向 DataGrid 中的某些行添加效果

发布于 2024-10-01 09:10:00 字数 503 浏览 6 评论 0原文

这就是我想要的： 当用户单击按钮时，满足条件的所有行都应添加模糊效果

问题：我发现执行此操作的唯一方法是在 LoadingRow 事件中。但就我而言，当我想应用模糊效果时，该行已经加载。

问题：如何迭代行以便我可以应用模糊效果。或者，更好的是，如何将效果绑定到行？

这是我的代码，仅在启动时应用效果时才有效：

    private void dg_LoadingRow(object sender, DataGridRowEventArgs e)
    {
        if (true) // Logic for figuring out if a row should be blur'ed
            e.Row.Effect = new BlurEffect { Radius = 8 };
    }

帮助

This is what I want:
When user clicks a button, all rows that meets a criteria should have a Blur effect added

Problem: The only way I've found to do this is in the LoadingRow event. But in my case the row is already loaded when I want to apply the Blur Effect.

Question: How to iterate over rows so that I can apply the Blur effect. Or, even better, how can I bind a Effect to a row?

This is my code that only works when applying effect on startup:

    private void dg_LoadingRow(object sender, DataGridRowEventArgs e)
    {
        if (true) // Logic for figuring out if a row should be blur'ed
            e.Row.Effect = new BlurEffect { Radius = 8 };
    }

Thanks for any help

我找到了一个解决方案：

像这样绑定到 DataGridCellPresenter 上的 Effect 属性：

<sdk:DataGridCellsPresenter x:Name="CellsPresenter" Grid.Column="1" sdk:DataGridFrozenGrid.IsFrozen="True" Effect="{Binding ., Converter={StaticResource BlurConverter}}"/>

转换器很简单：

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
    // Some logic...
    return new BlurEffect { Radius = 8 }; 
}

I found a solution to this:

Bind to the Effect property on the DataGridCellPresenter like this:

<sdk:DataGridCellsPresenter x:Name="CellsPresenter" Grid.Column="1" sdk:DataGridFrozenGrid.IsFrozen="True" Effect="{Binding ., Converter={StaticResource BlurConverter}}"/>

And the converter simply:

public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
{
    // Some logic...
    return new BlurEffect { Radius = 8 }; 
}
