I want to us an Image through is a text box where in user clicks on the image he should be able to see the current slection.
is this possible please help.
Yes, it is possible through the variables.
Go to Text box properties->actions->create a variable.
And create a Current selection box go to properties->Layout->Conditional pass this var.
Then if you click on the image you can view the current selection and uncheck it will be hidden.
You didn't say where you want the selections to be displayed so I assume a current selections box will do. You can just set an action in the Text object properties that sets a variable value. That variable can be used to conditionally show or hide the current selections box.
If you want the selections to show in the text box itself then create the variable but instead of using a current selections box just put an IF statement in the Text of the text box. Something like this: if(VTest = 'True', GetCurrentSelections(', '))
