Dear community,

I have a Textbox for searching in a gallery and a search icon and a cancel icon.

The OnSelect of the cancel icon is set to: Set(searchQuery;"")&& Reset(TextBox1)

Now i need code for clearing the gallery when the user deletes the text in the textbox;

I have tried it myself to empty the variable when the textbox is empty in the OnChange of the textbox. but no luck:

If(
Len(TextBox1.Value) = 0;
searchQuery;""
)

This is the code of the gallery:

If(
Len(searchQuery) > 0;
Search(
dbEmployeeDirectory;
searchQuery;
"crcfa_voornaam"
)
)

Gr. Peter

Hello @PeKi72

How about this:

If( IsBlank(TextBox1.Text); Blank(); Search( dbEmployeeDirectory; TextBox1.Text; "crcfa_voornaam" ) )
