In a javascript function, I want to open the window that is usually opened when the user clicks on the "Assign" button in the lead form.
In the ribbon workbench, I see that the function that is called on the click of Assign is XrmCore.Commands.Assign.assignObjectLegacy, in the library Main_system_library.js.
Is it possible to call this function in javascript?
Doing such things like using internal libraries, calling internal methods are unsupported in Dynamics CRM. Future version of product changes may affect this implementation.
Instead, try to use jQuery to find the button element & invoke the onclick event like $('#assignbuttonid').click(). This is too unsupported because we cannot use DOM manipulation but somewhat ok.
Otherwise I don’t see any alternate supported solution to do this.
Using jQuery is one way to mimic the feature but like Arun said it's unsupported and risk to break in the next update. Instead, I would call a custom action. An action is basically a workflow. You can assign your entity via javascript and it will be supported.
Here is a sample you can use: https://community.dynamics.com/crm/b/nishantranaweblog/archive/2017/05/27/sample-code-to-call-action-using-web-api-in-crm

I have a WinForms app that uses a .NET webbrowser control. What I need to do, is wire up an event on the WinForms side to fire when a value is set (via javascript) in the loaded HTML page. I had success doing this with an onclick event of a button, but I can't seem to get it to work with a custom event. I don't know if this is a limitation in what the browser control can attach to event wise.
So essentially, I need that when a JS function is called in the HTML page and sets a value of a hidden input element (or it could be a regular input that I style to be hidden), I need to know that in WinForms. If it helps, I am using browser flags in this application to emulate IE11 instead of the default IE9 engine. The HTML page loaded is also mine so I can modify it any way needed to make this work properly. I would just use the onclick events of the buttons, but this is a gmaps integration where there can be upwards of 2000 buttons generated (one per marker placed) so it seems like a huge waste of resources to wire up 2000 onclick events when any of those button clicks only modify 4 input fields with the data I care about.
This project happens to be in VB.NET, but C# solutions would be fine as well. They can be transcoded or if the solution uses C# specific features, we can move this to a separate DLL and reference it.
After spending a lot of time on this today, I found a solution. It isn't a direct solution to the problem I posted, but it got me to where I needed to be. I am still interested in an answer to the original problem if anyone has one, but for now, what I found I could do was to create a class in .NET that I could assign to the ScriptingObject of the browser control and then call window.external.myFunctionName, where myFunctionName is a function within the .NET class. This works great for my specific problem, but would not work if I didn't also control the HTML page I was consuming with the browser. That is why I am still interested in alternate solutions if anyone has one. Thanks.
I have a Javascript code registered onSave of record. I need to check whether the save operation is happening by clicking on Save button or saving programmatically like Xrm.Page.data.entity.save().
Do we have a JScript code to get the source control of the event, means event generator?
Without this information on the context why not set a variable in the JavaScript function where you call entity.save explicitly? You can then check this from any other JavaScript function to determine "context". It's a bit of a hacky global flag but it'll do the job.
If you need to get a hold of this "context" within a plugin you can create a hidden attribute on the form setting submitMode('always') that you set prior to save within the custom JavaScript and reset on load.
Have you tried something like that: https://community.dynamics.com/product/crm/f/117/t/58773.aspx
How can we know which javascript method is called and where it is defined? (When methods are attached dynamically)
Let us consider situation where JQuery Bind method is used to bind an event.
If I see control in FireBug with FireQuery, I can see events=Object{click =} handle=function()
But I don't know which method is attached with click event.
Is there any way to detect this method is being called from this file?
For 3-4 files, I could search. but for large number of files with heavy code, it is difficult to search.
You can use console.trace() but this only works within the function
You may also find the question and answer here useful:
what events are bound?
You should be able to click on the "function()" and firebug 1.6 will navigate to the source.
just mouseover the event handler function in firebug (if fireQuery is installed)

I have a custom built ajax [div] based dynamic dropdown.
