c# - Grab a List Item from the Master Page -

i have listitem in master page need assign new css class.

<ul>    <li></li>    <li id="myli" runat="server"></li>    <li></li> </ul> 

the first thing tried following:

listitem li = this.master.findcontrol("myli"); 

cannot implicitly convert type 'system.web.ui.control' 'system.web.ui.webcontrols.listitem'

then:

listitem li = (listitem) this.master.findcontrol("myli"); 

cannot convert type 'system.web.ui.control' 'system.web.ui.webcontrols.listitem'

then:

control li = this.master.findcontrol("myli"); 

but didn't find method give new css class.

sounds need grab webcontrol rather control. solution?

you need cast htmlgenericcontrol, this:

htmlgenericcontrol li = (htmlgenericcontrol)this.master.findcontrol("myli"); 

the htmlgenericcontrol has attributecollection property can use:

li.attributes.add("class", "myclass");
