How to keep check box status on Grid after page change?

[Daochuen]

Hello,

Does anyone have an idea how to keep check box check status when changed page? 

I added check box as a ( ClientTemplate) column, user can check or uncheck them. but check box's value was removed after page moving. How to keep those status?  Thanks in advance.

Hi Zhihong,

Generally speaking if the checkbox is connected to a Property in your model, it should not be editable unless you are in edit mode. You can use the ClientTemplate to visually display a checkbox instead of true/false in your column, but in order to change the value(check/uncheck) you should edit the underlying data itself. Your client template could be something similar to this:

columns.Bound(p => p.BooleanProperty)
                    .ClientTemplate("<input type='checkbox' #= BooleanProperty ? 'checked= checked' : '' # disabled='disabled' ></input>");

And the update method in the controller:

public ActionResult Update([DataSourceRequest] DataSourceRequest request, MyModel model)
		{
			return Json(new[] { model }.ToDataSourceResult(request));
		}

If you are trying to do checkbox row selection, please have a look at the following demo.

Let me know if you have any questions.
