DEVELOPERS FORUM - How to display a different relationship tab depending on some condition when opening a form

RemcoVanOosterhout - Monday, June 8, 2015 7:25 AM:

I'm working on the following:

Depending on one condition or another, I want to be able to show, say, the third relationship tab of a form rather than the tab with index 0 (or the lowest sort order) when opening a document form client side.

So far I've been able to recover the ID of the tab currently (and defaultly) shown, yet I haven't been able to display the third tab rather than the first. I haven't been able to find a method to display a tab with a certain index/ID/name/whatever. What am I overlooking?

Hi Remco,

please have a look at www.aras.comhttp:/.../867.aspx

I didn't succeed to use SetTabVisible while SetTabEnabled works great.

I suspect a "bug" somewhere in SetTabVisible.

Hope it helps and please keep the community posted about you findings.

Dear Jeroen,

The problem doesn't have to do with visibility or enabling a tab. Toggling the visibility of a tab only affects whether the tab is visible on the form or not, not whether the tab is displayed at any given point in time or not. I do not want to hide any tabs for my users, I just want to show them a specific tab (which may vary depending on a set of conditions) whenever they open the form.

Edit: I solved the problem this morning, using bits from the standard Aras "ItemType Form onload" method. Below is the result:

//Method: cof_Document_ShowStarterTab
//Fired on: onAfterPopulate
//Author: Remco van Oosterhout, Cofely Energy & Infra
//This: Document
//Method ensures that the user is shown a specific tab when opening a document form
//The tab shown depends on the current state of the document

top.system_ItemTypeHideTabs = function ()
{
     // Used as onload event for ItemType Form.
    // Make sure there is a relationships frame
      if (!parent.relationships)
      {
        setTimeout("top.system_ItemTypeHideTabs();", 100);
        return;
      }
 
      // If the document isn't ready, wait a bit and try again
    if (parent.relationships.document.readyState != "complete" || !parent.relationships.currTabID){
        setTimeout("top.system_ItemTypeHideTabs();", 100);
    }
      else{
       
        var thisState = this.item.getElementsByTagName("state");
        var thisStateString = thisState[0].text;
       
        var tabIds = parent.relationships.relTabbar.getTabOrder('|');
        var a = tabIds.split('|');
       
        //Select the index of the desired tab
        if (thisStateString === "Released"){
            index = 3;
        }
        else{
            index = 1;
        }
       
        // Show the desired tab
        parent.relationships.relTabbar.selectTab(a[index]);
  }
};

// Wait a bit before starting
setTimeout("top.system_ItemTypeHideTabs()", 200);
