wpf 字体大小不适用于数据网格列标题

Font size not applied to datagrid columnheader

提问by deathrace

I have a wpf datagrid in which I am adding all the columns and style through C#.

我有一个 wpf 数据网格，我在其中通过 C# 添加了所有列和样式。

I have applied ColumnHeaderStyle as follows:

我已应用 ColumnHeaderStyle 如下：

1. written setter as :

   var fontSizeSetter = new Setter {Property = Control.FontSizeProperty, Value = Convert.ToDouble(font.Size)};

2. Style as:

           var headerStyle = new Style();
           headerStyle.Setters.Add(fontSetter);
           headerStyle.Setters.Add(fontSizeSetter);
           headerStyle.Setters.Add(fontStyleSetter);
           headerStyle.Setters.Add(fontWeightSetter);
   

3. Applied it to my Datagrid'sColumnHeaderStyle as:

1. 写二传手为：

   var fontSizeSetter = new Setter {Property = Control.FontSizeProperty, Value = Convert.ToDouble(font.Size)};

2. 风格为：

           var headerStyle = new Style();
           headerStyle.Setters.Add(fontSetter);
           headerStyle.Setters.Add(fontSizeSetter);
           headerStyle.Setters.Add(fontStyleSetter);
           headerStyle.Setters.Add(fontWeightSetter);
   

3. 将它应用到我的Datagrid'sColumnHeaderStyle 作为：

view.DataGrid.ColumnHeaderStyle = headerStyle;

view.DataGrid.ColumnHeaderStyle = headerStyle;

Current problem: now, when I set FontFamily& FontStyleit gets applied. but column Header textsizeremains same. It does not get updated.

当前问题：现在，当我设置FontFamily和FontStyle 时，它会被应用。但列标题文本大小保持不变。它不会更新。

整个方法：

private static void ConfigureFontsForDataGrid(Views.StatusMonitor view, StatusMonitorAgencyFontType font)
        {
            var fontfamily = new FontFamily(font.Font);
            var fontSetter = new Setter { Property = Control.FontFamilyProperty, Value = fontfamily };
            var fontSizeSetter = new Setter { Property = Control.FontSizeProperty, Value = Convert.ToDouble(font.Size) };
            var fontStyleSetter = new Setter { Property = Control.FontStyleProperty };
            var fontWeightSetter = new Setter { Property = Control.FontWeightProperty };

            // Defaults
            fontWeightSetter.Value = FontWeights.Regular;
            fontStyleSetter.Value = FontStyles.Normal;

            switch (font.Style)
            {
                case "Regular":
                    fontWeightSetter.Value = FontWeights.Regular;
                    fontStyleSetter.Value = FontStyles.Normal;
                    break;

                case "Bold Italic":
                    fontWeightSetter.Value = FontWeights.Bold;
                    fontStyleSetter.Value = FontStyles.Italic;
                    break;
            }

            //Configuring data grid cell font
            view.DataGrid.CellStyle.Setters.Add(fontSetter);
            view.DataGrid.CellStyle.Setters.Add(fontSizeSetter);
            view.DataGrid.CellStyle.Setters.Add(fontStyleSetter);
            view.DataGrid.CellStyle.Setters.Add(fontWeightSetter);

            //Configuring data grid column header font
            view.DataGrid.ColumnHeaderStyle.Setters.Add(fontSetter);
            view.DataGrid.ColumnHeaderStyle.Setters.Add(fontSizeSetter);
            view.DataGrid.ColumnHeaderStyle.Setters.Add(fontStyleSetter);
            view.DataGrid.ColumnHeaderStyle.Setters.Add(fontWeightSetter);
        }

I wrote following data template in my datagrid resources. It works.

我在我的数据网格资源中编写了以下数据模板。有用。

<DataTemplate DataType="{x:Type System:String}">
                <TextBlock Text="{Binding}">
                    <TextBlock.Resources>
                        <Style TargetType="{x:Type TextBlock}">
                            <Setter Property="FontFamily" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGridColumnHeader}, Path=FontFamily}" />
                            <Setter Property="FontSize" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGridColumnHeader}, Path=FontSize}" />
                            <Setter Property="FontStyle" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGridColumnHeader}, Path=FontStyle}"/>
                            <Setter Property="FontWeight" Value="{Binding RelativeSource={RelativeSource AncestorType=DataGridColumnHeader}, Path=FontWeight}"/>
                        </Style>
                    </TextBlock.Resources>
                </TextBlock>
            </DataTemplate>

Can you try below code.

你可以试试下面的代码。

        var headerStyle = new Style();
        Setter fontSetter = new Setter { Property = Control.FontFamilyProperty, Value = new FontFamily("Calibri") };
        headerStyle.Setters.Add(fontSetter);

        Setter fontSizeSetter = new Setter { Property = Control.FontSizeProperty, Value = Convert.ToDouble(20) };
        headerStyle.Setters.Add(fontSizeSetter);

        Setter fontStyleSetter = new Setter { Property = Control.FontStyleProperty, Value = FontStyles.Italic };
        headerStyle.Setters.Add(fontStyleSetter);

        Setter fontWeightSetter = new Setter { Property = Control.FontWeightProperty, Value = FontWeights.Bold };
        headerStyle.Setters.Add(fontWeightSetter);

        myGrid.ColumnHeaderStyle = headerStyle;
