Grid is a user interface component for displaying tabular data to the user, typically providing sorting and editing functionality, among others. Data. Grids have been the work horse of various frameworks such as ASP. NET Grid. View and Windows Forms Data. Grid. View. However, Data. Grids in WPF are rather conspicuous in their absenceIn my jcl,the 1st step is delete step, if the data set is existing, I want to delete, that one,if dataset is no existing, I do not want abound the job, how can I. Hi. I am new to vb. I am trying to retrieve a row from a SQL table, and. I have a BindingSource that is bound to a DataTable in a DataSet. How can I get a specific column value from the BindingSource and not from the controls For example. Update Dataset Column Value In Vb.Net' title='Update Dataset Column Value In Vb.Net' />Fortunately, the absence of this control has not hampered the popularity of WPF. The versatility of the List. View control allows very flexible read only Data. Grid functionality. Also, the lack of a Data. ASP. NET is a technology for developing, deploying, and running Web applications and it is a part of the Microsoft. NET Framework. Grid within the WPF APIs was an excellent opportunity for third party component providers see Michael Syncs blog for a roundup of the five leading third party WPF Data. Grids. Eventually, in August 2. Microsoft released its Data. Grid CTP Community Technology Preview a public beta to Code. Plex to coincide with the release of the. NET Framework 3. 5 SP1 and Visual Studio 2. SP1. The. NET Service Packs provided additional WPF functions including IEditable. Collection. View, Binding. Group, and alternating row styles which are all used within the WPF Data. Grid. Another small yet very highly welcome feature of SP1 is the Binding. String. Format which provides a simple mechanism for formatting bound data, as described in this blog post. More recently, on October 2. Data. Grid v. 1 was released. This is the last update that we will see of the Data. Grid before. NET 4. Currently, there is a lack of documentation and examples demonstrating common Data. Grid usage scenarios which is to be expected, as it is an out of band release. This article provides a number of simple usage examples which will hopefully be of use to anyone considering using the WPF Data. Grid. I cannot, of course, cover everything. If you are having problems with making the Data. Grid do what you want, post a comment at the bottom of this article, and I will do my best to help. The WPF Data. Grid is part of the WPF Toolkit. The steps to add the Data. Grid control to your project are as follows Install the. NET Framework 3. 5 SP1. Download the WPF Toolkit either source or binaries the toolkit is entirely open source. Run WPFToolkit. msi to install the WPFToolkit. WPF Toolkit design time binaries to your Program Files folder. Reference the WPFToolkit. Probably, one of the most frequent uses of a Data. Grid is to provide the user with CRUD functions create, read, update, delete for managing a persistent data source. This example describes how to connect a Typed Data. Set to the Data. Grid in such a way that row modifications, deletions, and insertions are written to the database. For this example, and the others in this article, I am using the ubiquitous Northwind database. Details of how to download it for SQL Express are given in the MSDN library. The Data. Set design for these examples was created via simple drag and drop from the Server Explorer. For a thorough Data. Set tutorial, I would recommend this Data Access Layer tutorial. The simplest method for displaying the Customers table within the WPF Data. Grid is to add the control to our window as shown below. Note the addition of the http schemas. Windowx ClassWPFData. Grid. Examples. Data. Set. CRUDExamplexmlnshttp schemas.

Default. View. The resulting window will contain a grid which displays all the columns of the Customers table, thanks to the Auto. Generate. Columns property of the Data. Grid which defaults to true. This works well enough however, one of the advertised features of the WPF Data. Grid is design time support. If you right click on the Data. Grid in the Visual Studio designer, you will see a Data. Grid entry in the context menu. However, the sub menu is a little sparse, and displays the message You need to set Items. Source to enable some column operations. The problem is that the Data. Grid designer is unable to inspect the contents of the Items. Source property of the Data. Grid if it has been constructed in the code behind. An alternative method for providing data to your controls is through the use of an Object. Data. Provider. This class enables you to instantiate an object within your XAML resources for use as a data source. You can then invoke methods on this class in order to provide data to your controls. This method yields a few extra benefits which are described in Beatriz Stollnitzs blog. The following class effectively performs the same dataset population steps as above publicclass Customer. Data. Provider. private Customers. Table. Adapter adapter. Northwind. Data. Set dataset. Customer. Data. Provider. Northwind. Data. Set. Customers. Table. Adapter. adapter. Filldataset. Customers. Data.

Grid is now available, allowing you to configure which columns are present, their bindings, sorting, etc. This design time support is certainly nice to have however, it is very easily missed as it inserts a single menu option into an existing context menu. The WPF designer Cider does not follow the conventions of the Windows Forms and ASP. NET designers which indicate that a control has design time support by the presence of a small button in the top right corner. When the user edits the Customers data within the Data. Grid, the bound in memory Data. Table is updated accordingly. However, these updates are not automatically written back to the database. It is up to the developer to decide when changes to the Data. Table are written back to the database depending on the requirements of the application. For example, in some cases, you might wish to submit a batch of changes via a Submit button, or you may wish to have the database updated as the user commits each row edit. In order to support these, the rows that the Data. Table contains have a Row. State property which indicates whether they contain changes which should be synchronized with the database. The synchronization process is easily achieved via the Table. Adapters Update method. The following example shows how the Row. Changed and Row. Deleted events can be handled so that changes in the Data. Table state are written to the database each time the user changes a row public Customer.
