Getting error while adding field to data viewer web part

Posted By:      Posted Date: October 22, 2010    Points: 0   Category :SharePoint

I have custom EditItemForm for a custom list having over 100 columns. That EditItemForm contains a DataFormWebPart in edit mode having over 100 <SharePoint:FormField controls.


If I browse for the above page in internet explorer, I got got the generic error:


"Unable to display this Web Part. To troubleshoot the problem, open this Web page in a Microsoft SharePoint Foundation-compatible HTML editor such as Microsoft SharePoint Designer. If the problem persists, contact your Web server administrator.

Adding a web part to "My Content" page causes error

Under a "My Content" personal page, a user (me) chose to add the "SQL Server Reporting Services Report Viewer" web part to a page. This was repeated with a test account and the same thing happened. Is there a way to fix this? Prior to this, adding a Content Editor Web Part seemed to work just fine.

After adding filter, data fetch limit error


Alright, so i'm getting the "this page has exceeded its data fetch limit for connected web parts" error.
But it only happens if i add a filter.

Currently I have 6 lists on the page and am using 4 filters, so why can't I add a 5th filter?

Data View Web Part, update to Data Source / adding new list to existing data source


Hi all,

I have four Lists with identical columns :

List 1
List 2
List 3
List 4

I had to merge them, hence i created a data source ( Linked Source ) and merged these lists in SPD. I have used a data view webpart to display some columns from the merged lists data source and everything was working fine.

But now i have a new List : List 5 which also has the same columns like the other four lists and i need to update the data soure such that it is merged list of 5 lists not 4.

i updated the datasource property of the linked source to merge this new list as well. However the contents of List 5 dont appear in the data view webpart. 

Am i missing something here ? 

I dont want recreate the data view web part from scratch eachtime , because in future there might be List 6 , List 7 as well ... 

Business Data List web part, format field from database as hyperlink


I have a BDC with an entity that selects fields from a table. One of the fields is the full pathname to a file, or it could be a hyperlink.
When I display the entity in a Business Data List Web Part, all fields are displayed as text, without any formatting. I know the formatting can be modified using the XSL editor (under modify web part), I have found a sample with date-time format . Some basic formatting can also be done with de sharePoint designer, but nowhere have I found an example that allows me to format the column with the link as a clickable hyperlink.
My strong points are sql server and .net , but not XSL , can anyone give me an example of how th eformatting needs to be done in XSL?

tnx in advance

Filter Data View Web Part based on a field



I am trying to filter a data view web part based on a choice made by the end user. I have a lookup field in the Pages list that displays the Title of all pages within that list. I want it so that when an end user selects something from that field that it will filter the list accordingly. Do I need to create a variable, parameter or something of that nature?

Any help is greatly appreciated! Thanks in advance.


Data Form Web Part - Sharepoint Dropdown List as a field in Edit View - Possible?


Hi guys,

I'm building a Sharepoint page with a data form web part that uses custom SELECT and UPDATE statements with an SQL Server connection in order to retrieve and store records of information.

I'm getting along fine, records seem to update how they should etc, but I've ran into a problem with one thing: Sharepoint dropdownlists in 'Edit Template'

So the issue is this: if I replace a textbox field with a dropdown list that is populated with a separate SQL datasource, the dropdown list seems to be unable to show the current value of the field.

E.g. I have a dataview which has a field "FruitID", which I can update just fine by setting the ID value to different numbers. The SQL datasource uses the FruitID to display a list of all available Fruits, (e.g. 1 = Banana, 2 = Apple, 3 = Cherry, etc).

If i open the dataview in editmode, the default value in the dropdown is null, despite the real value of the field being "2", which should show "Apple" in the dropdown.

I can select a fruit and click save, and it will update just fine. But the initial display needs to show the correct value to start with.

Is there a custom binding I should be coding to make this work? I can't configure dropdown <items> on an individual level as they are populated from the SQL server. I can't set "SelectedI

Error while adding 3rd node to a cluster --- Failed to retrieve data for this request.


Inside a virtual environment running Windows 2008r2 Ent SP1 and SQL 2008r2 RTM.

Inintial cluster build has gone smoothly for a 2 node cluster using iSCSI. Added up a third node to this cluster manually changed quorum model and MsDTC resource was bouncing all well on the three nodes. Sweat started when the third node failed to add into SQL Failover cluster with the given message "Failed to retrieve data for this request" right after clicking add a node.

Sites talk about adding CuP6 and to lower the security but to note all this worked for first & when adding second node, for the moment this was resolved for me after I restarted all the nodes; going from Node3 to 1. For a moment RemoteRegistry service failed to start on node2 and it wount work even on restarts so moved every thing to node1 now the RPC was up on Node2 and I can go further on adding node3 to SQL cluster but as I'm typing it failed again.

As I check the logs they point about failures to write to registry and at time Network Path not found, User credentials used are all same and pings are going well for the entrire set of IP's I have.

Any insights on this are highly appreciated?

Data Points: The Enterprise Library Data Access Application Block, Part 3


E nterprise applications can have a wide variety of data update requirements. Sometimes you need to save multiple rows of changes at once within a single transaction. Other times, the user must be allowed to enter multiple rows of data, send them to the database in a batch; and if a row or two fails, only the rows that succeeded should be committed and remain committed.
