Request: isnullorempty filter for text field.

Hi,

I would like to have 'isnullorempty' filter for text field on Data Grid. There are 'isnull' and 'isempty' filters but it is not straightforward for non-engineer guys. If we have 'isnullorempty' filter, I think it is very useful. 

Other option, is there any way to customize filter operator by myself so that we can have any filter operation?  

 

Thank you,

Tatsuro Matsumoto.

Hi Tatsuro,

You are correct that this approach will fail with the columnMenu and I have to say that there is no workaround that we can suggest for it. The only option would be to define entirely custom filterUI with the drop down for the operators and a custom input for the filter value:

Hi Konstantin,

 

Thank you for your comment and suggestion of the workaround. I did try your suggested custom operators but it didn't work when I used 'ColumnMenu' for filtering.

 

Please refer to the following sample. 

https://stackblitz.com/edit/react-wryzhc-ya4tcu?file=app%2Fmain.jsx

You can find the custom operator 'Is Null Or Empty' on a text field (e.g. 'Product Name') but the filter button is disabled unless you enter any string in the text input field. Is there any workaround for this?

 

Thank you,

Tatsuro Matsumoto.

Hi Tatsuro,

Thank you for submitting this feature request.

We will monitor the interest in it and act accordingly based on its popularity.

Meanwhile you can define custom filter operators for the Grid through the filterOperators property:

Please note that in order for the Grid to be able use custom operators you will have to include the "text" for the new operators in the messages for the localization. I have created an example demonstrating how you can add "isnullorempty":

Nevertheless, I do agree that adding this as a built-in operator would be beneficial.
