Introduction
Note |
---|
This is Part 3 of the three-part tutorial series Financial Report scenario. It is recommended that you complete Part 1 - Using Modifiers and Ordinal Syntax and Part 2 - Using Styles and Formatting before starting this section. This tutorial also assumes a basic understanding of how to open and manipulate Excel files with ExcelApplication. |
Getting Started
This section covers using ExcelApplication to join two Worksheets into one Workbook. These two worksheets were created in Part 1 and Part 2 of this tutorial.
Info | ||
---|---|---|
| ||
In the downloadable ExcelWriter_Basic_Tutorials.zip, there are completed template files located in CompleteFinancialReport/templates. |
Adding an ExcelWriter Reference in Visual Studio
Info | ||
---|---|---|
| ||
In the sample code, the reference to SoftArtisans.OfficeWriter.ExcelWriter.dll has already been added to the CompleteFinancialReport project. |
Create a .NET project and add a reference to the ExcelWriter library.
- Open Visual Studio and create a .NET project.
- The sample code uses a web application.
- Add a reference to SoftArtisans.OfficeWriter.ExcelWriter.dll
- SoftArtisans.OfficeWriter.ExcelWriter.dll is located under Program Files > SoftArtisans > OfficeWriter > dotnet > bin
Writing the Code
Merging template together with CopySheet
1. Include the SoftArtisans.OfficeWriter.ExcelWriter namespace in the code behind
Code Block |
---|
using SoftArtisans.OfficeWriter.ExcelWriter; |
2. Globally declare the ExcelTemplate, ExcelApplication, and Workbook objects.
Code Block |
---|
ExcelApplication XLA; ExcelTemplate XLT; Workbook MERGEDWB; |
3. Define a method that will open the two template files and merge them together with CopySheet. In this case, the method is called MergeTemplates()
.
Code Block |
---|
protected void MergeTemplates() { } |
4. In MergeTemplates()
, instantiate the ExcelApplication object.
Code Block |
---|
XLA = new ExcelApplication(); |
5. Open the workbook that the worksheets will be copied into. For this example, the second template will be copied into the first template workbook.
Code Block |
---|
MERGEDWB = XLA.Open(Page.MapPath("//templates//Part1_Financial_Template.xlsx")); |
6. Open the second workbook that will be merged into the first.
Code Block |
---|
Workbook wbOther = XLA.Open(Page.MapPath("//templates//Part2_Financial_Template.xlsx")); |
7. Copy the worksheet from the second template into the first workbook. Worksheet.Name can be used to pass along the original name of the worksheet ("Percent by Quarter"). The worksheet should be copied to the end of the current worksheet collection (index 1).
Code Block |
---|
MERGEDWB.Worksheets.CopySheet(wbOther[0], 1, wbOther[0].Name); |
Binding Data to the Merged Template
1. Create a method to handle binding and processing the data import for the combined template. For this example, the method is called BindDataToMergedTemplate()
.
Code Block |
---|
protected void BindDataToMergedTemplate() { } |
2. Instantiate ExcelTemplate and open the template file with ExcelTemplate.Open(ExcelApplication, Workbook) to open directly from the pre-existing ExcelApplication instance.
Code Block |
---|
XLT = new ExcelTemplate(); XLT.Open(XLA, MERGEDWB); |
3. Use the code from Part 1 and Part 2 to bind data to the template. Note that both templates used the same data set, so the calls to bind the data only need to be made once.
Info |
---|
If there are duplicate data markers in a workbook, ExcelWriter will import the matching data to all the data markers, across all the worksheets in the workbook. |
Code Block |
---|
//Create data binding properties for ExcelTemplate DataBindingProperties bindingProps = XLT.CreateDataBindingProperties(); //Create the array of header values. This example only binds a single item string[] headerValues = { "2011" }; //Create the array of header names. string[] headerNames = { "FiscalYear" }; //Get the datatables to be bound into the template. //This example uses CSV data, but the data can come from //anywhere DataTable dtAssets = GetCSVData("//data//Assets.csv"); DataTable dtLosses = GetCSVData("//data//Losses.csv"); DataTable dtOther = GetCSVData("//data//Other.csv"); //Bind the header row data XLT.BindRowData(headerValues, headerNames, "Header", bindingProps); //Bind the datatables XLT.BindData(dtAssets, "Assets", bindingProps); XLT.BindData(dtLosses, "Losses", bindingProps); XLT.BindData(dtOther, "Other", bindingProps); //Process to import the data to the file XLT.Process(); XLT.Save(Page.Response, "Part3_Output.xlsx", false); |

It will be ignored by the second template, since there are no markers to bind to.*/ //Create the array of header values. This example only binds a single item string[] headerValues = { "2011" }; //Create the array of header names. string[] headerNames = { "FiscalYear" }; //Bind the header row data XLT.BindRowData(headerValues, headerNames, "Header", bindingProps); //end //Process to import the data to the file XLT.Process(); XLT.Save(Page.Response, "Part3_Output.xlsx", false); } |
