How to Assign a Value to Infragistics WebTextEdit Using JavaScript

Other Questions JavaScript
1

I’m utilizing the Infragistics toolkit for .Net 2.0 with Visual Studio 2005 and C#. Here’s a snippet of my JavaScript code (text and other variables have been defined prior):

alert(list[choice].value);
textField.setValue(list[choice].value);
alert(textField.getValue());

In this code, ‘textField’ represents an Infragistics webTextEdit, while ‘list’ refers to a basic listbox. Although the alerts function as expected, updating the ‘textField’ does not reflect the new value in the form display. For example, when the listBox currently shows ‘hello’, both alerts show ‘hello’ after setting the value. However, the form’s display does not get updated. Can anyone help identify what I might be missing or any common pitfalls with Infragistics in this context? I admit that there might not be enough detail provided to troubleshoot effectively.

Make sure you call textField.update() after setting the value:

textField.setValue(list[choice].value);
textField.update();

This should update the display with the new value. Infragistics controls often require an update call to reflect changes in the UI.

In addition to ensuring you call textField.update() after setting the value, as CreativeArtist88 suggested, it's crucial to check that the control's client-side object model is being utilized correctly. Infragistics controls sometimes have specific initialization requirements.

Here's a more detailed approach that might help:

// Assuming 'list[choice].value' and 'textField' are properly initialized
textField.setValue(list[choice].value);

// Call update to ensure the value shows on the UI
textField.update();

// Make sure that the control is initialized (if applicable)
if (!textField.isInitialized) {
    textField.initialize();
}

Also, verify that the textField element is properly rendered in the DOM before you attempt to manipulate it. Having a conditional check for the control's readiness is often a good practice.

Furthermore, double-check for any JavaScript errors in the browser console that may prevent the display update, and ensure all necessary resources (like scripts and styles for Infragistics) are correctly loaded.

These steps should help you diagnose and resolve display issues with Infragistics web controls in your application.

Hi Hazel, updating Infragistics controls can sometimes be tricky due to their client-side dependencies. As previous responders pointed out, using textField.update() is crucial for ensuring the UI reflects changes. However, here’s a streamlined approach to tackle this issue:

// Set value from listBox
textField.setValue(list[choice].value);

// Immediately update the UI
textField.update();

// Ensure control is initialized and ready
if (!textField.isInitialized) {
    textField.initialize();
    textField.update(); // Update again post initialization
}

1. Make certain all necessary Infragistics scripts are loaded before executing your code.

2. Confirm the control is fully initialized using conditional checks as shown.

3. Inspect the browser console for JavaScript errors that might disrupt execution.

Following these steps enhances reliability in updating the textField and ensures the form display matches your expectations. Let me know if you encounter further issues!
