gridview动态生成列的问题

Question

Datasource的数据源是Arraylist，而且列数无法确定，要根据查询结果动态的生成。由于对Arraylist的结构不是很清楚，我不知道该怎样动态的设定每一列的DataFeild和HeaderText，请高手支招。

Answer 1

下面的代码可以自动排序，试试。http://bingning.net
private void Form1_Load(object sender, EventArgs e)
{    DataGridView1.RowsAdded += new DataGridViewRowsAddedEventHandler(
        DataGridView1_RowsAdded);
    DataGridView1.CellValueChanged += new DataGridViewCellEventHandler(
        DataGridView1_CellValueChanged);
    DataGridView1.ColumnHeaderMouseClick += new DataGridViewCellMouseEventHandler(
        DataGridView1_ColumnHeaderMouseClick);
}
private void DataGridView1_ColumnHeaderMouseClick(object sender,
    DataGridViewCellMouseEventArgs e)
{
    DataGridViewColumn clickedColumn = DataGridView1.Columns[e.ColumnIndex];
    if (clickedColumn.SortMode != DataGridViewColumnSortMode.Automatic)
        this.SortRows(clickedColumn, true);
}
private void DataGridView1_RowsAdded(object sender,
    DataGridViewRowsAddedEventArgs e)
{
    this.SortRows(DataGridView1.SortedColumn, false);
}
private void DataGridView1_CellValueChanged(object sender,
    DataGridViewCellEventArgs e)
{
    if (DataGridView1.SortedColumn != null &&
        e.ColumnIndex == DataGridView1.SortedColumn.Index)
        this.SortRows(DataGridView1.SortedColumn, false);
}
private void SortRows(DataGridViewColumn sortColumn, bool orderToggle)
{
    if (sortColumn == null)
        return;    if (sortColumn.SortMode == DataGridViewColumnSortMode.Programmatic &&
        DataGridView1.SortedColumn != null &&
        !DataGridView1.SortedColumn.Equals(sortColumn))
    {
        DataGridView1.SortedColumn.HeaderCell.SortGlyphDirection =
            SortOrder.None;
    }    ListSortDirection sortDirection;
    if (orderToggle)
    {
        sortDirection =
            DataGridView1.SortOrder == SortOrder.Descending ?
            ListSortDirection.Ascending : ListSortDirection.Descending;
    }
    else
    {
        sortDirection =
            DataGridView1.SortOrder == SortOrder.Descending ?
            ListSortDirection.Descending : ListSortDirection.Ascending;
    }
    SortOrder sortOrder =
        sortDirection == ListSortDirection.Ascending ?
        SortOrder.Ascending : SortOrder.Descending;    DataGridView1.Sort(sortColumn, sortDirection);    if (sortColumn.SortMode == DataGridViewColumnSortMode.Programmatic)
    {        sortColumn.HeaderCell.SortGlyphDirection = sortOrder;
    }
}

由于每次生成的arraylist的列数和里面的属性值是不定的，我生成gridview时，怎样把arraylist里的属性名动态赋给HeaderText，并把属性值赋给DataField呢？

Answer 3

  BoundField bf = new BoundField();
                bf.HeaderText = "Item";
                ScheduleGrid.Columns.Add(bf);
                DataSet ds = GridBind.GridViewBind(reportType, productType);
             //数据动态绑定
                for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
                {
                        BoundField bf1 = new BoundField();
                        bf1.DataField = ds.Tables[0].Rows[i][1].ToString();
                        bf1.HeaderText = ds.Tables[0].Rows[i][1].ToString();
                        ScheduleGrid.Columns.Add(bf1);
                      
                }
