checkbox column disappear after column chooser uncheck all action

[pk]

Hi,

I'm having a bug using column chooser + selection

Piece of code:

<ejs-grid id="my-grid" load="loadChild" showColumnChooser="true" toolbar="@( new List<object>() {"ColumnChooser"})" 

                          allowSelection="true" >

                    <e-grid-selectionsettings mode="Row" type="Multiple" checkboxOnly="true" checkboxMode="Default"></e-grid-selectionsettings>

                    <e-grid-columns>

                        <e-grid-column type="checkbox" width="35" maxWidth="35" minWidth="35" ></e-grid-column>

                        <e-grid-column field="rowguid" visible="false" showInColumnChooser="false" width="35" ></e-grid-column>

                        <e-grid-column field="reference" headerText="Reference" width="120" template="#referenceTemplate"></e-grid-column>

                        <e-grid-column field="something" headerText="Something" width="120"></e-grid-column>

[...]

Problem:

If the user 

1. opens the column chooser

2. uncheck the "Select All"

3. selects as many columns as he wants (but not hit the "Select All" checkbox)

4. hits ok

the column disposition ends up being incongruent and wrong. (its hiding the header and leaving the tds without the check.. and moving the other columns headers to the right..)

The checkbox column should be shown always (regardless of the column chooser)

Can you please guide me to fix this issue?

thanks

Hi,

About and checked with our end and grid scrolls are working fine

I think you do not understand the issue. I never talked about scrolls.

I will re-explain the matter, because the problem also happens on your code, I've just tested it.

Do you see the checkbox column? on the left? the column to select rows and delete them on your example.

Well, please, try to follow these steps:

1. open the column chooser.

2. click the "Select All" option to unselect all of the columns.

3. select one column (Freight for example...)

4. hit ok.

And you will see that the SELECT/CHECKBOX/TAG column (or whatever you want to call it) disappears and then I cannot select/check/tag rows to delete.

That is the problem, not the scroll, not anything else.

I repeat myself: The checkbox column should be shown always (regardless of the column chooser)

Hope I made myself clear and now you get the issue.

Try it on your code because it's also failing, there's no need to share mine in this case.

thanks
