I have a User Control which consists of a TextBox with a few extras, but for purposes of this example just assuming it's a plain TextBox will be sufficient. I am calling this User Control from a Web Form and would like to be able to use a RequiredFieldValidator that basically would function the same as if I used it on a TextBox on the web form. How do I configure my User Control to handle this?
EDIT:
DatePicker.ascx
<asp:TextBox runat="server" ID="myControlTB">
DatePicker.ascx.cs
[ValidationProperty("Text")]
public partial class DatePicker : System.Web.UI.UserControl
{
public String Text { get { return myControlTB.Text; } set { myControlTB.Text = value; } }
protected void Page_Load(object sender, EventArgs e)
{
}
}
WebForm.aspx
<cu:UserControl runat="server" ID="myControl">
<asp:RequiredFieldValidator runat="server" errormessage="This is a required field." ControlToValidate="myControl">
<asp:Button ID="btnSubmit" runat="server" Text="Submit" onclick="btnSubmit_Click" />
WebForm.aspx.cs
protected void btnSubmit_Click(object sender, EventArgs e)
{
Page.Validate();
if (Page.IsValid)
{
// e-mail the form
}
