    I tried to change the format of Size column in the FileExplorer Grid control. e.g., 1,234 KB, etc. with DataFormatString if possible, such as


    sc = (GridBoundColumn)e.Column;

    sc.DataFormatString = "{0:###,### KB}";

    However, I couldn't find a way to modifiy it. Even, I tried to make it invisible using

    It makes header part disappeared, but it still shows the size value in the data grid.

    I also tried to use Grid ItemDataBound as follows, it doesn't work. I found after fired RadFileExplorer1_Grid_ItemDataBound, the RadFileExplorer1 refreshes whole grid again and make it as it was, i.e., before my rendering is applied.



    void RadFileExplorer1_Grid_ItemDataBound(object sender, GridItemEventArgs e)


    if (e.Item is GridDataItem)


    GridDataItem item = (GridDataItem)e.Item;

    item["Size"].Text = string.Format("{0:###,### KB}", item["Size"].Text);



    As far as what i've successed in the format change is just an alignment as like:



    void RadFileExplorer1_Grid_ColumnCreated(object sender, GridColumnCreatedEventArgs e)


    RadFileExplorer1.Grid.Columns[1].ItemStyle.HorizontalAlign = HorizontalAlign.Right;

    RadFileExplorer1.Grid.Columns[1].ItemStyle.Width = 30;

    RadFileExplorer1.Grid.Columns[1].HeaderStyle.HorizontalAlign = HorizontalAlign.Center;

    RadFileExplorer1.Grid.Columns[1].HeaderStyle.Width = 30;

    Hi Tom,

    The file explorer's Grid is using client databinding. This means that none of the server-side databinding events will have any effect on the control. The grid is bound in the browser each time you change the file explorer's current folder. At the moment it is not possible to modify the default grid columns (name and size) on the server.

    However, you can create a custom grid column and display the file size there. We have a similar example in our online demos - As I said it is not possible to hide the size column, but you can resize it to 1 px, which will make it practically invisible and leave only your custom size column:

    GridColumn SizeColumn = RadFileExplorer1.Grid.Columns.FindByUniqueNameSafe("Size"); 
    SizeColumn.ItemStyle.Width = Unit.Pixel(1); 
    SizeColumn.HeaderStyle.Width = Unit.Pixel(1);

    Is there allready a solution for this issue? Becaues i think it is not a neat solution to resize the column and add a custom grid column.
