Here is my scenerio. I have a 2 column combobox. Column 1 holds an ID number, column 2 holds a name. The combobox text/value properties are set to the ID number so the ID number will display in the combobox. We have a client that wants the ID number to display but would like to search by the name in column 2. I know how to do the items requested event using the combobox text (e.text) as the search value. How do you use data from the 2nd column as the search criteria and have the combobox auto fill as a user starts typing a name. Is this even possible?

Indent/Outdent are flawed

I have a problem -- and a bone to pick.

First of all, I don't recall reading about a change to the Indent/Outdent behaviour in any of the release notes over the last few years. I have 10's of customers who have edited 10's of thousands of pages of content that all relay on the blockquote method of indentation. Now the editor doesn't support it. This is frustrating to no end.

Secondly, your current method is flawed. If I indent and then create a new paragraph, the next paragraph caries on the same indent level. This is great for persisting classes and other formatting options, but unexpected for an indentation.

The example code provided here (http://www.telerik.com/forums/blockquote-for-indent-setting) does not stand up to testing either. If the blockquotes are in a div or table cell, then the HTML gets jammed; not to mention that the example code adds the style AND the blockquote element.

It would have been awesome if you had given us an option (e.g. the newline settings).

Upload warnings are javascript alerts

Can the upload warnings be configured to display as a radwindow?

The FileExplorer has a windowmanager, why shouldn't any warnings be displayed as javascript alerts. (ie: File Exists, File Size/Extension)

Restrict upload to 5 files at a time

I would like to restrict the number of a files that can be uploaded at a time to 5.

I reviewed this posting and applied this code:
http://www.telerik.com/forums/limit-number-of-files-to-be-uploaded

rfeExplorer.Upload.MaxFileInputsCount = 5

But the upload modal allows an unlimited number of files to be selected.

Master/Detail TileList events not fired

Currently we would like to use the RadTileList in a Master/Detail situation. This means that dependent upon the selected tile in the master-tilelist, the detail-tilelist is rendered.

This application scenario works rather well, but fails in the following situation:
1. Open page
-- Ensure nothing is selected and only master items are visible.

2. Click/select a master item, e..g A
-- Ensure that after postback "A" is selected and no detail item is selected.

3. Click/select a detail item, e.g. 2
-- Ensure that after postback "2" is selected

4. Click/select another master item, e.g. B
-- Ensure that after postback "B" is selected and no detail item is selected.

5. Click/select a detail item, e.g. "4"
-- Ensure that after postback "4" is selected <-- BUG, event of TileClick/Selectionchange is not firing and thus is the selection not persisted.

To reproduce this, I've created a new Telerik Web Application (which I cannot currently attach?).

This new web application contains the following implementation of Default.aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<head runat="server">

<title></title>

<telerik:RadStyleSheetManager id="RadStyleSheetManager1" runat="server" />

</head>

<body>

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

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

</Scripts>

</telerik:RadScriptManager>

<script type="text/javascript">

//Put your JavaScript code here.

</script>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

</telerik:RadAjaxManager>

<div>

<telerik:RadTileList runat="server" ID="tlMaster" AutoPostBack="true" DataSourceID="ldsMaster" SelectionMode="Single" OnTileClick="tlMaster_TileClick" OnSelectionChanged="tlMaster_SelectionChanged">

<DataBindings>

<CommonTileBinding TileType="RadContentTemplateTile" Shape="Square" DataNameField="Name" />

<ContentTemplateTileBinding>

<ContentTemplate>

<%#DataBinder.Eval(Container.DataItem, "Description")%>

</ContentTemplate>

</ContentTemplateTileBinding>

</DataBindings>

</telerik:RadTileList>

<asp:LinqDataSource runat="server" ID="ldsMaster" OnSelecting="ldsMaster_Selecting"></asp:LinqDataSource>

<div>

<telerik:RadTileList runat="server" ID="tlDetail" AutoPostBack="true" DataSourceID="ldsDetail" SelectionMode="Single" OnTileClick="tlDetail_TileClick">

<ContentTemplateTileBinding>

<ContentTemplate>

<%#DataBinder.Eval(Container.DataItem, "Description")%>

</ContentTemplate>

</ContentTemplateTileBinding>

</telerik:RadTileList>

<asp:LinqDataSource runat="server" ID="ldsDetail" OnSelecting="ldsDetail_Selecting"></asp:LinqDataSource>

</div>

</form>

</body>

</html>

And the following implementation of Default.aspx.cs:

using System;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.Data;

using System.Configuration;

using System.Web.Security;

using System.Web.UI.WebControls.WebParts;

using System.Web.UI.HtmlControls;

using Telerik.Web.UI;

using System.Collections.Generic;

using System.Linq;

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

{

protected void Page_Load(object sender, EventArgs e)

{

/* Test case to reproduce issue:

* 1. Open default.aspx

* 2. Click/select a master item, e.g. "A"

* 3. Click/select a detail item, e.g. "2"

* 4. Click/select another master item, e.g. "B"

* -- Currently no detail item is selected. That's good.

