Excel filter in DateTime? column

Hi. When we use the DateTime? data type in a grid column with null values, there are 2 problems.

1) If the first value in the dataset is null, then the column formatting does not work:



2) And this is critical. If using the Excel filter we select an Blanks (null) values, an error occurs:





Please offer solutions to these issues, especially the second. Thanks.

Hi Costa, 

Greetings from Syncfusion support. 

By default columns type set based on the first record in Grid dataSource but in your case you have null value for first record in Grid. So, we suggest you to set type for those column in Grid.   

Refer the help documentation. 


Please let us know if you need further assistance on this.

Thank you for answering the first part of the question. Have you noticed that the question consists of two parts? "2) ...If using the Excel filter we select an Blanks (null) values, an error occurs" What about the second part? The second part is the main one.
To make it easier to understand, an example is attached to the question. See the attachment.
