Rowupdating oldvalues empty
Still there are a couple of tricks that we will see in the following lines.
In order to start editing a certain row, we can choose the way we are going to start this action.
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.
Once Update Edit is called a callback will be generated and the Row Updating server side method will be executed, in which we will need to handle the persistence of the data.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.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 will write down methods that will allow us to update, add and remove the credit card entities.
