Hi, I have a ListBox with more that 1000 Items with text and value properties.
I like to filter the text entered in a textbox.. For example.
dim txt = textbox1.text
For each itm in ListBox.items
if not itm.text = txt then
itm.hide()
end if
Next
Some idea? thanks.
Items in a ListBox don’t have properties, they are usually just strings. If you use objects as items they are just objects that return a string. That’s the standard behavior of list boxes.
However, the items on the client (in the javascript widget of the listbox) can be hidden. So:
If you filter on the client, and you want to hide item 3, for example:
listBox1.getChildren()[3].exclude(); <– used exclude(), not hide() otherwise the item will be hidden but still used for the layout.
If you filter on the server, you have to remove the item:
this.listBow1.Items.RemoveAt(3);
