c# - ASP.NET GridView : Get the PageIndex from the selected Row

Question

我需要在 gridview 中突出显示已编辑行的功能，因此在 gridview 的 RowDataBound 上我检查哪一个是已编辑的行并更改 css 样式。 有一个小问题，更改可能会使该行显示在不同的页面上。 如何从行中获取 PageIndex 以跳转到该页面？

Answer 1

untested code in vb.net


*assuming there are studentid from 1 to 100 in the database
*assuming pagesize of gridview is 10


dim studentid_of_edited_row as integer = 11


dim da as new dataadapter(strquery,conn)
dim dt as new datatable
da.fill(dt)


dim desired_pageindex as integer = 0


for i as integer = 0 to dt.rows.count - 1
  if dt.rows(i)("studentid") = studentid_of_edited_row then
    desired_pageindex = i / gridview1.pagesize
    exit for
  end if
next


gridview1.pageindex = desired_pageindex
gridview1.datasource = dt
gridview1.databind
