     Use blur event to track it. This is an event called, whenever the user leaves an element.

     suchfeld.blur(function() { if( suchfeld.val() == 0 ) { suchfeld.val("Suche..."); }});

     The opposide is focus, not click.

     $(function() { var suchfeld = $("#suchfeld");- // or suchfeld.focus(function() {}); suchfeld.on("focus", function() { if( suchfeld.val() == "Suche..." ) { suchfeld.val(""); } }); // or suchfeld.blur(function() {}); suchfeld.on("blur", function() { if( suchfeld.val() == 0 ) { suchfeld.val("Suche..."); } });});

     You can chain these too:

     $(function() { $("#suchfeld").focus(function() { if( suchfeld.val() == "Suche..." ) { suchfeld.val(""); } }) .blur(function() { if( suchfeld.val() == 0 ) { suchfeld.val("Suche..."); } });});

   • How do I remove/unregister event handler from an event?

     Top Answer

     Answered Sep 26, 2011 · 3 votes

     OK. I've been trying a lot of stuff to solve this but ChrisNTR came with the right solution to my particular problem. I will show his example snippet here:

     public override UITableViewCell GetCell (UITableView tableView, NSIndexPath indexPath){var cell = tableView.DequeueReusableCell("reuseThis");if(cell == null){cell = new UITableViewCell(UITableViewCellStyle.Default, "reuseThis");}cell.TextLabel.Text = Convert.ToChar(dash.oneToHundred[indexPath.Row]).ToString();var button = UIButton.FromType(UIButtonType.RoundedRect);button.Frame = new System.Drawing.RectangleF(40f, 0f, 280f, 40f);button.SetTitle(dash.oneToHundred[indexPath.Row].ToString(),UIControlState.Normal);button.AddTarget (this, new Selector ("MySelector"), UIControlEvent.TouchDown);button.Tag = indexPath.Row;cell.ContentView.AddSubview(button);return cell;}[Export ("MySelector")]void ButtonEventHere (UIButton button){Console.WriteLine ("Hello! - Button clicked = " + button.Tag );Console.WriteLine ( Convert.ToChar(dash.oneToHundred[button.Tag]).ToString() );}

     In short you call button.AddTarget() and you pass the corresponding values to the button. one of these values is the selector which you defined as 'buttonEventHere' (can be any name you want it to me my sure that the [export("MySelector")] has the right name). Make sure you pass the indexPath.Row to the button.Tag. You will use that index to know which button was pressed and do your action accordingly.

     Hope this helps if you was stuck as i was.

   • Event handling from inside an Async method

     Top Answer

     Answered Jan 22, 2014 · 0 votes

     I could not find any problem with the way I had set up the methods and events of the Zxing library. Especially after doing the same settings on MonoTounch and all worked fine. Thus, I went into the source code to see what does the scanner.Cancel() method does internally. I found that it just calls the Cancel() static method on the ZxingActivity, so I did that from my code and all seemed to work fine. This is probably not the most elegant solution, and I have reported an issue on the Zxing.Net.Mobile repo on github (here), but for now this works, and I hope it could help someone else too. I also have a full post detailing my experience with using this library on MonoDroid in case anybody needs it here.

     so the fix was replacing this line (from the above code):

     ZxingBarcodeScanner.Cancel();-

     with this line:

     ZxingActivity.RequestCancel(); -

   What are Event Hubs throughput units? (Standard tier)

   Throughput in Event Hubs defines the amount of data in mega bytes or the number (in thousands) of 1-KB events that ingress and egress through Event Hubs. This throughput is measured in throughput units (TUs). Purchase TUs before you can start using the Event Hubs service. You can explicitly select Event Hubs TUs either by using portal or Event Hubs Resource Manager templates.

   Do throughput units apply to all event hubs in a namespace?

   Yes, throughput units (TUs) apply to all event hubs in an Event Hubs namespace. It means that you purchase TUs at the namespace level and are shared among the event hubs under that namespace. Each TU entitles the namespace to the following capabilities: •Up to 1 MB per second of ingress events (events sent into an event hub), but no more than 1,000 ingress events, management operations, or control API calls per second. •Up to 2 MB per second of egress events (events consumed from an event hub), but no more than 4,096 egress events. •Up to 84 GB of event storage (enough for the default 1 hour retention period).

   How are throughput units billed?

   Throughput units (TUs) are billed on an hourly basis. The billing is based on the maximum number of units that was selected during the given hour.

   What is a dedicated cluster?

