[Solved] Drag & Drop Between Grids with Different Data Models / Error Sorting & Filtering on Unique Fields

Good Day,

I have been implementing drag&drop functionality between two Telerik Blazor grids using different data models. Using the documentation article as a reference below, I am able to get 2 models (derived from the same interface) to drag between 2 grids.

How to Drag and Drop Different Models between Multiple Grids - Telerik UI for Blazor

However, grid functions such as sorting and filtering start throwing errors, when unique fields are introduced per model. To re-produce, start with the demo code in the artcile and try and sort "Unique Field 1". This throws an exception: "Unhandled exception rendering component: Invalid property or field - 'UniqueField1' for type: IParentSampleData". See screenshot attached.

This makes sense, but it's very limiting. My question is, if this can "worked around" in any way.

I have tried to intercept the "StateChanged" event. But as I still need to call gridObj.SetStateAsync(args.GridState), I cannot circumvent the issue. As per the error, I assume that these Grid methods use the interface definition and not the actual model instance to determine available properties for filtering & sorting, etc.

Is there somethig I am missing? Would anyone have any experience with this scenario and could point me in the direction of a "work around" if one exists?

Many thanks,
Peter

Series click on aggregated chart

I'm using a chart with BaseUnit="ChartCategoryAxisBaseUnit.Fit"

Aggregate="ChartSeriesAggregate.Sum", Type="ChartCategoryAxisType.Date"

When clicking on a series it returns a single date (day) and not the date range that were used for the aggregation.

I need the range in order to show the full result list in a grid.

How can it be done?

Grid hierarchy cell icons

Hello!
Since you changed the classes for displaying table icons, tell us how to change these terrible + and - to other icons?
Previously, the code was working:
.k-hierarchy-cell .k-icon.k-i-plus::before {
content: "\e005";
cursor: pointer;
font-size: 1.3em
}

.k-hierarchy-cell .k-icon.k-i-minus::before {
content: "\e006";
cursor: pointer;
font-size: 1.3em
color: rgb(var(--primary-a));
background-color: rgb(var(--primary-d));
border-radius: 4px
}

Display 1 values with logarithmic scaled chart

(I am having the same issue as this WPF forum question, but cannot seem to translate the fix for Blazor.)
For the log chart, I am always wanting a bar to display as long as the value itself is not zero.

Would anyone be able to help me?
