Floating labels in Telerik winforms

Hello,

Please have in mind that both RadTextBox and RadTextBoxControl have the embedded labels and you only need to set the ShowEmbeddedLabel property to “true”.  RadDropDownList internally uses a TextBox as well. I have prepared a sample code snippet demonstrating how to enable the embedded label for it. The attached gif file illustrates the achieved result:

            this.radDropDownList1.DropDownStyle = RadDropDownStyle.DropDown;
            this.radDropDownList1.DropDownListElement.TextBox.ShowEmbeddedLabel = true;
            this.radDropDownList1.DropDownListElement.TextBox.EmbeddedLabel.Text = "Enter data";

            for (int i = 0; i < 10; i++)
            {
                this.radDropDownList1.Items.Add("Item"+i);
            }
            this.radDropDownList1.SelectedItem = null;

It is very important to note that this functionality was introduced in R2 2021. Even though this feature seems to be simple, its implementation is not so easy to accomplish to give any general tips. However, you can have a look at the following KB article which demonstrates a sample approach:

Feel free to upgrade in order to benefit from the introduced improvement.

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