如何创建动态RDLC数据表

Question

I need to pass to RDLC (SQL Server Reporting Services) report a data table with only one known column and all other columns are created at run time. That is I have column A that is know at design time, but before loading the report i will read values from the database and set these values as columns, may be i have one column and may be much more.

I tried this :

dsStatementOfAccount.DtEndDayDataTable dtMat = new dsStatementOfAccount.DtEndDayDataTable(); dtMat.Columns.Add("c1"); dtMat.Columns.Add("c2"); DataRow row1 = dtMat.NewRow (); row1["Name"] = "Value for column name in row 1"; row1["c1"] = "a"; row1["c2"] = "a121"[1] dtMat.Rows.Add(row1); DataRow row2 = dtMat.NewRow(); row2["Name"] = "Value for column name in row 2"; row2["c1"] = "bbb"; row2["c2"] = "bbb"; dtMat.Rows.Add(row2);

 dsStatementOfAccount.DtEndDayDataTable dtMat = new dsStatementOfAccount.DtEndDayDataTable();  dtMat.Columns.Add("c1"); dtMat.Columns.Add("c2"); DataRow row1 = dtMat.NewRow (); row1["Name"] = "Value for column name in row 1"; row1["c1"] = "a"; row1["c2"] = "a121"[1] dtMat.Rows.Add(row1); DataRow row2 = dtMat.NewRow(); row2["Name"] = "Value for column name in row 2"; row2["c1"] = "bbb"; row2["c2"] = "bbb"; dtMat.Rows.Add(row2); 

But the report was loaded as the attached image .. How it can be done ?

Thanks

Answer 1

You should be able to do this by creating a column group that is grouped by your "NAME" column.

After adding your table to your report, define all static columns. Then, right-click on the cell where you want the dynamic columns to start at and select "Add Group > Parent Group (Under the column group section)" and choose to Group By "NAME". This should produce the desired effect.
