Hi guys, if enyone is still interested i've found a good workaround for datagrid inline editing.

for tab navigation problem, just don't let the datagrid be the last element of a panel.

bye

Fabio

make sure all cells have cell edit template defined if your datagrid is templated, tab navigation is only available in edit mode. please have a look at this thread

I am getting another bug in inline editing.If the user is editing a cell and press tab to move to next cell the mouse control shifts to browser address bar and the row being edited disappears. Is there any workaround for this issue.

How can i prevent the control being shifted to adress bar on tab press.

Escape enter key all are working fine.

Please help

thanks

That does sound tricky. In WPF I've used Emit to create assembnlies on the fly, and ITypeDescriptor (I think that's right) to present arbitrary type information for my objects on the fly, but I don't know if Silverlight has those capabilities.

Thanks for the info on PreparingCellForEdit. Nice job!

Hi All, I Found a solution for committing edit event.

private void dgRecordTypes_PreparingCellForEdit(object sender, DataGridPreparingCellForEditEventArgs e)

{

e.EditingElement.LostFocus += new RoutedEventHandler(EditingElement_LostFocus);

}

private void EditingElement_LostFocus(object sender, RoutedEventArgs e)

{

var newValue = e.Source as TextBox

}

hope this helps.

thanks

Balu.

Hi xiard, I use a List (Dictionary (string, string)) as the item source of my datagrid. This is because, i need to add new columns in the datagrid at run time. [The angle brackets was not appearing once i posted. Thats why i use the simple brackets instead of angle brackets of "List (Dictionary (string, string))" ].

The modification in grid was not getting updated into the List (Dictionary (string, string)). Thats why i wrote code in the committingedit event of datagrid in silverlight2 beta2 to update Dictionary.

In your example you used class property to bind it with the datagrid column. Can we create properties of a class at run time for this purpose? If so i have to change my whole code.

Is there any way to update the List (Dictionary (string, string)) whenever user do modifications in datagrid ?

Thanks in advance

hi Coderx, I am looking for inline editing of a datagrid. i did it using committing edit event.looking for a substitute for that event.

I feel for you, man. Good luck with it. Too bad you're missing it...it's a good conference so far. Lots of interesting stuff coming out (primarily Azure and C# 4.0 changes, I would say).

xiard:

Why exactly are you trying to hook the LostFocus event?

PS: CoderX, are you at PDC in Los Angeles this week by any chance?

I'm not sure why balukr54 is hooking to the LostFocus event, but I do know that in order to avoid the dreaded disappearing rows bug you do have to set focus in a DataGrid to the DataGrid itself. Maybe that's what he's referring to, maybe not.

Sadly I am not at PDC. The timing was such that I have a ship date next week and thus am strapped to my desk with a Mt. Dew IV and toothpicks propping my eyes open. I will be at Seattle Code Camp next month though if any one wants to get together.

Yes, working with the ComboBox is a pain in the neck, fortunately some good fellows has published work around (some of them are dirty hacks but at least you get it working :-) ).

Yes, about the TextBox, sorry you are right two way binding should be enough.

I use the Load / LostFocus approach to fill up combo's (enumeration is on another itemsource). Not sure if maybe there is a good approach (at the time wrote that code seemed a good one).

By the way some days ago a webcast about datagrid inline editing was published, I have to take a look :-).
