解决方案

您好Mayur Vadalita，

我建议您尝试第三方自定义控件，如'infragisitic'或dev-express，如果您已准备好支付其费用。通过这种方式，您可以非常轻松地达到您的要求。



作为备用尝试构建自定义控件

查看< a href =http://www.codeproject.com/KB/aspnet/Extending_DropdownList.aspx>在DataBinding后的Dropdown控件中过滤项目 [ ^ ]。

您必须开发用户控件或自定义控件根据您的需要/设计。更好的是自定义控件。



ASP.NET不在下拉列表中提供此功能。因此，在一个控件中具有文本框，图像和列表框/ div可以用作看起来像自定义下拉列表。

如需开始参考，请使用：

多选下拉列表网络应用程序 [ ^ ]

解决方案

Hi Mayur Vadalita,
I recommend you to try third party custom controls like 'infragisitic' or dev-express, if you are ready to afford its cost. By this you can achieve your requirement very easily.

As an alternate try building a custom control

Have a look at Filter Items in the Dropdown control after DataBinding[^].

You have to develop a User control or a custom control based on your need/design. Better would be a custom control.

ASP.NET does not provide this feature in dropdownlist. Thus having a textbox, an image and a listbox/div in one control can be used to look like a custom dropdown.
For start reference, use this:
Multiselect Dropdown for Web Applications[^]
