RadListBox and SelectedItems

Hi,

I am using a RadListBox and I would like to find if the items that are selected in this list when clicking on a search button. However, when doing the following I have no item selected (the Label text is = 0) and I do not see why?

In my Search.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="Search.ascx.cs" Inherits="Controls.Search.Search" %>

<telerik:RadListBox ID="List1" runat="server" SelectionMode="Multiple" CssClass="rListBx"/>

In my Search.ascx.cs:

Label.Text = List1.SelectedItems.Count().ToString();

My Search_Click function is in a partial class that inherits from System.Web.UI.UserControl

In my Search.ascx.designer.cs

protected global::Telerik.Web.UI.RadListBox List1;

An idea about what I am doing wrong here?

Thanks

Finding out any changes to the RadAsyncUpload control by user or not? (Any file added/updated/deleted)

Hi,
I want to find out changes to the controls on the form if any element is changed but without saving it if the user moves to the other pages I want to show the user to ‘some unsaved changes are there do you want to save it or not?’ something like to show to the user. For archiving this I am using the JavaScript. With this I was able to find out any changes to all the controls on the form except RadAsyncUpload control.
Can you please advise how can I find out the changes to this RadAsyncUpload control using javascript?
Thanks,

AsyncUpload

Geting " no data to display message" even though my datasource has data

So I'm binding the data to the treelist via datatable. It defintely has data (over 2000 rows), and I'm using the needsdatasource event handler to bind. It must be recognizing SOMETHING because after it binds, the column names from the data appear in the list it just show no data. VS 2015 is that makes a difference. Code below:

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

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

{

RadTreeList1.Rebind();

}

protected void btn_Export_Click(object o,EventArgs e)

{

RadTreeList1.ExportSettings.Excel.Format = TreeListExcelFormat.Biff;

RadTreeList1.ExportToExcel();

}

public DataTable GetDataSource()

{

var dt = new DataTable();

var strQuery = "";

strQuery += " select ";

strQuery += " USERID [CustomerID]";

strQuery += ", USERID ";

strQuery += ", FileInput";

strQuery += ", MeterNo ";

strQuery += ", MeterName ";

strQuery += " ,LastReadTime ";

strQuery += " from xx i ";

strQuery += " JOIN xxx u ON u.CustomerID = i.USERID ";

strQuery += " where ConnectionDevice = 18 AND isActive=1";

strQuery += " and u.isParent = 1 ";

strQuery += " AND Time<@Time ";

strQuery += " order by userid,fileinput,meterno";

using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["xxx"].ConnectionString))

{

con.Open();

var cmd = new SqlDataAdapter(strQuery, con);

cmd.SelectCommand.Parameters.AddWithValue("@Time", "11/1/2015");

cmd.Fill(dt);

}

return dt;

}

Like I said it displays the treelist with all the columns from the query and corresponding datatable fine, but it's not displaying any data despite having 2000+records.

Hi,

I need to create a multi-level form for one of my requirements.

I have to create around 8 levels and each level will contain about 15 user fields (fields like textbox,checkbox, dropdown, radio buttons, file upload options so on..)

Will using RadWizard control be apt for my requirements ? and if i use radwizard will there be any performance issue as i will be having more that 100 user fields in a single page. Also, thanks to let me know if there are any other alternative for achieving my requirements.

Thanks in advance for the response.
