Was the site upgraded from 7 to 8? HTMLHelper was moved from GlobalHelper to Helpers.

If this wasn't a recent upgrade, you might have to install a fresh copy of 8.2 and replace the webpart in your solution, otherwise you need to make sure the upgrade was done properly.

Hi Zach, Thank you for your answer but I can see that correct dll is referenced in the web part and the bin folder has CMS.Helpers.dll

using CMS.Controls;

using CMS.Helpers;

using CMS.PortalControls;

using CMS.SiteProvider;

using CMS.Membership;

using CMS.Search;

in file inetpub\KenticoCMS_Main\CMS\CMSWebParts\SmartSearch

I would also check the control for the webpart \CMSModules\SmartSearch\Controls\SearchDialog.ascx.cs

If you upgraded your site from a version 7 site, you also needed to update the transformations. I'd suggest looking at the transformation that webpart is utilizing. Most likely there is a reference to the CMSContext class which is no longer valid in v8.

Hi Brenden Thank you for the help. The full error message is

TempITemplate.Template]: http://server/CMSVirtualFiles/Transformations/=vg=1c8798a6-3265-418e-a0d1-876e6a5962a7/CMS.Root/SmartSearchResults.ascx(6): error CS0234: The type or namespace name 'HTMLHelper' does not exist in the namespace 'CMS.GlobalHelper' (are you missing an assembly reference?)[

I do not see any CMSVirtualFiles folder so I am not sure where to look for the CMSContext reference.

You can edit the transofrmation by going to page types, searching for root, and clicking transformations in the left menu, and finding the SmartSearchResults transformation. I believe this should be the default:

<div style="margin-bottom: 30px;">
    <%-- Search result title --%>
    <div>
        <a style="font-weight: bold" href='<%# SearchResultUrl() %>'>
            <%#SearchHighlight(HTMLHelper.HTMLEncode(CMS.ExtendedControls.ControlsHelper.RemoveDynamicControls(DataHelper.GetNotEmpty(Eval("Title"), "/"))), "<span style='font-weight:bold;'>", "</span>")%>
      </a>
    </div>
    <%-- Search result content --%>
    <div style="margin-top: 5px; width: 590px;">
        <%#SearchHighlight(HTMLHelper.HTMLEncode(TextHelper.LimitLength(HttpUtility.HtmlDecode(HTMLHelper.StripTags(CMS.ExtendedControls.ControlsHelper.RemoveDynamicControls(GetSearchedContent(DataHelper.GetNotEmpty(Eval("Content"), ""))), false, " ")), 280, "...")), "<span style='background-color: #FEFF8F'>", "</span>")%><br />
    </div>
    <%-- Relevance, URL, Creattion --%>
    <div style="margin-top: 5px;">
        <%-- Relevance --%>
        <div title="Relevance: <%# Convert.ToInt32(ValidationHelper.GetDouble(Eval("Score"), 0) * 100) %>%"
            style="width: 50px; border: solid 1px #aaaaaa; margin-top: 7px; margin-right: 6px; float: left; color: #0000ff; font-size: 2pt; line-height: 4px; height: 4px;">
            <div style='<%# "background-color:#a7d3a7;width:" + Convert.ToString(Convert.ToInt32(ValidationHelper.GetDouble(Eval("Score"), 0) * 50)) + "px;height:4px;line-height: 4px;" %>'>

        </div>

Sofia, you need to look specifically in the webpart properties and look for the transformation. In there edit it and look for the CMSContext. The transformations aren't stored in the file system, they are stored in the database and you access them through the Kentico UI.

Still didn't answer the question, did you upgrade your site from version 7?

I modified the transform as below and now it has started working. Thanks Zach and Brenden for your timely help today. Greatly appreciated.

<div style="margin-bottom: 30px;">

        </a>
    </div>
    <%-- Search result content --%>
    <div style="margin-top: 5px; width: 590px;">
        <%#SearchHighlight(HTMLHelper.HTMLEncode(TextHelper.LimitLength(HttpUtility.HtmlDecode(HTMLHelper.StripTags(CMS.ExtendedControls.ControlsHelper.RemoveDynamicControls(GetSearchedContent(DataHelper.GetNotEmpty(Eval("Content"), ""))), false, " ")), 280, "...")), "<span style='background-color: #FEFF8F'>", "</span>")%><br />
    </div>
    <%-- Relevance, URL, Creattion --%>
