How to set Auto for HeaderRowHeight property?

[Daniel]

Hi,

I want to set Auto for HeaderRowHeight property of SfDataGrid.

Some of my headers contain long string and I want to wrap the text (I've written Template for this), but it isn't displayed because height of header row is too small.

I can set HeaderRowHeight property with some value, but I'm not so sure it will look appropriate in different DPI of screens etc.

Hi Daniel,

Thank you for contacting Syncfusion Support.

We have analyzed your query. You can achieved your requirement to increase the header row height by getting the Formatted text height and set that height to Header row height in Grid loaded event like below code example,

Code Example[C#]:

void datagrid_Loaded(object sender, RoutedEventArgs e)
        {
            var row = this.datagrid.GetRowGenerator().Items[0];
            FormattedText formattedtext = null;
            var visibleColumns = row.GetType().GetProperty("VisibleColumns", BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic).GetValue(row, null) as List<DataColumnBase>;
 
            foreach (var item in visibleColumns)
            {
                double maxheight = 0.0;
                string[] columnNames = item.GridColumn.HeaderText.Split(' ');
                foreach (var columnName in columnNames)
                {
                    formattedtext = new FormattedText(columnName,
                                System.Globalization.CultureInfo.CurrentCulture, datagrid.FlowDirection,
                                new Typeface(datagrid.FontFamily, datagrid.FontStyle, FontWeights.Normal,
                                    new FontStretch()), 14, Brushes.Black);
                    maxheight += formattedtext.Height;
                }
                if (datagrid.HeaderRowHeight < maxheight)
                    datagrid.HeaderRowHeight = maxheight;
            }
        }
