I need to display radio buttons in my report. Based on the result from database, appropriate radio button should be selected. Until now I have been using just. Generate a Clickthrough Report using Visual Studio Report. Viewer. Based on the number of questions Ive seen about the Visual Studio Report. Viewer control, it appears that many administrators dont know that this control can perform sophisticated operations on its own. You might have seen examples of SQL Server Reporting Services SSRS clickthrough reports, but did you know that this same functionality is available when generating a local report with the Report. Viewer A local report doesnt require an SSRS server because the application provides the tools to distribute the report. So, even without benefit of SSRS, you can give the user the ability to execute parameter driven reports of all kindseven drillthrough reports. Report. Viewer also lets developers manage input parameters and integrate reports with other UI elements on the form or ASP page. While it might seem challenging to implement a report with the Report. Viewer control because youre responsible for much of the leg work, in the end youll find this an essential tool when creating forms over data applications. This control gives developers virtually infinite flexibility in how the Report Definition Language RDL is presented. For a comprehensive explanation of how to create and manage reports with Report. Viewer, see Report. Viewer Samples for Microsoft Visual Studio 2. Although you can use either Visual Studio VS 2. VS 2. 00. 5 to set up a clickthrough report without using SSRS, after SQL Server 2. VS 2. 00. 8 will include SSRS hooks, which will make VS 2. Note that in VS 2. Report. Viewer has been renamed Microsoft Report. Viewer. Creating the Project and Datasource. To create a project and datasource, you first need to build an example application. Start by creating a new Windows Forms project in VS. I created a strongly typed datasource that points to the SQL Server Adventure. Works example database. I chose not to select any table, view, or stored procedure sources for the data set because I want to illustrate how to use the Table. Adapter Designer to create a new Table. Adapter from scratch. The following steps take you through the code generation process for the first Table. Adapter. 1. In the new Windows Forms project, click the Data menu and select Add New Data Source. For the Data Source Type, select Database. Confirm the Data Connection or point to the Adventure. Works sample database. Adventure. Works is available as either an optional installation choice or a download. When prompted for selected Database Objects, click Finish without selecting anythingno Tables, Views, Stored Procedures, or Functions. Confirm this lack of selection. Doing so creates an empty Table. Adapter. XSD Data. Set. 6. Right click the Adventure. Works. Data. Set. Solution Explorer, and select Open. Click Toolbox to open the Data. Set toolbox window in the VS UI. Now youre ready to auto generate the first of two Table. Adapter classes to be used as report row sources. Click and drag a Table. Adapter to the XSD designer pane. Doing so relaunches the Table Adapter Configuration Wizard but exposes a different set of options. Then click Next. 9. Select Use SQL statements, and click Next. Youll see a dialog box in which you can enter a SQL query to return a rowset to populate the base report in this case. Type a SQL statement that returns columns required by the report and calls for a single input parameter, as shown in Web Listing 1. Note that the SQL statement could be a stored procedure, but entering it yourself makes it easier to understand the process. Click Advanced Options and clear Generate Insert, Update, and Delete statements to disable the generation of the code for these statements. Youre creating a report, not a data management front end. Click OK and then Next. In the Choose Methods to Generate dialog box, clear the check box to disable code generation for the Return a Data. Table and Generate. DBDirect. Methods. You need only a Fill at this point. Click Next, and Finish. Now that VS has completed the code generation for the first Table. Adapter, repeat the process to create a second Table. Adapter to return rows for the drillthrough query. The code generation process for the second Table. Adapter is similar to the process for the first Table Adapter, with a few changes. Repeat steps 8 1. Web Listing 2 SQL statement in step 1. This parameter query uses the Product. ID passed from the report processor as the input parameter. After youve created the new Table. Adapter, right click the diagram and rename it Stock. By. Product. Now you have the two related row sources that you can use to generate a clickthrough report. Creating the RDLC Reports. This example uses Report Definition Language Client Side RDLC reports one to show products by style and another to display details on a selected product. The first report displays pertinent information from the Products table based on the Product Table. Adapter. The second report displays information from selected rows based on the Product. Inventory Table. Adapter. Although I wont go into great detail about how to build a report, here is a brief summary of how to do so Add a new Report item to the Project, and then add a Table Report item. Drag appropriate fields from the Data Sources Data. Set to the Table item. Note that these operations are recorded in the RDLC and that the Data. Set name is an integral part of this process. Note that when youre working with report Data. Sets, you must use the Data. Set name to help the report processor know where to apply the data youre returning. To complete the report, set some colors and a few formatting properties. For more information about building reports, see Take Control of Your Reports with Report. Viewer. Figure 1 shows how the report appears in the designer when completed. Note that if you were to use existing report definition files, youd need to reconnect them to the correct Data Source elements. The second report as shown in Figure 1 includes data from columns from the Stock. By. Product Table. Adapter rowset. Linking to the Clickthrough Report. Now youre ready to link the two reports together. The idea is to display the Stock on Hand report shown in Figure 1 when the user clicks a Product Number item in the Stock report shown in Figure 2 by passing the currently selected Product number to the Product Inventory Fill. By. Product. Number query as a parameter. Linking the two reports is accomplished by editing the RDLC report definition files using the Report Designer built into VS. The following steps take you through the process of linking two reports together. In the Stock report, right click the Product Number cell to open the Textbox Properties pane. Note that because the Textbox report cell is a property, it can be set with an expression. This means you can trigger any RDLC report you want toas long as the report processor can find it at runtime. Click the Navigation tab, and set Jump to report to the name of the drillthrough RDLC file, as shown in Figure 3. Now, set up the parameter to be passed to the linked report. Click the Parameters button, which is shown in Figure 3. In the Parameters dialog box, shown in Figure 4, enter Product. IDWanted as the Parameter Name and choose the expression for Product. ID from the drop down list. Click OK twice to return to the RDLC designer. Setting Up the Report. Viewer Control. To have VS generate most of the UI code, you can leverage the Table. Adapter and VSs ability to set up the UI elements to capture the input parameter, Style Wanted, for the initial query. Style. Wanted should be sufficient because you wont need any UI elements to browse through the rowset or make changes. The following steps take you through setting up the Report. Viewer Control. 1. Open the Form. 1 design mode window. Drag the Product data set from the Data Sources window to the form design surface. Doing so adds the Product. Table. Adapter to the forms generated code. It also adds a label and textbox to capture the parameter, and a Fill button to launch the Fill method defined for the Table. Adapter. In addition, it supplies a Data. Grid. View control, and Table Adapter. Manager, Binding. Source, and Binding. Navigator classes that you dont need. Delete these unneeded classes theyre used to provide update and scrolling mechanisms that you dont need. All you want is the tool strip to manage the parameter and expose the Fill button. The result should look like Figure 5. Now drag the Report. Viewer control to the form. Load RDLC Report Using Report Viewer Programmatically.
