ASP. NET Quick. Start Tutorials. The ASP. NET Grid. View control is the successor to the v. Data. Grid, adding the ability to take advantage of specific capabilities of ASP. NET data source controls. Whereas the v. 1. Data. Grid required a page developer to write custom code to handle simple operations such as paging, sorting, editing or deleting data, the Grid. View control can automatically handle these operations provided its bound data source control supports these capabilities. The Grid. View also offers some functionality improvements over the Data. Grid, such as the ability to define multiple primary key fields, and some UI customization improvements, such as new field types and templating options. It also exposes a new model for page developers to handle or cancel events. The following example demonstrates the Grid. View control bound to a Sql. Data. Source control to produce a read- only tabular report. In the preceding example, the Grid. View control reflected against the fields of the data records returned by Sql. Data. Source in order to dynamically generate the columns of the grid. You can also specify explicit column fields to display by adding Data. Gridview Templates In Asp Net GridviewControl. Field objects to the Grid. View's Columns collection. This allows you to specify exactly which columns to display and their relative order. The following example demonstrates a collection of Bound. Field and Check. Box. Field objects in the Grid. View Columns collection. Other field types that can be assigned to this collection are Image. Field, Hyper. Link. Field, Command. Field, Button. Field, and Template. Field. One of the key advantages of the Grid. View control over other data- bound controls is its ability to automatically take advantage of data source capabilities. Instead of relying on page code to manually sort or page data, the Grid. These tutorials demonstrate selected features in ASP.NET. ASP.NET Quickstart Tutorials. When performing updates or inserts with the GridView or. Asp.Net Gridview Css Templates This article doesnot explain the 'Hello World to Gridview'. If you are looking for that, you may look for Simple GridView walkthrough. While looping through the Rows of a GridView, you should not DataBind the GridView. So FillCustomerInGrid() should probably not be done. Checking GridView1.Rows.Count. GridView Examples for ASP.NET 2.0 GridView Examples for ASP.NET 2.0: Working with TemplateFields. GridView Examples for ASP.NET 2.0: Working with TemplateFields. View control can perform these operations automatically as long as the data source is configured to support these operations. The following example shows a Grid. View control with sorting enabled. You can also enable paging UI in the Grid. View by setting the Allow. Paging property to true. The Grid. View can automatically page over any return value from a data source that supports the ICollection interface. The Data. View returned by Sql. Data. Source when in Data. Set mode supports this interface, so Grid. View can page over the result. Gridview Templates In Asp Net TutorialsASP.NET GridView control demo. check your controls and rename them and set some basic properties of the GridView, such as GridView's templates and events. Dynamic Template Columns in the ASP.NET 2.0 GridView. add columns to the GridView dynamically using templates at runtime. A GridView template is a class that. In this interface's smart tag is a list of the templates in the GridView. added to the ASP.NET page's code. Using TemplateFields in the GridView. When in Data. Reader mode, the Grid. View cannot page over the data returned by Sql. Data. Source. The following example demonstrates the Grid. View paging UI against a Sql. Data. Source in Data. Set mode. Grid. View also supports a special mode for paging and sorting that takes advantage of client- side. To enable this. feature, set the Enable. Sorting. And. Paging. Callbacks property to true. Notice that when. This. feature is not supported when the Grid. View contains templated fields. Showing a Select. Command. Field is also not supported when this feature is enabled. Just like sorting and paging, the Grid. View control can also automatically render UI for modifying data through Update and Delete operations, provided the associated data source is configured to support these capabilities. The Sql. Data. Source control supports Update operations when its Update. Command property is set and Delete operations when its Delete. Command property is set to a valid update or delete command or stored procedure. The Update. Command or Delete. Command should contain parameter placeholders for each value that will be passed by the Grid. View control. To enable the UI in the Grid. View for Updates or Deletes, you can either set the Auto. Generate. Edit. Button and Auto. Generate. Delete. Button properties to true, or you can add a Command. Field to the Grid. View control and enable its Show. Edit. Button and Show. Delete. Button properties. The Grid. View supports editing or deleting one row at a time. For editing, the user places the row in edit mode by clicking the Edit button, and then confirms the Update by clicking the Update button while the row is in edit mode. The user can also click the Cancel button to abort the edit operation and return to read- only mode. The following example shows the a Grid. View and Sql. Data. Source configured for updating data rows. An important property that plays a special role in Update and Delete operations is the Data. Key. Names property. This property is typically set to the names of fields from the data source that. Multiple keys are comma- separated when specifying this property declaratively, although it is common to only have one primary. The values of fields specified by the Data. Key. Names property are round- tripped in viewstate for the sake of retaining original values to pass to an Update or Delete operation, even if that. Grid. View control. When the Grid. View invokes the data source Update or Delete operation, it passes the values of these fields to the data source. Keys dictionary, separate from the Values dictionary that contains new values entered by the user while the row is in edit mode (for update operations). The contents of the Values dictionary are obtained from the input controls rendered for the row in edit mode. To exclude a value from this dictionary, set the Read. Only property. to true on the corresponding Bound. Field in the Column collection. If you are using the Grid. View designer in Visual Studio, the Read. Only property is set to true for primary key fields by default. For more information and examples that demonstrate the use of the Grid. View control, refer to the. Performing Data Access section.
