如何在绑定到缓存的字符串数组时操作 DropDownList DataTextField

Question

我有一个绑定到缓存字符串的下拉列表[]，就像这样...

Cache["elems"] = items.elems;   //typeOf(items.elems)=string[]
DropDownList1.DataSource = Cache["elems"];
DropDownList1.DataBind();

我想限制在 DropDownList1 中显示的文本长度，例如名为 "Manufacturing" 的元素将显示 "Manufact..." 并具有值 "Manufacturing"

如何做到这一点？

感谢 Mihai Caracostea 我最终得到了这个...

    protected void DropDownList1_DataBound(object sender, EventArgs e)
    {
        foreach (ListItem myItem in DropDownList1.Items)
        {
            try
            {
                if (myItem.Text.Length > 8)
                    myItem.Text = myItem.Text.Substring(0, 11) + "...";
            }
            catch (ArgumentOutOfRangeException ex) 
            { 
                //do nothing
            }
        }
    }
