I want to display a message when no data on table, something like below but it’s not working, plz let me know how to mention for table if nodata
if (LotId!="" or MatlAutoId!=None) and vtable==dataset[0x6]:
self.props.emptyMessage.noData.text="No Data Found"
self.props.emptyMessage.noData.icon.path=material/sentiment_very_dissatisfied
else:
pass
You cannot do this. If vtable is a dataset, you could do vtable.rowCount == 0

You’ve posted the same question in multiple topics. Don’t do this. And this one dates back to well before Perspective existed. ):

This should probably be in its own topic as it doesn’t really fit the OP, if an admin can split it for us. ![:slight_smile: :slight_smile:](https://emoji.discourse-cdn.com/twitter/slight_smile.png?v=10)
Why does it need to be scripted, instead of just setting those two properties and be done?
EDIT: nvm, I just saw the new thread. I’ll continue over there.

By using noData prop, i can display the msg and icon as below: lot no. and matl name not entered here but the message still shows but it shouldn’t b
but I want to display the message only when lot no. or matl name is entered coz table data displays based on lot no./matl name so where I can trigger to perform that function ?
I would make a few custom properties on the table and bind with expressions.
-
an array with the different noData values you want. The attached examples has an extra one to remind the user to enter Lot and material. I copied and pasted it from the props section. ![:wink: :wink:](https://emoji.discourse-cdn.com/twitter/wink.png?v=10)
-
a value of the data row count
len({this.props.data})
-
an index to pick which noData value you want to use (In my example I also added custom properties for lot and material, but you can bind those to where you enter them.
if({this.custom.MatlAutoId} = '' || {this.custom.LotId} = '',
2,
if({this.custom.rowCount} = 0, 1,
0
)
)
Then you can bind props.emptyMessage.noData to your custom message
property('this.custom.noDataMessages[' + {this.custom.noDataIndex} + '].noData')
