GridView GridViewCheckBoxColumn to NOT persist from edit mode

[Alex]

Hello,

I have a GridView which is readonly and a GridViewCheckBoxColumn which is not readonly and the checkbox can be ticked and unticked. However when I tick and untick and update the bound property, the value gets persisted to the data store which I imagine is default behaviour if the cell value (i.e. true or false for a checkbox) is valid. This is no good in my scenario. I need to be able to edit this checkbox and update the bound property but NOT persist to the data store; I will do this later in the code myself. How is this achievable please?

I used the MainGrid_CellValidating event and set IsValid to false but this shows up the red border around the cell which I do not need.

Please help.

Thanks,

Alex

Hello Alex,

 As I understand you have a property bound to the GridViewCheckBoxColumn. You would like to have the bound property updated, but not saved to your data store.

If this is the case, then I would suggest you to define a collection to be used for working with the GridView. Then when you are done with all the changes, you could save them to your data store.

Hello,

I have the ItemSource of the GridView as a collection already and when I check the checkbox the value true is persisted to the data store automatically which I do not want. Is there not a property on the GridView or GridViewCheckBoxColumn which turns off this behaviour?

Thanks,

Alex

Hello,

 I am afraid that the CheckBoxColumn could not do that.
