onblur and onfocus attributes for textbox created progrmatically in vb.net

Question

how do i put the onblur and onfocus attributes on a textbox created programatically? here's my code -

td = New HtmlTableCell td.Style.Add("padding-bottom", "5px") Dim txtbox As New TextBox txtbox.Style.Add("width", "96%") txtbox.ID = "ename" td.Controls.Add(txtbox) tr.Cells.Add(td) td.Style.Add("padding-top", "5px")

now i want to add onblur and onfocus. is there something like? --

            txtbox.attributes.Add("onblur","Enter Name")
            txtbox.attributes.Add("onfocus","")

i tried this, and doesn work. does anyone know how to do this?

onblur and onfocus are JavaScript event handlers. Their values must be valid JavaScript. You're probably looking for something like this:

txtbox.attributes.Add("onblur","this.value = 'Enter Name';")
txtbox.attributes.Add("onfocus","this.value = '';")
