Coloring column in an ALV tree

Hi all,

What I want to do is set background color for columns in a tree-view ALV(class cl_gui_alv_tree). However no matter how I set the field EMPHASIZE in the fieldcatalog internal table, the display of the ALV tree keeps unchange. Anyone can help me on this?

Thanks,

Chen Chang

    Hi Judith,

    Thank you for your reply. While, can you tell me how to populate the stype parameter in the first piece of your code, because I even don't know what's the value of it. Or you may paste the completed code for it.

    Thanks,

    Chen Chang

    Hi,

    <b>If u want to change the node colr in ALV tree do as follows</b>

    • Adding Root Nodes for the tree.

    • Key:

    • NODE_KEY, RELATKEY, RELATSHIP, HIDDEN, DISABLED, ISFOLDER, N_IMAGE,

    • EXP_IMAGE, <b>STYLE</b>, LAST_HITEM, NO_BRANCH, EXPANDER, DRAGDROPID, TEXT

    perform f9101_node_list using: '1' 'ROOT' '' '' '' c_x '' '' '' '' ''

    c_x '' text-003.

    • Adding subitems for the root node.

    perform f9101_node_list using:

    • Material Details

    'MATRL' '1' '' '' '' '' '' '' '' '' '' '' ''

    text-001,

    • Document Details

    'DOCU' '1' '' '' '' '' '' '' '' '' '' '' ''

    text-002.

    form f9101_node_list using value(pnodekey)

    value(prelatkey)

    value(prelatship)

    value(phidden)

    value(pdisabled)

    value(pisfolder)

    value(pimage)

    value(pexpimage)

    value(pstyle)

    value(plastitem)

    value(pnobranch)

    value(pexpander)

    value(pdragdropid)

    value(ptext).

    w_nodes-node_key = pnodekey.

    w_nodes-relatkey = prelatkey.

    w_nodes-relatship = prelatship. "Natural number

    w_nodes-hidden = phidden.

    w_nodes-disabled = pdisabled.

    w_nodes-isfolder = pisfolder.

    w_nodes-n_image = pimage. "Icons / embedded bitmap

    w_nodes-exp_image = pexpimage. "Icons / embedded bitmap

    <b> w_nodes-style = pstyle.</b> w_nodes-last_hitem = plastitem. "Tree Control: Column Name / Item

    "Name

    w_nodes-no_branch = pnobranch.

    w_nodes-expander = pexpander.

    w_nodes-dragdropid = pdragdropid.

    w_nodes-text = ptext.

    append w_nodes to i_nodes.

    endform. " f9101_node_list

    Try changing the style so that u can change the column color.

    If u want that in ALV grid

    1. different color in line of alv

    2. Coloring Cells/rows in ALV Grid.

    Got this from forum
