How to speed up DataGrid or can I implement my image grid in ListViews RRS feed

  • Вопрос

  • greetings!

    I created a simple program, for inserting the selected pictures into cells, for the implementation of the grid with cells, I chose DataGrid, it was difficult enough, this is my first application. but in the end a surprise was waiting for me, the DataGrid turned out to be difficult to scale when the cells are 100x100, the grid is drawn for 5 seconds, it’s not so important, the important thing is that when I click on the cell the value changes

    <Image Source="{Binding}"/>

    so that I immediately see a change I have to do

    MyDataGrid.Items.Refresh();

    Which causes a delay of 5 seconds if the cells are 100x100.
    Question:
    How can I speed up updating a DataGrid or can I bypass DataGrid.Items.Refresh?

    I tried to implement a grid on a ListView but I could not create a dynamic grid.

    I don’t care what class draw the grid.

  • Hi Devoleksiy,

    Thank you for posting here.

    According to your description, your issue is more related to WPF. Therefore, it will be more appropriate to ask your question in WPF forum.

    The CLR Forum discuss and ask questions about .NET Framework Base Classes (BCL) such as Collections, I/O, Regigistry, Globalization, Reflection. Also discuss all the other Microsoft libraries that are built on or extend the .NET Framework.

    Thank you for your understanding.

    Best Regards,
