Hi all, I am fresh new to asp.net.  I try to convert my windows form into asp.net application. On my Windows form I use threads to monitor for changes in data sources to udpate my controls. However, I got no clue how to accomplish this in asp.net form.  It seems I cannot create a thread in the page to update my controls in the page.  I realy appreciate for any comments   Thanks

Infopath form - browser error client error

  

I am facing a problem with browser enabled infopath form. I have developed this in infopath 2007. I have few fields in a repeating table. It contains Number of units, qty , subtotal and total. Total is sum of all sub totals and Sub total is  multiplication of units and qty. I am able to insert new items in preview and getting subtotal and total. I have published it in sharepiont as browser enabled form as a content type. When I opened the form in browser and insert new item in repeating table then I am not getting my subtotal and total updated. I am getting those for only first row. other rows are not working. This is working with infopath client.  Please help me out..

Using ajax to submit and update form

  

Hi all,

  I'm new to ajax and not sure if it's necessarily the technology I need to accompolish what I'm looking to do. What I'd like to have is a simple two textbox and button form that let's the user submit some credentials (not for logging in) but instead to verify their identity for other purposes.  I would label the button as "Continue" and assuming it passes through, the form would update with some new data entry controls that would allow them to submit some final information.  I thought perhaps ajax would be a nice way to do this since I wouldn't need to create a second continuation page from the first to display a new form.  However, I'm unsure how it's possible to update the form in the first place to look different.  Or is there perhaps a cleaner way to do this?  Any help would be appreciated.  Thanks


making page work after DB update in Form View

  
I could really use some help with this issue. I have a DropDown that allows the selection of a Category Code. The selection populates a Gridview with details of records matching the Category Code. I have only enabled the Select option on the Gridview, which when clicked populates a Formview in Edit Mode with the full record information. When editing is complete and the Update link is clicked, I can not get the page to properly reload/postback. When another Category Code is selected from the Drop Down the Gridview does not report a list of records.   Any help would be greatly appreciated.   Thanks,              

How to prevent automatic update from sharepoint list on Infopath 2007 form

  
Hi there, I've got an Infopath 2007 form on MOSS 2007. I have a custom list in sharepoint and the infopath form has a data connection to that list to receive data. Is there any way to prevent automatic update on the values in the form that is received from the list. I'd like the new form to have updated info received from the list. However, the old/existing forms that were created should have the data that were available at the time when the form was created. Let me know if this is not clear and I'll try to explain more. Thanks,Pman http://www.pmansLab.com/

Client Object Model - update metadata

  
Is there a way that I can update the metadata for a document in a document list using a UniqueId without having to speciify the library name? If I know the library name and the ID I know how to update the metadata but what I was hoping was that there would be a way of doing it using a UniqueId without knowing exactly which Library the document is in.

Efficiently get all client form data for manipulating duuring raisecallback

  
Hi, I'm trying to get most of the data I have on my web page, to update a query during an asp 2.0 raisecallback event. I've tried Request.Form with no luck. I've got the html (sent in raisecallback parameter) using 2 div tag's innerhtml. Can someone tell me an efficient method to use to get all this data for updating - Do I have to parse from the callback string (eventArgument) & if so can I use a reader of somekind, or is there a better way? Please provide example & thanks in advance for any help!!

Client Object Model : Transactional update of list and content types

  
I am using Silverlight client object model to code against Sharepoint. Essentially, what I want is that when a user clicks a button, An item needs to be added to a list and also a new content type has to be created. button1_click() { //1. Create an item in a list. //2.  Create a new content type. } Also this should be transactional:  only if item is added should the content type be added too, otherwise roll back both. (and vice-versa). My understanding of client object model is that we at the core we are talking to Sharepoint WCF services. So if I say, using(TransactionScope scope = new TransactionScope()) { ClientContext.ExecuteQueryAsync(); scope.Complete(); } can I assume that the updation will be transactional??

Form opening in infopath client despite Content Type settings "Display as a Web Page"

  
Hi all,   I have a strange behavior with my forms. The infopath template is defined as Content Type for my Form library, in the advanced settings I have checked "Display as a Web page" for the "Opening browser-enabled documents" setting. Despite that when the client is availble on the computer which is browsing the Form Library, I'm asked to "Open", "Save" or "Cancel" instead of opening the form in the browser.   Any idea why this is happening ?

A potentially dangerous Request.Form value was detected from the client

  

I know this has been discussed already but my problem isn't the error itself. My problem is I am including [ValidateInput(false)] above my ActionResult and I still receive this error when I click submit. Is there something somewhere else overriding this command?


Here is what the code looks like.


[Authorize(Roles = "Administrator")]
        [HttpPost]
        [ValidateInput(false)]
        public ActionResult Create(FormCollection Form)
        {

[Authorize(Roles = "Administrator")]

        [HttpPost]
