This guide will explain how to import a single row of values into a PowerPoint presentation using data markers. This assumes a basic understanding of data markers. |

PowerPointTemplate has a single method for binding data to the data markers that are located in the template: PowerPointTemplate.BindData
. Depending on the data source type and the number of rows in the data source, PowerPointWriter will either import a single row of data or import multiple rows.
There are several ways to import a single row of data into a presentation:
DataBindingProperties
objectMethods:
[PowerPointTemplate.BindData(Object[],String[],String,DataBindingProperties)]
[PowerPointTemplate.BindData(Object[][],String[],String,DataBindingProperties)]
[PowerPointTemplate.BindData(Object
,
,String[],String,DataBindingProperties)]
Arrays don't have built-in means to store column names. The user must specify the column names in a string array that is passed to PowerPointTemplate.BindData
at run time.
If a multidimensional array (Object[,]
) or a jagged array (Object[][]
) contains multiple rows, PowerPointWriter will import all the rows using built-in repeating behavior. To import a single row of data using a multidimensional or jagged array, the array can only contain a single row of data. For more information about using arrays to import multiple rows of data, please see Importing Multiple Rows of Data.
One dimensional array:
PowerPointTemplate pptt = new PowerPointTemplate(); pptt.Open(@"C:\DataBinding\ArrayBindingTemplate.pptx"); string[] values = {"Hello World", "subtitle"}; string[] colNames = {"header", "subtitle"}; DataBindingProperties DataProps = pptt.CreateDataBindingProperties(); pptt.BindData(values, colNames, "DataSource1", DataProps); pptt.Process(); pptt.Save(Page.Response, "ArrayBinding.pptx", false); |
Dim pptt As New PowerPointTemplate() pptt.Open("C:\DataBinding\ArrayBindingTemplate.pptx") Dim values = New String() {"Hello World", "subtitle"} Dim colNames = New String() {"header", "subtitle"} Dim DataProps As DataBindingProperites = pptt.CreateDataBindingProperties(); pptt.BindData(values, colNames, "DataSource1", DataProps); pptt.Process() pptt.Save(Page.Response, _ "ArrayBinding.pptx", _ False) |
MaxRowsToImport is a data binding property that can be used to control how many rows of data to import from the data set. When using data sources other than a single dimensional array, a single row of data can be imported by setting MaxRowsToImport to 1.
DataBindingProperties DataProps = pptt.DataBindingProperties(); DataProps.MaxRowsToImport = 1; |
