The child content element 'ChildContent' of component 'X' uses the same parameter name ('context') ...
When you nest DevExpress Blazor components that contain RenderFragment<TValue> properties, a Razor error can occur. For example, the following code nests a DxButton component within a DxFormLayoutItem component.
<DxFormLayoutItem>
<Template>
<DxButton>OK</DxButton>
</Template>
</DxFormLayoutItem>
Both components include properties that specify render fragments: DxFormLayoutItem‘s Template and DxButton‘s ChildContent. This means that Blazor adds Context implicit parameters to each component:
<DxFormLayoutItem>
<Template Context="context">
<DxButton Context="context">OK</DxButton>
</Template>
</DxFormLayoutItem>
The Context parameters have the same default value. This causes the following error:
Error RZ9999 The child content element ‘ChildContent’ of component ‘DxButton’ uses the same parameter name (‘context’) as enclosing child content element ‘Template’ of component ‘DxFormLayoutItem’. Specify the parameter name like: ‘<ChildContent Context=”another_name”>’ to resolve the ambiguity.
To fix the issue, specify the Context parameter explicitly in one of the components:
<DxFormLayoutItem>
<Template>
<DxButton Context="buttonCtx">OK</DxButton>
</Template>
</DxFormLayoutItem>
