How to override control's values in Edit Form

I'm using Edit Form to insert/edit items. The problem I'm running into is when I try to edit a row, it's using the same form and some of the controls are not set to what data item for that grid item actually has. When in the life cycle can I set selected values for my RadComboBoxes and RadNumericTextBoxes, any code examples?

Loading Panel and Rad Ajax Manager

Hi

I have a Page A where on button click, I display another page B using radwindow dialog. When button save is clicked on page B, some data is processing, Page B is closed and then page is redirected to Page A.
In this scenario, i refresh page A with radajaxmanager sometimes it takes considerable amount of time and user may not know if the processing is going on.

I wan to display a loading panel on Page A once the Dialog of page B is closed, I am using DefaultLoadingPanelID in my radajaxmanager but the loading panel is not displaying. I dont know why :(

[Solved] TreeList not rendering styles

Hi,

I have a treelist control loaded dynamically inside RadDock. When the dock is expanded the controls are loaded but the styles are not rendered. I also checked the site and found the EnableAjaxSkinRendering property of RadDock and set tat to true.
Even tat didn't work. This problem exists only in Internet Explorer. Please refer the image attached below.

Thanks,
Karthik

Dynamically hide GridButtonColumn in RadGrid

Hi,

I have a RadGrid that contains two GridButtonColumns of HeaderButtonType LinkButton. I would like to control the behavior to dynamically hide one column and show the other and vice versa.

In addition, in one of the circumstances there is an additional GridBoundColumn that I would like to hide.

How do I do this? Also, can I do it in the ItemDataBound method or does it need to be done in a PreRender method?

In the Grid below, I want to show the RequestorName and RequestorPd columns and hide the InstitutionName column in one case and in the other I want to show the InstitutionName column and hide the RequestorName and RequestorPd columns.

<telerik:RadGrid ID="RadGridPrescriber" runat="server"

AutoGenerateColumns="false" AllowSorting="True" AllowPaging="false" Skin="Simple" ClientSettings-Resizing-AllowColumnResize="true"

ItemStyle-Wrap="false" Width="95%" HeaderStyle-Wrap="false" PageSize="25"

OnNeedDataSource="RadGridPrescriber_NeedDataSource" OnItemDataBound="RadGridPrescriber_ItemDataBound" OnItemCommand="RadGridPrescriber_ItemCommand">

<ClientSettings>

<Scrolling AllowScroll="true" UseStaticHeaders="true" />

</ClientSettings>

<ExportSettings ExportOnlyData="false" IgnorePaging="true" OpenInNewWindow="true" />

<MasterTableView TableLayout="Fixed" AllowMultiColumnSorting="true" DataKeyNames="RequestorSln" ShowFooter="false" PagerStyle-AlwaysVisible="false" CommandItemDisplay="Top" >

<NoRecordsTemplate>

<asp:Label ID="lblMsg" runat="server" Text="No Records found"></asp:Label>

</NoRecordsTemplate>

<CommandItemSettings ShowExportToPdfButton="true" ShowExportToCsvButton="true" ShowExportToExcelButton="true" ShowRefreshButton="false" ShowAddNewRecordButton="false" />

<Columns>

<telerik:GridButtonColumn HeaderText="Name" HeaderButtonType="LinkButton" UniqueName="RequestorName" CommandName="GetByRequestorSLN" DataTextField="RequestorName" ItemStyle-HorizontalAlign="Left" />

<telerik:GridButtonColumn HeaderText="Name" HeaderButtonType="LinkButton" UniqueName="InstitutionName" CommandName="GetByRequestorSLN" DataTextField="InstitutionName" ItemStyle-HorizontalAlign="Left" />

<telerik:GridBoundColumn HeaderText="PD" HeaderButtonType="TextButton" DataField="RequestorPd" ItemStyle-HorizontalAlign="Left" />

</Columns>

</MasterTableView>

</telerik:RadGrid>

Thanks,

[Solved] Problem with empty RadComboBoxContext

Hi all,

I'm facing the problem while using the RadComboBox. I've used the example from Telerik Demo to populate RadComboBox with data on demant in a new empty project. And when the control calls for the WCF service for data the RadComboBoxContext parameter is empty.
Can you please advice me what I'm doing wrong?

ASPX code:

<%@ Page Title="Home Page" Language="C#" MasterPageFile="~/Site.master" AutoEventWireup="true"

CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %>

<%@ Register TagPrefix="telerik" Namespace="Telerik.Web.UI" Assembly="Telerik.Web.UI" %>

<asp:Content ID="HeaderContent" runat="server" ContentPlaceHolderID="HeadContent">

</asp:Content>

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

<div>

<telerik:RadScriptManager ID="RadScriptManager1" runat="server">

</telerik:RadScriptManager>

<telerik:RadComboBox runat="server" ID="RadComboBox1" Height="100px"

EnableLoadOnDemand="true" ShowMoreResultsBox="true" EnableVirtualScrolling="true"

EmptyMessage="Type here ...">

<WebServiceSettings Path="~/ComboBoxWcfService.svc" Method="LoadData" />

</telerik:RadComboBox>

</div>

<asp:LinqDataSource ID="LinqDataSource1" runat="server">

</asp:LinqDataSource>

</asp:Content

>





WCF code:


[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class ComboBoxWcfService {
    public void DoWork()
    {
    }
    [OperationContract]
    public RadComboBoxData LoadData(RadComboBoxContext context)
    {
        //The RadComboBoxData object contains all required information for load on demand:
        // - the items 
        // - are there more items in case of paging
        // - status message to be displayed (which is optional)
 
        AdventureWorksDataContext northwind = new AdventureWorksDataContext();
 
 
         
        RadComboBoxData result = new RadComboBoxData();
 
        //Get all items from the Customers table. This query will not be executed untill the ToArray method is called.
        var allCustomers = from customer in northwind.Customers
                           orderby customer.ContactName
                           select new RadComboBoxItemData
                           {
                               Text = customer.ContactName
                           };
 
 
        //In case the user typed something - filter the result set
        string text = context.Text;
        if (!String.IsNullOrEmpty(text))
        {
            allCustomers = allCustomers.Where(item => item.Text.StartsWith(text));
        }
        //Perform the paging
        // - first skip the amount of items already populated
        // - take the next 10 items
        int numberOfItems = context.NumberOfItems;
        var customers = allCustomers.Skip(numberOfItems).Take(10);
 
        //This will execute the database query and return the data as an array of RadComboBoxItemData objects
        result.Items = customers.ToArray();
 
 
        int endOffset = numberOfItems + customers.Count();
        int totalCount = allCustomers.Count();
 
        //Check if all items are populated (this is the last page)
        if (endOffset == totalCount)
            result.EndOfItems = true;
 
        //Initialize the status message
        result.Message = String.Format("Items <b>1</b>-<b>{0}</b> out of <b>{1}</b>",
                                       endOffset, totalCount);
 
        return result;
    }
}



WebConfig:


<service behaviorConfiguration="metadataAndDebug" name="WebApplication1.ComboBoxWcfService">
