Validation

Question

Hi I have a WPF application and I'm using using a dataset to perform CRUD operations. I'm also using a ValidationRule for all the textboxes. What I want is that if the user clicks the ADD or UPDATE button I want to check if the window validates and if so then I want to Insert or Update data.

Hi Banketeshvar Sorry for coming back you late. Thank you for taking time to answer my question. The articles you suggest helped but it's not enough for what I want to achieve. What I want is to check if the Window validates like on WinForm: if(this.Validate()){ dataset.tableFoo.AddNewRow(x) } Alternatively I want a command to disable the ADD and UPDATE buttons if the a validation fails. I will really appreciate it if you can help. Thank You.
