Reviewer's Guide

Enable automatic filtering when the user types into the string filter by adding a dedicated change event handler and updating the input component’s binding to fire on each value change.

Hey there - I've reviewed your changes - here's some feedback:

• Consider adding a configurable debounce or delay in OnValueChanged so you don’t invoke the filter logic on every keystroke, which can improve performance on large data sets.
• Expose an optional parameter (e.g. AutoFilterEnabled) to let consumers opt into auto‐filtering on input change rather than making it always on by default.

<code_context>
         await base.SetFilterConditionsAsync(filter);

+    private async Task OnValueChanged(string? val)
+    {

+        await OnFilterAsync();

 }
</code_context>

<issue_to_address>
**issue (bug_risk):** OnValueChanged does not handle potential exceptions from OnFilterAsync.

Add error handling to OnValueChanged to catch exceptions from OnFilterAsync and prevent UI disruptions.
