Dynamic creation of UIDropDownMenuTemplate

[morkesh]

So currently i'm having a major issue with UIDropDownMenuTemplate, in my project i dynamically create dropdown boxes but my issue is that when i try to change the value of the first one created, the value of the last one created changes instead how can i avoid this?

Just a quick guess:

19    local function OnClick(self)   
20         UIDropDownMenu_SetSelectedID(self, self:GetID())   
21         ErrDB.ErrRdr[i] = self:GetText()   
22     end

yeah that was my first thought aswell :/ but no luck in terms of changing it to dropdownName, this is the "updated" code, which now throws errors about self

	dropdownName = "optionDropdownRedirect"..NumOptions

	dropdownName = CreateFrame("Frame", "optionDropdownRedirect"..NumOptions, CategoryFrame, "UIDropDownMenuTemplate")
	dropdownName:ClearAllPoints()
	dropdownName:SetPoint("TOPLEFT", 320, distanceTop + 4)

	local function dropdownName_OnClick(self)
   		UIDropDownMenu_SetSelectedID(dropdownName, self:GetID())
		ErrDB.ErrRdr[i] = self:GetText()
	end

	local function initialize(self, level)
		local info = UIDropDownMenu_CreateInfo()

		for k,v in pairs(RedirectOptions) do
			info = UIDropDownMenu_CreateInfo()
			info.text = v
			info.value = v
			info.func = function() dropdownName_OnClick() end
			UIDropDownMenu_AddButton(info, level)
		end
	end

	UIDropDownMenu_Initialize(dropdownName, initialize)
	UIDropDownMenu_SetSelectedName(dropdownName, ErrDB.ErrRdr[i])

i fear it's something really simple but i've only just started programming addons after going a year without programming a single thing, so getting back in shape takes time

Ah ... I remember ... multiple dropdown frames. Lovely thingi

Additionally pass the the parent frame with every new button:

function initialize(self, level)   
     local info = UIDropDownMenu_CreateInfo()   
     for k,v in pairs(RedirectOptions) do   
         info = UIDropDownMenu_CreateInfo()   
         info.text = v   
         info.value = v   
         info.arg1 = self
         info.func = OnClick   
         UIDropDownMenu_AddButton(info, level)   
     end   
end

info.arg1 is passed to info.func and can be used for UIDropDownMenu_SetSelectedID() to modify the proper dropdown frame.

function OnClick(self, parentDropdownFrame)   
      UIDropDownMenu_SetSelectedID(parentDropdownFrame, self:GetID())  
end

You sir, saved my day! thanks a thousand for helping me with this, been bashing my head against the wall since yesterday -.-

Oh! while you'r nearby, any idea why

UIDropDownMenu_SetSelectedName(dropdownName, ErrDB.ErrRdr[i])

wont seem to work? ErrDB.ErrRdr contains strings with names exactly matching those of my dropdown

[Duugu]

Hm.

UIDropDownMenu_SetSelectedName(dropdownName, "Raidwarning")

does the job.

Must be something with ErrDB.ErrRdr or the index i.

yeah true, will look into it thanks for the help though!
