Update a field in a gridview to False on a Button Click

 Hi, Ive got a list of records in a gridview (from an SQLDataSource) where a field value is set to True.  I've also added a "reset" button in a template field at the start of the row in the Gridview. What I would like to do is allow the user to click the reset button on a particular row and 'reset' the true value to 'false' (updating the source data). Are there any idiot proof tutorials to do this??? Many thanks for your help! Fiorano

How do you update a Lookup Field from CAML by Name rather than ID

Hi, I have the following batch update in my code: xml += "<Method ID='" + currentID + "' Cmd='Update'>"; xml +=   "<Field Name='ID'>" + ID + "</Field>"; xml +=   "<Field Name='FileRef'>" + fileRef + "</Field>"; xml +=   "<Field Name='Title'>" + doc.NewFileName + "</Field>"; xml += "<Field Name='Keywords'>" + doc.Keywords + "</Field>"; xml +=   "<Field Name='Select_x0020_Type'>" + ((doc.TypeName == "General") ? 1 : 2) + "</Field>"; xml +=   "<Field Name='Population'>" + "Demography" + "</Field>"; xml += "</Method>"; The Population field is a lookup. It works if I put the ID of the ListItem in there, but not if I put the name - I need to put the name in. Can anyone help? Thanks. John.  

Update an accumlating shapshot fact table

This is my first time implmenting an accumulating snapshot fact table and I require some guidance. Accumulating snapshot fact tables show the status at any given moment. It is useful to track items with certain life time, for example: status of order lines.eg everytime there is new piece of information about a particular purchase, we update the fact table record. We only insert a new record in the fact table when there is a new purchase requisition. What I really need to know is how best to handle the updates.  This really feels very similar to managing SCD-1's in dimension processing! Anyone able to advise? thanks in advance Here is a perfect example we can use  http://blog.oaktonsoftware.com/2007/03/accumulating-snapshot-use-accumulating.html Figure 1, below, shows an accumulating snapshot for the mortgage application process. The grain of this fact table is an application. Each application will be represented by a single row in the fact table. The major milestones are represented by multiple foreign key references to the Day dimension—the date of submission, the date approved by mortgage officer, the date all supporting documentation was complete, the date approved by an underwriter, and the date of closing.

Can I update Project Field value via some javascript?

Hi there, I've a webpart that's designed to update some project field value, this webpart is  located on a Project Details Pages. On this project details page, there is another MS Build-in webpart call Project Field webpart. Now when I clicked the Save ribbon button, the project field webpart will raise some client calls, at the same time my custom webpart will raise a post-back(update value via PSI) call which will kill the client calls..So is it possible for me update the project filed value via some javascript? so I'll no longer raise a postback. Or is it possible for me to capture the client calls event for MS webpart, then I can fired my own PSI code? Thank you,   Regards, Joe

importing table with Access "memo" field to SQL

I imported an access database using the DTS wizard, into SQL 2005. There is a field in one of the Access tables that is a memo field, filled with a bunch of text including linebreaks. After importing, the field is indicated as the nvarchar(MAX) datatype when I check in SQL Enterprise Manager. The text in that field is displayed without line breaks, both in EM and when viewed on a web page. I changed the datatype of that column to "text" and now can see line breaks when I hover over a value in that column while viewing the table data in Visual Studio 2010's Server Explorer.But when I display the data in a ListView, there are no linebreaks. When I view my TableAdapter in my dataset, there are no linebreaks either.I must be missing something here? Thanks.