   Event Hubs Dedicated clusters offer single-tenant deployments for customers with most demanding requirements. This offering builds a capacity-based cluster that isn't bound by throughput units. It means that you could use the cluster to ingest and stream your data as dictated by the CPU and memory usage of the cluster. For more information, see Event Hubs Dedicated clusters.

   How do I create an Event Hubs Dedicated cluster?

   For step-by-step instructions and more information on setting up an Event Hubs dedicated cluster, see the Quickstart: Create a dedicated Event Hubs cluster using Azure portal.

   What can I achieve with a cluster?

   For an Event Hubs cluster, how much you can ingest and stream depends on various factors such as your producers, consumers, the rate at which you're ingesting and processing, and much more. The following table shows the benchmark results that we achieved during our testing a Legacy dedicated cluster: In the testing, the following criteria were used: •A dedicated-tier Event Hubs cluster with 4 capacity units (CUs) was used. •The event hub used for ingestion had 200 partitions. •The data that was ingested was received by two receiver applications receiving from all partitions.

   See full list on learn.microsoft.com

   How many partitions do I need?

   As partition is a data organization mechanism that allows you to publish and consume data in a parallel manner. We recommend that you balance scaling units (throughput units for the standard tier, processing units for the premium tier, or capacity units for the dedicated tier) and partitions to achieve optimal scale. In general, we recommend a maximum throughput of 1 MB/s per partition. Therefore, a rule of thumb for calculating the number of partitions would be to divide the maximum expected throughput by 1 MB/s. For example, if your use case requires 20 MB/s, we recommend that you choose at least 20 partitions to achieve the optimal throughput. However, if you have a model in which your application has an affinity to a particular partition, increasing the number of partitions isn't beneficial. For more information, see availability and consistency.

   Where can I find more pricing information?

   For complete information about Event Hubs pricing, see the Event Hubs pricing details.

   Is there a charge for retaining Event Hubs events for more than 24 hours?

   The Event Hubs Standard tier does allow message retention periods longer than 24 hours, for a maximum of seven days. If the size of the total number of stored events exceeds the storage allowance for the number of selected throughput units (84 GB per throughput unit), the size that exceeds the allowance is charged at the published Azure Blob storage rate. The storage allowance in each throughput unit covers all storage costs for retention periods of 24 hours even if the throughput unit is used up to the maximum ingress allowance.

   How is the Event Hubs storage size calculated and charged?

   The total size of all stored events, including any internal overhead for event headers or on disk storage structures in all event hubs, is measured throughout the day. At the end of the day, the peak storage size is calculated. The daily storage allowance is calculated based on the minimum number of throughput units that were selected during the day (each throughput unit provides an allowance of 84 GB). If the total size exceeds the calculated daily storage allowance, the excess storage is billed using Azure Blob storage rates (at the Locally Redundant Storage rate).

   Why am I not able to create a namespace after deleting it from another subscription?

   When you delete a namespace from a subscription, wait for 4 hours before recreating it with the same name in another subscription. Otherwise, you might receive the following error message: Namespace already exists.

   What are some of the exceptions generated by Event Hubs and their suggested actions?

   For a list of possible Event Hubs exceptions, see Exceptions overview.

   Diagnostic logs

   Event Hubs supports two types of diagnostics logs - Capture error logs and operational logs - both of which are represented in json and can be turned on through the Azure portal.

   How can I target a specific version of Azure Storage SDK when using Azure Blob Storage as a checkpoint store?

   If you run this code on Azure Stack Hub, you'll experience runtime errors unless you target a specific Storage API version. That's because the Event Hubs SDK uses the latest available Azure Storage API available in Azure that might not be available on your Azure Stack Hub platform. Azure Stack Hub might support a different version of Storage Blob SDK than that are typically available on Azure. If you're using Azure Blog Storage as a checkpoint store, check the supported Azure Storage API version for your Azure Stack Hub build and target that version in your code. For example, If you're running on Azure Stack Hub version 2005, the highest available version for the Storage service is version 2019-02-02. By default, the Event Hubs SDK client library uses the highest available version on Azure (2019-07-07 at the time of the release of the SDK). In this case, besides following steps in this section, you'll also need to add code to target the Storage service API version 2019-02-02. For an example of how to target a specific Storage API version, see the following samples for C#, Java, Python, and JavaScript/TypeScript. For an example of how to target a specific Storage API version from your code, see the following samples on GitHub: •.NET •Java •Python - Synchronous, Asynchronous •JavaScript and TypeScript
