Taking off Anchor Tag in Drop Down List

A while ago, I encountered a issue about lookup column in a SharePoint list.
If lookups items are over 20 items, lookup column changes the visual.


Under 20 items:



Over 20 items (You can modify in the drop down list.) : 



I found the solution not to change the visual if lookups are over 20 items in bellow blog post.

Sharepoint lookups over 20 items solution?
(The solution is using DVDropDownList instead of FormField.)


I could resolve my issue referencing the post, but I encountered a new problem. The problem is that a lookup column is extended due to anchor tag in EditForm.aspx.



The resolution is using xlst to take off Anchor Tag.


The code is here. I add xslt code and fix SharePoint:DVDropDownList element.

<td width="400px" valign="top" class="ms-formbody">
  <xsl:variable name="lookup" select="substring-after(substring-before(/dsQueryResponse/Rows/Row/@test, '&lt;/a&gt;'), '&quot;&gt;')" />
  <SharePoint:DVDropDownList runat="server" id="ff4{$Pos}" __designer:bind="{ddwrt:DataBind('u',concat('ff4',$Pos),'SelectedValue','SelectedIndexChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@test')}" selectedvalue="{$lookup}" datasourceid="spdatasource1" datatextfield="Title" datavaluefield="ID" AppendDataBoundItems="True" CausesValidation="True"/>


Also see substring-before function and substring-after function.

How to Get Workflow History Programmatically

I introduced how to check workflow status in the last post.
Today, I introduce how to get workflow history from Workflow History List. You can find Workflow History List's URL by using SharePoint Designer.



Workflow History List is here. There are some columns associated with workflow.



The code is here. The code enables to get all workflow status associated each item in SharePoint site. You can modify the code to get a specific list's workflow status. I identify workflow history list item using "Workflow History Parent Instance" column and "Primary Item ID" column.(see "if" block.)

using System;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Workflow;

// This is Console Application //

SPSite site = new SPSite("http://sharepoint-site");
SPWeb web = site.OpenWeb();

foreach (SPList list in web.Lists)
{
    foreach(SPListItem item in list.Items)
    {
        foreach (SPWorkflow workflow in item.Workflows)
        {
            foreach (SPListItem worflowHistoryItem in workflow.HistoryList.Items)
            {
                if (("{" + workflow.InstanceId.ToString() + "}" == worflowHistoryItem["Workflow History Parent Instance"].ToString()) 
                    && (item.ID.ToString() == worflowHistoryItem["Primary Item ID"].ToString()))
                {
                    Console.WriteLine(item.Name + " : " + worflowHistoryItem["Description"]);
                }
            }
        }
    }
}
