How to pass parameter to Custom Page

[Axal]

Hi guys,

In my Model-driven app, I've added a command button to which will open Custom Page. A Javascript has been created, something like this :

function openPageInlineWithContext(selectedItems)
{
    var selectedItem = selectedItems[0];

    if (selectedItem) {     
        let pageInput = {
            pageType: "custom",
            name: "new_accountpage_d32ca",
            entityName: selectedItem.TypeName,
            recordId: selectedItem.Id,
        };
        let navigationOptions = {
            target: 1
        };
        Xrm.Navigation.navigateTo(pageInput, navigationOptions)
            .then(
                function () {
                    // Handle success
                }
            ).catch(
                function (error) {
                    // Handle error
                }
            );
    }
}

Which in one of the lines is this code -> recordId: selectedItem.Id

It is mentioned that is to "handle" the record id to be passed to Custom Page when it is called.

Now in my Custom Page, I have this code in OnStart method :

Set(RecordItem,
    If(IsBlank(Param("recordid")),
        Blank(),
        LookUp(Accounts, Account = GUID(Param("recordid")))
    )
)

But if I tested this Param("recordid") in some Label inside my app, it always empty. May I know how to pass the record from Model-driven View to Custom Page ?

The command button in the main grid, when setting the Javascript, I put the parameter to "SelectedControlAllItemReferences"

Is this option wrong for me to choose ? or is there anything else that make the record id is not going to my Custom Page ?

Thanks

Hi @Axal ,

Have you looked at the PowerFX formulas to navigate?  Some are still in preview but might simplify your code.  https://docs.microsoft.com/en-us/power-apps/maker/model-driven-apps/page-powerfx-in-model-app 

Not sure why the parameter is blank based on your code above though on the custom page.

Hi,

Yes, in some part I have read the document, although to be honest no fully understood all of it. As for the link you gave me, is about Navigate, unfortunately it looks like not what I need, as I really need to pass information from Model-driven first, before some processes happened in Custom Page.

In one of those doc actually there is 1 page interest me - Navigating to and from a custom page in your model-driven app using client API - Power Apps | Micros...

Especially in this section -> Navigating to and from a custom page in your model-driven app using client API - Power Apps | Micros...

It is talked about :

1. Create a web resource of type JScript and update the name parameter to be the logical page name. Add the following code to the web resource. (Same as what I already did)

2. Customize the table ribbon CommandDefinition for OpenRecordItem to call the function above and include the CrmParameter with the value SelectedControlSelectedItemReferences.

    <JavaScriptFunction FunctionName="run" Library="$webresource:cr62c_OpenCustomPage">
        <CrmParameter Value="SelectedControlSelectedItemReferences" />
    </JavaScriptFunction>

This no 2 is the one that I'm lost. Anyone can help what to do for this step no 2 ?

The next step is again I have done it ->

3. In the custom page, override the App's OnStart property to use the Param function to get the recordId and lookup record.

Thanks

Hi @Axal ,

I just reviewed this video, hopefully this helps...

Hi,

Some updates, turned out there is a typo error with my code in Custom App - OnStart method ->

Set(RecordItem,
    If(IsBlank(Param("recordid")),
        Blank(),
        LookUp(Accounts, Account = GUID(Param("recordid")))
    )
)

whereby the "recordid",  supposed to be followed what's typed in Web Resources -> "recordId"

(the "I" should be uppercase, case sensitive)

Anyway, the Custom App shows something, but it looks still incorrect since it always show the 1st record. Even when I didn't select any row, when I click the button, Custom Page showing Account - 1st record.

Now I'm wondering if this Parameter setup in command grid is the problem ? ->

Anyone can help ?

Thanks

Hi guys,

Another updates, if I change the Parameter to be SelectedControlSelectedItemRefrence, ->

My Custom Page able to show the correct record when I select a record in the view grid. However when none selected, the Custom Page is not shown.

I only think, this could be handle without Ribbon Workbench, only I couldn't find where should I correct this. Any suggestion ?

Thanks

Hey @Axal !

I don't know if you're still facing problems, but here's my piece of advice:

1. As a rule of thumb, always use PrimaryControl to pass the correct context from the Model Driven app to the Custom page:

Then, in your JavaScript, you can get the record's GUID: like this:

let itemId = PrimaryControl.data.entity.getId().replace("{", "").replace("}","")

2. To control the visibility of your command, I would also recommend using the Power Fx capabilities if possible:

Here's the docs for your reference: Use Power Fx with commands - Power Apps | Microsoft Learn

@andres_b  how would this look then in the final JS file?

[andres_b]

@NativeNass_ ,

If we use the original's post code, it would look like this:

function openPageInlineWithContext(PrimaryControl)
{
    let itemId = PrimaryControl.data.entity.getId().replace("{", "").replace("}","")
        let pageInput = {
            pageType: "custom",
            name: "new_accountpage_d32ca",
            recordId: itemId,
        };
        let navigationOptions = {
            target: 1
        };
        Xrm.Navigation.navigateTo(pageInput, navigationOptions)
            .then(
                function () {
                    // Handle success
                }
            ).catch(
                function (error) {
                    // Handle error
                }
            ); 
}

Hi @andres_b  

Thanks for the quick response.

When I load in this file, the button doesn't even do anything anymore

I have been going crazy all day with the same issue.

Don't really know what to do anymore
