With this function you can retrieve the string data associated with an item in a grid list. This is not the text that is displayed on the item, but an internal string that you can use to hold extra information about the item.
Note: This function will only work after you set the item's text using guiGridListSetItemText!

Syntax

var guiGridListGetItemData ( element gridList, int rowIndex, int columnIndex )

OOP Syntax Help! I don't understand this!

Method: GuiGridList:getItemData(...)


Required Arguments

  • gridList: the grid list containing the item you're interested in
  • rowIndex: the row index of the item
  • columnIndex: the column index of the item

Returns

Returns the item data of the specified item if succesful, false if one of the arguments was invalid.

Example

This example displays a random item data from the gridlist. 

function clientsideResourceStart ()
    local numberList = guiCreateGridList ( 0.80, 0.10, 0.15, 0.60, true )
    local column = guiGridListAddColumn ( numberList, "Column Title", 0.85 )
    if ( column ) then
        local row = guiGridListAddRow ( numberList )
        local myItem = guiGridListSetItemText ( numberList, row, column, tostring( math.random(0, 10) ^ 100 ), false, false )
        local myItemData = guiGridListGetItemData ( numberList, row, column )
        outputChatBox ( "My gridlist item data: " .. myItemData )
    end
end
addEventHandler ( "onClientResourceStart", resourceRoot, clientsideResourceStart )
