sc = (GridBoundColumn)e.Column;

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

RadFileExplorer1.Grid.Columns.RemoveAt(1);
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.

protected

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:

protected

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;

}

Thanks.

ResolveRootDirectoryAsTree, and ResolveDirectory Overriden functions to display only certain files and certain folders to the user based on their custom security, however this does not prevent Writing, Deleting, Moving, Uploading and copying Folders and files or the context menus.

what I am looking for is a way to enable, and disable the various context menus that would allow the user to Write, Delete, Move, Upload, and copy folders and files based on their custom security. The users security info is stored in custom session variables.
