How to pinned column when Viewdefinition value of radDataGridview using Htmlview.

[Kei]

I created the ViewDefinition value of RadGridView using HtmlViewDefinition, and I want to give the Pinned property to the first, second, and third columns.
However, the result is created by duplicating three columns as in the screenshot.

How to fix it?

 Hello, Kei,  

By default, the context menu items for pinning the columns is eligible only for TableViewRowLayout and the root level groups of the ColumnGroupsViewDefinition. For the HtmlViewRowLayout, pinning is not allowed since the columns may be spanned among different rows/columns. 

I would recommend you to consider using the ColumnGroupsViewDefinition: https://docs.telerik.com/devtools/winforms/controls/gridview/view-definitions/column-groups-view

        private void RadForm1_Load(object sender, EventArgs e)
        { 
            this.customersTableAdapter.Fill(this.nwindDataSet.Customers);
            this.radGridView1.DataSource = this.customersBindingSource;
            this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;

            ColumnGroupsViewDefinition view = new ColumnGroupsViewDefinition();
            view.ColumnGroups.Add(new GridViewColumnGroup("Customer Contact"));
            view.ColumnGroups.Add(new GridViewColumnGroup("Details"));
            view.ColumnGroups[1].Groups.Add(new GridViewColumnGroup("Address"));
            view.ColumnGroups[1].Groups.Add(new GridViewColumnGroup("Contact"));
            view.ColumnGroups[0].Rows.Add(new GridViewColumnGroupRow());
            view.ColumnGroups[0].Rows[0].ColumnNames.Add("CompanyName");
            view.ColumnGroups[0].Rows[0].ColumnNames.Add("ContactName");
            view.ColumnGroups[0].Rows[0].ColumnNames.Add("ContactTitle");
            view.ColumnGroups[1].Groups[0].Rows.Add(new GridViewColumnGroupRow());
            view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("Address");
            view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("City");
            view.ColumnGroups[1].Groups[0].Rows[0].ColumnNames.Add("Country");
            view.ColumnGroups[1].Groups[1].Rows.Add(new GridViewColumnGroupRow());
            view.ColumnGroups[1].Groups[1].Rows[0].ColumnNames.Add("Phone");
            view.ColumnGroups[1].Groups[1].Rows[0].ColumnNames.Add("Fax");
            radGridView1.ViewDefinition = view;

            view.ColumnGroups[1].PinPosition = PinnedColumnPosition.Left;
        }

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