Hi,
Does anyone know how to achieve this?
Use a page property which is set to the Value of the TextBox. Then set the Disabled property to ${textBoxValue.length == 0}
.
Hi @korchev,
That work for me. Thank you.
Just wondering how could I make multiple conditions in DISABLE property.
I try to set it as
but both way hit the error.
Change to
${textbox1.length ==0 || textbox2.length ==0}
What is textbox1? If it is the TextBox itself it won't work - you need a string page property.
Hi @Vinod_Pillai,
Thanks and it works for me.
It just a textbox with string type, and this ${textbox1.length ==0 || textbox2.length ==0} works for me.
thanks
Is this still a valid solution? I am trying this in my Blazor app and it doesn't like the syntax. $ unrecognized character.
This thread is for Angular and the solution applies only to Radzen Angular applications.
Sorry, just noticed this is in the Angular section. Is there a way to do this in Blazor?
Ah, I have found my answer: Disabled="@(string.IsNullOrWhiteSpace(SelectedUserName))"
Thanks anyway.
