Custom Views for Multiple Content Types within a Single List

In this example, we have two custom content types based off the Event list content type: (1) “Event Type 1”, with single line text fields “Column A” and “Column B”, and (2) “Event Type 2”, with single line text fields “Column Y” and “Column Z”. Create a Calendar, “Sample Calendar”, and add these two content types to the list. After creating an event of both content types, we see that the add, edit, and display forms all act as we would hope – only columns in that content type appear.

Figure 1 – Add/Edit Event Type 1

Figure 2 – Add/Edit Event Type 2

Figure 3 – View Event Type 1

Figure 4 – View Event Type 2

However, we may not need the Category, All Day Event, Recurrence, or Workspace columns. In this example, we want to remove them from the views. Open SharePoint Designer 2010, open your site, and click on the list. On the right, there is a section for Forms.

Click New… and create a new item form that is and use the content type Event Type 1.

Now this form will appear in the Forms panel.

Click nf1.aspx to edit the form. From the split view, find the table row tags containing the columns you want to delete and remove these lines from the page. Set this as the default New Form page, and create a new Event Type 1 event. Creating an event of Event Type 1, it seems all is set.

However, now when we go to create an event of Event Type 2, we get the same new form as in Event Type 2. We need to create a new form for Event Type 2 in the same way we did for Event Type 1 above.
If we set this new form to be the default, we run into the same issue when we try to create an event of Event Type 1. To resolve this, we need to associate the form with the content type itself, not with the list. Click on the sample calendar in SharePoint Designer. At the bottom left, there is a panel for Content Types.

Click on our content type Event Type 1. On the top right, there is a panel for Forms.

Click the section for New Form to enter the URL of our custom new form, enter the URL, hit Enter, and save your changes.

Do the same for Event Type 2. Now when we try to add an event of each content type, we get the appropriate new forms.

Figure 5 – Custom New Form for Event Type 1

Figure 6 – Custom New form for Event Type 2

Repeat the same steps for the Edit and Display forms to complete the custom views.

Converting SharePoint 2007 list templates for SharePoint 2010

I’m hot on the heels of a SharePoint 2007 to 2010 migration project.  It had been decided not to upgrade, but to transition all of the content across and try and make better use of the document management features of SharePoint from scratch.

One of the first problems we discovered was for bringing across list libraries.  This was to be a simple task, simply save the list as a template, import into the new environment and it should just work. Unfortunately, I was greeted with an error along the lines of “version 3 templates are not supported in this version of the product“.

Searching for the error, I came across the answer in this blog post of Importing SharePoint 2007 list templates (STP) into SharePoint 2010.

Tom’s solution  worked great, but there was no way I could get general users to extract the list template, edit the XML and re-package.  So I wrote this small PowerShell script:

#Script: UpgradeSharePointList#Author: Peter Heydon (www.heyweb.net)#Date: 16 September 2010#Purpose: This script will convert a SharePoint 2007 list template to be SharePoint 2010 compatible.##Credit for defining the conversion process: http://tom-dw.blogspot.com/2010/06/importing-sharepoint-2007-list.html#Credit for calling 7-Zip from Powershell: http://mats.gardstad.se/matscodemix/2009/02/05/calling-7-zip-from-powershell/#Everything else cobbled together from Microsoft TechNet##Requirements:# Three folders: input (SharePoint 2007 list templates)# output (SharePoint 2010 compatible list templates)# processed (SharePoint 2007 list templates that have been processed)# 7z.exe (from 7-Zip installation: http://www.7-zip.org/)# makecab.exe (should be in your WINDOWS installation folder)##WARNINGS: There is zero error handling, so don't expect the script to be gracefull. The script is supplied# 'as is' and should be tested thoroughly before using in a production environment.

