[Solved] Multiple images in a RadgridView cell

[Jorge]

Hi, I have a requirement to have multiple icons in a cell, I have created a custom GridViewDataColumn and a GridDataCellElement

My current implementation has 2 issues, the icons don't appear until you enter or leave a row (in which case only those rows icons get displayed), or when you click on the column (in which case all the visible rows display their icons.

The second issue is that, since I can scroll horizontally, when scrolling right, the cell locations that end up under the location of my icons cells, when you scroll left again, they appear empty, and you need to reload the Datasource or scroll multiple times vertically for them to appear again.

What I'm doing right now is overriding the ArrangeOverride, to locate the icons on the cell with Children[i].Arrange, and creating the icons overriding SetContent and OnCellFormatting and creating LightVisualElements there, calling Children.Clear() at the beginning of the methods.

I'll try to post an example later but has anyone had an issue like this before?

Hi, Jorge,

Thank you for contacting us!

I understand that you have created a custom GridViewDataColumn and a GridDataCellElement, which is great, but it would be difficult to determine what is causing these two issues on your side without having the exact custom implementation that you have. It is possible to provide me with a sample project that contains your custom GridViewDataColumn and GridDataCellElement classes. Thus, I could be able to assist you more effectively regarding your custom setup.

I’m sharing the following resources related to custom cell examples, which may be helpful for this topic. You can see the implementation for custom elements there and see if there is something missing on your side:

In case you still need further assistance, providing a sample project would be much appreciated to assist you further.
