Sort order items of an itemtype by date (created_on property)

Hello,

You can configure this directly from the ItemType without needing to write any code by following the steps below.

1. Login as admin
2. Navigate to the desired ItemType
3. Click the Edit button
4. Go to the Properties relationship tab
5. Scroll down to created_on and enter '1' in the Order By column
6. Check the other properties to ensure there is no other Order By set
   1. If there is, either remove it or make sure it is a number greater than '1'
7. Save and close your ItemType

When the results of a query are returned for an ItemType, it checks to see if any properties have an Order By set. If there is just one property, the results of the query are sorted by that property. If there is more than one property, the results are first sorted by the property with the lowest value and then by the property with the next lowest value and so on.

Hello Chris,

Thank you for your reply,

This is what i have done, the results of the query are sorted by that property (created_on) but in ascending order and not

descending.

Do you have an idea on how to get the results in DESC order ?

Hi mouad,

Thank you for clarifying. Your assumption was correct originally then, it is not currently possible to configure whether the sort should happen in ascending or descending order purely through the ItemType.

You can do this programmatically through an onBeforeGet event though. The code is pretty simple and can be seen below.

this.setAttribute("orderBy","created_on desc");
return this;

There's no need to even do an apply since that will happen automatically as part of the standard Get functionality of Aras Innovator.

Thanks Chris, this is very Helpful

Thanks for this info.  It worked for me as well.

Hi Cris,
this approach is extremly critical!
The problem is that all AML querys in the methods with a different sortOrder return a wrong result.
Because the OnAfterGet is overruling the sort order in the AML query.

Any other approach to sort descending in the searchgrid?

The solution is perfect, when using a "onBeforeGet" Method! This way the AML result is sorted before being displayed in the grid.

This is working well in the searchgrid.
But we had a lot of issues after setting the sort order in the OnBeforeGet server event and many actions and programs where not working properly after that.

example:
Method in the Part ItemType OnBeforeGet
Set the item_number sort order to descending

this.setAttribute("orderBy","item_number desc");
return this;

Run an AML with a different sort order:
In this example want the item_number sorted not descending but ascending
<Item type="Part"  action="get" select="item_number,name" orderBy="item_number asc">
  <name>Extruderhalter</name>
</Item>

Result: sort order is descending!
The OnBeforeGet event has overruled the sort order!

This is extremely critical because there are a lot of (custom) AML querys with different sortOrder in the methods code and the result is unexpected!
To get the expected result a serverEvents="0" Attribute is neccessary in the AML query.
But that would mean that all methods with AML queries and sortOrder have to be investigated and changed.

Ah ok! Now I understand your problem and I confirm this behavior. Indeed, the custom AML can be overruled.

Maybe you can check in your Method if certain attributes are present that are typically used for the search grid. Typically the "page" attribute, but there are also others like pagesize or return mode:

string page = this.getAttribute("page","");
if (page == "")
{
   return this;
}

this.setAttribute("orderBy","...");

Edit: Maybe an even better variant! Check if an orderBy attribute is passed already and skip the Method if this is the case.

string orderBy = this.getAttribute("orderBy","");
if (orderBy != "")
{
   return this;
}

this.setAttribute("orderBy","...");

I haven´t tested any of this variants, but I like the second idea very much! Please let me know if any of them work! I think I will implemented them too.

Best regards!

Hi Angela,
the second idea looks good.
I tested this and it works perfectly now.

if (this.getAttribute("orderBy","") == "")
    this.setAttribute("orderBy","item_number desc");
return this;


Thank you for this great approach,
Ronald
