I'm trying to change allowedit value on a single field but can't get into it.
This is my actuall code but I get error:
Okay did rebuild the models and it's fine
[ExtensionOf(formStr(ProdParmReportFinished))]
final class ProdParmReportFinishedWG_Extension
{
public void init()
{
next init();
ProdTable prodTable;
select firstOnly RecId from prodTable
where prodTable.InventRefType != InventRefType::None
&& prodTable.ProdId == prodTable.InventRefId
&& prodTable.ProdStatus != ProdStatus::ReportedFinished;
prodParmReportFinished_ds.object(fieldNum(ProdParmReportFinished, EndJob)).allowEdit(prodTable.RecId != 0);
}
}
if you are working with extension try something like this
[PostHandlerFor(formStr(YourForm), formMethodStr(YourForm, YourMethod))]
public static void YourForm_xxx(XppPrePostArgs args)
{
FormRun sender = Args.getThis();
sender.control(sender.controlId(formControlStr(YourForm, YourDatasource_Field))).allowEdit(false);
}
With the right click and select copy event handler method the correct structure of the method is copied to you, then you enter your code

Ok I did it. It works fine. Thanks for help. Here is my code. Now I only need to call my command button in a differend form to disable it and create a info there. Anyone could look about it ? In my code I got reference errors.
[ExtensionOf(formdatasourcestr(ProdTableListPage, ProdTable))]
final class ProdParmReportFinishedActiveWG_Extension
{
public int active()
{
int ret;
next Active();
{
ProdTable tableBuffer = this.cursor();
ProdTable prodtable;
if(tableBuffer.ProdId == tableBuffer.CollectRefProdId
&& tableBuffer.ProdStatus != ProdStatus::ReportedFinished)
{
select firstonly RecId,ProdId from ProdTable where
ProdTable.CollectRefProdId == tableBuffer.ProdId
&& ProdTable.Prodstatus != ProdStatus::ReportedFinished
&& tableBuffer.RecId != prodtable.RecId;
{
Global::info(strFmt("%1 , %2",
prodtable.prodid, prodtable.recid));
// FormButtonControl mybutton = this.FormRun().design().controlname(formControlStr(ProdParmReportFinished, Ok)) as FormButtonControl;
// mybutton.enabled(false);
}
}
else
{
Global::info(strFmt("%1 , %2, %3, %4",
tableBuffer.prodid, tableBuffer.CollectRefProdId, tableBuffer.InventRefType, tableBuffer.ProdStatus));
}
}
return ret;
}
}
"I want to use this code everytime user changes his actual row but instead it runs just once and apply to all my rows."
Use the selectionChanged() method instead of active().
In fact most use cases where you think you should use active(), you're probably looking for selectionChanged() (or the OnSelectionChanged event for handlers) instead.
I have a Xamarin.Form MainPage:ContentPage with a ToolbarItems Bar on top. The toolbar items are bound to my ViewModel like so:
<ToolbarItem Text="Sync" Command="{Binding ReloadCommand}" >
</ToolbarItem>
The availability of the Item depends on some logic:
private bool canReloadExecute(object arg)
{
bool result = (!IsReloading && (App.GetPersistentSetting("DeviceID") != "") && (App.GetPersistentSetting("BuildingID") != ""));
return result;
}
There is a separate dialog controlling the DeviceID and BuildingID on a different settings page. Once any of those ids is entered it is persistently stored away
App.SetPersistentSetting("DeviceID",value);
Problem is, that the menu items don't change their appearance once my code uses popAsync() to return to the Main page. I need to restart my app to see the changes. According to the debugger, canReloadExecute isn't called. Why this?
What I tried to work around this issue is to force a refresh in the MainPage's OnAppearing method like this:
public void RefreshToolbarItems()
{
TestApp.ViewModels.MainViewModel mvm = (TestApp.ViewModels.MainViewModel)BindingContext;
mvm.RefreshToolbarItems();
}
... and in the ViewModel:
public void RefreshToolbarItems()
{
OnPropertyChanged("BuildingScanCommand");
OnPropertyChanged("ReloadCommand");
}
but this code runs through but changes nothing, while the Debugger shows that the routine is indeed firing the events, they seem to go nowhere.
