I am trying to select all layers except the background. my ielayermview shows all of them selected. I tried everything. here's my code. if someone has an idea on how to show them all selected but not layer 0, let me know.
var
I: Integer;
begin
for I := 1 to imageenview.LayersCount - 1 do
imageenview.Layers[I].Selected := True;
imageenview.Layers[0].Selected := False;
IELayerMView1.Update;

Hi
Both of these work in my testing:
imageenview1.LayersSelectAll();
IELayerMView1.Update;
for I := 1 to imageenview1.LayersCount - 1 do
imageenview1.Layers[I].Selected := True;
Imageenview1.Layers[0].Selected := False;
IELayerMView1.Update;
Are you sure loAllowMultiSelect is enabled in LayerOptions:

Does not work for me. i have multiselect enabled. look at the screenshot. you can see that the background layer is still highlighted so i assume selected.

Nigel's code works here as expected. After all layers are selected except for the background layer. Both TImageEnView and TImageEnLayerMView show that all layers except for the background layer are selected in both components. Layer 0 is not selected in both components.

What do you have TImageEnLayerMView.LayerOrder set as? I am using TImageEnLayerMView.LayerOrder := ieloBackgroundFirst.
Based on your screen capture it is hard for me to determine if the TImageEnLayerMView Background layer is selected. Your screen capture shows that the background layer in TImageEnView is not selected.

| The background layer is named Ilford.... first one in the bottom of the stack in ielayermview. it is clearly blue and selected. if i look at your screenshot, your background layer is white. |

My screenshot shows the expected results. The background layer is not selected in either component. As I understand it you want all layers selected except layer 0 in both components.
Try my suggestion to see if it works for you.
It is possible that if the background layer is shown at the bottom TImageEnLayerMView may be the problem. I am not sure however.

If i deselect all, the everything looks good. It is when i loop, they get all selected. what was your suggestion ?
How do you make the background layer at the top instead of the bottom ? |

I just tried setting ImageEnLayerMView1.LayerOrder to ieloTopFirst. When I select all layers, all layers are selected in both components except for layer 0. so my idea is not correct. Perhaps you have some other option set incorrectly because here is works.

Ok, i am able to reproduce it. Load the layersediting demo. Create a button with Nigel's code. load an image. then add another image layer. select the background layer in ielayermview. then click the button. both layers will now be selected in ielayermview. see attached.

OK, there is a bug there based on current layer vs. layer selection. We'll have a fix in v8.3.0.
