I have successfully created functionality that mostly models what I'm trying
to do - which is dynamically insert controls into a user control (ascx), and
insert validation controls, also dynamically, for some of the inserted
controls.
The controls (e.g., textBoxes) get created correctly and viewstate is
maintained across postbacks, etc - BUT there is an issue with the validation
controls.
The validation controls, themselves are working - EXCEPT that
1. They do their job only during a Postback (i.e., the page must actually
post back in order for validation to occur); that is, client-side validation
is not happening (i.e., it's not preventing a postback when it should).
2. The validation summary control is apparently not working at all. It
should pop up a message box, but it does nothing.
My question is how to resolve/fix these two issues: I want the validation to
occur client-side (in addition to the default server-side validation), and I
want the validation summary control to work.
FWIW here is my code:
Hosting ASCX:
<%@ Control CodeBehind="ucF orm1.ascx.cs" Language="c#"
AutoEventWireup ="false" Inherits="MyAss embly.ucForm1" %>
<asp:PlaceHolde r id="FormPlaceHo lder" runat="server"> </asp:PlaceHolder >
<table align="center"> <tr><td><asp:Bu tton id="btnSave"
EnableViewState ="false" CommandName="bt nSave" Visible="true" Width="100px"
runat="server" Text="Save"></asp:Button></td></tr></table>
Relevant Code Behind:
The method named InsertDynamicCo ntrols() is called from the OnInit() event
ucForm1.
private void InsertDynamicCo ntrols () {
Literal spacer = new Literal();
spacer.Text = " ";
// This is where I have all the logic that inserts the FORM controls into
the Placeholder
string s = "<table border=2><tr><t d>Yo</td><tr><td>";
s += "<asp:TextB ox id=\"txtBox1\" EnableViewState =\"false\"
Width=\"300px\" runat=\"server\ "></asp:TextBox>";
s += "</td></tr></tr><tr><td>Some Value</td></tr><tr><td>Othe r
Value</td></tr></table>";
System.Web.UI.C ontrol c = ParseControl(s) ;
FormPlaceHolder .Controls.Add(c );
RequiredFieldVa lidator requiredFieldVa lidator = new
RequiredFieldVa lidator();
requiredFieldVa lidator.Control ToValidate = "txtBox1";
requiredFieldVa lidator.EnableC lientScript = true;
requiredFieldVa lidator.Enabled = true;
requiredFieldVa lidator.ErrorMe ssage = "Yo - You gotta enter something
man!";
requiredFieldVa lidator.ID = "RequiredFieldV alidator_Title" ;
requiredFieldVa lidator.Text = "*";
requiredFieldVa lidator.EnableC lientScript = true;
FormPlaceHolder .Controls.Add(s pacer);
FormPlaceHolder .Controls.Add(r equiredFieldVal idator);
ValidationSumma ry validationSumma ry = new ValidationSumma ry();
validationSumma ry.DisplayMode =
System.Web.UI.W ebControls.Vali dationSummaryDi splayMode.Bulle tList;
validationSumma ry.ShowMessageB ox = true;
validationSumma ry.HeaderText = "These things must be fixed before you can
proceed:";
validationSumma ry.ShowSummary = false;
validationSumma ry.ID = "validSummary1" ;
validationSumma ry.EnableClient Script = true;
FormPlaceHolder .Controls.Add(s pacer);
FormPlaceHolder .Controls.Add(v alidationSummar y);
}
Thanks!
