Rowupdating e oldvalues
I need an old value of field "Picture Big" in Row Updating handler like this: e.Old Values["Picture Big"] To achieve this I use bound unvisible literal in edit item template...
Kindly this even will provide us the visible index via the function parameter which will indicate the row that user double clicked.The main goal for this time is to add inline editing functionality to the grid, in order to be able to update the imports and manage adding, editing and removing credit cards.However we will add also a couple more enhancements in order to show the potential of the grid and offer benefits to the end users.No more code is necessary for managing data and we can now comfortably start with the interface. There are several methods for achieving the same result.If you are interested in more you can check this Grid Editing – Edit Modes A rich set of editors for different column types allows column values to be modified with ease.We will write down methods that will allow us to update, add and remove the credit card entities.
public static bool Add New Credit Card(string credit Card Name) public static bool Update Credit Card(int credit Card Id, string credit Card Name) public static string Get Credit Card(int credit Card Id) public static bool Remove Credit Card(int credit Card Id) This code is pretty straight forward.
I will not waste space in this post so I will show you only what you would need to add.
public static bool Remove Import(int credit Card Id, int year, byte month) public static bool Add Import(int credit Card Id, int year, byte month, decimal import) public static bool Update Import(int credit Card Id, int year, byte month, decimal import) This is it.
As first, we are indicating the cell as read only, after that we are casing the control to an ASPx Text Box (which is the right control for these columns) and setting several parameters in order to make the editing look proper.
The most important thing is that we are assigning to each of editing cells a client side event Key Down, in which we will manage the persistence. If Enter (13) key is pressed meanwhile we are in one of editing cells, we will prevent the defaults for this action and call Update Edit method on our grid.
The database is part of the project and it will be automatically mounted by VS.