Any ideas how I can get my menu going?
Edit 1: "Show command initalization"
I am not shre what specifically you mean, but here is the whole code dealing with the command:
private ICommand _reloadCommand;
public ICommand ReloadCommand => _reloadCommand ?? (_reloadCommand = new Command(ExecuteReloadCommand, canReloadExecute));
private bool _isReloading = false;
public bool IsReloading
{
get => _isReloading;
set
{
_isReloading = value;
((Command)_reloadCommand).ChangeCanExecute();
OnPropertyChanged(nameof(ReloadCommand));
}
}
private bool canReloadExecute(object arg)
{
bool result = (!IsReloading && (App.GetPersistentSetting("DeviceID") != "") && (App.GetPersistentSetting("BuildingID") != ""));
return result;
}
private async void ExecuteReloadCommand(object obj)
{
IsReloading = true;
// Some code ...
IsReloading = false;
}
The goal is to disable the command, if either the command handler is already running, or if the configuration of DeviceID and/or BuildingId hasn't been done yet.
The enable/disable does almost work, if I set the DeviceId and BuildingId, and restart the app, the command is properly enabled or disabled. It doesn't work, however, if I set the Ids in a sub-page and return to the main page.
meanwhile I came to the conclusion, that firing onPropertyChange obviously doesn't make the command check its canReloadExecute. So the question is, how do I trigger this?
I finally solved the issue myself, this code works nicely for me:
public void RefreshToolbarItems()
{
((Command)BuildingScanCommand).ChangeCanExecute();
((Command)ReloadCommand).ChangeCanExecute();
}
I'm a newbie in ASP.NET and I'm stuck at populating a List when web page load.
I have a class that, when instantiated, will add some objects into a list. This class has a method to add objects to a list (I made this a method because I need to reuse it later). This is the code for this class:
public class Task()
{
private List<ObjectA> objList;
....// other variables and properties
public Task()
{
objList = new List<ObjectA>();
// first add 2 obj into the list
AddObjToList(objList);
AddObjToList(objList);
}
public void AddObjToList(List<ObjectA> objList)
{
bool exist = false;
ObjectA obj = new ObjectA(); // each obj has unique properties
foreach(var o in objList)
{
if(o.objName == obj.objName)
{
exist = true;
break;
}
}
if(!exist)
{
objList.add(obj);
}
}
}
I have a web page that, when loaded, I want it to populate the objList with 2 starting objects. This is my code behind for the web page:
protected void Page_Load(object sender, EventArgs e)
{
Task newTask = new Task();
// the following label control is to check the number of
// elements in the List
lblMSG.Text = newTask.getObjList.Count.ToString();
}
The problem is, when I run in debug mode, the list is populated with 2 objects just as I wanted. But when not in debug mode, when the page loaded, the label showed that the list has only 1 object. I tried to call the new Task() with isPostBack but the result is the same. What did I do wrong? What could I do to make it work?
I am trying to pass an ArrayList to a fragment as arguments but the argument seems to be empty.
This is my code of the mainActivity where I create and launch the fragment, which btw works.
ArrayList<HashMap<String, String>> myeventListRefImages; //has data
imageFragment = new ImageMyEventRefFragment();
fragmentManager.findFragmentById(fragmentId);
if (findViewById(R.id.fragment_image) != null) {
if (savedInstanceState != null) {
return;
}
getIntent().putExtra("mERImageList", myeventListRefImages); //working
Bundle bundle = new Bundle(); //doesn’t work
bundle.putSerializable("mERImageList", myeventListRefImages);//doesn’t work
imageFragment.setArguments(bundle);
[…]
}
So far, I only get to manage it with putExtra but in that case, the extra never seems to be empty later on which is kind annoying in case I want to skip the if argument :(
That’s the code of my fragment:
public void onStart() {
super.onStart();
Bundle args = getArguments();//doesn’t work //empty at all
Bundle extras = getActivity().getIntent().getExtras();//works
if (args != null) {
System.out.println("Args!");
}
}
Any idea? I event cant debug the fragment to check the value of the getArugments comment there the app just crashes, but when I run it normally I can use System out commands.
