javascript - Toggle HtmlEncode on asp:BoundField -


title pretty self explanatory. have 2 bound fields , want toggle them function (either js or c#). i'm not sure how since not have id elements.

here code: 

<asp:boundfield datafield="fieldoldvalue" headertext="fieldoldvalue" htmlencode="false"/> <asp:boundfield datafield="fieldnewvalue" headertext="fieldnewvalue" htmlencode="false"/>  <label class="switch">   <input id="htmltoggle" type="checkbox" onclick="togglehtml()">   <span class="slider round"></span> </label>

ideally js this:

function togglehtml() {   if('htmltoggle'.checked) //render html (htmlencode="false")   else //un-render html (htmlencode="true") }

the fields showing raw html initially, , when hit toggle, both fields render html.

update: have maybe gotten closer solving still not getting work (i'm trying either asp:button or toggle). here more code:

currently trying button:

<asp:button runat="server" text="swap" id="htmltoggle2" class="btn" onclick="swaphtml"/>

c#: 

protected void swaphtml(object sender, eventargs e)         {             if (((boundfield)gridview2.columns[2]).htmlencode.equals(false))             {                 ((boundfield)gridview2.columns[2]).htmlencode = true;                 ((boundfield)gridview2.columns[3]).htmlencode = true;             }             else             {                 ((boundfield)gridview2.columns[2]).htmlencode = false;                 ((boundfield)gridview2.columns[3]).htmlencode = false;             }         }
