Add user controls to Dockpane at runtime

Question

Hi all

I have a user control that gives some options for a layer (include layer name and some  comboboxes depend of the specific layer).

When I press a button to open the Dockpane I would like to insert this user control once for each layer in the map and fill them up.

If I have 3 layers I will insert 3 user controls into the Dockpane and if I have 5 layers - 5 user controls.

No need to get the event of adding layers, I assume the user will press the button if he change the number of layers.

Any code samples?

Thanks

You need to use ObservableCollection for datagrid binding and object of your collection must implement INotifyPropertyChanged. I implement IEditableObject too.

Then you create new item you must to fill StringValues and ComboValue properties too depending on your layer object.

I got this part but the question is how do you do DataGrid.Items.Add in runtime adding different combobox values to each row.

Hi Mody, You need to use different templates in xaml for each combobox column. The xaml source of my previous picture is very difficult . It uses triggers and etc.. I have tried to simplify xaml but I am not really sure about bindings validity. Your binding list object class must have properties StringValues and ComboValue which return some data depending on your layer type. If you need two combox columns then you need to add additional properties StringValues2 and ComboValue2 for next column.Another way is binding to window datacontext:https://gallery.technet.microsoft.com/scriptcenter/WPF-DatagridComboBoxColumn-03c5ea2eBoth ways are a little bit tricky, but you can find more info on internet.
