    Hi,

    I have a combo box column within a grid and one of it’s values is 0. When I load data into the grid, the combo box option with a 0 value is not pre-selected when one of the rows has that value.

    I am using angular 7.

    Hope you can provide assistance on this.

    Thanks!

    I just want to add that it only happens when I add a blank option in the combobox with a null value.

    Thanks!

    Hello geromelouie,

    Could you provide us with one simple example that demonstrates your case?
    I tested this example and it seems to work fine:

    I look forward to hearing from you.

    Hi Hristo,

    My case scenario is I have a combo box column inside a grid. Then the combo box has the following values: (value: null, label: ”}, {value: 0, label: ‘Option 0’}, {value: 1, label: ‘Option 1’}. Now if the column value is equals to 1, Option 1 gets selected as expected. However, when the column has a value 0, the option with the null value gets selected instead of the option with the 0 value. I think this has to do with typescript treating 0 as null. If I remove the null option, the 0 value gets selected as expected.

    Thanks!

    Hello geromelouie,

    Could you clarify it?
    What is your final goal?
    If you change the position of the null” value in the end, for example, it will be fine.
    Also, you could use the null” value as a string and internally in your code to compare and set the wanted type correctly.

    Best Regards,
