Perform Mail Merge in Presentations
Introduction
In the world of .NET development, creating dynamic and personalized presentations is a common requirement. One powerful tool that simplifies this process is Aspose.Slides for .NET. In this tutorial, we’ll delve into the fascinating realm of performing mail merge in presentations using Aspose.Slides for .NET.
Prerequisites
Before we embark on this journey, make sure you have the following prerequisites in place:
- Aspose.Slides for .NET Library: Ensure you have the Aspose.Slides for .NET library installed. You can download it from here.
- Document Template: Prepare a presentation template (e.g., PresentationTemplate.pptx) that will serve as the base for mail merge.
- Data Source: You need a data source for mail merge. In our example, we’ll use XML data (TestData.xml), but Aspose.Slides supports various data sources like RDBMS. Now, let’s dive into the steps of performing mail merge in presentations using Aspose.Slides for .NET.
Import Namespaces
Firstly, ensure you import the necessary namespaces to leverage the functionalities provided by Aspose.Slides:
using System;
using System.Collections.Generic;
using System.Data;
using System.Drawing;
using System.IO;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Aspose.Slides;
using Aspose.Slides.Charts;
using Aspose.Slides.Examples.CSharp;
using Aspose.Slides.Export;
using DataTable = System.Data.DataTable;
Step 1: Set Up Your Document Directory
string dataDir = "Your Document Directory";
string presTemplatePath = Path.Combine(dataDir, "PresentationTemplate.pptx");
string resultPath = Path.Combine(RunExamples.OutPath, "MailMergeResult");
// Check if result path exists
if (!Directory.Exists(resultPath))
Directory.CreateDirectory(resultPath);
Step 2: Create a DataSet Using XML Data
using (DataSet dataSet = new DataSet())
{
dataSet.ReadXml(dataPath);
DataTableCollection dataTables = dataSet.Tables;
DataTable usersTable = dataTables["TestTable"];
DataTable staffListTable = dataTables["StaffList"];
DataTable planFactTable = dataTables["Plan_Fact"];
Step 3: Loop Through Records and Create Individual Presentations
foreach (DataRow userRow in usersTable.Rows)
{
// create result (individual) presentation name
string presPath = Path.Combine(resultPath, "PresFor_" + userRow["Name"] + ".pptx");
// Load presentation template
using (Presentation pres = new Presentation(presTemplatePath))
{
// Fill text boxes with data from the main table
((AutoShape)pres.Slides[0].Shapes[0]).TextFrame.Text = "Chief of the department - " + userRow["Name"];
((AutoShape)pres.Slides[0].Shapes[4]).TextFrame.Text = userRow["Department"].ToString();
// Get image from the database
byte[] bytes = Convert.FromBase64String(userRow["Img"].ToString());
// Insert image into the picture frame of the presentation
IPPImage image = pres.Images.AddImage(bytes);
IPictureFrame pf = pres.Slides[0].Shapes[1] as PictureFrame;
pf.PictureFormat.Picture.Image.ReplaceImage(image);
// Get and prepare the text frame for filling it with data
IAutoShape list = pres.Slides[0].Shapes[2] as IAutoShape;
ITextFrame textFrame = list.TextFrame;
textFrame.Paragraphs.Clear();
Paragraph para = new Paragraph();
para.Text = "Department Staff:";
textFrame.Paragraphs.Add(para);
// Fill staff data
FillStaffList(textFrame, userRow, staffListTable);
// Fill plan fact data
FillPlanFact(pres, userRow, planFactTable);
pres.Save(presPath, SaveFormat.Pptx);
}
}
Step 4: Fill Text Frame with Data as a List
static void FillStaffList(ITextFrame textFrame, DataRow userRow, DataTable staffListTable)
{
foreach (DataRow listRow in staffListTable.Rows)
{
if (listRow["UserId"].ToString() == userRow["Id"].ToString())
{
Paragraph para = new Paragraph();
para.ParagraphFormat.Bullet.Type = BulletType.Symbol;
para.ParagraphFormat.Bullet.Char = Convert.ToChar(8226);
para.Text = listRow["Name"].ToString();
para.ParagraphFormat.Bullet.Color.ColorType = ColorType.RGB;
para.ParagraphFormat.Bullet.Color.Color = Color.Black;
para.ParagraphFormat.Bullet.IsBulletHardColor = NullableBool.True;
para.ParagraphFormat.Bullet.Height = 100;
textFrame.Paragraphs.Add(para);
}
}
}
Step 5: Fill Data Chart from the Secondary PlanFact Table
static void FillPlanFact(Presentation pres, DataRow row, DataTable planFactTable)
{
IChart chart = pres.Slides[0].Shapes[3] as Chart;
IChartTitle chartTitle = chart.ChartTitle;
chartTitle.TextFrameForOverriding.Text = row["Name"] + " : Plan / Fact";
DataRow[] selRows = planFactTable.Select("UserId = " + row["Id"]);
string range = chart.ChartData.GetRange();
IChartDataWorkbook cellsFactory = chart.ChartData.ChartDataWorkbook;
int worksheetIndex = 0;
// Add data points for line series
chart.ChartData.Series[0].DataPoints.AddDataPointForLineSeries
(cellsFactory.GetCell(worksheetIndex, 1, 1, double.Parse(selRows[0]["PlanData"].ToString())));
chart.ChartData.Series[1].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 1, 2, double.Parse(selRows[0]["FactData"].ToString())));
chart.ChartData.Series[0].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 2, 1, double.Parse(selRows[1]["PlanData"].ToString())));
chart.ChartData.Series[1].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 2, 2, double.Parse(selRows[1]["FactData"].ToString())));
chart.ChartData.Series[0].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 3, 1, double.Parse(selRows[2]["PlanData"].ToString())));
chart.ChartData.Series[1].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 3, 2, double.Parse(selRows[2]["FactData"].ToString())));
chart.ChartData.Series[0].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 3, 1, double.Parse(selRows[3]["PlanData"].ToString())));
chart.ChartData.Series[1].DataPoints.AddDataPointForLineSeries(
cellsFactory.GetCell(worksheetIndex, 3, 2, double.Parse(selRows[3]["FactData"].ToString())));
chart.ChartData.SetRange(range);
}
