求助:关于datagrid的简单问题
请问我在DataGrid对象Grid1中加入了一个checkbox模板列chk 希望在页面提交时将被选选种的行对象保存进一个对象数组object[] rowob中请问chk的OnCheckedChanged事件该如何写呀?谢谢各位了!
------解决方案--------------------
ArrayList arrObject = new ArrayList();
for (int i = 0; i < DataGrid.Rows.Count; i++)
{
CheckBox cbs = DataGrid.Rows[i].Cells[0].FindControl( "sSelect ") as CheckBox;
if (cbs.Checked)
{
int sid = int.Parse(DataGrid.Rows[i].Cells[1].Text.ToString().Trim());
arrObject.Add(sid);
}
}

just try this following demo：

{
if (!IsPostBack) {
// 首次加载数据一定要放在 !IsPostBack 内，

LoadProductData();
}
}
void chk_CheckedChanged(object sender, EventArgs e)
{
// 触发此事件的 CheckBox
CheckBox chk = sender as CheckBox;
// 得到 CheckBox 所在行
DataGridItem item = chk.NamingContainer as DataGridItem;
// 得到 DataGrid，当然这里可以直接引用控件ID
DataGrid grd = item.NamingContainer as DataGrid;
// 得到主键

{