### DEFINITIONS$RootDir = "\\server\share\path\" #Ensure it has a trailing backslash ('\')Set-Alias sz ("C:\path\to\7zip\7z.exe")
Set-Alias mcab ("C:\windows\system32\makecab.exe")

# Get list of all STP files$InputDir = get-childitem ($RootDir + "input")

foreach ($item in $InputDir | where {$_.extension -eq ".stp"})
{
$targetFile = ($RootDir + "input\" +$item.name)
$extractPath = $targetFile.substring(0,$targetFile.length-4)

"Processing: " + $targetFile
#Create directory New-Item $extractPath -type directory

#Expand STP File $extractPathOption = ("-o" + $extractPath)
sz x $extractPathOption $targetFile
#Replace files $manifestFileIn = $extractPath + "\manifest.xml" $manifestFileOut = $extractPath + "\manifestOut.xml" (Get-Content $manifestFileIn | Foreach-Object {$_ -replace "<ProductVersion>3</ProductVersion>", "<ProductVersion>4</ProductVersion>"} | Set-Content $manifestFileOut)

#Cleanup files Remove-Item $manifestFileIn Rename-Item $manifestFileOut $manifestFileIn
#Recompress (MakeCab) $itemNoExtension = $item.name.substring(0,$item.name.length-4)
$CabFileName = ($RootDir + "\output\" + $itemNoExtension + ".cab")
$NewSTPFileName = ($RootDir + "\output\" + $itemNoExtension + ".stp")
mcab $manifestFileIn $CabFileName
#Rename cab, and move to output folder Rename-Item $CabFileName $NewSTPFileName Remove-Item $manifestFileIn Remove-Item $extractPath
#Move original file to processed folder Move-Item $targetFile ($RootDir + 'processed')

}

I have a scheduled task now running every 10 minutes during the day that will process all files in the input folder.  The process is simplified, I’m not having to get involved, so everyone is happy!

Multiple Upload File Programmatically Using GridView

This is how to upload multiple file in SharePoint 2010. When user clicks upload button, the uploaded files will be put in windows temporary folder and listed in GridView. When user clicks submit button then the files will be send to SharePoint library. Refer to this solution from Mohan.

Uploading multiple attachments to the lists using JSOM

Uploading multiple attachments to the lists using JSOM

In the previous blog post, we have seen how to attach a single file to the list item

In this blog post we will see how we can attach multiple attachments to a list item using JSOM. The following code will work in both SharePoint hosted apps and regular SPO web applications

The following technologies are referred/used in  the blog post

1. jquery.multifile.js
2. jquery
3. SPO client side libraries

Not much information is available in the internet to attach multiple files to the list items.

In your custom form, where you want to attach multiple files, add the following html tags which will facilitate the user to attach multiple files to the list item

As part of this post, we assume that, we have list called "MyList" and in that list we have two list columns called "FirstName" and "LastName"

When we insert data to this list, we also attach multiple list items. The below code snippet will show the simple html that has been created for the user to insert data into the list called "MyList"

	<div class="fld">
	<div>
	<span>First Name</span>
	<span><input type="text" id="txtFirstName"></span>
	</div>
	<div>
	<span>Last Name</span>
	<span><input type="text" id="txtLastName"></span>
	</div>
	Attach any relevant files
	<div class="files" id="attachFilesContainer">
	<input id="infringementFiles" type="file" class="multi browsebtn" />
	</div>
	</div>
	<div class="fld">
	<input class="btn" id="btnSubmit" value="Submit" type="button" />
	</div>

As you can see in the above code snippet, I have two html text boxes for FirstName and LastName and a file input control.

To facilitate multi file upload control, I am leveraging "jquery.multifile.js" plugin. If we don't use that plugin, the user will select only one input file for upload

When the user selects multiple files, here is how the UI looks like

 

As you can, with the help of jquery plug in, we can select multiple files. The complete UI will look like this

I also have a submit button and on click of that button, I want to insert a new list item as well as attach as the files that user has selected

On click of btnSubmit, all the files that are selected by the user will be attached to the list item.

