    What is the simplest way to call a javascript funcrtion from a GridViewHyperlinkColumn or a GridViewDynamicHyperlinkColumn (directly or with code behind?

    For now, I've created a custom column with an HyperlinkButton, but the UI rendering is not the same as the 2 out of  the box columns. What I would like to see is a Command implementation with parameters, similar to the GridViewDynamicHyperlinkColumn's NavigateUrlFormatString and NavigateUrlMemberPaths property.
       

    public class GridViewItemLinkColumn : GridViewDynamicHyperlinkColumn
    {
        public override FrameworkElement CreateCellElement(Telerik.Windows.Controls.GridView.GridViewCell cell, object dataItem)
        {
            this.BindingTarget = HyperlinkButton.ContentProperty;
            HyperlinkButton btn = new HyperlinkButton();
            btn.Click += new RoutedEventHandler(btn_Click);
            btn.SetBinding(this.BindingTarget, this.CreateValueBinding());
     
            return btn;
        }
     
        void btn_Click(object sender, RoutedEventArgs e)
        {
            string str = this.DataControl.Items.IndexOf(((HyperlinkButton)sender).DataContext).ToString();
        }
        private Binding CreateValueBinding()
        {
            Binding valueBinding = new Binding();
            valueBinding.Mode = BindingMode.TwoWay;
            valueBinding.NotifyOnValidationError = true;
            valueBinding.ValidatesOnExceptions = true;
            valueBinding.UpdateSourceTrigger = UpdateSourceTrigger.Explicit;
            valueBinding.Path = new PropertyPath(this.DataMemberBinding.Path.Path);
     
            return valueBinding;
        }
    }

    Hello,

     You can use also CellTemplate of GridViewDataColumn to declare desired HyperlinkButton.
