AloowEdit is ignored in grouping columns

Hey, 


I have this column definition:

 <GridColumn Field="@nameof(MDefaultText.GroupName)" HeaderText="Gruppe" AllowEditing="false"></GridColumn>

And this edit settings:

<GridEventsRowUpdated="UpdateHandler"TValue="MDefaultText"></GridEvents>

If I now open the edit dialog the property input is readonly, this is correct.
But if I add this grouping settings:
    <GridGroupSettingsColumns="@([nameof(MDefaultText.GroupName)])"></GridGroupSettings>

then the property editor is not readonly anymore.

Thanks for the patience,

We are glad to announce that, we have included the fix for the issue “GridColumn AllowEditing set to false is ignored for grouped columns in dialog edit mode” in our 34.2.5 release.  So please upgrade to our latest version of Syncfusion NuGet package to resolve the reported issue. Please find the NuGet package for latest fixes and features from below.


NuGet : https://www.nuget.org/packages/Syncfusion.Blazor.Grid

Sample: https://blazorplayground.syncfusion.com/rthRjPVSKhVPdHlA

Root Cause
The isEditable method unconditionally returns true for grouped invisible columns, ignoring the AllowEditing property.

Solution Description
The fix ensures that the isEditable() method returns false for grouped columns with AllowEditing=false, which causes the editor cell component to disable the input while still rendering it in the DOM.

We thank you for your support and appreciate your patience in waiting for this release.
