Hi -

I am new to RadControls, and I am having an issue accessing the RadUpload control when it is nested deep inside a RadGrid.

The RadUpload is inside of a RadMultiPage, in the FormTemplate of a RadGrid. I am trying to manipulate the uploaded files, but I can't figure out how to get a reference to the RadUpload when my submit button is clicked. Below is my aspx code for the entire RadGrid:

    
            <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False"  
        
                                    AllowSorting="True" Skin="Black" 
        
                                    AllowPaging="True" PageSize="5" GridLines="None" DataSourceID="SqlDataSource1" 
        
                                    AllowAutomaticDeletes="false" AllowAutomaticInserts="false" AllowAutomaticUpdates="false"  
        
                                    ShowDesignTimeSmartTagMessage="False" ShowGroupPanel="true"> 
        
                                    <PagerStyle Mode="NumericPages" /> 
        
                                    <MasterTableView CellSpacing="-1" DataKeyNames="IDDepartment" DataSourceID="SqlDataSource1" EditMode="EditForms"

RadComboBox postbacks only when losing focus?

Hey All,

I've been searching for a solution to this problem for days now and its starting to get ridiculous. The page I'm building is quite simple. It's got 4 RadComboBoxes, each bound to an ASP SqlDataSource with their SelectCommand set to nothing (SelectCommand=""), except the first one. Once the page loads, the user needs to choose an option from the very first combo box which contains list items only. Once the item is selected, the control posts back and I can then generate the SQL query required to populate the second combo box. Once the user has made his/her selection in the second combo box, the SQL query is build up again for the third combo box and so forth. As mentioned, the first combo box contains list items only and then the 2nd, 3rd and 4th combo boxes contains checkboxes (user must select multiple items from each). Once the combo box (containing the checkboxes) are closed, there is no postback occurring - only when that control has lost focus, then the post back occurs. To the end-user, it seems like the system isn't responding but in the meantime, the Telerik RadComboBox isn't posting back as it should.

At first I thought it might be a setting I've added there that's causing this, but after creating a test page and only the basic settings, the same problem occurs:

ASPX:

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

<%@ 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">

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

<head runat="server">

<title></title>

</head>

<body>

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

<telerik:RadScriptManager ID="ScriptManager1" runat="server"></telerik:RadScriptManager>

<div>

<telerik:RadComboBox ID="cboTest" runat="server" AutoPostBack="true"

CheckBoxes="true" AllowCustomText="false"

onselectedindexchanged="cboTest_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem Text="Item 1" Value="1" />

<telerik:RadComboBoxItem Text="Item 2" Value="2" />

</Items>

</telerik:RadComboBox>

</div>

</form>

</body>

</html>

C#:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

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

{

protected void Page_Load(object sender, EventArgs e)

{

}

protected void cboTest_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)

{

throw new Exception("SelectedIndexChanged");

}

It is quite vital for me to have the combobox post back as soon as its closed (not when it has lost focus). Is there any workaround for this?

Change target folder client side?

Hi,

Is it possible to change the target folder from the client side? I have a combobox with a list of possible folders, and when the selection is changed, I want to change the target folder for the upload.

function OnClientSelectedIndexChanged(sender, eventArgs) {

var item = eventArgs.get_item();

var upload = $find("<%= RadAsyncUpload1.ClientID %>");

upload.TargetPath = ???

alert("You selected " + item.get_text());

}

Alternatively, is it possible to do this on the server side before the files are moved from the temporary directory to the target directory? I can obviously change the value in a postback, but the upload appears to be happening before my event is called.

Any help would be appreciated.

Thanks,
Mathew

RadHtmlChrt for drilling dwon data

Hello Team,

I seek your help and suggestions on "RadHtmlChart" control. We have to use RadHtmlChart to show the drilling down functionality with "Pie" and "bar" charts. I have started using this control but its better to have some suggestions from you guys before finishing it up.

1) I am creating a page where i need to show drilling down of data with pie chart and bar charts. I want to focus on look and feel of the charts. We want the pie charts and bar charts to be good in look and feel, must be flashy and interactive etc. Can you suggest the proper links from where we can refer this kind of charts(for drilling down data).

2) with a good look and feel we want to show some information when user will hover on information , we want the pie's and bars to move and dance. Please help us to find such a good links and demos from where we can refer such type of functionality for RadHtmlChart.

Looking forward for your response.

Thanks and have a great day.!!!

Spell Check Handler Server Error 500 with external Dictionary Path

Hi there,

I'm using the RadEditor for ASP.net from the 2012.1.215.40 Release with SpellChecking enabled in a .Net 4.0 Web Application.

The scenario is that various web servers should use the same dictionaries (especially to share the custom dictionaries).

Everything works fine as long as the dictionary folder resides on the same server. But spell checking fails when it is on a different one.

DictionaryPath is set like "\\server-name\share", same on all systems.

Error Message in Response and EventLog is:

No dictionary loaded. Set the DictionaryPath property from the spell checker settings or copy the dictionaries to ~/App_Data/RadSpell/

The share's security settings are lowered by now to "Everyone" having full access.

Any suggestions on how to set this up correctly or how to find the proper cause for the error?

Kind regards,
Markus
