Aspxgridview rowupdating newvalues
Because of this, we have our edit controls in read only state.
You can find on Devexpress support web site several issues that are speaking about this behavior and why of it. Define the following server side event: What we defined here is checking if the cells that are going in edit mode are the one we are aiming to put in edit (not the Name and Total columns) and if so we are setting a couple of properties.
We need to attach the following method to the Row Updating event: What happens in this event is that a request for updating rows is sent.
We will receive the old values that (of interested updating columns) and the new one that were chosen by the user, in a form of Ordered Dictionaries, exposed by two properties in our event argument.
Still I will let you discover them and invent new ones.
We are going to make our row editable on double click and in order to achieve that we will write down a function (in Java Script) that is going to be associated to the grids client side event called Row Dbl Click. At first we will add in our ASPX file, inside the grid definition a new section that is called Client Side Events (as we already did for other controls) and it will look like: It is that simple!
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.Last but not least you will need the 12.2.5 version of Dev Express ASP. If you do have a more recent version, upgrading the project should be easy.Check this post about how to get the Dev Express controls and on how to eventually upgrade the project 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.
