Initial validation of cell editors
I have text field as a cell editor in a grid cell. I want to show the cell as invalid if the value of the textfield is not valid. I have set the text field value using setValue() method. When I call textField.validate() method, it does not work properly as it is validating the raw value which wil be null or "" initially. I can't set the raw value of the text field before it is rendered. Is there a way to validate the text field before it is rendered.
You could try calling the validate method on your FormPanel after it is rendered.
The fields get validated when they are rendered. Assume that there is a default value for a cell. How do I validate it before it is rendered. In this case, the cell editor for that cell is not yet rendered.
