XRTable.BeginInit() Method

Starts the XRTable‘s initialization. Initialization occurs at runtime.

Namespace: DevExpress.XtraReports.UI

Assembly: DevExpress.XtraReports.v23.2.dll

NuGet Package: DevExpress.Reporting.Core

Declaration

C#

public void BeginInit()

VB.NET

Public Sub BeginInit

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.

C#

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.
XRTable table = new XRTable();

// 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();

// Add the table to the detail band and adjust the band height.
detailBand.Controls.Add(table);
detailBand.HeightF = table.HeightF;

VB.NET

Imports DevExpress.XtraReports.UI
' ...
            ' Create a report.
            Dim report As New XtraReport()

            ' Create a detail band and add it to the report.
            Dim detailBand As New DetailBand()
            report.Bands.Add(detailBand)

            ' Create a table.
            Dim table As New XRTable()

            ' Add rows and colums to the table.
            Dim numRows As Integer = 10
            Dim numCols As Integer = 20

            table.BeginInit()

            For i As Integer = 0 To numRows - 1
                Dim row As New XRTableRow()
                table.Rows.Add(row)

                For j As Integer = 0 To numCols - 1
                    Dim cell As New XRTableCell()
                    table.Rows(i).Cells.Add(cell)
                Next j
            Next i

            ' Set table size.
            table.HeightF = 50
            table.WidthF = 500

            table.EndInit()

            ' Add the table to the detail band and adjust the band height.
            detailBand.Controls.Add(table)
            detailBand.HeightF = table.HeightF
