I want to do a bind datatable to reportviewer with the code below. I don't see the results appear in the reportviewer, what the lack of script below?
// create dataset
DataSet ds = new DataSet("myDataset");
// create datatable
DataTable dt = new DataTable("myDatatable");
// add columns
dt.Columns.Add("column1", typeof(string));
dt.Columns.Add("column2", typeof(string));
dt.Columns.Add("column3", typeof(string));
// insert data rows
dt.Rows.Add("row1-col1", "row1-col2", "row1-col3");
dt.Rows.Add("row2-col1", "row2-col2", "row2-col3");
// add datatable to dataset
ds.Tables.Add(dt);
// bind datatable to report viewer
this.reportViewer.Reset();
this.reportViewer.ProcessingMode = ProcessingMode.Local;
this.reportViewer.LocalReport.ReportEmbeddedResource = "Test.Report1.rdlc";
this.reportViewer.LocalReport.DataSources.Clear();
this.reportViewer.LocalReport.DataSources.Add(new ReportDataSource(dt.TableName, dt));
this.reportViewer.RefreshReport();

I found the answer how to bind datatable to reportviewer, I will shared here may be useful for others.
- 添加到表单clsTables 类、Report1.rdlc 文件、reportViewer1.
- 然后点击reportViewer1的右上角,将选择报告设置为Test.Report1.rdlc.
- 关于 Report1.rdlc
- 点击新建,
- 添加数据集名称:dsBody数据源:测试可用数据集:clsTables
- 点击确定
- 右键单击 Report1.rdlc 选择 插入表,将 dsBody 元素(Column0、Colum1、Column2)拖到 Report1.rdlc 表.
- Add to form clsTables class, Report1.rdlc file, reportViewer1.
- Then Click on the upper right corner of the reportViewer1, set choose report to Test.Report1.rdlc.
- On Report1.rdlc
- Click New,
- Add dataset name: dsBody Data source: Test Available dataset: clsTables
- Click Ok
- Right click on Report1.rdlc select Insert Table, drag dsBody element(Column0, Colum1, Column2) to Report1.rdlc table.
Namespace Test{
public class clsTables {
// constructor
public clsTables(string col0, string col1, string col2) {
this.Column0= col0;
this.Column1= col1;
this.Column2= col2;
}
// properties
public string Column0{ get; set; }
public string Column1{ get; set; }
public string Column2{ get; set; }
}
}
namespace Test{
public class clsMain{
public void BindToRepprtViewer() {
// create dataset
DataSet ds = new DataSet("myDataset");
// create datatable
DataTable dt = new DataTable("myDatatable");
// add columns
dt.Columns.Add("column1", typeof(string));
dt.Columns.Add("column2", typeof(string));
dt.Columns.Add("column3", typeof(string));
// insert data rows
dt.Rows.Add("row1-col1", "row1-col2", "row1-col3");
dt.Rows.Add("row2-col1", "row2-col2", "row2-col3");
// add datatable to dataset
ds.Tables.Add(dt);
// save rows to rowList
List<clsTables> rowList = new List<clsTables>();
rowList .Clear();
foreach (DataRow row in dt.Rows) {
rList.Add(new clsTables(Convert.ToInt32(row.ItemArray[0]), row.ItemArray[1].ToString(), row.ItemArray[2].ToString()));
}
// binding rowList to bs
BindingSource bs = new BindingSource();
bs.DataSource = rowList;
// binding bs to rds
ReportDataSource rds = new ReportDataSource();
rds.Name = "dsBody";
rds.Value = bs;
// binding rds to report viewer
reportViewer1.Reset();
reportViewer1.LocalReport.ReportEmbeddedResource = "Test.Report1.rdlc";
reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.DataSources.Add(rds);
reportViewer1.RefreshReport();
}
}
}
