Error when saving a double in DataGrid

[zawarq]

I have a DataGrid with the following column definition (amongst others):

PatientLabTest.TestValue has type double. The data loads from server. When I create a new record, or edit an existing record whereby I change the TestValue, I get the following error in the browser console:

Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100]
Unhandled exception rendering component: Specified cast is not valid.
System.InvalidCastException: Specified cast is not valid.

at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)
at Microsoft.AspNetCore.Components.RenderTree.Renderer.GetErrorHandledTask(Task taskToHandle, ComponentState owningComponentState)

The above error occurs before I hit my OnRowInsert/Update handlers.

If I edit an existing record, and saving it without changing the value of TestValue, it works fine.

Note this this datagrid was working fine when I had Blazorise version 1.2, but when I upgraded to the latest 1.4.0 this error started appearing.

Any help will be greatly appreciated :)

Hello, It does seem to be a bug we've mistakenly introduced in 1.4. The DataGridColumn is not figuring out the correct value type for numeric types.
You should be able to use a DataGridNumericColumn instead while we work on the fix.
I'll go ahead and open an issue.

Thanks David! I'll look into DataGridNumericColumn now Regards Zawar

Sure. In the meantime I forgot to link the related issue.
