Problem While use RequiredFieldValidator & AjaxUpdatedControls

[Prabha]

hai All,

         I have used a page with "RequiredFieldValidator" . And also i need to use AjaxUpdatedControls for avoid reload entire page. 
      <rad:RadAjaxManager ID="RadAjaxManager1" runat="server">
    <AjaxSettings>
        <rad:AjaxSetting AjaxControlID="SaveBtn">
            <UpdatedControls>
                <%--  <rad:AjaxUpdatedControl ControlID="namevalidate" />
            </UpdatedControls>
        </rad:AjaxSetting>
</rad:RadAjaxManager>

  <rad:RadTextBox ID="rtxtname" runat="server" Width="120px">
            </rad:RadTextBox>
            <asp:RequiredFieldValidator ID="namevalidate
" ControlToValidate="rtxtmoctypename"
                runat="server" ErrorMessage="MOC Type Name is required" Display="Static">*</asp:RequiredFieldValidator>
   <asp:Button ID="SaveBtn" runat="server" CssClass="FormButton" Text="Save" Width="59px"
                CommandName="Insert" OnClick="SaveBtn_Click" />
Even i will give data in the  rtxtname, the error message coming. what to do for that?

Hello Prabha,

I have created a sample RadGrid web site to test the described behavior. Can you please run the attached application and verify that it works as expected on your side, too?

     Thank you for your reply. Actually i my problem is in Popup screens. In Popup(using RadWindowManager) only the page blinking is happens. And also that popup controls are placed in .ascx page. That is , .aspx page refer an .ascx which is my popup.

My coding is(.ascx):
----------------------------------------
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="AddMOCActionItem.ascx.cs"
    Inherits="Sampige.Web.iprocessWebPortal.MOC.Administration.UserControls.AddMOCActionItem" %>
<asp:ValidationSummary ID="ValidationSummary1" runat="server" ShowMessageBox="false"
    HeaderText="The following error(s) have occurred:" ShowSummary="true" />
<rad:RadScriptManager ID="RadScriptManager1" runat="server">
    <Scripts>
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
        <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
    </Scripts>
</rad:RadScriptManager>
<rad:RadAjaxManager ID="RadAjaxManager1" runat="server" UpdatePanelsRenderMode="Inline">
    <AjaxSettings>
        <rad:AjaxSetting AjaxControlID="SaveBtn">
            <UpdatedControls>
                <rad:AjaxUpdatedControl ControlID="rtxtmocactionitem" />
            </UpdatedControls>
        </rad:AjaxSetting>
    </AjaxSettings>
</rad:RadAjaxManager>

<table class="form" cellspacing="1" cellpadding="1" border="0" style="width: 100%">
    <tr>      
        <td>
            <rad:RadTextBox ID="rtxtmocactionitem" runat="server" TextMode="MultiLine" Width="200px"
                MaxLength="2000">
            </rad:RadTextBox>
            <asp:RequiredFieldValidator ID="mocactionitemValidator" ControlToValidate="rtxtmocactionitem"
                runat="server" ErrorMessage="Workflow Action Item is required" Display="Static">*</asp:RequiredFieldValidator>
        </td>
    </tr>
    <tr>
        <td colspan="4" align="center">
            <asp:Button ID="SaveBtn" runat="server" CssClass="FormButton" Text="Save" Width="59px"
                OnClick="SaveBtn_Click" />        
        </td>
    </tr>

Hi Prabha,

Please have a look into the following code snippet which works fine at my end.

ASPX:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
</telerik:RadAjaxManager>
<telerik:RadButton ID="RadButton1" AutoPostBack="false" runat="server" Text="show window"
    OnClientClicked="click">
</telerik:RadButton>
<telerik:RadWindowManager ID="RadWindowManager1" runat="server">
    <Windows>
        <telerik:RadWindow ID="RadWindow1" runat="server">
            <ContentTemplate>
                <uc1:WebUserControl4 ID="WebUserControl41" runat="server" />
            </ContentTemplate>
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>
</telerik:RadWindow>

JavaScript  in ASPX page:

<script type="text/javascript">
    function click(sender, args) {
        var win = $find("<%=RadWindow1.ClientID %>");
        win.Show();
    }
</script>

ASCX:

<asp:ValidationSummary ID="ValidationSummary1" runat="server" ShowMessageBox="false"
    HeaderText="The following error(s) have occurred:" ShowSummary="true" />
<telerik:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">
    <AjaxSettings>
        <telerik:AjaxSetting AjaxControlID="SaveBtn">
            <UpdatedControls>
                <telerik:AjaxUpdatedControl ControlID="rtxtmocactionitem" />
            </UpdatedControls>
        </telerik:AjaxSetting>
    </AjaxSettings>
</telerik:RadAjaxManagerProxy>
<table class="form" cellspacing="1" cellpadding="1" border="0" style="width: 100%">
    <tr>
        <td>
            <telerik:RadTextBox ID="rtxtmocactionitem" runat="server" TextMode="MultiLine" Width="200px"
                MaxLength="2000">
            </telerik:RadTextBox>
            <asp:RequiredFieldValidator ID="mocactionitemValidator" ControlToValidate="rtxtmocactionitem"
                runat="server" ErrorMessage="Workflow Action Item is required" Display="Static">*</asp:RequiredFieldValidator>
        </td>
    </tr>
    <tr>
        <td colspan="4" align="center">
            <asp:Button ID="SaveBtn" runat="server" CssClass="FormButton" Text="Save" Width="59px" />
        </td>
    </tr>
</table>

Let me know if you have any concern.
Thanks,
Shinu.

How can we use required field validator on User Control in aspx page?

[Eyup]

Hello Prabha,

You can set the ControlToValidate property of the RequiredFieldValidator programmatically:

protected void Page_Init(object sender, EventArgs e)
{
    WebUserControlSample userControl = Page.LoadControl("~/WebUserControlSample.ascx") as WebUserControlSample;
    Form.Controls.Add(userControl);
    RequiredFieldValidator1.ControlToValidate = userControl.FindControl("TextBox1").UniqueID;
}

Hope this helps.

Hi All,

     Is it possible to assign multiple value field/tag for a node in Radtreeview? i had try with Attribute property but does not like what i need. is there any other property for this ?

[Nencho]

Hello Prabha,

Using the AttributesCollection of a certain node is the correct approach to persist additional information (multiple values) of the Node. Could you elaborate a bit more on your scenario and on the issue you had faced, using the AttributesCollection?
