I have large amount of data and I’m trying out the example found here: http://demos.telerik.com/clientbinding3/

I managed to get it working with my data and filtering works, but I can’t seem to get it to change the pages. It also doesn’t update the “Time to get data” or “Time to update Grid”.

I’m wondering if it’s not getting the “ClientBindingExample.js”, because if I comment the javascript out of my ASPX file, it still loads the grid fine.

Is there something I could be missing? I’m sure it has to be easy, but I don't see it. :(

Thanks!

Sorting while bound to EntityDataSource

Hello,

While working on a Grid we integrated in one of our pages, I noticed how the sorting was not working properly. When trying to sort, the column gets marked as sorted (either asc or desc), but the actual items in the grid do not get sorted at all, they stay in the exact same order as they were before.

Trying to figure out what the problem was, I seem to have gotten the problem down to its core: the EntityDataSource bound via the RadGrid_NeedDataSource event handler.

Code:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="test.aspx.cs" Inherits="test" MasterPageFile="~/Site.master" Theme="EventDrive" %>

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

<asp:Content ID="BodyContent" runat="server" ContentPlaceHolderID="MainContent">

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

<telerik:RadGrid ID="RadGrid1" OnNeedDataSource="RadGrid_NeedDataSource"

runat="server" AllowPaging="True" AllowSorting="True">

</telerik:RadGrid>

<asp:EntityDataSource ID="edsED" runat="server" ConnectionString="name=EventdriveEntities"

DefaultContainerName="EventdriveEntities" EntitySetName="Person" AutoSort="true" />

</asp:Content>

Code Behind:

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;

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

{

protected void RadGrid_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

edsED.Where = "it.EventID = 2324"; //fetch EventID here.

RadGrid1.DataSource = edsED;

}

Is this a known issue? Is there anything I can do to resolve this problem?

Any help would be more than welcome!

Thanks,

Glenn

RadChart Resizing OnLoad

Hi,

I am trying to resize my chart when the page load. Here is the code I have right now:

JavaScript:

$(document).ready(ResizeChart());

function ResizeChart()

{

var ajaxManager = $find("<%= RadAjaxManager1.ClientID %>");

var arg1 = $(document).width();

var arg2 = 305;

ajaxManager.ajaxRequest(arg1 + "," + arg2);

}

VB:

Protected Sub RadAjaxManager1_AjaxRequest(ByVal sender As Object, ByVal e As Telerik.Web.UI.AjaxRequestEventArgs) Handles RadAjaxManager1.AjaxRequest

Dim argument As String = e.Argument

Dim sArray As String() = argument.Split(",".ToCharArray())

chartLabos.Width = CInt(sArray(0))

chartLabos.Height = CInt(sArray(1))

End Sub

ResizeChart() is called on the onresize event on the Body and it works! But when it's called with the jQuery "$(document).ready" my variable ajaxManager is null, so I understand that the RadAjaxManager is not loaded at this time. How can I call ResizeChart() on the load of the RadChart? I can't find any ClientEvent for the RadChart.

Thanks.

radgrid header shrinked when window resized.

Hi,

I have a radgrid inside a radwindow. And in my case, i need to set the width of the radwindow after the page loads.
Problem with this is, when the radwindow resizes, the grid also resizes. This is all fine except for the grid header.
It appears shrinked to the left and a white gap appears on the right. How do i solve this?

Regards,
Dexter

PS:This only happens in IE

Invalid JSON primitive in EditTemplate

Hi, I'm having a problem with RadListView.
In my EditTemplate i have some validation Controls. When i submit data with invalid fields the validation occurs so everything is ok. The problem is when the fields are all validated and the data is submited. I get an error: Invalid JSON Primitive. Any clue?

Some extra info:
- the ListView is in an UserControl loaded dynamically.
- It works ok without the validation controls.

thanks in advance.

PDF Export Error

Hi,
I am getting the follwing error while exporting PDF file. I used the following formatted text in grid "Workers Compensation Information[binary]" in one of the column.I assume the error mainly comes due to using non unicode character. So i would like to know how to avoid the following error and also how to replace the appropriate character symbols with matching text. Since i am using lot of symbol related characters it would be more helpful to me to track error.

My error message is:

Invalid XHTML. RadGrid has to render correct XHTML in order to export to PDF.
Parse error:
Reference to undeclared entity 'W'. Line 2004, position 75.
at line:
Louisiana Workers' Compensation Notice (B&W; English)[binary]

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

show the combobox typed text part of items in bold

Team

I am using radcombobox in my application.

I am using it to implement search functionality. whenever we type something in combobox the resulting items is getting displayed in the combo list properly

& when result is not there it should display “no result found” & should give a link to a page which is used to add the items in that combobox.This I have added in the list of items .It is working.(attached is the screenshot for this requirement img.)

For this I am using OnItemsRequested event.

I have a requirement to show text of items in bold which I am typing in combobox. (attached is the screenshot for this requirement1 img.)
This feature is working when I set Filter ="Contains" but for displaying “no result found” & should give a link to a page which is used to add the items in that combobox requirement I can’t set this property. If I set this property it won’t show “no result found” & link .

I have tried to set it by tab but it shows tag as it is in item text.

Is there another way to show the combobox typed text part of items in bold?
