推荐答案

请与您实际使用网格投标数据的代码段共享.
您是否尝试过调试?
您是否可以从数据库中获取数据?

有3个简单的步骤.
1.在"DropDown List SelectedIndex Changed"上，采用选定的值
2.根据为下拉列表选择的值来调用后端数据库.将数据保存在数据集中或任何需要的地方.
3.将其与Grid视图绑定.

Please share your code snippets where you actually biding data with grid.
Have you tried debugging?
Are you able to fetch data from Database?

There are 3 simple step.
1. On DropDown List SelectedIndex Changed, take the selected values
2. Call you back end database based on the selected value for the dropdown list. Save the data in a dataset or where ever you want.
3. Bind it with Grid view.

您可以通过itemtemplate中的控件ID(列表框)访问列表框.

C#代码:

ListBox myListBox =(ListBox)gridviewname.rows.FindControl("ListBox1");

希望这会有所帮助.
谢谢

You can access the listbox through id of the control(listbox) from itemtemplate.

c# code:

ListBox myListBox = (ListBox)gridviewname.rows.FindControl("ListBox1");

hope this will help.
