However, that is a trap for young players. The datagridview displays multiple rows. NET component for.I've been working on a Windows Form Application that displays continuously updated data from an external source in a tabular format.

Here's a brief? Let's call this class Stock, with only two elements, Ticker and Price. My app is connected to another piece of software that pushes data to it at random intervals. The data is pushed in a similar format to my Class, in that when the data feed event is triggered it provides me with a struct containing Ticker and Price. This information needs to be displayed real-time in a datagridview in the main Form, and this table needs to be sortable.

The admittedly awful way I'm handing all this currently is as follows I'm not a programmer by trade so this is surely a big hack : - I store my collection of instances of the Stock class in an array.

When the user sorts a column, I rebuild the Row Hashtable so that any new information coming in goes to the proper row. This all works fine, with some odd quirks mainly pertaining to the two hashtables, probably. I've since discovered that using a Bindinglist as my collection of objects and binding the Datagridview to it will allow me to have any changes to the object elements be automatically updated in the Grid using INotifyPropertyChanged.

This works fine, but the grid is now no longer sortable. So I've found a way to make a sortable BindingList, but now I have another problem that the BindingList's indexes change when the list is sorted. How do I quickly search through a BindingList of objects' elements to determine the new location? I never have more than objects in the list, so I could loop through them, but I can get hundreds of external updates per second and I'm not sure if that will become a problem.

Finally, another option is using a Datatable instead of a BindingList. This allows me to not have to update the grid directly, but just update the underlying Datatable which is reflected in the Form's grid, and fixes the sorting problem: Row 0 is always Row 0 no matter how it's sorted.

However, I don't know how to relate my Ticker object to a DataRow. I assume I would still have to have my objects in some type of collection, then when I update the object, I would then also have to update the relevant DataRow in the Datatable - back to using another hashtable.

This post is a bit disjointed, I suspect using the BindingList is the best option, but perhaps someone can point me in the right direction I already posted regarding this on SA, but I think I have more detail to work with here and less noise since this is a specific thread for this question.

At least, the impression I get is that the data you receive allows you to make updates based on lookups in this fashion. This is a pretty terrible mashup of data collections, but it seems like you have: a. An array of Objects b. I would have a separate thread for the data interface that collects updates from the data source and puts them on a thread safe queue. I would also have an update thread running every ms or so that gets everything from the queue, then loops over the updates and finds the corresponding object in the List using most likely the.

The update thread would lock the user interface so that you can't corrupt the view state while doing an update you don't mention whether this is read only, but if the user scrolls around while an update is happening, you could have contention on an object property value between the screen refresh and the update thread.

If you get a good handle on the virtual mode, this is probably the cleanest way to present the data in the gridview because virtual mode allows you to use the collection you're storing the objects in for the cell values.

Simple update to existing code: If you're using a binding list, the main thing you want to get away from is that array. You're introducing an extra mapping that causes you to lose synchronization. One assumes that you should be able to look up your object from the binding list based directly on the 'Ticker' value without having to go through that additional step unless I'm missing information somewhere, not sure how perfect your analogy is.

In that case, the main thing to look out for is locking state. I'm not sure whether your updates are coming on the main GUI thread or not, so you have to be careful that you don't try to change the collection while something else is trying to use it. I'm not entirely certain whether VB.
