How can I embed a React form within a Syncfusion Dialog modal?

Below is one approach you can try. In our experience, one common culprit is the use of the target prop on the DialogComponent. When you set target to a specific DOM element (by id or ref), the dialog’s content might be rendered in a way that interferes with event propagation for the inner form (and its buttons and API calls). Here are some steps you can follow:

---

1. Remove the Target

If you don’t require the dialog to attach to a particular element, omit the target prop. This lets the dialog render in its default container and often resolves issues with inner components not receiving events. For example:

JAVASCRIPTCopied
import { DialogComponent } from "@syncfusion/ej2-react-popups";
import Login from "./Login";

const LoginFormModal = () => {
  return (
    <div className="control-pane">
      <DialogComponent
        id="defaultDialog"
        showCloseIcon={true}
        visible={true}
        width={"700px"}
        isModal={true}
      >
        <Login />
      </DialogComponent>
    </div>
  );
};

export default LoginFormModal;

2. Ensure the Inner Form Is Self-Contained

Double-check that your Login component (your form) handles its events correctly. Make sure the form’s submission handler calls e.preventDefault() (if needed) and that button types are set appropriately (e.g., type="submit" on the submit button). For example:

JAVASCRIPTCopied
export default function Login() {
  function handleSubmit(e) {
    e.preventDefault();
    // perform API call or state update as needed
    console.log("Form submitted");
  }

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label>
          Username:
          <input name="username" />
        </label>
      </div>
      <div>
        <label>
          Password:
          <input type="password" name="password" />
        </label>
      </div>
      <button type="submit">Login</button>
    </form>
  );
}

---

3. Use Refs When Targeting a Specific Element

If you must render the dialog within a specific container, prefer using React refs over relying solely on string IDs. This ensures that the target element is in sync with React’s render cycle. For example:

JAVASCRIPTCopied
import { useRef } from 'react';
import { DialogComponent } from "@syncfusion/ej2-react-popups";
import Login from "./Login";

const LoginFormModal = () => {
  const containerRef = useRef(null);

  return (
    <div className="control-pane" ref={containerRef}>
      <DialogComponent
        id="defaultDialog"
        showCloseIcon={true}
        visible={true}
        width={"700px"}
        target={containerRef.current} // using the ref here
        isModal={true}
      >
        <Login />
      </DialogComponent>
    </div>
  );
};

export default LoginFormModal;

Note: When using refs for the target, ensure the ref is not null—this might involve a conditional render or effect to confirm the element is available.

By following the above adjustments—especially removing or carefully managing the target prop—you should see the modal behave as expected, with buttons and API calls inside the Login form functioning normally.
