javascript - Problems with using hyperlinks in asp.net

Question

1. I am currently working on a project with asp.net and use GridView for data binding. The binding method is the result of the gridview binding database query set in the background:

The problem I encountered is that I want to send the student ID to the target page when clicking the hyperlink. How should I do this?
The picture below is the property window corresponding to the field of admission ticket number:

How can I modify it to pass the current student ID to the RightMain.aspx page?

Also, my current page displays two columns. How can I delete the column on the right? I am a beginner in .net and I don’t quite understand it. Please give me some advice!

Answer 1

CommandArgument="field name"
Use e.CommandArgument in the Gridview command to get it
Or write it in the Template<a href='url?要传值的名称=<%# bind("字段名")%>'/>
Use request.Querstring["name of the value to be passed"] in the .cs of the directed url to get it
