Mastering Blazorise DataGrid: How to Bind a TextEdit in EditTemplate

Getting started with Blazor and Blazorise can be daunting, especially when you’re trying to figure out how to bind variables in a DataGrid's EditTemplate. If you've been scratching your head over this, you’re not alone. Many new developers face similar challenges, and today we will unravel the complexities of binding a TextEdit to your DataGrid.

The Problem

You may have a scenario where you want to edit a field in a Blazorise DataGrid. For instance, you want to edit the description of a ProductVo in a DataGrid column, as shown in the example below:

While the above code allows for displaying the value when editing, it fails to save any modifications made. The root cause is due to incorrect binding of context.CellValue. If you are struggling with saving edits made to TextEdit, you're in the right place for a solution!

The Solution

To successfully bind the TextEdit so that changes are saved, you need to handle the TextChanged event. This event is responsible for capturing changes made to the text field and updating the respective context.

Step-by-Step Instructions

Update the TextEdit component. Change your existing <TextEdit> binding to the format below:

What this change does is ensure that whenever the text changes in the input, it updates context.CellValue with the new value.

Validate the Input. Ensure that your pattern for validation is correctly set up to handle the length of the description. By using Pattern="^.{3,200}$", you're ensuring that the input text adheres to the specified character limits.

Final Code Example

Here’s how your DataGridColumn should look after implementing the changes:

Conclusion

Binding a variable in a TextEdit inside the EditTemplate of a Blazorise DataGrid is not as scary as it seems! By simply listening to the TextChanged event and updating the context accordingly, you can ensure your data updates as expected.

With these modifications, your DataGrid will allow users to edit and save descriptions effectively. Happy coding, and don't hesitate to explore further with Blazor and Blazorise!
