offline cascading dropdown

Hello,

 

I am looking to implement cascading dropdowns in a form, BUT OFFLINE.

 

it means that my dropdowns to refer to a SP list, or a file. I just hard code the different entry possibilities in the items property of the dropdown.

 

I would like dropdown 2 items to depend on dropdown1 items selected.

 

I tried to do a basic if statement on the items property of dropdown2  but it dosn't work.

 

Does anyone have any idea how to do that.

 

Many thanks in adavance

Hi @blue_lotus,

It sounds like you want your cascading drop down menus to hook up to data offline.

 

Some options:

  • Hard code it with a static Table()--sounds like this is what you're already doing.
  • Connect a static table from Excel: View > Data sources > Import from Excel
  • Collect the options you want locally.

 

If your options do not change or change often, the best option is the second.

 

If the cascading dropdowns would change, then you'll want the third option. Here's an example:

 

// Load any cached data. Suppress any errors.
LoadData(localcollection1, "localcollection1", false);
LoadData(localcollection2, "localcollection2", false);

// If there was not data cached, attempt to do it now. If(IsEmpty(localcollection1), // Collect the items from a SharePoint list. ClearCollect(localCollection1, SharePointList1); // Save the table to the local storage. SaveData("localcollection1", localcollection1) ); // Repeat the same for other tables. If(IsEmpty(localcollection2), ClearCollect(localCollection2, SharePointList2); SaveData("localcollection2", localcollection2) );

 

 

Now that the data is local, you can make localcollection2 dependent on localcollection1 in the Items property of Dropdown2:

 

Filter(localcollection2,column=Dropdown1.Selected.column)

Here Dropdown1 would be tied to localcollection1. Whatever is selected in Dropdown1 would filter Dropdown2 which is connected to localcollection2.

 

There's lots of threads on here for these scenarios. You can do a search for SaveData and LoadData.

Please does this apply to Azure Sql, I am trying to implement it but it not working for me;

LoadData(localCollection1, "localcollection1", false);
If(IsEmpty(localCollection1),
ClearCollect(localCollection1, '[dbo].[tblUser]');


SaveData("localcollection1", localCollection1)
)
