Question

To add a dropdown list to a Windows application using C# and RDLC, you can follow these steps: Open your Windows application project in Visual Studio. Create a new RDLC report or open an existing one. Drag and drop a "Report Parameter" from the Toolbox onto the RDLC report design surface. Right-click on the newly added parameter and select "Properties". In the properties window, set the "DataType" to "Text" and provide a suitable name for the parameter. Save the RDLC report. Now, let's move on to adding the dropdown list to the Windows application form: Open the form where you want to add the dropdown list. Drag and drop a "ComboBox" control from the Toolbox onto the form. In the properties window, set the "DataSource" property to the dataset that contains the data for the dropdown list. Set the "DisplayMember" property to the column name that should be displayed in the dropdown list. Set the "ValueMember" property to the column name that should be used as the value when an item is selected. Save the form. To pass the selected value from the dropdown list to the RDLC report, you need to modify the code that generates the report: Open the code file associated with the form. Locate the code that generates the report. Set the value of the report parameter to the selected value from the dropdown list. Here's an example of how you can set the report parameter value: ReportParameter parameter = new ReportParameter("ParameterName", comboBox1.SelectedValue.ToString()); this.reportViewer1.LocalReport.SetParameters(parameter); Make sure to replace "ParameterName" with the actual name of the report parameter and "comboBox1" with the name of your ComboBox control.
