[Help/GUI] Store, read and use data from a gridlist

[Mittell Buurman]

I'm making a GUI where you can store radio frequencies, But where can I store the values Clientside?

It sets the items into the gridlistn, but when I close the window and reopen it, everything is gone.

[Castillo]

You can store them on a lua table, then when re-open the GUI, loop the table and insert them into the grid list.

I think he wants it so the people who use the GUI can go on it and store their own data. And then store that clientside and not in like an sql table.

[Mittell Buurman]

I want it to store clientside, like callum said. But how do you do that?

[Castillo]

You can use client side XML.

I got the XML file made, but now it doesn't read or misses the table, nor does it add rows/values into the gridlist.

  
function setRadioChannel(button, state) 
    local channel = xmlNodeGetChildren(xmlRootTree) 
    if (source == bChanSet) then 
        for k, v in ipairs(channel) do 
        local channelFreq = guiGetText(eChanFreq) 
        local channelDesc = guiGetText(eChanDesc) 
        local row = guiGridListAddRow(gRadioGrid) 
            if channelFreq then 
                guiGridListSetItemText( gRadioGrid, row, colFreq, channelFreq, false, false) 
                guiGridListSetItemData( gRadioGrid, row, colFreq, channelFreq) 
                outputDebugString("channelFreq Read, value " .. tostring(channelFreq) "set to row " .. tostring(row)) 
            end 
            if channelDesc then 
                guiGridListSetItemText( gRadioGrid, row, colDesc, channelDesc, false, false) 
                guiGridListSetItemData( gRadioGrid, row, colDesc, channelDesc) 
                outputDebugString("channelFreq Read, value " .. tostring(channelDesc) "set to row " .. tostring(row)) 
            end 
        end 
    end 
end 
addEventHandler("onClientGUIClick", getRootElement(), setRadioChannel)

Post the full code.

P.S: Never name a function like a native MTA function ( setRadioChannel ), unless you want to replace it.

How you want to load something that doesn't exist? you aren't writting anything on the file, also, you should load them on start, not when you add it.

[Mittell Buurman]

They load from the start don't they?

Im quite new to scripting / xml functions so I'm having some trouble with it.

No, they don't.
