Asked On February 16, 2007 11:19 AM

A college has configured the EditControl to provide a drop down list of options (See attached diagram) Unfortunately this person no longer works for the company and I have been unable to understand how this functionality has been implemented.

1) Please can you point me to some samples or documentation?

2) '[' is used to trigger dropdown, but this only appears to work once. Our users want to be able to select multiple items from the list, seperated by ','. Please can you tell me how I can implement this?

Thanks

Hi Jay,

1. In EditControl the ContextChoice support allows you to create popups for displaying a list of options. The context choice displaying characters are specified in the configuration file using the DropContextChoiceList attribute in the lexem for the corresponding character. If you wish to display the ContextChoice dropdown in response to period (".") or comma (",") being typed, use XML code as shown below:

lexem BeginBlock="." Type="Operator" DropContextChoiceList="true"
lexem BeginBlock="," Type="Operator" DropContextChoiceList="true"

I have attached a sample that illustrates this.

Documentation on ContextChoice can be found at the link given below

2. It is possible to trigger dropdown using the '[' and ',' using the DropContextChoiceList attribute. I have attached a sample that illustrates this.

Thanks exactly what I was looking for. However, is it possible to do it all in code? I'd rather not have to use an xml file to configure the behaviour.

Regards

Hi Jay,

It is possible to configure the behavior in code without using an xml file using the ISnippetFormat and ConfigLexem class. I have attached a sample that illustrates this. Please let me know if this meets your requirements.

Thank you for your patience.

Hi Jay,

Our apologies for the delayed response. I have tested for this issue using v4.4.0.51 and was not able to see the problem. This is how I went about testing this issue :

1. Run the attached sample.

2. Type '['

3. ContextChoice is displayed.

4. Select an item from the ContextChoice.

5. Press Ctrl+A or use the mouse to highlight text.

6. Text is highlighted.

Please let me know if I am missing something. Also, Could you please let me know the version of Essential Studio being used by you.

Thanks for your patience.

Regards,
Ebenezer.P

Sorry, I must not have been clear. My problem is when any text is added in the control. Left clicking and dragging the mouse does not highlight/select text, neither does Ctrl-A.

Standard text highlighting/selection is not working.

Thanks in advance.

I am using version 3.301.0.50.

Ctrl-A moves cursor to the end of the text but doesn't highlight the text.

Any ideas?
