Hello,

I’m Jijo George and working ad Software Engineer in Bangalore. I am new to VS 2008. Actually I need to create one custom control, which i have to use in the entire application and some other application too, which contains a dropdownlist and a textbox. Whenever the data binds happens, the dropdownlist should add one more row ‘new row’. And when the user selects on this item, the dropdown should be invisible and the text box should be visible. Then the user can add a new value in the textbox. and when the user press enter key, the new value shoul add to the dropdownlist, if the value is not the in the list. This is something called an editable(only one row), dropdownlist. The coding has completed but unfortunately i created an .ascx file. So need to include this file in all application wherever i need to use. So I thought of creating a custom control and add to the tools box, where i got stuck. So could you provide the steps to create a custom control with the above mentioned criteria.

Thanks in advance,
Jijo George.

Hello Dhaval i recently came across signalR …i searched across the net but hardly found any tutorials which taught the concept from scratch… yours was very helpful.though i have one query that is whether i can work with signalR in vs2008.

SignalR’s different versions had dependency on dotnet framework. Older signalr beta used to support 3.5.
Latest signalr Hubs makes extensive use of C#’s dynamic’s. So i would suggest to use .net 4.0 and above.

Hi Dhaval,
I’ve just learnt abouySignalR and your SRChat is quite amazing and has helped me a lot! I had a question though – Can you please tell me how I can send an automated message from the server to a specific client who sends a message on a browser and not to all the connected clients?

The older version which my post used you can do that using
Clients[Context.ConnectionId].youClientMethodName(arg1,arg2)

Suggest you to use the latest signalr version. In latest version you can do that using
Clients.Caller.youClientMethodName(arg1,arg2)
Refer

Check your Global.asax file. It should hookup start events appropriately

Hi Dhaval,

I have gone through your article.

https://dhavalupadhyaya.wordpress.com/tag/timercallback-function-example-in-net/

My code works well if I am logged on to application but when I am not logged on it does not work.

I need to schedule a job in midnight , so do you have any ideas why Timer does not work when we are not logged on to the application.

I have checked ‘App Pool Recycle Time’ set to 1740 minutes.

Your help would be of great help to me.

Thanks in advance for your help.

Regards,
Feroz.

Make sure you start the scheduler as depicted in Application_Start event of Global.asax file. Incase if the APP pool restarts\recovers by its own than with the first request will reinitiate the global.asax file and your timer will be hooked again.

If you are using IIS7.0 or above than to avoid waiting till first request you may like to configure loading options that can initiate loading of data. This can be done using the startMode attribute in the ApplicationHost.config file. You can even specify a custom action to run on start-up.

Thanks for the response Dhavan…. I have applied a different solution…. by making Idle Time for App Pool 1440 minutes (by default 60 mins)….

My case is that…. if you use the website at least once in a day overnight job should run which is not possible without keeping App Pool domain alive… and this is achieved by setting App Pool Idle time to 24 hours….

Should you feel this may cause any issue, please let me know… For the last one week I did not see any performance gap…
