限制行数

Question

如何限制Datagridview列中的行数，让50个记录并将其他50个放入同一个Datagridview的下一列？在我的vb.net项目中，我不能上下滚动。

Datagridview从excel表中提取数据。

感谢您的帮助

Answer 1

试试这个。

dataGridView1.RowCount = 50; //Let say we have 50 rows
if (dataGridView1.Rows.Count >= 50)
{
    //TODO:
}

Answer 2

我认为这是单列表..

dim tbl as DataTable       '--------> this is your displayed table
dim nLimit as Integer = 15 '----- this is your limit as you want
dim dc as DataColumn

'get column name
dim sCol as String = tbl.Columns(0).Name
dim nRow as Integer = tbl.rows.count

'how much column ?
dim n as Integer = nRow / nLimit 
if n * nLimit < nRow then n+= 1

for x as Integer = 1 to n
    dc = New DataColumn
    dc.DataType = System.Type.GetType("System.String")
    dc.Caption = sCol & n.ToString
    dc.ColumnName = sCol & n.ToString
    tbl.Columns.Add(dc)
next

然后你可以展示它......
