Facility Control

Hi all, 

Just starting to get into Dashboard and was wondering if there's any way to open up a load or save dialog, or even a folder picker?

I found the sample .grids from Ben Gatien that included 

• Reading and Writing Files or Directories: How to read different file formats and how to write back to files.

but you have to manually type the folder name into a text box.  I also found ogscript.upload() that opens a file dialog box so I know the functionality is technically possible, but I can't find a more general solution.

Thanks,

Hello Rich,

sorry for the delay.  Can you expand on the use-case you are trying to execute?  What 'data' do you want to load from/save to file?

Regards,

Hello Rich,

Using the file picker opens very fast on my computer.  I would suggest trying on a different computer.

You can create a task on the file picker parameter which will get invoked once the user closes the picker.  I recommend using the Visual Logic editor to create your task.  Here is a simple example of a panel which has a picker and text field to display the first line of the selected file.

<abs contexttype="opengear" id="_top" keepalive="false" style="">
   <meta>
      <params>
         <param access="1" maxlength="0" name="selectedFile" oid="selectedFile" type="STRING" value="" widget="file-picker"/>
         <param access="1" maxlength="0" name="firstLine" oid="firstLine" type="STRING" value="" widget="default"/>
      </params>
   </meta>
   <param expand="true" height="36" left="21" oid="selectedFile" showlabel="false" top="20" width="408">
      <task tasktype="ogscript">/*! block id=1006,1003,1002,1000 !*/
params.setValue('firstLine', 0, ogscript.createFileInput(params.getValue('selectedFile', 0)).readLine());
/*!!
 &lt;block id="1006" type="param__top&amp;amp;firstLine (firstLine)[0]" x="837" y="116" w="243" SET="ID:1003" /&gt;
&lt;block id="1003" type="file_readLine" x="566" y="118" w="243" FILEID="ID:1002" /&gt;
&lt;block id="1002" type="ogscript_openfileread" x="342" y="118" w="243" PATH="ID:1000" /&gt;
&lt;block id="1000" type="param__top&amp;amp;selectedFile (selectedFile)[0]" x="104" y="115" w="243" SET="" /&gt;
!!*/
/*!!&lt;checksum&gt;6363f78e8f281b78e70034f5af98d847&lt;/checksum&gt;!!*/</task>
   </param>
   <param expand="true" height="46" left="23" oid="firstLine" top="64" width="1200"/>
</abs>

Hope this helps,
