Hi

I have found examples showing how to use a RadProgressBarElement in a grid column. I added one to my project and it is working, well almost.

If all my values are positive (ie between 0 and 100), the column shows correctly.

But my values are between -100 and 100. I have set the Minimum property to -100. I see some values with a red zone (which is ok). But shouldn't the green zone only start at 0 (right in the middle)?

We are having an odd issue with the RadGrid component on build 2021.2.511.40

We have isolated the issue down to the base component in a sample project and the issue still occurs. I have attached the Sample project.

Steps to reproduce:

Filter the checkbox column to only show unchecked rows
Enter "alfred" as the description filter
Click the checkbox column on the bottom two rows (Sku RT34)
Remove description filter
This will result in the two unrelated records showing as checked. Scrolling or changing sorting will refresh the cell.

RadCallout is like a tooltip with an arrow that can be used to display additional information, warnings, hints, or to highlight relevant data. The appearance of the control can be fully customized to satisfy the needs of your scenarios.

Get familiar with it: https://docs.telerik.com/devtools/winforms/controls/callout/overview
