Blog : Using Today Calculation in SharePoint 2010
I came across a requirement where we need to show/update a SharePoint column with today’s calculation depending upon another date
e.g.
There three columns like below :
- Status (Red, Green, Yellow)
- Targeted Completion date
The status column need to update AUTOMATICALLY if
Green = Targeted Completion date >=7 days
Yellow = Targeted Completion date <=7 days
Red = Targeted Completion date <=0 days
As there is no EVENT to be fired, there is no way out to update through workflow or any other event. Calculated column (Today trick) is not working successfully. So, I found creating a custom timer job will be a real solution.
I think many of our friends may be facing this issue, when I googled it, I unfortunately didn’t find a perfect solution, so thought of sharing my efforts.
Here you go :
1. The source code will be like below
2. I am using VS 2010
3. Copy the source code below
3.1 Create a feature
3.2 Create a class file to include the logic
4. Change the server name and list name with your server address and list address
5. deploy it to the server
5.1 Go to Central Admin --> Click on Review Timer Job Definition à Search your timer job à click on it to view the detail
5.2 if you want to run the timer job NOW à Click on the “Run Now”
You should be good to go now.
Few Tricks :
Issue : First time when I deploy the timer jobs it is working fine, but when I updated the code and redeployed the change does not reflect. Due to high cache management system, in MSS 2010. Sometime it does not update the actual change you did. For that you need to do the below :
Go to the services (services.msc)
Restart the Service “SharePoint 2010 Timer”, you should be good now.
For any issue / clarification you may contact me :
