推荐答案

要显示值而不是id，您需要像这样进行更改...


首先，您需要添加drop down的select query中归档的值，如果该值不存在的话...

例如..

For displaying value instead of id you need to change like this...


first of all you need to add that value filed in your select query of your drop down if it would not there...

for example..

select name,id from student

现在像这样更改您的drop down 设计...

now change your drop down design like this...

dropdwon.datavaluefiled = "id";
dropdwon.datatextfiled = "name";

然后将dataset或datatable绑定到drop down，这样它将在drop down 文本字段中显示名称，并将id作为值显示.


为了根据选择获得价值或文本，您需要像这样的东西.

then bind your dataset OR datatable to your drop down so it will display name in drop down text filed and id as value.


for getting value or text as per selection you need something like this..

dropdown.selectedvalue //for getting id
dropdown.selecteditem.text //for getting name from dropdown

这样可以解决您的问题...

this way you can solve your problem...
