@azizqureshi1 - I think you have missed some key information in your description. Could you provide more detail on what you mean by "container". Also, please share screenshot of your app if possible.

@azizqureshi1 there are controls in Canvas Apps called "Containers", I suspect those are not what you mean.

Despite the screenshot, I still do not understand what you mean by "container that has the controls on the screen."

@azizqureshi1 I am struggling to understand your app with the information you have provided. 

Remember, I do not know your app, I do not know what it looks like, I do not know what "OverViewMandatoryCount" is, I do not know why you have two Galleries in there inside a container, I do not know why you're using multiple containers etc etc

Provide detail

[azizqureshi1]

Let me explain. I have a simple screen. The screen looks like the following:

The button 'Create Collection" has the following code:

ClearCollect (
col_Test,
         {
            Title: "Title 1",
            Index: 1,
            Number: 0
        },
        {
           Title: "Title 2",
           Index: 2,
           Number: 0
       },
      {
          Title: "Title 3",
          Index: 3,
          Number: 0
      }
)

The gallery Items property has the collection col_Test.

The 'Update If' button has the following code:

UpdateIf(
col_Test,
     Index = 1,
    {Number: Rand()}
);
UpdateIf(
col_Test,
    Index = 2,
    {Number: Rand()}
);
UpdateIf(
col_Test,
    Index = 3,
    {Number: Rand()}
)

Now this is the issue. I have clicked on the second item in the gallery:

Now if I click the 'Update If' button. The Number field in the items gets updated, but the gallery selected item becomes the first item without me clicking the first item as shown below:

I want the gallery's selected item to remain the second item and not change to the first item when I click 'Update If' button. Please help, I am desperate.

I have come up with a solution.

On the Select property of the button 'Create Collection' create a copy of the collection col_Test, by ClearCollect(colNewCollecion,col_Test) at the end of the code.

On the Select property of the button 'Update If' create a copy of the collection col_Test, by ClearCollect(colNewCollecion,col_Test) at the end of the code.

The Items property of the gallery will be colNewCollecion.

Now when the col_Test is updated a copy is made in the colNewCollecion. Since the Items property of the gallery is colNewCollecion. The changes are shown in the gallery. With out the items changing in the gallery.

@azizqureshi1 - as salaam mu alikom. Sorry I did not receive the usual notification that you had responded.

Thanks for the description, it is a lot clearer.

Why not set the Default property your Gallery to:

LookUp(
    col_Test,
    Index = 2
)

Or:

Index(
    col_Test,
    2
)
