Hello,

We are creating an application where we want to show the Images on the TreeView based in various combinations of conditions.

Depending upon the types of the Nodes we have to attach different context menus to the tree nodes.Here we are using a Class which implements the IPropertyChanged, the properties such as AbstractionType and ObjectType decides what images has to be loaded in the TreeView.

Images are loaded based on various conditions such as the Abstraction Type and the ObjectType.

Copy paste functionality on tree View--- If we select a node say device node in the context menu we will see copy and when paste is clicked the copy of the Node is addedon the same node as that of the node copied.

We are using a class to populate the tree and the Images will get populated based on two properties, say AbstractionType and objectType. Also in some cases we wish to show multiple images in the treeview.

It is quiet urgent ansd any code will be vary helpfull.
Looking forward for your support.

Thanks and regards

Data sometimes not being painted in grid

Several of our grids are behaving like this. They have worked for months and while recently making a change to some of the columns, data no longer appears (column names are visible, and the columns are drawn, but the data inside is missing). If I click on a column to sort, the data appears. So it's like the screen is not initially being painted and an event like column sorting triggers a repaint.

These grids are in a rad tab control and when I click on another tab and then click back, the data disappears as well. The issue might actually be with the tab control.

Any idea what is going on and how to fix?

Delete one or more rows

We would like to use the standard delete key on the keyboard to delete rows from the GridView instead of the adding a delete button to each row in the grid as in the examples provided. This should be fairly easy to accomplish. However, I do not see any events that fire when a cell or row edit begins and ends. This is needed to prevent the keydown event from deleting a row when the delete key is pressed while editing a row. Can you let me know if there are any events that will tell us if the grid is in edit mode?

Thanks,

Doug

UpdateSourceTrigger=PropertyChanged,

Mode=TwoWay}"

CellStyle="{StaticResource GridViewCellDefaultStyle}"

Displaying custom labels when grouping columns

Hello,

We would like to display custom labels in the grouping panel when users drag and drop columns.

Currently, the label displayed is the name of the property.

Is there a way to change it to a custom label ? It would be appreciated to use the HeaderText property of the column grouped.

In our case, we need to display white spaces.

Thanks by advance.

Cheers.
