[Solved] what is the correct configuration of RadAjaxManager - this issue is in ralationship with UpdatePanel !

hi dear telerik team

At first look at the below aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="Amlak.WebForm4" %>

<%@ 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">

<asp:ScriptManager ID="ScriptManager1" runat="server">

</asp:ScriptManager>

<div>

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadComboBox1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="CheckBox1" UpdatePanelRenderMode="Inline" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" AppendDataBoundItems="True"

OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">

<Items>

<telerik:RadComboBoxItem runat="server" Text="1" Value="1" />

<telerik:RadComboBoxItem runat="server" Text="2" Value="2" />

<telerik:RadComboBoxItem runat="server" Text="3" Value="3" />

<telerik:RadComboBoxItem runat="server" Text="4" Value="4" />

</Items>

</telerik:RadComboBox>

<br />

<asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged"

Text="Check Me" TextAlign="Left" />

<br />

<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

</div>

</form>

</body>

</html>


My code behind is like this:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
 
namespace Amlak
{
    public partial class WebForm4 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
 
        }
 
        protected void RadComboBox1_SelectedIndexChanged(object sender, Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs e)
        {
            if (RadComboBox1.SelectedItem.Value == "2")
            {
                CheckBox1.Checked = true;
            }
            else
            {
                CheckBox1.Checked = false;
            }
 
        }
 
        protected void CheckBox1_CheckedChanged(object sender, EventArgs e)
        {
            if (CheckBox1.Checked)
            {
                TextBox1.Text = "text";
            }
            else
            {
                TextBox1.Text = "";
            }
        }
    }
}

My goals: 

I want to force RadComboBox1 to work in AJAX mode 
and change the CheckBox1.Checked by defined conditions in code behind. 
-> do not want postback for this.  
I want to force CheckBox1 to work in PostBack mode and change the TextBox1.text by defined conditions in code behind. -> I want postback for this.

In this scenario -> RadComboBox1 works fine

but I don't know why OnCheckedChanged="CheckBox1_CheckedChanged" does not fire when we change check of CheckBox1! (because we added it as update of RadComboBox1 In RadAjaxManager1).



My questions:

1-Should I add RadComboBox1 as update Of RadComboBox1 or not?  However it works fine without adding this.  

2-If we add ChechBox1 To RadAjaxManager1 like below:  
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm4.aspx.cs" Inherits="Amlak.WebForm4" %>
 
<%@ 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">
    <asp:ScriptManager ID="ScriptManager1" runat="server">
    </asp:ScriptManager>
    <div>
        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">
            <AjaxSettings>
                <telerik:AjaxSetting AjaxControlID="RadComboBox1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="CheckBox1" UpdatePanelRenderMode="Inline" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
                <telerik:AjaxSetting AjaxControlID="CheckBox1">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="TextBox1" />
                    </UpdatedControls>
                </telerik:AjaxSetting>
            </AjaxSettings>
        </telerik:RadAjaxManager>
        <telerik:RadComboBox ID="RadComboBox1" runat="server" AutoPostBack="True" AppendDataBoundItems="True"
            OnSelectedIndexChanged="RadComboBox1_SelectedIndexChanged">
            <Items>
                <telerik:RadComboBoxItem runat="server" Text="1" Value="1" />
                <telerik:RadComboBoxItem runat="server" Text="2" Value="2" />
                <telerik:RadComboBoxItem runat="server" Text="3" Value="3" />
                <telerik:RadComboBoxItem runat="server" Text="4" Value="4" />
            </Items>
        </telerik:RadComboBox>
        <br />
        <br />
        <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="True" OnCheckedChanged="CheckBox1_CheckedChanged"
            Text="Check Me" TextAlign="Left" />
        <br />
        <br />
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
    </div>
    </form>
</body>
</html>

So it works fine in AJAX mode, but I want to force CheckBox1 to work in PostBack!

How can I fix this issue? 

3-Should I add TextBox1 as update of RadComboBox1 in RadAjaxManager or not?  

Thanks for attention to my question.
best regards

[Solved] Impossible to launch server-side event on EditorDialogs

Hello

I want to modify the EditorDialogs that I can find here : C:\Program Files\Telerik\RadControls for ASP.NET AJAX Q2 2010\EditorDialogs
Specifically, I need to change the RadFileExplorer1.Configuration.ContentProviderTypeName in the FileBrowser dialog, so that when it looks for a file, it lists them from the database instead of from the file system.

So, I copied the ascx in the EditorDialogs folder of my project. It seems to work, because if I add "aaaa" in the control, for example, it shows in the resulting html.

However, no server side code seems to work, at all, ever, period. If I add server-side code, then add breakpoints, they do not load (can't reach breakpoint, symbols not loaded)
- I tried to add a Page_Load method : nothing happens, not even if I just try a simple "response.write".
- I tried "<%= "test" %>" somewhere in the usercontrol : nothing shows
- I switched the language of the controls to VB (my project is vb.net, but the controls are in c#), still no luck
- I re-created the control using a code-behind file, still nothing, with either vb or c#

So, any idea on how I can switch the ContentProvider of every FileBrowser of every RadEditor of the project ? (and there are a lot of editors in there...)

Thanks

[Solved] Changing the displayed location of the RadColorPicker

I have a RadWindow that is used as a dialog. The page in it has a couple of RadColorPickers in it.

When displayed, the colour pickers are always displayed relative to the picker button which causes scrollbars to appear in the dialog, regardless of the size of the window (See this Jing video for an example).

My mark-up looks something like this ...

<telerik:RadColorPicker id="ColBackColour" runat="server" ShowIcon="true" KeepInScreenBounds="true" ShowEmptyColor="false" AutoPostBack="false" PreviewColor="false" Columns="35">

<telerik:ColorPickerItem title="Light Pink" value="#FFB6C1"/>

</telerik:RadColorPicker >

I note that whatever I do there is always item level CSS injected to set the top and left of the colour picker. I need to be able to override this to set the position relative to the dialog bounds.

Adding AjaxSettings and AjaxLoadingPanel programmatically

Hi,
We have an issue in some code for a user control where we are dynamically building up the controls on the page including the AjaxLoadingPanel and AjaxSettings via the AjaxManager.
We have follow the instructions as per http://www.telerik.com/help/aspnet-ajax/ajax-ajax-manager-programmatic-creation.html and http://www.telerik.com/help/aspnet-ajax/ajax-add-ajaxsettings-programmatically.html and placed the code in the relevant event handlers but the loading panel is not displayed. Also the ClientEvents OnRequestStart/End events don't seem to fire.
We don't have any issues in pages where we have declared the controls in markup.
We are using web parts heavily in our application (a CMS), could this have a bearing on the problem?

Hi,

I have a hierarichal grid and I'm trying to change the parent row cell color. The below code is working fine for changing the background color of a cell. But when I click on the expand arrow it is not expanding the detail table. If I comment out this code, it expands fine.

What am I doing wrong? Suggessions please....

protected void RadGridResults_ItemDataBound(object sender, GridItemEventArgs e)
        {
if (e.Item is GridDataItem)
                    {
                        GridDataItem dataItem = (GridDataItem)e.Item;
                        if (dataItem["rpd_cott_ind"].Text == "COTT")
                        {
                            dataItem["rpd_cott_ind"].BackColor = System.Drawing.Color.Brown;
                            dataItem["rpd_cott_ind"].Font.Bold = true;
                        }
                    }
}
