【Stimulsoft Reports.WinForms教程】從代碼打印數(shù)據(jù)網(wǎng)格

【下載Stimulsoft Reports.Ultimate最新版本】

此示例顯示如何從代碼中打印數(shù)據(jù)網(wǎng)格，數(shù)據(jù)網(wǎng)格是以表格形式呈現(xiàn)的數(shù)據(jù)，在Form1_Load事件中創(chuàng)建并填充數(shù)據(jù)集合：

private void Form1_Load(object sender, System.EventArgs e)
{
    DataTable table = new DataTable("Demo");
 
    table.Columns.Add();
    table.Columns.Add();
 
    DataRow row1 = table.NewRow();
    DataRow row2 = table.NewRow();
    DataRow row3 = table.NewRow();
 
    row1.ItemArray = new string[2]{"1", "One"};
    row2.ItemArray = new string[2]{"2", "Two"};
    row3.ItemArray = new string[2]{"3", "Three"};
 
    table.Rows.Add(row1);
    table.Rows.Add(row2);
    table.Rows.Add(row3);
    dataView1.Table = table;
}

更詳細(xì)地看一下PrintDataGrid方法，首先在dictionary中創(chuàng)建一個(gè)新的報(bào)表和數(shù)據(jù)源：

private void PrintDataGrid(DataGrid sender)
{
    DataView dataView = (DataView)sender.DataSource;
    StiReport report = new StiReport();
    report.ScriptLanguage = StiReportLanguageType.CSharp;
 
    //Add data to datastore
    report.RegData("view", dataView);
 
    //Fill dictionary
    report.Dictionary.Synchronize();
...  

向報(bào)表添加Data Band和Header Band：

...
    StiPage page = report.Pages.Items[0];
 
    //Create HeaderBand
    StiHeaderBand headerBand = new StiHeaderBand();
    headerBand.Height = 0.5f;
    headerBand.Name = "HeaderBand";
    page.Components.Add(headerBand);
 
    //Create DataBand
    StiDataBand dataBand = new StiDataBand();
    dataBand.DataSourceName = "view" + dataView.Table.TableName;
    dataBand.Height = 0.5f;
    dataBand.Name = "DataBand";
    page.Components.Add(dataBand);
...

將Text Boxes參照上數(shù)據(jù)源字段Data Band，和Text Boxes與數(shù)據(jù)的Header Band：

...
    //Create texts
    Double pos = 0;
    Double columnWidth = StiAlignValue.AlignToMinGrid(page.Width / dataView.Table.Columns.Count, 0.1, true);
    int nameIndex = 1;
    foreach (DataColumn column in dataView.Table.Columns)
    {
        //Create text on header
        StiText headerText = new StiText(new RectangleD(pos, 0, columnWidth, 0.5f));
        headerText.Text.Value = column.Caption;
        headerText.HorAlignment = StiTextHorAlignment.Center;
        headerText.Name = "HeaderText" + nameIndex.ToString();
        headerText.Brush = new StiSolidBrush(Color.LightGreen);
        headerText.Border.Side = StiBorderSides.All;
        headerBand.Components.Add(headerText);
 
        //Create text on Data Band
        StiText dataText = new StiText(new RectangleD(pos, 0, columnWidth, 0.5f));
        dataText.Text.Value = "{view" + dataView.Table.TableName + "." +
            Stimulsoft.Report.CodeDom.StiCodeDomSerializator.ReplaceSymbols(column.ColumnName) + "}";
        dataText.Name = "DataText" + nameIndex.ToString();
        dataText.Border.Side = StiBorderSides.All;
 
        //Add highlight
        StiCondition condition = new StiCondition();
        condition.BackColor = Color.CornflowerBlue;
        condition.TextColor = Color.Black;
        condition.Expression = "(Line & 1) == 1";
        condition.Item = StiFilterItem.Expression;
        dataText.Conditions.Add(condition);
 
        dataBand.Components.Add(dataText);
 
        pos += columnWidth;
 
        nameIndex ++;
    }
...

然后，添加一個(gè)Footer Band與Text Box的報(bào)表顯示出Total值：

...
    //Create FooterBand
    StiFooterBand footerBand = new StiFooterBand();
    footerBand.Height = 0.5f;
    footerBand.Name = "FooterBand";
    page.Components.Add(footerBand);
 
    //Create text on footer
    StiText footerText = new StiText(new RectangleD(0, 0, page.Width, 0.5f));
    footerText.Text.Value = "Count - {Count()}";
    footerText.HorAlignment = StiTextHorAlignment.Right;
    footerText.Name = "FooterText";
    footerText.Brush = new StiSolidBrush(Color.LightGreen);
    footerBand.Components.Add(footerText);
...

最后，渲染報(bào)表并在查看器中顯示它：

...
    //Render without progress bar
    report.Render(false);
    report.Show();
}
