[HELP] refresh guiGridList with Players?

Hi,

i have created a guiGridList and would like the players are always updated.

If I choose a player disappears always marking.

After updating always disappears My choice and that must not happen?

function refreshGridList() 
  
    if isElement(newGridlist) then 
        guiGridListClear(newGridlist) 
        for id, player in ipairs (getElementsByType ("player")) do  
            local row = guiGridListAddRow(newGridlist) 
            guiGridListSetItemText(newGridlist, row, column, getPlayerName(player), false, false) 
        end 
    end 
end 
  
function createGridList() 
  
    newGridlist = guiCreateGridList(0.50, 0.50, 0.20, 0.30, true) 
    column = guiGridListAddColumn(newGridlist, "Players", 0.85) 
    if (column) then 
        for id, player in ipairs(getElementsByType("player")) do 
            local row = guiGridListAddRow(newGridlist) 
            guiGridListSetItemText(newGridlist, row, column, getPlayerName(player), false, false) 
        end 
    end 
    getGridListTimer = setTimer(refreshGridList, 500, -1) 
    guiGridListSetSortingEnabled(newGridlist, false) 
end 

I hope someone can help me how to truly important to me!

You should update the girdlist when a player joins or leaves, no in an infinite timer.

function refreshGridList() 
     if isElement(newGridlist) then 
        guiGridListClear(newGridlist) 
        for _, player in pairs (getElementsByType ("player")) do 
            local row = guiGridListAddRow(newGridlist) 
            guiGridListSetItemText(newGridlist, row, column, getPlayerName(player), false, false) 
        end 
    end 
end 
addEventHandler("onClientPlayerJoin", root, refreshGridList) 
addEventHandler("onClientPlayerQuit", root, refreshGridList) 
  
function createGridList() 
     newGridlist = guiCreateGridList(0.50, 0.50, 0.20, 0.30, true) 
    column = guiGridListAddColumn(newGridlist, "Players", 0.85) 
    if (column) then 
        refreshGridList() 
    end 
    guiGridListSetSortingEnabled(newGridlist, false) 
end 

Or, you can add rows when a client joins and remove rows when a client disconnects.

You can use this and be sure to replace gridList and column with your.

function updateList(old, new) 
    if eventName == "onClientPlayerJoin"  then 
        local row = guiGridListAddRow(gridList) 
        guiGridListSetItemText(gridList, row, column, getPlayerName(source), false, false) 
    elseif eventName == "onClientPlayerQuit"  then 
        for i=0, guiGridListGetRowCount(gridList) do 
            if guiGridListGetItemText(gridList, i, column) == getPlayerName(source) then 
                guiGridListRemoveRow(gridList, i) 
            end 
        end 
    elseif eventName == "onClientPlayerChangeNick"  then 
        for i=0, guiGridListGetRowCount(gridList) do 
            if guiGridListGetItemText(gridList, i, column) == old then 
                guiGridListSetItemText(gridList, i, column, new, false, false) 
            end 
        end 
    end 
end 
addEventHandler("onClientPlayerJoin", root, updateList) 
addEventHandler("onClientPlayerQuit", root, updateList) 
addEventHandler("onClientPlayerChangeNick", root, updateList) 

Though you need to do -1 for guiGridListGetRowCount as i didn't do this the time i posted this code, it still work anyway.
