Hi,

I want to validate input field inside a repeating table. User should not be able to create a new line if the first some fields in the first line of item is blank and the save button should be disabled if any of the input field contains no value.

Hi @codeworks ,
I'm assuming you are using gallery control here to edit grid.
So, if you want to disable the Save button for selected item add the following code on DisplayMode property of Save icon

If( ThisItem.IsSelected&&(IsBlank(TextInput2)||IsBlank(TextInput3)), DisplayMode.Disabled,DisplayMode.Edit)

In case you are not using any gallery, you can add validation to Save button like following

If(IsBlank(TextInput2)||IsBlank(TextInput3), DisplayMode.Disabled,DisplayMode.Edit)

else option could be if you want to make button editable, notify user a message if validation doesn't meet by adding following code on onSelect property of button

If(IsBlank(TextInput2)||IsBlank(TextInput3), Notify("Please fill required fields",NotificationType.Error),Patch(Datasource,Defaults(Datasource),{key:value}))

Hope this helps,

Cool!!!. All your approaches works.. But what I observed is, once a new line item is added, the save button of the new line item will be enabled even with text input not having values.

Then you also make sure to Reset the input controls you are using on Save button and on onVisible of screen
Reset(Textinput)
