How do I let the user jump to the next fitting item after pressing a key in an WPF Data grid?-CodePudding

This is the WPF-Datagrid I use:

<DataGrid Grid.Row="1" x:Name="products" CanUserAddRows="true" MouseDoubleClick="products_MouseDoubleClick" InitializingNewItem="products_InitializingNewItem" IsReadOnly="True"/>

The products-Dataset has a Property called "Nickname" and is sorted by this property. When the user presses a letter (for example "m") I want my datagrid to select the next Row with a nickname starting with "m".

In short: I want my dataGrid show the standard behavior like most datagrids in Windows (e.g. explorer).

This code:

private void products_KeyUp(object sender, KeyEventArgs e)
{
    foreach (ProductDatasource item in products.Items)
    {
        if (item.Nickname.StartsWith(e.Key.ToString()))
        {
            Debug.Print("Found it, but how to set the selection?");
        }
    } 
}

will find the first Item which starts with the letter. But how can I select this item?

And as pretty every Grid in windows shows the same behavior (even in a more complicated way like starting the search from the current position; if you press 2 keys shortly after another like "mi" it searches for the next item starting with "mi") I wonder if the DataGrid has built in behavior I can use to do this?

CodePudding user response：

Set the SelectedItem property of the DataGrid:

private void products_KeyUp(object sender, KeyEventArgs e)
{
    foreach (ProductDatasource item in products.Items)
    {
        if (item.Nickname.StartsWith(e.Key.ToString()))
        {
            products.SelectedItem = item;
        }
    }
}
