How can I enable / disable RadPanelBar item so that we cannon navigate to it.

Hi,

I have code written by fellow developer who used RadPanelBar to visualize hierarchical datasouce. He wrote (imho too many) templates. Now I am looking how to enable / disable item - I would say functionality like this in TreeViewItem
http://docs.telerik.com/devtools/wpf/controls/radtreeview/features/treeview-item/feautres-treeviewitem-enable-disable-items
I managed to block action in code, nonetheless I am looking how to set it so that it looks nice visually (and I wish to avoid to write xaml code in order just to disable item;))

Best regards,

PanelBar

Usage of telerik:GridViewSelectColumn

Hi

I have added one column as <telerik:GridViewSelectColumn/> so that the user will have the option to select/unselect all the rows at a time. Now I want to access the rows which user has marked as checked on this column.

<telerik:RadGridView SelectionMode="Extended" ItemsSource="{Binding FilterDataGridRows}" SelectedItem="{Binding SelectedData,Mode=TwoWay}"

Doing something like this...but this is not working...

It is suggested on this side to use some dependency property to get the SelectedItems.....

Is there any easy way to achieve the selected rows ??

Custom footer containing the total items count

Hello Telerik,

Our solution needs a footer row for the grids, for now containing only the item count.

I have browsed some of solution for this such as this one, but it won't attend to my needs for a couple of reasons:

- the footer cells need to be merged as if there was a column spam there

- the footer needs to be independent of a column. A simple count of all the rows before and after the grid built-in filtering.

Regarding the second point, please do correct me if I am wrong, but I am assuming that the

<telerik:GridViewDataColumn.AggregateFunctions>

<telerik:CountFunction Caption="Count: " />

</telerik:GridViewDataColumn.AggregateFunctions>

is out of question, since it is column-bound. And the reason why it won't serve is because my grid has a columnchooser. if the user unselect that column, the count will disappear. Which is pointless. So I didn't even bother looking too deep on how to merge cells horizontally, since I believe a row just below the grid containing the count should be the way to go.

Furthermore my grid receives a VirtualQueryableCollectionView as datasource. And the only indicator of the Rows Count that it has is the VirtualItemCount = data.Count(). The problem is that property won't change in case the user filters the grid.

Finally my question is: where can I find the Grid Total Rows Count that will also show the right number after filtering?

Thank you

Showing inserted row

hi

I have an EntityFramework table as my ItemsSource:

Ent = new Data.xEntities();
RadViewGrid.ItemsSource = Ent.Table;

If I insert a row from the "new row" row in the grid it disappears an does not show in the grid. Even if I Rebind() the grid.

If I

Ent.SaveChanges();
RgvUsers.Rebind();

it works. But I would like to save all changes at once via a Save Button.

How can I make the inserted row show in the grid without committing it back to the db? Thanks.

Regards,
Michael