I have an [input] box which; onkeyup, runs an Ajax search which returns results in divs and are drawn back in using innerHTML. These divs all have highlights onmouseover so, a typical successful search yields the following structure (pardon the semi-code):
[input]
[div id=results] //this gets overwritten contantly by my AJAX function
[div id=result1 onmouseover=highlight onclick=input.value=result1]
[div id=result2 onmouseover=highlight onclick=input.value=result2]
[div id=result2 onmouseover=highlight onclick=input.value=result2]
[/div]
It works.
However, I'm missing the important functions behind regular HTML elements. I can't keyboard down or up between "options".
I know javascript handles keyboard events but; I haven't been able to find a good guide. (Of course, the follow-up question will end up being: can I use <ENTER> to trigger that onclick event?)
What you need to do is attach event listeners to the div with id="results". You can do this by adding onkeyup, onkeydown, etc. attributes to the div when you create it or you can attach these using JavaScript.
My recommendation would be that you use an AJAX library like YUI, jQuery, Prototype, etc. for two reasons:
It sounds like you are trying to create an Auto Complete control which is something most AJAX libaries should provide. If you can use an existing component you'll save yourself a lot of time.
Even if you don't want to use the control provided by a library, all libraries provide event libraries that help to hide the differences between the event APIs provided by different browsers.
Forget addEvent, use Yahoo!’s Event Utility provides a good summary of what an event library should provide for you. I'm pretty sure that the event libraries provided by jQuery, Prototype, et. al. provide similar features.
If that article goes over your head have a look at this documentation first and then re-read the original article (I found the article made much more sense after I'd used the event library).
A couple of other things:
Using JavaScript gives you much more control than writing onkeyup etc. attributes into your HTML. Unless you want to do something really simple I would use JavaScript.
If you write your own code to handle keyboard events a good key code reference is really handy.
Off the top of my head, I would think that you'd need to maintain some form of a data structure in the JavaScript that reflects the items in the current dropdown list. You'd also need a reference to the currently active/selected item.
Each time keyup or keydown is fired, update the reference to the active/selected item in the data structure. To provide highlighting information on the UI, add or remove a class name that is styled via CSS based on if the item is active/selected or not.
Also, this isn't a biggy, but innerHTML is not really standard (look into createTextNode(), createElement(), and appendChild() for standard ways of creating data). You may also want to see about attaching event handlers in the JavaScript rather than doing so in an HTML attribute.
My coworker and I have encountered a nasty situation where we have to use an active X control to manipulate a web camera on a page.
Is it possible to assign a javascript event handler to a button in the active x control so that it would fire an action on the page when clicked, or do we have to create a button on the html page itself that manipulates the Active X Control and then can fire any necessary actions on the page?
Please just use an existing ActiveX control. Like Flash or Silverlight. Flash has built-in webcam support and is controllable via JavaScript. Silverlight doesn't have built-in camera support, but it's JavaScript integration is fantastic.
If you must write your own then fret not, it is trivial to get it to interact with JavaScript. You just have to expose the IDispatch interface.
For events, you need to learn about Connection Points.
Yes! You can throw events in C++/ActiveX land which makes the JavaScript code run an event handler function. I was even able to make an entire invisible ActiveX control (same color as page background) with no buttons or visual feedback that did all of its GUI work through JavaScript and CSS.
edit: Frank's advice is right on. Here's the link on scripting events.
My strategy was to call a C++ function called MyUpdate (which implements IConnectionPoint) when I wanted to force updates in the browser.
(Also, I made sure to pump Windows messages in the Fire_MyUpdate method because sometimes JavaScript code would call back into C++ land by calling methods on the ActiveX control; this avoids freezing up the browser and ensures that the JavaScript GUI stays responsive, e.g. for a Cancel button.)
On the browser side, the JavaScript code has the global variable referencing the object, followed by "::", followed by the method name:
function Uploader::MyUpdate()
{
// ... code to fetch the current state of various
// properties from the Uploader object and do something with it
// for example check Uploader.IsActive and show or hide an HTML div
}
