New option in TextImageRelation

Hi. it was great to see the option "ImageOnly", for columns of small width, where only the image is placed in the header, and the "HederText" property was set, for the correct display of the grouping field

GridViewDataColumn column;

column.HeaderText = "Счет";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;



GridViewDataColumn column;

column.HeaderText = "";

column.HeaderImage = ...; // some img

column.TextImageRelation = TextImageRelation.Overlay;

it’s impossible to choose one thing, either an ugly header, or a grouping without a description

Hello, Alex,    

It is possible to achieve image only display style in the header cells via the ViewCellFormatting event. I have prepared a sample code snippet for your reference: 
        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.ViewCellFormatting += radGridView1_ViewCellFormatting;
            GridViewTextBoxColumn contactNameColumn = this.radGridView1.Columns["ContactName"] as GridViewTextBoxColumn;
            contactNameColumn.HeaderImage = Properties.Resources.AnneDodsworth22;
            this.radGridView1.MasterTemplate.ShowGroupedColumns = true;
        }

        private void radGridView1_ViewCellFormatting(object sender, CellFormattingEventArgs e)
        {
            if (e.Row is GridViewTableHeaderRowInfo && e.Column.Name == "ContactName")
            {
                e.CellElement.DrawText = false;
            }
            else
            {
                e.CellElement.ResetValue(LightVisualElement.DrawTextProperty, ValueResetFlags.Local);
            }
        }

Please give it a try and see how it works on your end.

I hope this information helps. If you need any further assistance please don't hesitate to contact me.