* 5. Click/select a detail item, e.g. "4"

* BUG: Click/Select event is not fired and thus is the selection not persisted.

*/

if (!Page.IsPostBack)

{

this.tlMaster.DataBind();

}

protected void tlMaster_TileClick(object sender, TileListEventArgs e)

{

foreach (var tile in this.tlMaster.GetSelectedTiles())

{

tile.Selected = false;

}

e.Tile.Selected = true;

this.tlDetail.DataBind();

}

protected void tlMaster_SelectionChanged(object sender, TileListDataEventArgs e)

{

this.tlDetail.DataBind();

}

protected void ldsMaster_Selecting(object sender, LinqDataSourceSelectEventArgs e)

{

e.Result = new List<MasterData>

{

new MasterData("A", "A"),

new MasterData("B", "B"),

new MasterData("C", "C")

}

protected void tlDetail_TileClick(object sender, TileListEventArgs e)

{

foreach (var tile in this.tlDetail.GetSelectedTiles())

{

tile.Selected = false;

e.Tile.Selected = true;

if (selectedTiles.Any())

{

var data = new List<DetailData>

{

new DetailData("A", "1", "1"),

new DetailData("A", "2", "2"),

new DetailData("A", "3", "3"),

new DetailData("A", "4", "4"),

new DetailData("A", "5", "5"),

new DetailData("B", "1", "1"),

new DetailData("C", "2", "2"),

new DetailData("C", "3", "3"),

new DetailData("C", "4", "4"),

new DetailData("C", "5", "5")

};

var selectedTile = selectedTiles.Single();

e.Result = data

.Where(dd => dd.Master == selectedTile.Name);

}

else

{

e.Result = Enumerable.Empty<DetailData>();

}

private class MasterData

{

public string Name { get; private set; }

public string Description { get; private set; }

private MasterData() { }

public MasterData(string name, string description)

{

this.Name = name;

this.Description = description;

}

private class DetailData

{

public string Master { get; private set; }

public string Name { get; private set; }

public string Description { get; private set; }

private DetailData() { }

public DetailData(string masterName, string name, string description)

{

this.Master = masterName;

this.Name = name;

this.Description = description;

}

I hope you are able to identify why the event is not triggered. One thing that I already noted is that the control id differs before and after the postback (view attached files ctrl_id_before_postback and ctrl_id_after_postback): This might have to do something with the issue.

Grid filtering with WepApi datasource

Hi,

I'm trying to implement grid filtering where my Data Sources is webapi.

I tried to follow the following: Take a Walk on the Client Side with WebAPI and WebForms – Part 2

The grid is working fine but I'm I having an issue when I'm trying to implement filtering, there is no GetNextPage() in the request in my ApiController

My project is an ASP.NET web forms project, .net 4.5

Here is my ApiController code:

[HttpGet]

public PageResult<SecuHostUser> Load_Users(ODataQueryOptions<SecuHostUser> options)

{

var context = new ApplicationDbContext();

var users= context.Users.AsQueryable();

var results = options.ApplyTo(users);

return new PageResult<SecuHostUser>(results as IEnumerable<SecuHostUser>, Request.GetNextPageLink(), users.ToList().Count);

}

Client Side Scripting

Hi,

I was trying to use the client side script for image gallery set to work as light, I have couple of queries.

1. I have added a client script for OnImageLoaded, the script is not getting executed when the light box load the image on user click on the thumbnail.

<telerik:RadImageGallery ID="RadImageGallery1" runat="server" AllowPaging="true"
DisplayAreaMode="LightBox" ImagesFolderPath="~\Images"
Skin="Glow" >
<ClientSettings>
<ClientEvents
OnImageLoaded="imageLoaded" />
</ClientSettings>
</telerik:RadImageGallery>

function imageLoaded(sender, args) {
alert("ImageLoaded");
// var imageItem = args.get_item(); }

2. Can we add controls to the light box inside the image gallery similar to the AsyncUpload and get the value in the back end using GetFieldValue.

Thank you.

Regards,
Majid
