How to save a third value in each ListItem of an ASP.NET dropdownlist? -

each listitem in asp.net has value property , text property. need have 3rd value saved also. hack concatenate special separator , 3rd value value property. using findbyvalue method makes cumbersome.

is there improve way save 3rd value or way utilize findbyvalue. (i can't utilize findbytext). wish there tag property.

if using binded dropdownlist, defined datatextfield , datavaluefield properties, there's not way save 3rd value on dropdownlist itself. save separately tho.

if you're defining dropdownlist through markup, seek defining custom attribute:

<asp:dropdownlist id="ddldummy" runat="server"> <asp:listitem text="x" value="y" thirdvalue="z" /> </asp:dropdownlist>

for retrieving it, utilize findbyvalue , thirdvalue attribute listitem:

listitem item = ddldummy.items.findbyvalue("y"); string value = item.attributes["thirdvalue"];

however, weirdly, if generate items dynamically, attributes not persisted:

protected void page_load(object sender, eventargs e) { if(!ispostback) { listitem item = new listitem("x", "y"); item.attributes.add("thirdvalue", "z"); ddldummy.items.add(item); } }

if case, take @ question gives work arround:

listitems attributes in dropdownlist lost on postback?

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
