Hi,

I use this telerik for quite sometime now. My question is about the radgrid. We use radgrid quite intensively.

Im trying to delete data using dataadapter and call refresh function of the grid.

dataset.tables(0).row(0).delete
dataadapter.update(dataset)
grid.refresh

The grid didnt refresh and the data is still there. I checked the database, it deleted.

I thought my coding is working then i tried using microsoft grid and I can the desired result. Please help. Is this bug?

Another case: when i try to update and grid is updated.

What happen?

Greetings,

In chart view documentation, Lasso Zoom segment, there is a highlight box drawn when Lasso Zoom area is specified via dragging mouse. But when I tested on my side, there is nothing visual drawn and shown when specifying the Lasso Zoom area, however the Lasso Zoom feature works just fine. Is there Anyway to draw a rectangular box corresponding to the area specified for Lasso Zoom like the picture I attached ? Thanks in advance.

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.
