Hello,
I'm trying to show and hide groups and single items of a PropertyGrid depending on the answers inside the same propertyGrid.
I've seen that a good place to set the visibility of the group is in when the grid is created, in this function:
private
void
RadPropertyGridOnCreateItemElement(
object
sender, CreatePropertyGridItemElementEventArgs e)
{
if
(e.Item
is
PropertyGridGroupItem groupItem)
{
var myItem = (MyItem)groupItem.Group.GroupItem.GridItems[0].Value;
groupItem.Visible = myItem.EnableGroup;
}
if
(e.Item
is
PropertyGridItem item)
{
var myItem = (MyItem)item.Value;
item.Visible = myItem.EnableItem;
}
}
However, I'm not able to change the visibility at a second time, since this function is not called again later.
If I try to change the visibility of the VisualItem in OnItemFormatting, the items are hidden, but the spaces are not recalculated and the design is messed up.
Also, if I try to change the visibility of an item at the end of OnEdited, OnItemFormatting goes on loop.
Any hint? :)
Thanks!
Hello,
I use a RadGalleryElement in my ribbonbar. I found that after I expanded gallery and then re-collapsed, the collapsed gallery size will be changed automatically. Please see the first attached photo. How can I keep the size of gallery unchanged (original one or the smaller one) ?
FYI,
My gallery is autosize = true, the items are added dynamically at the form loading.
I've tried autosize=false, the gallery is completely disappeared. Weird.
Second question, how can I display selected item effect as the second attached photo ? I found few theme can support selected item effect, like windows 7 theme. But I use windows 8 theme.
How can I show selected item effect in program ? If not possible, please tell me which property I can modify in theme.
Thank you.

Hi there,
I'm using a RadGridView with a DateTime column. The property for this column is a nullable DateTime property. I read on a few forum posts that I need to add a FilterDescriptor for the nullable DateTime columns manually. So I added the descriptors the following way:
FilterDescriptor desc =
new
FilterDescriptor();
desc.Operator = FilterOperator.IsEqualTo;
desc.Value =
null
;
desc.IsFilterEditor =
true
;
col.FilteringMode = GridViewTimeFilteringMode.Date;
gv.Columns[
"WishDate"
].FilterDescriptor = desc;
When the data binding is complete, it instantly filters for null value in this column. But I don't want to filter right away. When I don't add the FilterDescriptor, the default FilterOperator for this column is "None".
What I need on startup is this nullable DateTime column with "Equal To" filter and not already filtered data.
I hope you know what I mean :)
Regards,
Danilo
