Column alignment breaks for custom columns

[Andreas]

I have an issue where column alignment breaks after the 10th grid row for custom columns. There is no difference in the behaviour during page load and during consecutive file explorer updates.

The name and size columns are aligned correctly, but the custom columns are incorrectly aligned. See provided screenshot. The custom columns are added like this (server side)

var createdDateColumn = new GridTemplateColumn
{
            HeaderText = GlobalResources_Projects.FileExplorer_CreatedDate,
            SortExpression = "CreatedDate",
            UniqueName = "CreatedDate",
            DataField = "CreatedDate",
};
createdDateColumn.ItemStyle.HorizontalAlign = HorizontalAlign.Left;
fileExplorer.Grid.Columns.Add(createdDateColumn);

I've tried to fix the issue by manually setting the column width to fix sizes on the server side, to no avail. This is done for all columns, including the standard 'name' and 'size'.

GridColumn column = fileExplorer.Grid.Columns.FindByUniqueNameSafe(name);
column.HeaderStyle.Width = Unit.Pixel(width);
column.ItemStyle.Width = Unit.Pixel(width);

Do you have any idea what the problem is?

Hello Andreas,

We are aware of such problem in the earlier version of the RadGrid control (the RadFileExplorer uses RadGrid in its right panel) but it is already fixed. Could you please update to the recent version and you should not experience the same problem?
In case that the update do not help, could you please rework my test project in order to show the issue, open a new support ticket and send it back? I will check it and do my best to provide a working solution as soon as possible.

Kind regards,
