PowerApps | Concat not working if fields place in Gallery Control inside data card which is inside the Form

If the Input Fields are place on screen without any form and we concat the fields it works
Set(varStr1,Concat(Gallery1.AllItems,Concatenate(TextInput1.Text,";",TextInput2.Text,"|")))
But same thing if I place them Form --> Data Card --> Gallery-->Input Field Concat does not work
//Set(varStr2,Concat(Gallery2.AllItems,Concatenate(TextInput4.Text,";",TextInput5.Text,"|")))
//UpdateContext({varStr4:Concat(Gallery3_1.AllItems,Concatenate(TextInput5_1.Text,";",TextInput4_1.Text,"|"))});
Set(varStr4,Concat(Gallery3_1.AllItems,Concatenate(TextInput4_1.Text,";",TextInput5_1.Text,"|")))
If you are using a Gallery inside a Form DataCard then position the Button inside the gallery and it will work. Here the onselect property of the button is
Set(varStr1,Concat(Gallery1.AllItems,Concatenate(TextInput1.Text,";",TextInput2.Text,"|")))'.

GroupBy Function NOT displaying Gallery Tiles in PowerApps

This Question is an Extension of my previous question, located here. When I use the Filter code mention in my Question. The Gallery is displaying System Names. However, when I try to wrap my Filter code with Groypby Function as mention by #carlosfigueira, I am NOT getting any Error message. However, I cannot see Gallery Tiles. Gallery is displaying lines as shown in below image. The code I am using under Items Property of my Gallery is below.
Code for GroupBy:
GroupBy(
Filter(Table1, StartsWith('Sys Name',"Sys")),
"Sys_x0020_Name",
"BySys")
Gallery Screen:
GroupBy function returns set of records whereas the text labels expect a Text input due to which you don't see the values in the gallery control.
You can add another gallery (Gallery2) inside the parent gallery's item and bind it to ThisItem.BySys as the data source & set Text property inside Gallery2 as ThisItem.ColumnName1. ColumnName1 would be the column from Table1 collection.

Including an image in a rich text field

I'm using Apex 4.2 and Oracle 11.g.
I have a rich text field that is used to store the body of an apex-generated eMail using SMTP_MAIl. The eMail generation process works fine. But my users want to include an image (jpg, bmp, etc.) into the body of the email, and don't want to include the image as an attachment.
On the Apex page, the rich-text field is defined as a Rich Text Editor / CDK Editor 3 / Toolbar = Full / Toolbar Expanded = Yes / Skin = Office 2003.
The rich-text field writes to a BLOB column.
If I just paste in the image (Shift / Insert) and then go to save the rich text field, I get a 500 - Internal Server Error.
Can you provide some help so that I can include an image in the rich text field? Ultimately, this will be included in the body of an html_email.
Thanks for your help.
The nature of my problem seems to be related to the 32K limit per Apex page item.
A colleague told me to look for a plugin. I found Enkitec's "CLOB LOAD" plugin. https://www.enkitec.com/products/plugins/clob-load
The plugin works well. It's easy to install, and the directions are pretty clear.
I stumbled on a few things to supplement CLOB_LOAD directions.
1) The table item that the Rich Text will write to has to be defined as a CLOB (and not a BLOB).
2) You have to create a Apex Collection using Apex's SQL Workshop. Be sure to include the Begin and End. The directions reference this.
3) If you already setup the form Apex page using the Apex Wizard and the DML page process is there, The "Return Key Into Item" is empty. At least it was with my Apex Page (4.2). That prevented the "Create" button from working. Once I set the "Return Key Into Item" value to the page item that relates to the primary key column of the table, it helped.
4) I also had to copy the page process for the "Save" button suggested by the plugin directions and assign the copied process to the "Create" button. Once I set those two items up, the plugin worked fine for updating as well as creating. It's a good solution.
Using this plugin, I can place a JPG, PNG, GIF, etc. into the Rich Text field, and it will write it to the CLOB, even when the total page item is greater than 32K.

Add an icon instead of a text in a column

in JQGrid 3.8, is it possible to have an icon instead of text in a column ?
I don't think it's possible but if you have a trick, i'd be happy
There are many ways to add icons in the grid. First way is: the data which be placed in the column header (colNames) or inside of the cell data could be HTML data. So you can easy insert the <img> element in the grid. One more method is th use custom formatters. See here some demos. If the standard jQuery UI icons contain all the icons which you need I would recommend you to use there.

Drupal - Use lightbox with Views (Rel attribute) - in output link

In Drupal I have two image fields, one to act as a thumbnail and the other the image that will open when the thumbnail is clicked. The only way I could find to link the two was to use the option for "Output this field as a link" and link to the image field.
This works, so when I click the thumbnail it opens the larger image however I would like to use lightbox2 for this task but in the "Output this field as a link" options there is no way to set the "rel" attribute.
Is there a way to either set the rel attribute or invoke the lightbox by setting a class?
you only need a single cck imagefield to get thumbnail plus full image in lightbox: Lightbox2 - How to use with CCK Imagefield and Imagecache.
UPDATE: use the "Lightbox Trigger" Views field of the Lightbox2 development version. step by step:
add both your thumbnail and your image field to your view
mark both of them "Exclude from display". don't check "Output this field as a link" anywhere.
add a "Lightbox trigger" field after both of your image fields
configure the "Lightbox trigger" field:
for "Trigger field", select your thumbnail field
for "Popup", select the Replacement pattern (scroll further down in the view field edit form for all possible replacement pattern) of your image field. for example, in my case, this is [field_image_fid].
now, your view should show your thumbnail image and, clicking on it, should open your full image in a lightbox frame. at least that's what's happening here :)
