[英]How to manipulate a DropDownList DataTextField when bound to a cached string array
I have a dropdownlist bound to a cached string[], like so... 我有一个绑定到缓存的字符串[]的下拉列表,就像这样...
Cache["elems"] = items.elems; //typeOf(items.elems)=string[]
DropDownList1.DataSource = Cache["elems"];
DropDownList1.DataBind();
I want to limit the length of text displayed in DropDownList1 eg an element called "Manufacturing" would display "Manufact..." and have a value "Manufacturing" 我想限制DropDownList1中显示的文本的长度,例如,名为“ Manufacturing”的元素将显示“ Manufact ...”并具有值“ Manufacturing”
How to do this? 这个怎么做?
Thanks to Mihai Caracostea I ended up with this... 多亏了Mihai Caracostea,我才结束了这个...
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
}
}
}
