Hi Tayyaba,

I understand that you want to display the number of selected line in the listbox on a button.

Each entry in the listbox has an index. Index of the current selection of the listbox can be obtained by using the “ValueIndex” property of the listbox object. This index can be used as the “line number”.

You can use the “ValueChangedFcn” callback which is triggered whenever the current selection in listbox is changed. In this callback, change the text on the button.

You can refer to the following code:

function listBoxValueChanged(event, button)
idx = event.ValueIndex;
button.Text = ['Line ' num2str(idx)];
end

fig = uifigure;
lb = uilistbox(fig,"Items",["Red","Green","Blue"]);
b = uibutton(fig);
lb.ValueChangedFcn = @(~,event) listBoxValueChanged(event, b);