I'm implementing a DynamicItemStart button inside a Menu Controller. I'm loading the dynamic items for this button when Visual Studio starts. Everything is loaded correctly so the initialize method is called an I see all the new items in this Dynamic button. After the package is completely loaded I want to add more items to this Dynamic button, but since the package is already loaded the initialize method is not called again and I cannot see the new items in this Dynamic button. I only see the ones that were loaded when VS started.
Is there any way that I can force the update of this Dynamic button so it shows the new items?. I want to be able to update the VS UI after I added more items but outside the Initialize method.
The implementation I did is very similar to the one showed on this msdn example:
http://msdn.microsoft.com/en-us/library/bb166492.aspx
Does anyone know if an Update of the UI can be done by demand?
Any hints are greatly appreciated.
I finally got this working. The main thing is the implementation of a derived class of OleMenuCommand that implements a new constructor with a Predicate. This predicate is used to check if a new command is a match within the DynamicItemStart button.
public class DynamicItemMenuCommand : OleMenuCommand
{
private Predicate<int> matches;
public DynamicItemMenuCommand(CommandID rootId, Predicate<int> matches, EventHandler invokeHandler, EventHandler beforeQueryStatusHandler)
: base(invokeHandler, null, beforeQueryStatusHandler, rootId)
{
if (matches == null)
{
throw new ArgumentNullException("Matches predicate cannot be null.");
}
this.matches = matches;
}
public override bool DynamicItemMatch(int cmdId)
{
if (this.matches(cmdId))
{
this.MatchedCommandId = cmdId;
return true;
}
this.MatchedCommandId = 0;
return false;
}
}
The above class should be used when adding the commands on execution time. Here's the code that creates the commands
public class ListMenu
{
private int _baselistID = (int)PkgCmdIDList.cmdidMRUList;
private List<IVsDataExplorerConnection> _connectionsList;
public ListMenu(ref OleMenuCommandService mcs)
{
InitMRUMenu(ref mcs);
}
internal void InitMRUMenu(ref OleMenuCommandService mcs)
{
if (mcs != null)
{
//_baselistID has the guid value of the DynamicStartItem
CommandID dynamicItemRootId = new CommandID(GuidList.guidIDEToolbarCmdSet, _baselistID);
DynamicItemMenuCommand dynamicMenuCommand = new DynamicItemMenuCommand(dynamicItemRootId, isValidDynamicItem, OnInvokedDynamicItem, OnBeforeQueryStatusDynamicItem);
mcs.AddCommand(dynamicMenuCommand);
}
}
private bool IsValidDynamicItem(int commandId)
{
return ((commandId - _baselistID) < connectionsCount); // here is the place to put the criteria to add a new command to the dynamic button
}
private void OnInvokedDynamicItem(object sender, EventArgs args)
{
DynamicItemMenuCommand invokedCommand = (DynamicItemMenuCommand)sender;
if (null != invokedCommand)
{
.....
}
}
private void OnBeforeQueryStatusDynamicItem(object sender, EventArgs args)
{
DynamicItemMenuCommand matchedCommand = (DynamicItemMenuCommand)sender;
bool isRootItem = (matchedCommand.MatchedCommandId == 0);
matchedCommand.Enabled = true;
matchedCommand.Visible = true;
int indexForDisplay = (isRootItem ? 0 : (matchedCommand.MatchedCommandId - _baselistID));
matchedCommand.Text = "Text for the command";
matchedCommand.MatchedCommandId = 0;
}
}
I had to review a lot of documentation since it was not very clear how the commands can be added on execution time. So I hope this save some time whoever has to implement anything similar.
The missing piece for me was figuring out how to control the addition of new items.
It took me some time to figure out that the matches predicate (the IsValidDynamicItem method in the sample) controls how many items get added - as long as it returns true, the OnBeforeQueryStatusDynamicItem gets invoked and can set the details (Enabled/Visible/Checked/Text etc.) of the match to be added to the menu.
