Possible UI Parameter Rendering Issue in Azure Data Factory Dataset Configuration

Question

Dear Microsoft Azure Support Team,

I hope you are doing well.

I would like to report a possible issue I have observed while working with Azure Data Factory. While creating parameterized datasets for dynamic data movement, I noticed inconsistent behavior in the parameter expression UI.

Issue Description: When multiple parameters are created in a dataset and expressions are defined, the UI sometimes displays only one parameter input box instead of showing all defined parameters.

Steps to Reproduce:

Create or edit a dataset in Azure Data Factory.

Define multiple parameters in the dataset.

Use the dataset inside a pipeline and assign expressions to parameters.

Observe that sometimes only one parameter input box appears instead of all parameters.

If the dataset is deselected and then reselected, all parameter input boxes appear correctly.

Expected Behavior: All defined parameters should consistently appear in the UI without needing to deselect and reselect the dataset.

Actual Behavior: Only one parameter input box is shown intermittently, which may lead to confusion during pipeline configuration.

Impact: This behavior may cause configuration mistakes and increases development time while working with parameterized datasets.

Please let me know if additional logs, screenshots, or reproduction details are required. I would be happy to assist further in investigating this issue.

Thank you for your support and for continuously improving Azure services.

Hi Salman Khan
Thanks for the clear explanation - that helps.

What you’re describing sounds like a UI refresh issue in Azure Data Factory rather than a problem with your dataset configuration. Since all parameters appear correctly after you deselect and reselect the dataset, it suggests the parameters are saved properly but the UI doesn’t refresh sometimes.

A few things you can try:

• Refresh the browser page and try again
• Try another browser or use Incognito/InPrivate mode
• Clear browser cache if this happens often

These UI glitches can sometimes be session-related.

If the behavior continues, it would be good to raise a support ticket and share screenshots and the steps you listed. That helps the product team check if there is a UI bug.

From what you described, it should not affect how the pipeline runs - it’s mainly a display issue in the UI.

Thanks for reporting it - feedback like this helps improve the service.

Answer 2

It seems you are experiencing an issue with the Azure Data Factory UI regarding the rendering of parameter input boxes in datasets. This behavior, where only one parameter input box is displayed instead of all defined parameters, can indeed lead to confusion and potential configuration mistakes.

While the context provided does not explicitly mention this specific UI issue, it is important to ensure that you are using the latest version of Azure Data Factory, as UI inconsistencies can sometimes be resolved with updates. Additionally, if this issue persists, it may be beneficial to report it through official support channels for Azure, as you have outlined in your message.

If you have already tried deselecting and reselecting the dataset to make all parameters visible, it could be a temporary glitch in the UI. Keeping your Azure Data Factory environment updated and providing feedback to Microsoft could help in addressing this inconsistency in future updates.
