The challenge with using Telerik Rad Textboxes in conjunction with JavaScript

I am facing an issue where the server data is not displayed in a Rad Textbox until I click on it using JavaScript. The data is being populated correctly inside the textbox, but it remains invisible until clicked.

  function fillTextBox(name, sku, plu, nameBox, sBox, pBox) {

                sBox.value = sku;
                pBox.value = plu;
                nameBox.value = name;
                $find('mdlPopup').hide();
            }

I am passing parameters in the button's onClick event within a Gridview like this:

  button.Attributes.Add("onClick", string.Format("fillTextBox('{0}',{1},{2},{3},{4},{5});",
                e.Row.Cells[0].Text.Trim(), e.Row.Cells[1].Text.Trim(), e.Row.Cells[2].Text.Trim(), FormViewAccident.FindControl("prodBox").ClientID,
                FormViewAccident.FindControl("SBox").ClientID, FormViewAccident.FindControl("PBox").ClientID));

Although this method works, the issue persists where the textbox needs to be clicked for the data to display. Using a regular asp.net textbox works flawlessly, but it's not suitable for this particular project.

Answer №1

Ensure that nameBox is directly linked to the client-side RadTextBox object, and not its corresponding DOM element (tip: opt for the $find method over $get).

Answer №2

To update the value, utilize Telerik's client-side API.

Replace nameBox.value = name with nameBox.set_value(name).

For further details, refer to the demonstration.
