Dynamic columns with IDictionary<string, object>

[Pedro]

I want to bind a table to a list of objects, each object has a IDictionary.

public ObjectInstance
{ 
   public IDictionary<string, object> Dictionary { get; set; }

The source is a IEnumerable of ObjectInstance's, I've tried this with no success:

void table1_ItemDataBinding(object sender, EventArgs e)
    {
        //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 textboxGroup;
        Telerik.Reporting.HtmlTextBox textBoxTable;


        //we do not clear the Rows collection, since we have a details row group and need to create columns only
        this.table1.ColumnGroups.Clear();
        this.table1.Body.Columns.Clear();
        this.table1.Body.Rows.Clear();
        int i = 0;
        this.table1.ColumnHeadersPrintOnEveryPage = true;
        var attributes = _objectInstances.First().ObjectType.Attributes;
        foreach (var attribute in attributes)
        {
            if (string.IsNullOrWhiteSpace(attribute.ColumnName)) continue;


            var tableGroupColumn = new Telerik.Reporting.TableGroup();
            this.table1.ColumnGroups.Add(tableGroupColumn);
            this.table1.Body.Columns.Add(new Telerik.Reporting.TableBodyColumn(Unit.Inch(1)));


            textboxGroup = new Telerik.Reporting.HtmlTextBox();
            textboxGroup.Style.BorderColor.Default = Color.Black;
            textboxGroup.Style.BorderStyle.Default = BorderType.Solid;
            textboxGroup.Value = attribute.ColumnName;
            textboxGroup.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
            tableGroupColumn.ReportItem = textboxGroup;


            textBoxTable = new Telerik.Reporting.HtmlTextBox();
            textBoxTable.Style.BorderColor.Default = Color.Black;
            textBoxTable.Style.BorderStyle.Default = BorderType.Solid;
            textBoxTable.Value = "=Dictionary[\"" + attribute.ColumnName + "\"]"; //_objectInstances.First()[attribute.ColumnName].ToString();
            textBoxTable.Size = new SizeU(Unit.Inch(1.1), Unit.Inch(0.3));
            this.table1.Body.SetCellContent(0, i++, textBoxTable);
            this.table1.Items.AddRange(new ReportItemBase[] {textBoxTable, textboxGroup});
        }


    }

Which is the correct way to bind to a dictionary ?

Hello Pedro,

The ObjectDataSource support any types that derive from ICollection such as IDictionary to access to Keys and Values properties. However based on the provided information we are not sure about your goal, thus we will appreciate if you elaborate further on your scenario and open a support thread to send us a sample runnable project to examine locally.

Best wishes,
Peter
