Answer 1

You can drag and drop the assembly into the GAC.  The best solution would be to package this as a WSP.  Have a look at WSPBuilder http://www.codeplex.com/wspbuilder

There is a kickstart article for packaging a webpart as WSP using WSPBuilder http://rasor.wordpress.com/2008/10/12/wss-dev-quickstart/

What do you mean by user defined?  Who is the user (the developer or front-end user)?

Hi Siva,

       IF you are done wit the coding art, then do the following to deploy the webpart in the shareoint site.

            1. After buliding the roject with zero errors, Right click on the solution and go for -properties - Signing - Add a key name (your classname for easy reference).

           2. In password, uncheck the password option. and then save and build the solution once again.

           3. Open the folder where you have the solution At  bin- debug find the dll of the solution you made.

          4. Open the assembly folder at - Start - Run- type 'assembly' -Click  Enter.

         5. Drag and drop the dll file to the assembly folder.

          6. in the assembly folder - Right click - properties- find the version and the public key token-

          7. Add the  safe control tags with informations find above in the web.config file of the sharepoint site.

          8. Do an IISRESET and then open the site to find the webpart in the webpart gallery ( as said in the document)

Answer 7

Hi Siva,

While developing the WebPart, you must have created the *.webpart or *.dwp file.
Go to following path-
Site > Site Actions > Site Settings > Galleries > Web Parts > Web Part Gallery

Upload your *.webpart file there... now it will be visible in your Add Web Part pop-up.

Answer 9

You could create a dataview using SPD and use conditional formatting http://office.microsoft.com/en-us/sharepointdesigner/HA100996241033.aspx .  If you want to create a custom webpart and implement this you will need to set the css class on a row depending on some conditional logic.  I would suggest using SPGridView to display the information and on DataBound http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.webcontrols.spgridview.ondatabound.aspx set the css class depending on the data for that row.

Answer 11

Hi Siva,

        Verify whether your requirement matches out-of -box

       Verify the link below : http://pathtosharepoint.wordpress.com/ - Color Coding

         http://www.sharepoint-tips.com/2007/05/sharepoint-designer-article-2-creating.html

       You can also perform what you have asked for, showing a sharepoint list in a gridview.

       Access the site - list and add the columns in the list to gridview as bound column.

      Or you can simply get the data from the list using a caml query, extract the data using a getdatatable() function and the add to the gridview da datasouce..............

You will find n number of ways to do it via coding as well as SPD customization.
