The model properties should display vertically and the model values should display horizontally. + +## Solution + +The Telerik Grid for Blazor does not support transposing. A transposed Grid requires a different architecture, implementation and UI. Thus, a transposed Grid must be a separate component, such as the [Telerik PropertyGrid for Blazor](https://feedback.telerik.com/blazor/1468343-propertygrid-property-grid-vertical-oriented-grid-with-cell-labels-in-column-1). Vote for the feature request and follow it to receive future status updates. + +## Suggested Workarounds + +Here are a few possible ways to display transposed data: + +* Use the [Telerik Form component for Blazor]({%slug form-overview%}) instead of a Grid. The Form does not provide Grid features, but it can be databound to a model object and supports editing. +* Render static HTML markup, which uses the Grid CSS classes. This will produce Grid-like UI, but without any additional built-in features. +* Combine the previous two options to achieve a Form that looks like a Grid. Use the Grid's HTML markup in a [Form `FormItemsTemplate`]({%slug form-formitems-formitemstemplate%}). Optionally, remove the [built-in Form submit button by using an empty `` tag]({%slug form-formitems-buttons%}). + +Alternatively, shape the data structure, so that it's suitable to display in a regular non-transposed Grid. + +The following example demonstrates all options. + +>caption Implement a PropertyGrid or a transposed Grid + +````CSHTML +
