ASP.NET中GridView设计汇总

Row内找Label控件

//DataGrid超级连接列
DataNavigateUrlField="字段名" DataNavigateUrlFormatString="http://xx/inc/delete.aspx?ID={0}"

//DataGrid行随鼠标变色
private void DGzf_ItemDataBound

if (e.Item.ItemType!=ListItemType.Header)
{

/""+e.Item.Style["BACKGROUND-COLOR"]+"/"");

读取DataGrid控件TextBox值

foreach(DataGrid dgi in yourDataGrid.Items)
{
TextBox tb = (TextBox)dgi.FindControl("yourTextBoxId");
tb.Text....
}
datagrid选定比较底下的行时，为什么总是刷新一下，然后就滚动到了最上面，刚才选定的行因屏幕的关系就看不到了

page_load
page.smartNavigation=true

24.在Datagrid中修改数据，当点击编辑键时，数据出现在文本框中，怎么控制文本框的大小 ?

private void DataGrid1_ItemDataBound(obj sender,DataGridItemEventArgs e)
{
for(int i=0;i<e.Item.Cells.Count-1;i++)
if(e.Item.ItemType==ListItemType.EditType)
{
e.Item.Cells[i].Attributes.Add("Width", "80px")
}
}
