Request.Form["MinimumValue"]
