SearchBox Error

I'm programmatically binding data to a RadSearchBox [I get my data list back from a Service Reference] and I set the DataTextField and DataValueField, then I set the DataSource - all without errors. However, when I start typing in the search box, I receive a popup on the page: DataSource not set

What am I missing?

<telerik:RadSearchBox runat="server" ID="radTest" OnSearch="radTest_OnSearch"></telerik:RadSearchBox>

protected void Page_Load(object sender, EventArgs e)

{

if (!IsPostBack)

{

UserServiceClient client = new UserServiceClient();

var users = client.GetSecurityUsers().ToList();

radTest.DataTextField = "full_name";

radTest.DataValueField = "user_id";

radTest.DataSource = users;

}

protected void radTest_OnSearch(object sender, SearchBoxEventArgs e)

{

UserServiceClient client = new UserServiceClient();

var users = client.GetSecurityUsers().ToList();

if (!string.IsNullOrEmpty(e.Text))

{

users = users.Where(i => i.full_name.Contains(e.Text)).ToList();

}

radTest.DataTextField = "full_name";

radTest.DataValueField = "user_id";

radTest.DataSource = users;

}

[Solved] RadAjaxPanel GroupingText does not emit fieldset

A normal asp:Panel with GroupingText set should render as a fieldset with GroupingText's value as its legend. This code below works.

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:ScriptManager runat="server" ID="rsm"></asp:ScriptManager>

<asp:Panel ID="pnlMailingAddr" runat="server" meta:resourcekey="pnlMailingAddrResource1" Visible="True" ViewStateMode="Enabled" GroupingText="Mailing Address Information">

<table border="0px" cellpadding="5px" cellspacing="5px" width="100%">

<tr>

<td>John Legend

</td>

</tr>

</table>

</asp:Panel>

</div>

</form>

</body>

</html>

But the same code using the RadAjaxPanel does not.

<html xmlns="http://www.w3.org/1999/xhtml">

<head runat="server">

<title></title>

</head>

<body>

<form id="form1" runat="server">

<div>

<asp:ScriptManager runat="server" ID="rsm"></asp:ScriptManager>

<asp:RadAjaxPanel ID="pnlMailingAddr" runat="server" meta:resourcekey="pnlMailingAddrResource1" Visible="True" ViewStateMode="Enabled" GroupingText="Mailing Address Information">

<table border="0px" cellpadding="5px" cellspacing="5px" width="100%">

<tr>

<td>John Legend

</td>

</tr>

</table>

</asp:RadAjaxPanel>

</div>

</form>

</body>

</html>

ItemTemplate not working when buttons are dynamically added server-side

We have been using RadToolbar for a very long time, but until recently we had never used the ItemTemplate functionality.

While we can display the templates correctly, we are encountering a significant issue when the page is posted back: the templates are not rendered after postback completes.

After a significant amount of troubleshooting, we have tracked the issue down to dynamically added buttons. We have static templates for most toolbars (defined in a skin), but there are several cases where we need to dynamically add buttons to every toolbar rather than adjusting all of the skins.

As soon as we insert a new toolbar item after the templated items, the templated items will no longer render after a postback (we have not tried inserting before because that is not something that we need to do.

We have tried removing and re-adding the dynamic toolbar items and simply ignoring them if they already exist on a postback, but in both cases, the templated items are not rendered.

I have a sample project that demonstrates the issue, but am not allowed to attach it to this thread.

Appointment move problem

Hi,

My asp.net radscheduler loads custom appointments from an SQL Server database. I implemented the OnClientAppointmentMoveEnd (It calls a PageMethod to update the database) method to update the appointment when moving the appointment from one slot to another. Sometimes, not always, when i move the appointment, it moves back to the original slot, without showing errors. I´ve debbuged the code , and saw no errors. Could you help me with that?

Asp.net Version: 3.5
Telerik Version: 2013.1.417.35

Postback actual state on Load_Page event

Good day!

In the code snippet below I'm always getting RadListView1.SelectedValue from previous ViewState at Page_Load handler.
For example, when I press "3" in the listview, I get "" in LabelRadListView1SelectedValue. Next time I press "5" and get "3" and so on.

Why "RadListView1.SelectedValue" isn't actual at Page_Load event on PostBack?
For example, It's going well at Page_LoadComplete event. So why RadListView1 restored from ViewState after Page_Load event?
I'm confused. Please, help!

