如何在AspxGridView的编辑模式下隐藏级联的组合框. [英] How to hide cascaded combo boxes in edit mode of AspxGridView.

问题描述

嗨
当在AspxGridview的编辑模式下使用时，能否请您提供一些解决方案，以使级联下拉菜单按预期工作.
我正在使用DevExpress控件.

我的要求如下:

如果我选择country ="United States"，则填充州"组合框，并在选择州"时填充城市"组合框.

如果我选择国家/地区"以外的其他名称，则选择美国"，然后仅使用所选国家/地区"的城市填充城市"组合框，而无需填充州"组合框.另外，我需要隐藏状态"组合框.

Hi
Can you please provide me some resolution to make the cascading dropdowns work as expected when used inside edit mode of AspxGridview.
I am using DevExpress Controls.

My requirement is as follow:

If I select country="United States" then populate the "State" combobox and on selection of "State" populate the "City" combobox.

If I select "country" other then "United States" then populate only "City" combobox with cities of selected "country" and no need to populate the "State" combobox. Also I need to hide the "State" combobox.

i.e. like----------Country---------State--------City
---------ROW1------united states---Alaska-------Douglas
---------ROW2------Canada-----------------------Toronto
---------ROW3------Australia--------------------Sydeny
---------ROW4------united states---California---Yuba City

在Editmode中也需要相同的内容.
请帮助我，我需要尽快.

问候，
Pankaj.

Same is required in Editmode also.
Please help me I need to do it ASAP.

Regards,
Pankaj.

推荐答案

Protected Sub ddlCountry_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs)
      If ddlCountry.SelectedItem.Value = "US" Then
             ddlState.Visible = True
             txtState.Visible = False
             PopulateState();//Based on Country
      Else
             ddlState.Visible = False
             txtState.Visible = True
             PopulateCity();//Based on Country
      End If
End Sub

顺便说一句，根据您的需要进行更改.

BTW Do changes based on your need.
