We're using a GridAttachmentColumn to upload stuff within a databound Grid.

How can I hide this column in View mode and only display it when an item is in Edit mode? We also use InPlace editing and I suppose we would need to rebind the grid. Possible to hide the column via JavaScript?

Hi,

Please try the following code snippet to show the GridAttachmentcolumn only in edit mode.

C#:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
   if (e.Item is GridDataItem && !e.Item.IsInEditMode)
    {
        GridDataItem DataItem = (GridDataItem)e.Item;
        DataItem ["AttachmentColumnUniqueName"].Visible = false;     
    }
}

Thanks,
Shinu.

Hi Shinu,

This hides the data of the column but not the column itself.

Before doing this: DataItem ["AttachmentColumn"].Visible = false; the RadGrid looks like so:
AttachmentColumn    TitleColumn         CommentColumn
Document.docx       My document         This is a comment
Excel.xlsx          My File             Another comment

After hiding the AttachmentColumn I get this grid:
AttachmentColumn    TitleColumn           CommentColumn
My document         This is a comment
My File             Another comment

The grids' data is shifted one to the left. How would I also delete the column header (just clearing the HeaderText doesn't work - the column still exists)?

Hi,

Please hide the Header cell as follows.

C#:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridHeaderItem)
    {
        GridHeaderItem HeaderData = (GridHeaderItem)e.Item;
        HeaderData ["AttachmentColumnUniqueName"].Visible = false;
    }
}

Thanks,
Shinu.

Perfect Shinu, now I only need to find out whether the item belonging to the headeritem is in edit mode as I can't do && !e.Item.IsInEditMode on the HeaderItem, as it never is in edit mode.

(again because I only want to hide the Attachment column as well as its header in View mode, in edit mode I want to use it)

Got it.
var headerData = e.Item as GridHeaderItem;
if (headerData != null)
{
    headerData["AttachmentColumnUniqueName"].Visible = grdIdeaAttachments.EditIndexes.Count != 0;
}

I just have to check whether there are any EditIndexes, that way I know whether I am in edit mode. Thanks!
