新建一网页,添加一GridView1和一Button1,并手动设置了GRIDVIEW1的列(a,b,c,列头为a,b,c),设定其打开分页功能,每页显示10行
Button1_Click为GRIDVIEW添加并显示了数据,GRIDVIEW1也显示了分页链接,但是点击链接并不能到达下一页,提示:
System.Web.HttpException: GridView“GridView1”激发了未处理的事件“PageIndexChanging”。
请问:这种情况下,怎么能实现分页功能??
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Dim currentTable As New DataTable
Dim row As DataRow
Dim i As Integer, j As Integer
For i = 0 To 100
row = currentTable.NewRow()
currentTable.Rows.InsertAt(row, i)
Next
GridView1.DataSource = currentTable
GridView1.DataBind()
For i = 0 To GridView1.Rows.Count - 1
For j = 0 To GridView1.Columns.Count - 1
GridView1.Rows(i).Cells(j).Text = (i + 1) * (j + 1)
Next
Next
