Winui3: How to insert in the middle of GRID in C++/WinRT?

Harshithraj1871 1,706

Hi,

I have a 5x5 GRID. Each element in the grid are textboxes, I want to insert a row of textboxes in the center of the grid in the runtime[Say I want to insert rows when the user double clicks on the row]. It would be of great help if you could help me in achieving this behavior.

I tried ,

Grid.Children().InsertAt(INDEX, Control);

But this didn't work, it was inserted at the beginning of the Grid[at position [0,0]] overlapping the existing control.

The Grid layout does not automatically change the position, you need to design your own algorithm.
For example, when (2, 2) needs to be inserted, the positions of all controls in the grid are obtained through GetColumn and GetRow methods. If it is after (2, 1) , it needs to move backwards.

Hello @Harshithraj1871
Welcome to Microsoft Q&A!

You can use Grid.SetRow and Grid.SetColumn to set the position of the new control.

    Grid().SetRow(Control,INDEX);  
    Grid().SetColumn(Control, INDEX);

Thank you.

Hi @Junjie Zhu - MSFT , Thank you for your response.

I tried that, but it was inserted at that position overlapping the previously existing cell element. It did not push the element existing at that index to next index.
It came something like this[In row-1, column-0]

How to insert it in the middle of the grid so that the existing element at that index will move to the next index?
