It may be set to one of the following values: In R2 2016, Telerik introduced the Validation Type property of Rad Grid View. This results in a binding validation error (Figure 3) and the Grid View Bound Column Base editor will enter into an invalid state.It provides you with the possibility to choose what type of validation to apply for each instance of Rad Grid View. In the previous examples, the data was validated per cell, using the Cell Validating event or property validation.i cant, the user HAS to modify it, it's a criteria i was given and not my choice.
Rad Grid View exposes a property - Validates On Data Errors - that controls the way the data validation, provided by IData Error Info and INotify Data Error Info Interfaces, is performed. Length When you try to enter an order number that has fewer than five characters, you should see a validation message that is similar to the one in Figure 2. Is Valid property to False, this will cancel the editing process and will return focus to the invalid Grid View Cell. In this case, you need to throw an exception when an incorrect value is about to be set.
i want the row to be blocked until the user provides appropiate input to my primary key, the column is called "LOOPS" on index 5, however with the code i've posted it only triggers the lockdown if i step on the primary key!
just make sure the PK column is in read only and also, eventually, hidden so no user will edit it.
By default, if the value of a cell does not pass the validation process, the cell will exit edit mode and the value of the cell will be returned to its original valid value.
Custom validation can be provided at either the row or the cell level depending on the kind of validation you want to provide.
As of version 2.2 of the grid, it is possible to provide custom error behaviors for both cells and rows (Cell Row) when the value of a cell does not pass the validation process.
