BACKGROUND:
We’re developing a custom application which access SharePoint through the Client Object Model and this application need to access ECT (external content type) lists defined in SharePoint using the OM (Object Model). This application is a product that should be usable with most SharePoint installations and configuration and cannot have prior knowledge of External Lists.
When there are no filters set up for the ECT, SharePoint returns all the available items in the list (given the number is below the threshold). The moment we define a filter for this ECT, SharePoint return only the items after this filter is applied (probably correct behaviour from SP).
PROBLEM:
We need to be able to search this ECT list (non-filtered) based on text entered by a user in a search box. At the moment there seem to be no way to change the filter SharePoint applied when returning the values to the calling object.
I.e. I have 10 items in my ECT list (1,2,3…10). Each Item has 3 columns (ID, Name, Description). After setting up a filter for the ECT list, SharePoint return items 2, 3 & 6 when I ask SharePoint for a list of items.
No the user does a search the matches the description of item 7. How can I search/filter the list to return the item that match my search query?
I’ve been running in circles trying to solve this, but nothing seem to work. I tried setting the CAML query as well as the LoadQuery as defined in both http://pholpar.wordpress.com/2011/02/09/how-to-query-external-lists-on-the-client-side-using-caml/ and http://msdn.microsoft.com/en-us/library/ff464384.aspx but nothing seem to work.
Even I had this problem. Let me tell you there is no way of doing this.
Even in Server object model, there was an option to change the filters of the default view but then the SPList will return 0 items once the filter is applied.
The funny part is once your code runs & you open the list in SP UI, you can see the actual modified list. But the same cannot be queries in the object model.
Looks strange. I guess if you modify the SPList (ECT based) in this instance, then you can only get results in the next instance (like in next page refresh.....)

Is it possible to attach details from one sharepoint list to another like vlookup in excel? For example if I type unique index in one field, all details will be import from another sharepoint list. Any ideas how to do that? Can't find any solution.
You could use lookup column in the SharePoint list.
Reference: How to create a Lookup column in SharePoint
Sharepoint lists are not linkable like tables in relative databases. You could write a webpart or script or something else to 'connect' them.
You can use the APIs to get their contents and write a function which processes the contents. After processing you could use another API to write the results in another SharePoint List.
GET List_1 Data
GET List_2 Data
Process(List_1_data, List_2_data)
POST result to List_n
I’m not sure where to start on this project. I know how to read the contents of the excel spreadsheet, I know how to identify the header row, I know how to loop over the contents. I believe I have the UX portion worked out but I am not sure how to process the data.
I’ve googled and only found .Net solutions but I’m looking for a ColdFusion/Lucee solution.
I have a working form allowing me to map a user's spreasheet column to my database values (this is being kept simple for this post; user does not have direct access to the database).
Now that I have my data, I'm not sure how to loop over the data results. I believe there will be several loops (an outer and an inner). Then of course I also need to loop over the file contents but I think if I can get the headings mapped out,I can figure out the remaining.
Any good links, tutorials, or guides would be greatly appreciated.
Some pseudo code might be enough to get me started.
User uploads form
System reads headers and content.
User is presented form with a list of columns from their uploaded spreadsheet to match with available database fields (eg “column1” matches “customer name”.
User submits form.
Now what?
UPDATED
Here is what the data looks like AFTER the mapping has been done in my form. The column deliiter is the ::: and within the column the ||| indicates the ID associated with the selected column value. I've included the id and the column value since I plan on displaying the mapping again as a confirmation. Having the ID saves a trip to the database.
If I understand correctly, your question is: how do you provide the user a form allowing them to map their spreadsheet columns to that of the database
Since you have their spreadsheet column names, and you have the database column names, then this problem is essentially a UI/UX problem. You need to show both lists, and allow the user to map them. I can imagine several approaches to this. My first thought would be some sort of drag/drop operation, as follows:
Create a list of boxes, one for each field in your database table, and include the field name in (or above) the box. I'll call this the db field list. Then, create another list for each column from the spreadsheet, which I'll call the spreadsheet column list. The user would drag/drop items from the spreadsheet column list to the db field list.
When a mapping has been completed by the user, you would store the column/field names in as data for the DOM element of the db field list box. Then upon submission, you would acquire the mapping data by visiting each box and adding it to an array. Then you would serialize that array into JSON and send that to your form submission handler.
This could be difficult or easy, depending on your knowledge of UI implementations using JavaScript. jQuery makes this easy (if you know jQuery). There's even a jquery UI plugin that does this: https://jqueryui.com/droppable/.
