Hi,

I was trying to get ExcelML based export working. I was able to achieve some formatting and other Goals using ExcelML but as for ExcelML based export we need to implement Advanced databinding using NeedDataSource event, I had to do some changes to my existing code - which i did.
The problem I am facing now after doing all the changes is:

Page data source is changing as per requirement but page is not showing changed data. It's staying one step back. Here is scenario:

1. Page has a drop down with 3 types, suppose A, B and C.
2. First time page shows data depending upon the selection which is A.
3. I change selection to B. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded (as stated by Telerik). Page is still showing data shown previously i.e. data for type A.
4. I change selection to C. Page posts back, datatable is re-built and Grid's dataSource is Set to it but not ReBinded. Now page shows data for type B - which was selected in step 3.
5. If you keep changing the selection. Page shows data for previous type i.e. one step previous. Please note that datasource is built and set properly but page's view is not updated.

I tried rebinding the Grid and it some times works properly but it crashes other times. what to do? Any help?

Thanks.

Get RadComboBox Attribute in RadGrid

Hi

I have a RadComboBox in RadGrid.

How do I get the Attribute of the RadCombo box. I have tired the following code but I get an error :

Protected Sub rcbPortList_Grid_SelectedIndexChanged(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadComboBoxSelectedIndexChangedEventArgs)

Dim rcbPortList_Grid As RadComboBox = New RadComboBox

Massive Data with Multi Columns and LoadOnDemand

Hi Telerik Team,

I'm using the ComboBox with Multi Columns using the OnItemsRequested event and LoadOnDemand.

However my datatable is about 100K records. How can I handle this in RadComboBox?
It is giving me error: "Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property."

The idea is I do not want to change the maxJsonLength property. I want the ComboBox to load only the items requested and not all the data once with the EnableVirtualScrolling property enabled.

Please do let me know how can I achieve such scenario.

P.S.: I do not want to go with RadGrid inside the RadComboBox.

Thanks,
Bilal

RadProgressArea shows only elapsed time

Using your simple example "Monitoring Custom Progress" does not update anything but elapsed time.
http://demos.telerik.com/aspnet-ajax/upload/examples/customprogress/defaultcs.aspx

However, the codebehind runs and when completed the progress UI disappear as expected.
Changing the Culture sometimes makes the progress UI show the complete progress.
Stopping the debug and rerun the same code will not show progress.

My current Culture is da-DK, changing the page culture to en-US does not do the trick though.

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Upload2.aspx.cs" Inherits="PackageManagement.Pages.Common.Upload2" UICulture="en" Culture="en-US" %>

Please advise. My code:

<%@ Page Title="" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Upload2.aspx.cs" Inherits="PackageManagement.Pages.Common.Upload2" UICulture="en" Culture="en-US" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="Content" runat="server">

<asp:button ID="buttonSubmit" runat="server" Text="Submit" OnClick="buttonSubmit_Click" CssClass="RadUploadButton" />

<telerik:RadProgressManager id="Radprogressmanager1" runat="server" />

<telerik:RadProgressArea id="RadProgressArea1" runat="server"

Culture="en-US" DisplayCancelButton="True" HeaderText="Uploading files" />

<br /><br /><br /><br /><br /><br />

</asp:Content>

<asp:Content ID="Content3" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">

</asp:Content>

Codebehind:

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web;

using System.Web.UI;

using System.Web.UI.WebControls;

using Telerik.Web.UI;

using Telerik.Web.UI.Upload;

RadProgressArea1.ProgressIndicators &= ~ProgressIndicators.SelectedFilesCount;

//RadProgressArea1.Culture = System.Globalization.CultureInfo.CurrentCulture;

//RadProgressArea1.Culture = new System.Globalization.CultureInfo("da");

}

RadProgressArea1.Localization.Uploaded = "Total Progress";

RadProgressArea1.Localization.UploadedFiles = "Progress";

RadProgressArea1.Localization.CurrentFileName = "Custom progress in action: ";

}

protected void buttonSubmit_Click(object sender, System.EventArgs e)

{

UpdateProgressContext();

}

private void UpdateProgressContext()

{

const int total = 100;

RadProgressContext progress = RadProgressContext.Current;

progress.Speed = "N/A";

for (int i = 0; i < total; i++)

{

progress.PrimaryTotal = 1;

progress.PrimaryValue = 1;

progress.PrimaryPercent = 100;

Javascript failure: Uncaught TypeError: Cannot read property 'id' of undefined

Hi

I just started a new project were ASP.NET Ajax Teleriks components are used.
We use a RadGrid to present the result of a db search and a simple ASP.NET Button ctrl to submit the search. This button is, as I understand it, ajaxified:

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server" OnAjaxRequest="RadAjaxManager1_AjaxRequest"
DefaultLoadingPanelID="RadAjaxLoadingPanel1">
<AjaxSettings>
<telerik:AjaxSetting AjaxControlID="buttonSearch">
<UpdatedControls>
<telerik:AjaxUpdatedControl ControlID="rgCustomers" />
</UpdatedControls>
</telerik:AjaxSetting>
....

rgCustomers is the ID of the RadGrid ctrl.

When this button is pressed on error occurs:
Uncaught TypeError: Cannot read property 'id' of undefined
The callstack is:

Telerik.Web.UI.RadAjaxControl._initializeRequestScriptResource.axd:107
Type$callBaseMethodScriptResource.axd:1261
Telerik.Web.UI.RadAjaxManager._initializeRequestScriptResource.axd:662
$type.createDelegateScriptResource.axd:628
$type.getHandlerScriptResource.axd:4338
Observer$raiseEventScriptResource.axd:2685
PageRequestManager$_onFormSubmitScriptResource.axd:1355
PageRequestManager$_doPostBackScriptResource.axd:911
$type.createDelegateScriptResource.axd:628
WebForm_DoPostBackWithOptionsWebResource.axd:42
PageRequestManager$_doPostBackWithOptionsScriptResource.axd:916
$type.createDelegateScriptResource.axd:628
(anonymous function)Customers.aspx:1217
onclick

and the RadGrid is not updated dispite that AjaxRequest event fired, an updated datasource was set and DataBind() method of the RadGrid ctrl was called.

I should say that everything works if you tab to the button and then press enter. And after this even mouse clicks works.
Problem seem to occur using all browsers (IE,FF,chrome)

Any ideas?

Thanks
