GridView Resposive Design

Hello, Kashif,    

If you need to add row by row in RadGridView and this behavior to be noticeable for the end user, I would suggest you to use a timer. Please refer to the below code snippet which result is illustrated in the attached gif file:

        BindingList<Item> items = new BindingList<Item>();

        public RadForm1()
        {
            InitializeComponent();
            this.radGridView1.DataSource = items;
            this.radGridView1.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            items.Add(new Item(items.Count, "Item" + items.Count));
        }

        public class Item
        {
            public int Id { get; set; }

            public string Name { get; set; }

            public Item(int id, string name)
            {
                this.Id = id;
                this.Name = name;
            }
        }

        private void radButton1_Click(object sender, EventArgs e)
        {
            if (!this.timer1.Enabled)
            {
                this.timer1.Start();
            }
            else
            {
                this.timer1.Stop();
            }
        }

As to the waiting indicator, you can use RadWaitingBar which allows you to associate it to any control indicating its load time. The following help article demonstrates a sample approach: https://docs.telerik.com/devtools/winforms/controls/track-and-status-controls/waitingbar/associated-control

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

Using Associated Control with ONE control is working fine.

Can we Use associated control property for the whole form, including other controls(like buttons, textboxes etc) on the form.

Or there will any other method for doing this.

Thank you for the suggestion.

Using waiting bar in timer control is working perfectly.

Now an other requirement.

I'm Assigning DataTable to GridView Data Source Property.

How to show progress/WaitingBar while form is Fetching the Data in the Data table and assigning it to Gridview.DataSource
