Unlocking the World of Business Intelligence with SQLBI

, or custom data-binding logic.ItemInserting:

ItemUpdating:

ModeChanged:
ItemDataBound

, or programmatically through ADO.NET.SqlConnection
for SQL Server).SqlCommand

).SqlDataAdapter

, DataTable
).Connecting to a Database:
SqlConnection
class is commonly used for SQL Server databases.Executing Queries and Commands:
SqlCommand
class to execute SQL queries like SELECT
, INSERT
, UPDATE
, and DELETE
.INSERT
or UPDATE
.SELECT
.Filling Data into a DataSet:
SqlDataAdapter
class is used to fill data from the database into a DataSet
. The Fill
method is used to populate a DataTable
with data.DataSet
allows manipulation of data offline, and changes can later be saved back to the database.Updating the Database:
DataSet
can be saved back to the database using the SqlDataAdapter
's Update
method. This automatically generates the necessary INSERT
, UPDATE
, or DELETE
commands.Custom Sorting:
ORDER BY
clauses or sort the data programmatically in a DataTable
before binding it to the GridView
.Handling Editing and Updating in GridView:
UPDATE
SQL command.SqlCommand
is used to update data in the database and then rebind the GridView
to reflect changes.Deleting Rows in GridView:
GridView
can be achieved by capturing the row’s identifier (e.g., primary key) and using it in a DELETE
SQL command executed through ADO.NET.Handling Paging:
Creating and Executing Stored Procedures:
SqlCommand
object by setting its CommandType
property to CommandType.StoredProcedure
.Passing Parameters to Stored Procedures:
SqlParameter
objects. This allows you to safely pass user inputs to the stored procedure, preventing SQL injection attacks.Custom Paging: The GridView can handle paging of large datasets using the PageSize property. For more control, you can handle custom paging logic by handling the PageIndexChanging event. This allows you to retrieve data in chunks from the database and control page navigation yourself.
Custom Sorting: By default, GridView allows sorting by clicking on column headers. For more customized sorting, you can use the SortCommand event and create your own sorting logic.
Custom Editing: GridView allows in-place editing, but you can customize the editing interface by using the EditItemTemplate. This allows you to use custom controls (e.g., dropdown lists, text boxes) for editing data.
Custom Insertion and Deletion: The GridView provides mechanisms to insert and delete records. You can create custom forms for insertion or deletion and handle these operations programmatically by using the RowInserting, RowDeleting, and RowEditing events.
TemplateField: The TemplateField provides the most flexibility in customizing the display of data. You can use custom controls and HTML elements within the TemplateField to display data.
BoundField: A BoundField is used to display values from a data source in the grid. You can format data using the DataFormatString property or apply security measures using the HtmlEncode property.
