How to design the Details Section of a group at the run time

[Utku Ozan]

I am trying to create a report which will basically show data in groups. But the thing is that for each group the data to display might vary, both in columns and rows. This is why I can not design a Details Section at the Design-Time. While starting to process each group I am converting the necessary data while the groupHeader is being bound with:

private void groupHeaderSection4_ItemDataBound(object sender, EventArgs e)
{
    Telerik.Reporting.Processing.GroupSection dtl = (Telerik.Reporting.Processing.GroupSection)sender;
    sectionsData = ConvertToDataTable(dtl);
}

which is OK. But after getting this re-constructed DataTable I want to design the Details Section of the Group according to the DataTable returned; which basically means to create columns and rows manually.

To create a custom grid on the fly I am trying to create TextBoxes and manually design them. This is where it gets stuck. I am doing this while binding data to the Details Section as:

	private void detail_ItemDataBinding(object sender, EventArgs e)
	{
	Telerik.Reporting.Processing.DetailSection dtl = (Telerik.Reporting.Processing.DetailSection)sender;
	dtl.Items.Clear();
	ProcessingBindColumnNames(dtl);
	}
	protected void ProcessingBindColumnNames(Telerik.Reporting.Processing.DetailSection dtl)
	{
	double columnWidth = (double)(Convert.ToDouble(dtl.Width) - Convert.ToDouble(tbDurumWidth)) / (sectionsData.Columns.Count - 1);
	tbColumnWidth = new Telerik.Reporting.Drawing.Unit(columnWidth, UnitType.Cm);
	for (int c = 0; c < sectionsData.Columns.Count - 1; c++)
	{
	Telerik.Reporting.Processing.TextBox tb = new Telerik.Reporting.Processing.TextBox();
	}
	}

But at the line 14 I am getting "The Type 'Telerik.Reporting.Processing.TextBox' has no constructors defined".

How can I create a TextBox while binding the Group Details Section and why this item has no constructor but Intellisense brings me one when I type new?

Regards.

Try changing

Telerik.Reporting.Processing.TextBox tb = new Telerik.Reporting.Processing.TextBox();



to

Telerik.Reporting.TextBox tb = new Telerik.Reporting.TextBox();

Of course I can create the TextBox from

    Telerik.Reporting.TextBox tb = new Telerik.Reporting.TextBox();

but this time after creating and formatting necessary controls I can not add them to the detailsSection which created from the type of

    Telerik.Reporting.Processing.DetailSection

As far as I can understand Telerik.Reporting.Processing objects can only interact with objects from the same class.

Hello Utku Ozan,

The very idea of creating processing items is not a good one and Telerik.Reporting.Processing.TextBox does not have a constructor as it's not meant to be used for creating items. As Juzzer suggested, you should work with the definition items.
