Create a Window with a Workbook and a Button

1. Open the SpreadsheetGear 2023 category in the Visual Studio Toolbox.
2. Click and drag WorkbookView onto MainWindow.
3. In Visual Studio 2013 and later you will need to give the new WorkbookView instance the name 'workbookView1' by selecting the WorkbookView, pressing F4 for Properties, and changing the Name property from <No Name> to 'workbookView1'.

6. Adjust the size of MainWindow and the controls as desired.

Add Code to Calculate a Value and Display it in a Cell

1. Double click the Button to display the Button's Click event handler.
2. Copy the following code to the Button's Click event handler.

   Simple WPF Sample

   Copy Code

   // Interrupt background calculation if necessary and acquire a lock on the workbook set. workbookView1.GetLock(); try { // Get a reference to the active cell. SpreadsheetGear.IRange activeCell = workbookView1.ActiveCell; // Set a formula activeCell.Formula = "=24901.55 / PI()"; // Place the result of the formula in cell B2. SpreadsheetGear.IRange b2 = workbookView1.ActiveWorksheet.Cells["B2"]; b2.Value = "The diameter of the earth is " + activeCell.Text + " miles."; // Set the font of B2 to italic. b2.Font.Italic = true; } finally { // Release the lock on the workbook set. workbookView1.ReleaseLock(); }

Build and Run the Application

1. On the Build menu, click Build Solution.  The solution builds with no errors.
2. On the Debug menu, click Start Without Debugging.  The application runs in a window and when you click the Button, cell B2 will display "The diameter of the earth is 7926.409546 miles."
