Search result in 2 lists problem

I hope you have the solution for my problem with this Fx.

 

The property of Gallery1:  OnSelect= Set(SelectedValueVar;GalleryProbleem.Selected.InstructieLink)

 

HtmlTextfield hast the property: HtmlText=

Text(If(

    !IsBlank(LookUp(TestLetterTypeEnFormaat;Titel=SelectedValueVar).Arial18);

   Concatenate(LookUp(TestLetterTypeEnFormaat;Titel=SelectedValueVar).Arial18;

   Concatenate(LookUp(TestLetterTypeEnFormaatKopie;Titel=SelectedValueVar).Arial18))))

 

This should do the following:

The selected item sets a value in the Column ‘InstructieLink’.
This value is also available in 2 other lists ( TestLetterTypeEnFormaat + TestLetterTypeEnFormaatKopie) in the column ‘Titel’  This column is available in both lists.

When the value that is set with selectedValueVar is found, the text written in the Column ‘Arial18’ should become visible in the HtmlText field.

So far, I did not succeed ☹

Hi @FZ80,

 

Thank you so much for the clarification, I understand the requirement. I adjusted my original code and added some comments to further explain the functionality:

With(
    //Temp save both LookUp values
    {
        wLookUpMainArial18: LookUp(TestLetterTypeEnFormaat; Titel=SelectedValueVar; Arial18);
        wLookUpCopyArial18: LookUp(TestLetterTypeEnFormaatKopie; Titel=SelectedValueVar; Arial18)
    };
    If(
        //If at least one of the Lists contains a non-blank value, display the text
        !IsBlank(wLookUpMainArial18) || !IsBlank(wLookUpCopyArial18);
        //Coalesce returns the first non-blank value
        Coalesce(wLookUpMainArial18; wLookUpCopyArial18)
    )
)

Hey @FZ80,

 

Very close! The overall structure looks good, the only issue is that we have With scope variables with the exact same name.

 

Instead of adding another wLookUpCopyArial18 give the newly added LookUp a new, unique name such as wLookUpThirdArial18

 

I hope this helps!

Hi @FZ80,

 

Is there a specific reason why you are nesting the Concatenate functions? If you just want to display the text value within that column, the following code will de the trick:

 

 

With(
    //Temp save the look up value
    {wLookUpArial18: LookUp(TestLetterTypeEnFormaat;Titel=SelectedValueVar).Arial18};
    If(
        //If not blank, display the value
        !IsBlank(wLookUpArial18);
        wLookUpArial18
    )
)

 

 

If this solves your question, would you be so kind as to accept it as a solution & give it a thumbs up.

Thanks!

Hi Laurens,

Unfortunately it does not do the job so far. TestLetterTypeEnFormaat.

Concatanate, to be honest wasn't my idea but that of ChatGPT 🙂

In you solution where is the check in the second list TestLetterTypeEnFormaatKopie.

Mybe I missed it as I'am not that experienced in powerapps?

@FZ80 

 

It unfortunately wasn't fully clear what you would like to achieve with the copy list. Should we concatenate both values?

 

In our If() statement we only check whether the main list is blank, so I assumed we only wanted to display that. Would it be possible to provide some additional information about how the copy list should be included? 😊

Thanks for trying to help me with this.

 

The situation is this:

 

After the OnSelect of a Gallery, the selectedValueVar is being set to keep the value of that item that is in the column ‘InstructieLink’ (e.g. Instr1).

 

The formula has to evaluate where this same value can be found in 1 of the 2 Lists (TestLetterTypeEnFormaat or TestLetterFormaatKopie). To find out where it is, the column ‘Titel’ has to be searched by a formula. There is no logic in if it is in List1 or List2 and on which position in the column ‘Titel’.

In the list where the value ( Instr1) is found, the tekst written in the column 'Arial18' should become visible in a HtmlTextfield.

Hope this makes it more clear to you…?

Glad I was able to help @FZ80!

 

Would it be possible to mark my previous comment as the solution. This will improve visibility in case other community members have a similar issue. 😊

Hi Laurens,

With the Fx you gave me, I thought it would be easy to add an extra 3 other lists.

However, I can't find the clue. 

What I thought would work is to add extra lines as indicated in red. And for 3 extra list, I should do this 3 times.

Unforunately this does not work.

Can you help me one more time with this?

Sorry....

 

 

With(
//Temp save both LookUp values. Dit is de goeie formule voor zoeken in 2 lijsten

wLookUpMainArial18: LookUp(TestLetterTypeEnFormaat; Titel=SelectedValueVar; Arial18);
wLookUpCopyArial18: LookUp(TestLetterTypeEnFormaatKopie; Titel=SelectedValueVar; Arial18);

wLookUpCopyArial18: LookUp(TestLetterTypeEnFormaat3; Titel=SelectedValueVar; Arial18)
};

//If at least one of the Lists contains a non-blank value, display the text
!IsBlank(wLookUpMainArial18) || !IsBlank(wLookUpCopyArial18) || !IsBlank(wLookUpCopyArial18) ;
