Hello,

I am trying to access events for checkboxes in a column in the Grid object. I need to be able to enable/disable other interface elements (e.g., buttons) based on the state of the checkboxes on the client-side, updating as the changes happen.
The ItemChanged event would appear to be what I am looking for here, except that it does not occur after each change. Is there another event I can use or any way to get ItemChanged to fire on a per-change basis on the client-side?

Thanks,
Brett Grimes

Hi,

Unfortunately we are not aware of an easy way to do that now. We have a new build that should come out soon and it supports ClientSideBeforeEditItem and ClientSideAfterEditItem. We will see if that can cover the situation.

Thanks

Yes, there is a way how to do it. Instead checkbox column create a custom column:

<eo:CustomColumn Width="30" ClientSideGetText="on_column_gettext">
<CellStyle CssText="MARGIN: 0px; PADDING-LEFT: 2px;" />
</eo:CustomColumn>

and write javascript functions:

function on_column_gettext(column, item, cellValue)
{
return "<input type=\"checkbox\" id=\"checkbox" + item.getIndex() + "\" onclick=\"check_rows(" + item.getIndex() + ")\"/>";
}

function check_rows(rowIndex)
{
alert("Three things are certain: Death, taxes, and lost data. Guess which has occurred.");
}

Try it!

Thanks for sharing!

If you wish to raises server side event, you can replace alert with:

Code: JavaScript 
eo_GetObject("Grid1").raiseItemCommandEvent(rowIndex, "anything");


This will cause server side ItemCommand event.

Thanks