RadListVew.aspx:

<%@ Page Title="" Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="RadListView.aspx.cs" Inherits="RadListV" %>

<%@ Import Namespace="Telerik.Web.UI" %>

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="Server">

<telerik:RadListView runat="server" ID="RadListView1" ItemPlaceholderID="PlaceHolderListContainer" DataKeyNames="data">

<LayoutTemplate>

<asp:PlaceHolder ID="PlaceHolderListContainer" runat="server"></asp:PlaceHolder>

</LayoutTemplate>

<ItemTemplate>

<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Select">

<asp:Label runat="server" ID="Label1" Text='<%#Eval("data")%>' />

</asp:LinkButton>

</ItemTemplate>

<SelectedItemTemplate>

<span style="font-weight: bold;">

<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Select">

<asp:Label runat="server" ID="Label1" Text='<%#Eval("data")%>' />

</asp:LinkButton>

</span>

</SelectedItemTemplate>

</telerik:RadListView>

<div>

<asp:Label runat="server" ID="LabelRadListView1SelectedValue" />

</div>

</asp:Content

RadListVew.aspx.cs:

using System;

using System.Collections.Generic;

using System.Linq;

using Telerik.Web.UI;

public partial class RadListV : System.Web.UI.Page

{

class ListItem

{

public int data { get; set; }

}

List<ListItem> ListDataSource

{

get

{

return (List<ListItem>)Session["ListDataSource"];

}

set { Session["ListDataSource"] = value; }

}

protected void Page_Load(object sender, EventArgs e)

{

if (RadListView1.SelectedValue != null)

LabelRadListView1SelectedValue.Text = RadListView1.SelectedValue.ToString();

}

protected void Page_Init(object sender, EventArgs e)

{

ListDataSource = new List<ListItem>();

for (int i = 1; i < 5; i++)

{

ListDataSource.Add(new ListItem { data = i });

}

RadListView1.DataSource = ListDataSource;

Drop Down List in RadGrid

Hi,

I am trying to get a RadDropDownList to work within a RadGrid. Autogeneratecolumns are set to False and all columns have been set.

The first code snippet is the column I am having issues with. The second code snippet is the same column but doesn't offer the DropDownList feature.
Basically what I am trying to archive, is when a user is looking at the grid, they can easily change the "Team" without the need going to Edit > (Change record) > Update.

<telerik:GridTemplateColumn> <ItemTemplate> <telerik:RadDropDownList DataField="IDNO" DataSourceID="TeamFilterOptions" HeaderText="123" DataTextField="FieldAnswer" UniqueName="DocCategoryColumn3" runat="server" ID="ddlEditCategory" AutoPostBack="True"></telerik:RadDropDownList> </ItemTemplate> </telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="Team" HeaderText="Team" UniqueName="Team"> <FilterTemplate> <telerik:RadComboBox ID="RadListBoxTeam" DataSourceID="TeamFilterOptions" DataTextField="FieldAnswer" DataValueField="FieldAnswer" Height="200px" AppendDataBoundItems="true"

SelectedValue='<%# TryCast(Container,GridItem).OwnerTableView.GetColumn("Team").CurrentFilterValue %>'                            runat="server" OnClientSelectedIndexChanged="TeamIndexChange">                            <

Items> <telerik:RadComboBoxItem Text="All" /> </Items> </telerik:RadComboBox> <telerik:RadScriptBlock ID="RadScriptBlock1" runat="server"> <script type="text/javascript"

>                                function TeamIndexChange(sender, args) {                                    var tableView = $find("<%# TryCast(Container, GridItem).OwnerTableView.ClientID%>");                                    tableView.filter("Team", args.get_item().get_value(), "EqualTo");                                }                            </

script> </telerik:RadScriptBlock> </FilterTemplate> </telerik:GridBoundColumn>

My issues I am facing are
How do I get the item to display the correct text as it just displays the first record from the data source. i.e. pull the data from the RadGrid datasource, the DataTextField should get the "Team" field. When I try to bind the data it just says "System.Data.DataRowView".
Once the user changes the value from the Drop Down List how do I retrieve that value in the code behind (VB.net but C# is fine), I cannot find anything relating to CommandName?

Thanks,
Alex
