重画dataGrid表头的方法

2006-06-15 15:41 381 查看

如果要调用此函数，必须在html中，<asp:datagrid>中添加如下代码：OnItemCreate="myGrid_itemCreat"

如：<asp:datagrid OnItemCreated="myGrid_itemCreat">

#region 调整表头的宽度 myGrid_itemCreat()
public void myGrid_itemCreat(object sender,System.Web.UI.WebControls.DataGridItemEventArgs e)
{
if(e.Item.ItemType==ListItemType.Header)
{
TableCellCollection tc=e.Item.Cells;
tc.Clear();

#region 前面列的处理
tc.Add(new TableHeaderCell());
tc[0].Text="xxxx";
tc[0].ColumnSpan=1;
tc[0].RowSpan = 2;
tc[0].Wrap=false;

tc.Add(new TableHeaderCell());
tc[1].Text="xxxx";
tc[1].ColumnSpan=2;
tc[1].RowSpan = 1;
tc[1].Wrap=false;

tc.Add(new TableHeaderCell());
tc[2].Text="xxxx";
tc[2].ColumnSpan=2;
tc[2].RowSpan =1;
tc[2].Wrap=false;

tc.Add(new TableHeaderCell());
tc[3].Text="xxxx";
tc[3].ColumnSpan=2;
tc[3].RowSpan = 1;
tc[3].Wrap=false;

tc.Add(new TableHeaderCell());
tc[4].Text="xxxx";
tc[4].ColumnSpan=2;
tc[4].RowSpan = 1;
tc[4].Wrap=false;

tc.Add(new TableHeaderCell());
tc[5].Text="xxxx";
tc[5].ColumnSpan=2;
tc[5].RowSpan = 1;
tc[5].Wrap=false;

tc.Add(new TableHeaderCell());
tc[6].Text="xxxx";
tc[6].ColumnSpan=2;
tc[6].RowSpan = 1;
tc[6].Wrap=false;

tc.Add(new TableHeaderCell());
tc[7].Text="xxxx";
tc[7].ColumnSpan=2;
tc[7].RowSpan = 1;
tc[7].Wrap=false;
#endregion

#region 关键处理
tc.Add(new TableHeaderCell());
tc[8].ColumnSpan=2;
tc[8].RowSpan = 1;

tc[8].Text="xxxx</tr>";
tc[8].Text+="<tr><td align=center rowspan='1' colspan='1' bgcolor='#337FB2' nowrap>xxxx</td>";
tc[8].Text+="<td align=center colspan='1' rowspan='1' valign=middle bgcolor='#337FB2' nowrap>xxxx</td>";
tc[8].Text+="<td align=center rowspan='1' colspan='1' valign=middle bgcolor='#337FB2' nowrap>xxxx</td>";
tc[8].Text+="<td align=center colspan='1' rowspan='1' valign=middle bgcolor='#337FB2' nowrap>xxxx</td>";

}
}

dataGrid的表头，其实就是与table的画法别无二致...
