+## Environment
+
+<table>
+    <tbody>
+        <tr>
+            <td> Product </td>
+            <td> Reporting </td>
+        </tr>
+    </tbody>
+</table>
+
+## Description
+
+I need to display overlapping date ranges inside a [Crosstab/Table/List]({%slug telerikreporting/designing-reports/report-structure/table-crosstab-list/overview%}) report item. Each row represents a unit, and each monthly cell should visually depict three date ranges with distinct background colors. 
+
+The ranges overlap, and their rendering should follow a layered approach, with the outermost range appearing behind the inner ones. I need guidance on calculating pixel positions dynamically and rendering layered backgrounds within each cell.
+
+## Solution
+
+To achieve layered background rendering for overlapping date ranges:
+
+1. Use a [Crosstab]({%slug crosstab_item_get_started%}) item to represent the data in a tabular format.
+1. Place a [Panel]({%slug telerikreporting/designing-reports/report-structure/panel%}) inside the crosstab cells where you need to display the date ranges. The panel will occupy the entire cell and act as a *container* for other elements, such as **TextBox** items. This approach allows you to configure the textboxes as needed, since a single textbox alone would otherwise fill the entire cell.
+1. Add multiple [TextBox]({%slug telerikreporting/designing-reports/report-structure/textbox%}) items inside the panel to represent the date ranges. Each TextBox should correspond to a single date range color.
+1. Bind the [Location](/api/telerik.reporting.reportitem#Telerik_Reporting_ReportItem_Location) and [Width](/api/telerik.reporting.reportitem#Telerik_Reporting_ReportItem_Width) of each TextBox dynamically using [Bindings]({%slug telerikreporting/designing-reports/connecting-to-data/expressions/using-expressions/bindings%}). This ensures the rectangles are rendered proportionally based on the date range extracted from the data.
+
+### Example
+
+Below is an example dataset and binding configuration:
+
+**Sample Data:**
+
+```csv
+text,date,month,sizex,position
+1,01/01/2025,1,0.5in,1.5in
+1,01/01/2025,2,0.3in,0in
+```
+
+>note Ensure that the data includes the X and Y positions, and the sizes of the range bars. These values determine the length of the colored textbox that is being used to represent the range bar.
