[解决办法]
((CheckBox)this.DataGrid1.Items[i].Cells[4].Controls[1])
会不会是Controls[0]?
[解决办法]
<ItemTemplate>
<asp:CheckBox ID= "CheckBox1 " runat= "server " Text= ' <%# DataBinder.Eval(Container.DataItem, "business_id ") %> '/>
</ItemTemplate>
－－－－－－－－－－
从这里来看应该是((CheckBox)this.DataGrid1.Items[i].Cells[4].Controls[０])
[解决办法]
你也可以用findcontrol方法
for (int i = 0; i < DataGrid1.Items.Count; i++)
{
box = ((CheckBox)this.DataGrid1.Items[i].Cells[4].findcontrol( "CheckBox1 "));
if (box.Checked)
{
Response.Write(box.Text);
}
}
[解决办法]
((CheckBox)this.DataGrid1.Items[i].findcontrol( "CheckBox1 "));
[解决办法]
最好用((CheckBox)this.DataGrid1.Items[i].findcontrol( "CheckBox1 "));
