XRTable.BeginInit() Method
Starts the XRTable‘s initialization. Initialization occurs at runtime.
Namespace: DevExpress.XtraReports.UI
Assembly: DevExpress.XtraReports.v20.2.dll
NuGet Packages: DevExpress.Reporting.Core, DevExpress.WindowsDesktop.Reporting.Core
Declaration
Remarks
To create XRTable at runtime and manually add XRTableRow and XRTableCell objects to it, it is always required to enclose this code inside the BeginInit and XRTable.EndInit method calls.
Because the final size of a table does not consider the size of its rows and cells , you need to manually set the table size and width (or, call the XRTable.AdjustSize method) before calling the XRTable.EndInit method.
Note
The height of a table should be explicitly specified only if the cell content is not expected to stretch the cells (e.g., this may happen when their XRTableCell.CanGrow property is enabled).
Example
The code sample below illustrates how to create an XRTable at runtime.
Tip
Online Example: Runtime table creation best practices (iterative approach)
using DevExpress.XtraReports.UI;
// ...
// Create a report.
XtraReport report = new XtraReport();
// Create a detail band and add it to the report.
DetailBand detailBand = new DetailBand();
report.Bands.Add(detailBand);
// Create a table and add it to the detail band.
XRTable table = new XRTable();
detailBand.Controls.Add(table);
// Add rows and colums to the table.
int numRows = 10;
int numCols = 20;
table.BeginInit();
for (int i = 0; i < numRows; i++) {
XRTableRow row = new XRTableRow();
table.Rows.Add(row);
for (int j = 0; j < numCols; j++) {
XRTableCell cell = new XRTableCell();
table.Rows[i].Cells.Add(cell);
}
}
// Set table size.
table.HeightF = 50;
table.WidthF = 500;
table.EndInit();
The following code sample creates an XRTable at runtime and binds the table to data:
using DevExpress.XtraReports.UI;
using DevExpress.DataAccess.Sql;
using DevExpress.DataAccess.ConnectionParameters;
// ...
private static SqlDataSource CreateSQLDataSource() {
// Create a data source with the required connection parameters.
Access97ConnectionParameters connectionParameters = new Access97ConnectionParameters("Data/nwind.mdb", "", "");
SqlDataSource dataSource = new SqlDataSource(connectionParameters);
// Create a SELECT query.
SelectQuery query = SelectQueryFluentBuilder
.AddTable("Products")
.SelectColumn("ProductName")
.SelectColumn("UnitPrice")
.Build("selectQuery");
// Add the query to the collection and return the data source.
dataSource.Queries.Add(query);
dataSource.Fill();
return dataSource;
}
// ...
// Create a new data source.
SqlDataSource sqlDataSource = CreateSQLDataSource();
// Create a new report and assign the data source to it.
XtraReport report = new XtraReport();
report.DataSource = sqlDataSource;
report.DataMember = "Products";
// Create a detail band and add it to the report.
DetailBand detailBand = new DetailBand();
report.Bands.Add(detailBand);
// Create a table and add it to the detail band.
XRTable table = new XRTable();
detailBand.Controls.Add(table);
// Create a row and add the product name and product price cells to the row.
table.BeginInit();
XRTableRow row = new XRTableRow();
table.Rows.Add(row);
XRTableCell productName = new XRTableCell();
XRTableCell productPrice = new XRTableCell();
row.Cells.Add(productName);
row.Cells.Add(productPrice);
// Bind the table cells to the data fields.
productName.ExpressionBindings.Add(new ExpressionBinding("BeforePrint", "Text", "[ProductName]"));
productPrice.ExpressionBindings.Add(new ExpressionBinding("BeforePrint", "Text", "[UnitPrice]"));
table.EndInit();