Here is the code snippet for the btnSubmit click event. I have written this click event in the jquery document load function

	$(function () {
	var fileCountCheck = 0;
	$("#btnSubmit").click(function () {
	var data = [];
	var fileArray = [];
	$("#attachFilesContainer input:file").each(function () {
	if ($(this)[0].files[0]) {
	fileArray.push({ "Attachment": $(this)[0].files[0] });
	}
	});
	data.push({"FirstName": $("#txtFirstName").val().trim(), "LastName": $("#txtLastName").val().trim(), "Files": fileArray});
	createItemWithAttachments("MyList", data).then(
	function(){
	alert('Item created with Multiple attachments');
	},
	function(sender, args){
	console.log('Error occured' + args.get_message());
	}
	);
	});
	.....
	});

As a first step, loop all the attachments the user as selected and push that information into some javascript array. That javascript array function will just have the file information and not the contents of that file

	$("#attachFilesContainer input:file").each(function () {
	if ($(this)[0].files[0]) {
	fileArray.push({ "Attachment": $(this)[0].files[0] });
	}
	});

view raw FileArray.js hosted with ❤ by GitHub

Create another JSON array, to hold all the values the user has entered such as first name, last name etc. and including the file array that has been created above

data.push({"FirstName": $("#txtFirstName").val().trim(), "LastName": $("#txtLastName").val().trim(), "Files": fileArray});

After this, I have written some function will insert list item also attach the list items also

	var createItemWithAttachments = function(listName, listValues){
	var fileCountCheck = 0;
	var fileNames;
	var context = new SP.ClientContext.get_current();
	var dfd = $.Deferred();
	var targetList = context.get_web().get_lists().getByTitle(listName);
	context.load(targetList);
	var itemCreateInfo = new SP.ListItemCreationInformation();
	var listItem = targetList.addItem(itemCreateInfo);
	listItem.set_item("FirstName", listValues[0].FirstName);
	listItem.set_item("LastName", listValues[0].LastName);
	listItem.update();
	context.executeQueryAsync(
	function () {
	var id = listItem.get_id();
	if (listValues[0].Files.length != 0) {
	if (fileCountCheck <= listValues[0].Files.length - 1) {
	loopFileUpload(listName, id, listValues, fileCountCheck).then(
	function () {
	},
	function (sender, args) {
	console.log("Error uploading");
	dfd.reject(sender, args);
	}
	);
	}
	}
	else {
	dfd.resolve(fileCountCheck);
	}
	},
	function(sender, args){
	console.log('Error occured' + args.get_message());
	}
	);
	return dfd.promise();
	}

I am using regular JSOM code for creating the list items. Since attachments has to be inserted  to the newly created item, I need to know the ID to which I need to insert the attachments

So, first I will insert/create the data, get the list id and to that list id, we need to insert attachments


After the getting the list id, I will loop with all the attachments the user has selected. I wont resolve the function, till I insert all the list attachments. If all the attachments are inserted, I will resolve the function

loopFileUpload function need to called recursively till all the list attachments are inserted

	function loopFileUpload(listName, id, listValues, fileCountCheck) {
	var dfd = $.Deferred();

As you can see in the above function, loopFileUpload has been called recursively till all the list attachments are inserted

With in the loopFileUpload function, I am calling another function called uploadFile which will associate the list attachment to the id that has been passed to that function



Within the uploadFile function, I am calling another function called, getFileBuffer, will will read the actual contents of the file and pass that information to uploadFile function

We are using REST based approach for inserting the list attachments as REST will allow to upload upto 2 GB of file

Here is the url that needs to be used to access the list item id to which we need to insert the list attachment

spPageContextInfo.webServerRelativeUrl + "/_api/web/lists/GetByTitle('" + listName + "')/items(" + id + ")/AttachmentFiles/add(FileName='" + file.name + "')",
