Aspxgridview rowupdating change value dating in japanese language
If you run the example right now and double click on a row, you should see something similar to this: Even if this looks nice and simple, you maybe noticed that the fields are not editable.This is because we didn’t binded our grid to a valid and well defined Data Source.The properties are called logically New Values and Old Values.As Ordered Dictionaries are not so handy for processing, I will create two Hashtables and copy the data for both properties from Ordered Dictionaries to Hashtables.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!In case the user hits Escape key (27) we will just get out of the edit mode by calling Cancel Edit method.
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.
Just call Start Edit Row Java Script method that is defined on the grid (in this case I’m using s and not the Client Instance Name in order to access the grid methods, but here is basically the same) and pass the visible index of the row that we intend to put in edit mode.
Kindly this even will provide us the visible index via the function parameter which will indicate the row that user double clicked.
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 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.
