How to: Create a Master-Detail Report Without Coding

To get started, create a new spreadsheet application with the help of the DevExpress Template Gallery .

• Start a new project in Visual Studio, select DevExpress Template Gallery, and launch Project Wizard. Select required options for a Winforms Ribbon Form Spreadsheet application and click Create.

  

  The application will be created automatically.

• When a new application is ready, click the SpreadsheetControl smart tag in the Visual Studio designer and select Create Mail Merge Bars to add a Mail Merge tab.
• Select Create Field List Panel to add the Field List Panel panel to the right of the SpreadsheetControl.
• Select Create Parameters Panel to add the Parameters Panel to the bottom right of the SpreadsheetControl.
• Run the application.

• Create a new workbook. Modify a document by entering captions, changing cell fonts and backgrounds and formatting cell ranges as shown in the following picture.

  

• Activate the Mail Merge Design View to display the template structure. To do this, click the Mail Merge Design View button on the Mail Merge tab, in the Design group.
• Click Add Data Source to invoke Data Source Wizard.
• Select Database as the data source type. Click Next.

  

• Select an option to create a new data connection. Click Next.
• Select the MS Access 97 data provider and locate the database file nwind.mdb in the Data subfolder of the DevExpress demos. Click Next.
• Select an option that does not save credentials. Click Next.
• Click Run Query Builder to invoke the Query Designer window that enables you to select data from the data source.

• Add the Suppliers table and include all columns into the query.

  

  Click OK to close Query Designer.
• Click Next to save the query.
• Click OK to select the newly created data source.
• Click Manage Relations -> Manage Queries to invoke Query Designer and create a new query for the Products table.
• Click Manage Relations -> Manage Queries to invoke Query Designer and create a new query for the Order Details table.

• Click Manage Relations to invoke the Master-Detail Relations Editor.
• Add relations to the Suppliers and Products tables. The editor suggests appropriate relations automatically.

  

• Select the "B3:I13" cell range and click the Detail button on the Mail Merge tab, in the Template Ranges group. This cell range will be repeated for each record of the data source.
• Click Select Data Member to invoke a dialog to select Suppliers as the data member in the worksheet data source.
• Specify a header to display above all detail range instances in the resulting worksheet. Select the "B3:I3" range. Click the Header button on the Mail Merge tab.
• Add a nested level to the detail range to display the detail-level data from the SuppliersProducts child table. Select the "B9:I13" cell range, click the Master-Detail button, and then click Detail Level in the invoked submenu. The DetailLevel0 range will be created.
• Select Master-Detail->Data Member to specify SuppliersProducts nested data member for the Detail Level 0.
• Select the "D13:I13" cell range for the next level sub-detail area (Detail Level 1) and click Master-Detail->Detail Level to mark it up.
• Select Master-Detail->Data Member to specify ProductsOrder Details nested data member for the DetailLevel1.

The resulting template is shown below:

• Select a cell and double-click the field in the Field List panel. Make sure that the fields are selected from the nested data member that has been previously specified for the area to which a field is inserted. The resulting template will look as illustrated in the following image.

  

• Select the Mail Merge mode. Click Multiple Sheets to place a report for each supplier into an individual worksheet.

• Click the Mail Merge Preview button on the Mail Merge tab, in the Design group. A new window with a resulting document opened in a new SpreadsheetControl instance will be invoked.

  

  You can save the resulting workbook to a file and edit it later.

• You can also save a data-bound template to a file in .xls or .xlsx format. All data bindings are saved and will be restored when the spreadsheet control loads a template again.