A quick search for javascript drag drop would help, and here's a few articles I found:
https://www.w3schools.com/html/html5_draganddrop.asp
https://medium.com/quick-code/simple-javascript-drag-drop-d044d8c5bed5
You would also need to submit the array of mappings using javascript. You could search for that as well, and here's an article I found:
https://codereview.stackexchange.com/questions/94493/submit-an-array-as-an-html-form-value-using-javascript
I am fairly new to InfoPath and trying to create a form now that will link to the SharePoint list. Where I am stuck is that a lot of the steps online show you how to vlookup two fields (where one is a dropdown and another text box)But I need 2 fields to be a textbox field and connect them based on the sharepoint...so one text box field will automatically fill out info based on another Text box field..
So I have 2 infoPath fields:
a)Consumable Part number -> as a textbox - here user can manually enter the partnumber (I cant use dropdown here because we have circa 600 entries here!). All entries are stored in the sharepoint list in the Consumable Part Number column
b)Consumable Description -> as a textbox - here the field fills in automatically as soon as user enters the correct partnumber that indeed is available on this sharepoint list and each partnumber is linked to its unique Consumable Description. All entries are stored in the sharepoint list in the Consumable Part Number column
Is there anyway I could work around this please?
Thanks so much!
Add a data connection to the SharePoint List. Set the data connection to not run on form open - that is a checkbox in the last dialog box when you create the data connection.
On the text box where the user can enter a part number, add the following rules.
Rule condition - field bound to the text box for the user entered part number is not blank
Set a field's value - select the Part Number Query field from your SharePoint List data connection (be sure you pick the part number field in the "queryFields" folder)
Query for data - run the query to your SharePoint list
Set a field's value - set the field you want to have the description in to the returned data field Consumable Description in your SharePoint list data connection
Since you are querying based on the user entered part number, you should get back 0 or 1 item(s). You can add other rules to handle for the user entered number not being found (count of items returned in the SharePoint List data connection equals 0, you could display an error on the form, for example)
Edited to elaborate in light of additional comments:
The above technique sets a query field and returns items that match only that query field. If you have additional fields that dictate which list data should be returned, you'd set additional query fields.
If, instead, you need all items returned from the list and then you need to use XPath filters to determine which item you need from the list, you'd use the filter data button when picking the field that has the value you wish to use in your set value rule - from there you can add the various filters you need.
I'm afraid that I don't understand what you are attempting to achieve based on your comments.
What is the best way to implement a parent-child hierachy between items in a list? The requirement is as follows
-> there is a list item with a particular ID
-> that particular ID could have related records.
-> all those related records should show up when viewing the list item
When the user adds a new item to list using a form, they should have the option to choose whether the new item being added has another related item or not.
The primary question here is what would be the best way to establish this hierarchy in the list? Also, all the items would be in the same list so how
would we link the list to itself? Or, what would be the best way to implement this? I can figure out several approaches to handle this within the confines of the
sharepoint server object model; however, this needs to be done primarily within the UI of Sharepoint itself (webparts, features, etc. may be used). However,
I am not sure how to IMPLEMENT THIS WITHIN THE SHAREPOINT CONTAINER ITSELF.
Any ideas/insights would be greatly appreciated.
Thanks
You can create a look up column in list with a parent list as itself and allow multiple selections. That way you will be able to check multiple parent IDs for a specific list item.
To show related list items, you can customize details view page of the list in sharepoint designer and add list view web part or dataview with appropriate filters based on the current item.
I need a formula to calculate how much inventory is left on had after a work order has been completed. The work order I am developing is a separate list in sharepoint and I have an inventory list as well.
In the inventory list I have a field called amountinventoried and itemname which the user would put the amount of the item we had on hand during the last manual inventory.
On the work order list I have a field called itemused and amountused I need to find a formula to use on a calculated field in the Inventory list that would go out and simply subtract the amountused from the amountinventoried but only if the itemused and itemname fields matched.
I have been working on this for quite a while and have hit a wall, I'm probably overlooking something extremely easy but I'm still new to sharepoint 2010.
Thanks!
You may be able to do this in a grouped view of the work order list (sort of like this), but I think the design of what you are doing is not suited to using SharePoint lists.
You may be much better off using an SQL database to host and calculate the data and connect it into SharePoint as External Lists using the Business Connectivity Services (brief explanation here).
This gives you the benefit of CRUD functionality in SharePoint, with the extra calculations and trickery available within SQL views and tables.
