Auto Populating Gallery

(0) Share

Report

Posted on by aleisure99

Hello,

I have a gallery that leads to a sharepoint. The gallery is populated based on 4 dropdowns that relate to the columns of the sharepoint. I would like to make the gallery auto populate when the first two dropdowns are filled in rather than all 4 being required to fill in. I would like to still have the other 2 dropdowns required and want the data to autopopulate in the gallery beginning when the first dropdown is selected.

My gallery items code is :

Filter('datasource',
'status'.Value = TextInput1.Text,
'coulmn1'.Value = dopdown1.Selected.Result,

'coulmn2'.Value = dopdown2.Selected.Result,

'coulmn3'.Value = dopdown3.Selected.Result,

'coulmn4'.Value = dopdown.Selected.Result,
)

This basically sets a filter so the only items that populate have a specific status and then it filters based on the dropdown results. All 4 must be filled in, I would like it so after the first one is filled in it would start populating and narrow down as more dropdowns are filled in.

Thank you.

if you want to filter a gallery based on multiple dropdown selections it will take a rather lengthy 'If' statement. you will want something similar to the following *in the Items property of your gallery:
If(
IsBlank('YourComboBoxName1'.Selected.Result) && IsBlank('YourComboBoxName2'.Selected.Result),
'Your SP List Name',
IsBlank('YourComboBoxName2'.Selected.Result) && !IsBlank('YourComboBoxName1'.Selected.Result),
Filter(
'Your SP List Name',
'YourComboBoxName1'.Selected.Result = 'Review Status'.Value
),
IsBlank('YourComboBoxName1'.Selected.Result) && !IsBlank('YourComboBoxName2'.Selected.Result),
Filter(
'Your SP List Name',
'YourComboBoxName2'.Selected.Result = Requestor.DisplayName
),
!IsBlank('YourComboBoxName1'.Selected.Result) && !IsBlank('YourComboBoxName2'.Selected.Result),
Filter(
'Your SP List Name',
'YourComboBoxName2'.Selected.Result = 'SP List Column1'.Value && 'YourComboBoxName1'.Selected.Result= 'SP List Column2'.Value
)
)
this has only been written for 2 dropdowns, but it's the same concept for 4. you just add a couple more 'If' statements to include more dropdowns and it will filter by ALL the dropdowns where a selection has been made. (meaning if only 1 dropdown has a selection, the gallery will filter by the 1 selection that was made. if 2 dropdowns have a selection it will filter by both, etc.)

Hope this helps!

Is there anyway I could add a search button instead of all of these formulas and based on what is filled in it will search? I am struggling with what a few of these formulas mean- I am unsure what the requestor display name is and I am not using combo boxes just dropdowns

@aleisure99 Yes there is, in the items property of your gallery you will want something similar to:
Filter(
[@'Your SP List'],
StartsWith(
'SP Column',
'TextBoxToSearch'.Text
)
)

I mean like a button that would trigger the gallery to filter based on teh dropdowns that are filled in. Not a text input search bar.

There is not, because you would still need the IF statements that tell the gallery when and what items to filter.

Ok,
Attatched is my code for these dropdowns. How can I add more if statements to it? Anytime I add another it gives an error :

If(IsBlank(Cooling_Dropdown_2.Selected.Result) Or IsBlank(Shape_Dropdown_2.Selected.Result),
Filter('SBG Tracker 2',
'Status/ Line #'.Value = TextInput1_1.Text,
'Machine Type'.Value = Machine_Dropdown_2.Selected.Result,
'Equipment Type'.Value = Equipment_Dropdown_2.Selected.Result),
Filter('SBG Tracker 2',
'Status/ Line #'.Value = TextInput1_1.Text,
'Machine Type'.Value = Machine_Dropdown_2.Selected.Result,
'Equipment Type'.Value = Equipment_Dropdown_2.Selected.Result,
'Cooling Method'.Value = Cooling_Dropdown_2.Selected.Result,
'Conical/ Parallel'.Value = Shape_Dropdown_2.Selected.Result
)
)

Sorry i should have mentioned in my previous post that the IF statements will go in the Items property of your gallery, not in your dropdowns.

Can you help me build an if statement? I copy and pasted the one you sent (and edited to my fields) and it did not work. I also tried to build my own but anytime I added a send if statement it failed.

What are the data types of your SharePoint list columns that are being compared?

@aleisure99,
as long as you know the datatypes for your columns you should be able to adjust the following code to fit your needs.
in the items property of your gallery:
//if all dropdowns are blank
If(IsBlank(Dropdown1) && IsBlank(Dropdown2) && IsBlank(Dropdown3), 'YourListName',
//if dropdown 2 & 3 are blank
IsBlank(Dropdown2) && IsBlank(Dropdown3) && !IsBlank(Dropdown1),Filter('YourListName', SPListColumn1.Value = Dropdown1.Selected.Result),
//if dropdown 1 & 3 are blank
IsBlank(Dropdown1) && IsBlank(Dropdown3) && !IsBlank(Dropdown2), Filter('YourListName', SPListColumn2.Value = Dropdown2.Selected.Result),
//if dropdown 1 & 2 are blank
IsBlank(Dropdown1) && IsBlank(Dropdown2) && !IsBlank(Dropdown3),Filter('YourListName', SPListColumn3.Value = Dropdown3.Selected.Result),
//if only dropdown 3 is blank
!IsBlank(Dropdown1) && !IsBlank(Dropdown2) && IsBlank(Dropdown3),Filter('YourListName', SPListColumn1 = Dropdown1.Selected.Result && SPListColumn2.Value = Dropdown2.Selected.Result),
//if only dropdown 2 is blank
!IsBlank(Dropdown1) && !IsBlank(Dropdown3) && IsBlank(Dropdown2),Filter('YourListName', SPListColumn1 = Dropdown1.Selected.Result && SPListColumn3.Value = Dropdown3.Selected.Result),
//if only dropdown 1 is blank
!IsBlank(Dropdown2) && !IsBlank(Dropdown3) && IsBlank(Dropdown1),Filter('YourListName', SPListColumn2.Value = Dropdown2.Selected.Result && SPListColumn3.Value = Dropdown3.Selected.Result),
//if no dropdowns are blank
!IsBlank(Dropdown2) && !IsBlank(Dropdown3) && !IsBlank(Dropdown1),Filter('YourListName', SPListColumn1.Value = Dropdown1.Selected.Result && SPListColumn2.Value = Dropdown2.Selected.Result && SPListColumn3.Value = Dropdown3.Selected.Result))
there is a comment above each line explaining what that line of code is doing. this is only for 3 dropdowns so you will have to adjust for more or less dropdowns.
