Hi all,

We are implementing a RadGrid with a templated edit form.  We've placed a custom user control within the edit form template, like this:

<EditFormSettings EditFormType="Template" >
<FormStyle 
CssClass="GridForm"></FormStyle>
<FormTemplate>
<uc:UserRights 
ID="urEditForm" 
    UserID='<%# (Container is GridEditFormInsertItem) ? 0 : 
DataBinder.Eval(Container.DataItem,"ID") %>'  
    runat="server"/>
</FormTemplate>
</EditFormSettings>

As you can see, we've set it up so that the user control's UserID property is set to 0 when inserting, or to the actual value if editing.

Here's what we want to happen:

  • User control's ID is initially set to 0 when first opening the insert form.
  • When the insert action is performed, get the DataKey value from the inserted row (int Identity).
  • Re-set the control's UserID property to that DataKey value
  • Call the Update public method on the control.

My question is: what event can I hook that will provide me both access to the identity column value of the newly inserted item AND still let me trigger the public method on my user control so that it can update what it needs to update?

(There is much more to the form than simply the user control.  We are using mostly databound controls on the form template.  This user control is somewhat more complex and needs to be reusable, which is why we chose to compartmentalize it into its own control.)

Thanks!

that may be, thanks for your help

Hello guys

I'm trying to create or activate or clone a raddatepicker dynamically using javascript and webservices
Now I tried 2 scenarios
-Render the control using webservices like this, the control appears ok, but nothing work on it (no validation, dropdown button...) and the rendered string is pretty massive, is there a function that I could use to bind/initialize the control to static scripts?

<WebMethod()> _
    Public Function HelloWorld(ByVal s As String) As String
         Dim np As Page = New Page
        np.Controls.Add(New Telerik.Web.UI.RadScriptManager)
        Dim d As Telerik.Web.UI.RadDatePicker = New Telerik.Web.UI.RadDatePicker
        d.ID = "ddd"
        d.EnableViewState = False
        d.DbSelectedDate = Now
        d.RegisterWithScriptManager = False
        d.Page = np
 
        Dim tw As System.IO.StringWriter = New System.IO.StringWriter()
        Dim hw As HtmlTextWriter = New HtmlTextWriter(tw)
        d.RenderControl(hw)
        Return tw.ToString()
    End Function


<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="WebApplication2.WebForm1" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<head runat="server">
<script type="text/javascript" src="http://code.jquery.com/jquery-1.5.min.js"></script>
<!--http://code.jquery.com/jquery-1.5.js-->
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
     <telerik:RadScriptManager ID="RadScriptManager1" runat="server"></telerik:RadScriptManager>
    <script language="javascript" type="text/javascript">
        function BC(s, e) {
            $.ajax({ url: "/Webservice1.asmx/HelloWorld?s=" + s.get_id(), success: function (result) {
                 //var nd = $("#RadDatePicker1")[0].cloneNode();
                //nd.id = "asd";
                $("#c")[0].innerHTML = result.text;
                //$("#c")[0].insertBefore($("#RadDatePicker1")[0]);
                //nd.style.visibility = "visible";
            }
            });
        }
                </script>
 
        <div id="c"></div>
    <div>
<!--        <telerik:RadDatePicker ID="RadDatePicker1" Runat="server"></telerik:RadDatePicker>-->
         
<telerik:RadButton ID="RadButton1" runat="server" onclientclicked="BC"
            AutoPostBack="False">
</telerik:RadButton>
    </div>
    </form>
</body>
</html>


-Then I tryed the cloneNode function, but I can't even make the raddatepicker appear
var nd = $("#RadDatePicker1")[0].cloneNode(true);
                
nd.id = "asd";
               $("#c")[0].insertBefore(nd);
                //$("#c")[0].innerHTML = result.text;
Idealy, I guess I want to statically generate all the necessary scripts and one instance of each control that I need 
and then clone them dynamically with javascript as needed.

Is there a way to this? Is there a javascript telerik.ui.raddatepicker constructor?
You guys must have a way since there is a client side radgrid insert row

Thank you very much

I am wanting to validate based on a complex set of rules the entry into a textbox.  My preference would be to keep that validation on the server side in the code behind as the logic is written there already so I do not want to maintain it in javascript too for client side validation.  How can I call a validation method either on text change or focus via ajax with this control?

Hi Telerik Team

I would like to create my custom button with our own designed image. I copied the specific style into my own custom skin project and change the buttonsprite.gif with my own design, but my image is heigher than default one, so I have to overwrite the default common style. according to telerik suggest, it's not recommend to "important" keyword. So can someone tell me how can I overwrite the following style in my custom skin css file? I try to put my custom name in front of them, e.g. .RadButton_LongWithImage .rbSkinnedButton, but it doesn't work.

.rbSkinnedButton
{
    display: inline-block;
    position: relative;
    background-color: transparent;
    background-repeat: no-repeat;
    border: 0 none;
    height: 22px;
    text-align: center;
    text-decoration: none;
    white-space: nowrap;
    background-position: right 0;
    padding-right: 4px; /* this value is hacked for webkit */
}
 
 
.rbDecorated
{
    display: block;
    height: 22px;
    padding: 0 6px 0 10px;
    border: 0;
    text-align: center;
    background-position: left -22px;
    overflow: visible;
    background-color: transparent;
    outline: none;
    cursor: pointer;
    -wbkite-border-radius: 0; /* set default border-radius to 0 in mobile safari */
}

Hi ,
I am using a RadGrid and i have a RadCombo in one of the column.  That combo has  external call back.

When the radcombo box triggers the selected index changed event of server side.  There in the code behind based on condition
I want to change the focus to either the same combo or next control in the grid. How ever as the page refreshes the i am loosing the focus.  I want IsPostback to be "True" because i have some condition to check in serverside.  And the focus should move to the next control in the grid.

Please tell me how i can achieve this?
Code in server side:
if condition()
{
((RadComboBox)currentEditItem["AmendmentNumber"].FindControl("ddlAmendmentNos")).Focus()
}
else
{

currentEditItem["AmendmentPurpose"].Focus();
((RadTextBox)currentEditItem["AmendmentPurpose"].FindControl("txtPurpose")).Focus();
}

RadCombo Settings:
<rad:GridTemplateColumn UniqueName="AmendmentNumber" DataField="Number" HeaderText="Bylaw #" ItemStyle-Width="10%"><ItemTemplate> <rad:RadComboBox Height="200px" ID="ddlAmendmentNos" MaxLength="10" runat="server" ToolTip="Enter Bylaw Number"AllowCustomText="true" MarkFirstMatch="false" ShowToggleImage="False" SkinsPath="~/RadControls/ComboBox/Skins"Skin="LIComboBoxSkin" ShowMoreResultsBox="true" EnableLoadOnDemand="True" ExternalCallBackPage="AmendmentNosDropDownBox.aspx"OnClientFocus="OnClientFocus" Text='<%# Eval("Number")%>' DataTextField="Number" OnSelectedIndexChanged="ddlAmendmentNos_SelectedIndexChanged"DataValueField="ID" AutoPostBack="true" ShowDropDownOnTextboxClick="false"></rad:RadComboBox></ItemTemplate></rad:GridTemplateColumn>
