Adding columns to a table at processing time

[Frédéric]

Hi,

I have a table report item in the detail section.

For each detail row, the table is bound to a DataTable in the NeedDataSource event handler of the table.

The DataTable columns vary from one detail row to an other. Say, for the first detail row, the DataTable could have 2 columns and in  the second detail row, the DataTable could have 5 different columns.

I would like to add columns to the table at processing time (like inside the NeedDataSource event handler) in order to display the DataTable bound to the table.

Thanks a lot.

Frederic

Hello Frédéric,

As we are not very sure what you're trying to achieve, please provide us with a screenshot/drawing of how your table should look like for a couple of detail records. Any additional information you can provide and consider helpful would be appreciated.

Hello Steve,

To simplify things, I would like to know if it is possible to create a Table ReportItem programmatically, like other report items as documented here http://www.telerik.com/help/reporting/programmatic-creating-controls.html.

I am looking at the api and I can not figure how to programmatically add columns to a Table.

Thanks a lot.

Hello Frédéric,

I am afraid that this is a bit more complicated than simple matter of rows and columns. We encourage you to open the sample reports we ship with our installation, locate the ProductCatalog report and check the table item used there. It does look like a table right :) If you however check the InitializeComponent method you would notice that these are defined as ColumnGroups and RowGroups i.e.:
...
this.table1.ColumnGroups.Add(tableGroup7);
..
this.table1.RowGroups.Add(tableGroup8);
...

The body is defined with  this.table1.Body.SetCellContent() method where you specify the rowIndex, columnIndex and the report item in that cell.

You can find more information on those in the "Working with Table/CrossTab/List items" help section:

• Understanding the CrossTab/Table/List report items
• Understanding table cells, rows and columns
