Table textbox.value blank

[Pierre-Alain]

Hello,

I'm trying to create a dynamic table columns. It's almost working, but the actual data is not showing up:

public partial class ProductsReport : Telerik.Reporting.Report
    {
        public ProductsReport()
        {
            InitializeComponent();

            detail.ItemDataBound += detail_ItemDataBinding;
        }

        private void detail_ItemDataBinding(object sender, EventArgs e)
        {
            var section = sender as Telerik.Reporting.Processing.DetailSection;
            var processingTable = section.ChildElements.Find("periodsTable", true)[0] as Telerik.Reporting.Processing.Table;
            var dataObject = section.DataObject;
            var productPricingInfos = dataObject.RawData as ProductPricingInfos;
            processingTable.DataSource = productPricingInfos.ProductPricePeriods;

            //create two HtmlTextBox items (one for header and one for data) which would be added to the items collection of the table
            Telerik.Reporting.HtmlTextBox textboxHeader;
            Telerik.Reporting.HtmlTextBox textBoxData;

            //we do not clear the Rows collection, since we have a details row group and need to create columns only
            this.periodsTable.ColumnGroups.Clear();
            this.periodsTable.Body.Columns.Clear();
            this.periodsTable.Body.Rows.Clear();
            int i = 0;
            this.periodsTable.ColumnHeadersPrintOnEveryPage = true;

            //common fields
            var tableGroupColumnCommon = new Telerik.Reporting.TableGroup();
            periodsTable.ColumnGroups.Add(tableGroupColumnCommon);
            periodsTable.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Inch(1)));

            textboxHeader = new Telerik.Reporting.HtmlTextBox();
            textboxHeader.Style.BorderColor.Default = Color.Black;
            textboxHeader.Style.BorderStyle.Default = BorderType.Solid;
            textboxHeader.Value = "Du";
            textboxHeader.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
            tableGroupColumnCommon.ReportItem = textboxHeader;

            textBoxData = new Telerik.Reporting.HtmlTextBox();
            textBoxData.Style.BorderColor.Default = Color.Black;
            textBoxData.Style.BorderStyle.Default = BorderType.Solid;
            textBoxData.Value = "=Fields.StartDate";
            textBoxData.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
            this.periodsTable.Body.SetCellContent(0, i++, textBoxData);
            this.periodsTable.Items.AddRange(new ReportItemBase[] { textBoxData, textboxHeader });


        }
    }

You can see at the bottom textBoxData.Value = "Fields.StartDate". I took this from an example submitted by you guys.

I'm probably missing a bind or something...I really don't know.

Well...I've got it working. I've just binded the periodsTable Datasource to =Fields.ProductPricePeriods and ive got it working.

Now, the only thing thats bugging me is why in preview mode, html preview mode or online in a ReportViewer, the first element of the subreport is always blank but when I export to PDF, its there! See the attached screenshot and PDF.

Hi Kogik,

Most likely you have set the DataSource to the definition table item, when it should be set to the processing object instead when in the context of event. More information on definition vs. processing is available in our documentation: Understanding Report Items.

Kind regards,
