Issue: feature #327

Now you can select nodownlaod model.

Show this image.

You can open code panel.

Export:(Only one option)

Minor comments, but otherwise works great:

• When navigating between model groups, make sure the non-downloaded models list unselectes model when other group selects a model. To repro, open the model picker, select a non-downloaded model, navigate to other group (like Windows AI APIs) and select a model there, and then navigate back to ONNX models - the non-downloaded model remains selected but it shouldn't.

  

• The message in the sample container when a non-downloaded model should be more descriptive with button to download the model and a button to view the code. Right now, it's not clear how to download the model or that I can still view the code. Consider having the code view open automatically when a non-downloaded model is selected.

• Exporting the project with non downloaded model should maybe include a note that the sample will not work because the model is not downloaded.

I think we can improve how this looks in the code - Need Download feels awkard. Consider something like path-to-model-files-once-downloaded to make it clear it's a path value that goes there.

Which of the following do you mean to change?

• cachedModel = new(selectedModelDetails.Id, "path-to-model-files-once-downloaded",
• cachedModel = new(selectedModelDetails.Id, "C:\Users\xxx.cache\aigallery\microsoft--Phi-4-mini-instruct-onnx\main\cpu_and_mobile\cpu-int4-rtn-block-32-acc-level-4",
• cachedModel = new(selectedModelDetails.Id, "", (this code can use "App.ModelCache.IsModelCached(selectedModel.Url)" to check model status)

• fixed the first problem.
• add some tips in Sample page when select nodownload model. add consider having the code view open automatically when a non-downloaded model is selected.

- add tips in after click export button window.

topic:

If want add download button near this button, I think need some design.

Because model have different status, like warrning and download.

@wang563681252 what would the additional download button do? Wouldn't it be confusing to have multiple places to download models?

Also, you could consider grey-ing out the modelpicker button when no model is downloaded / available?

Hi @niels9001,

@nmetulev say: "The message in the sample container when a non-downloaded model should be more descriptive with button to download the model and a button to view the code. Right now, it's not clear how to download the model or that I can still view the code. Consider having the code view open automatically when a non-downloaded model is selected."

I think the meaning of this passage is for me to add a download button next to the selected model, but I don't think it's a good idea. I am discussing it with Nikola.
