In a list with a field type “Choice” you can know available options of this field from codebehind without reading all list values and not making them unique with Distinct(). Especially, you can’t just read and make Distinct() list values if your field allows multiple choice or if you don't have all options. (read more...)

Today I needed to know a quantity of SharePoint List. Somewhy SharePoint doen't give this information using common tools. But using PowerShell it appeared to do easy. (read more...)

With coming up Visual studio 2012 finally I decided to try it. But first I need to uninstall Visual Studio 2010. When I entered Control Panel -> Programs and Features I saw a lot of products that have been installed with VS 2010. It was hard to think about uninstalling each element manually.  (read more...)

Working with SharePoint lists I often use lookup values. But when I write C# solutions for lists I have some difficulties with LookUp Values. Trying to get LookUp Value as string it looks like "213;#lookup value". (read more...)

For deleting SharePoint groups you can use SharePoint Designer. For this you should open site in SPDesigner, in left column goto "Site Groups", select groups for deleting and press Delete button on keyboard or in ribbon. But this process doesn't always work. And when I wanted to remove user groups SPDesigner hanged and reported error of deleting. (read more...)

If you made a developer machine for SharePoint on Windows 7 (x64), you must remember - run visual studio only "Run as administrator" even if your account is administrator for developing SharePoint solutions.

Or you can turn off ULC but I don't recomend it.

While testing SharePoint solution with SPLists I often need empty list. I'd like to have analog for "Truncate" in SQL, but there's nothing for SharePoint.

So I wrote a short PowerShell script for deleting all items in SharePoint List. Here it is (read more...)

I found very nice extender for Ditto Modx.

When using snippet Ditto with custom page Ids, you have strange sorting - I haven't even understood which one.

For sorting documents as you write in &documents=`[x, xx, xxx, xxxx]` you shoul use the ditto-extender below.

Write Ditto callout this way:

[[Ditto? &tpl=`razdel200` &documents=`[1,4,3,5,212,23,44]` &extenders=`customsort`  ]]

You should save file "customsort.extender.inc.php" in assets/snippets/ditto/extenders/

<?php

if (!function_exists('customsort'))
{
function customsort($a, $b)
{
$pos_a=array_search($a['id'],$GLOBALS['documents']);
$pos_b=array_search($b['id'],$GLOBALS['documents']);

if ($pos_a == $pos_b)
{
return 0;
}
return ($pos_a < $pos_b)?-1:1;
}
}

$GLOBALS['documents']=explode(',',$documents);
$orderBy["custom"][] = array ("id", "customsort");
$ditto->advSort = true;

?>

Then documents are in the order you needed.
