[Solved] Server side binding + client side functions

Hello all,

I'm currently working with radgrid component.
Here is a sample of what i am doing :

First, Radgrid binded is done on server side :

IList<VT.LibNHSILdb.EntityFAB> myList = SILDB.FabsList();

GRD_messages.DataSource = myList[0].LST_MESSAGE;

GRD_messages.DataBind();

I get 5500 records from my list and i'm using paging.
But when i clicked on the paging system on my webpage, Radgrid disapeared.

I solved it by handling the postback action on server side :

if(IsPostBack)

{

GRD_messages.DataSource = myList[0].LST_MESSAGE;

GRD_messages.DataBind();

}

Of course, each time i try to page data inside my grid, the binding is done again for EVERY data (I guess, it take a lot of time to do it)

I would like to bind all data in one request on the server (keep the one i'm using), and allow paging on the client side. Is it possible ?
Am i doing correctly my binding ? Is there any improvement i could do to make this faster ? (We're using Nhibernate to acces data)

Many thanks !

Multiple resources availability in relevance with a vacations schedule

Hello,

i' m developing a web application with multiple resources (Employees) using radscheduler. I have 4 tables in my database (one for creatiing employees work schedule, one for connecting employees with their work schedule, one for creating vacations schedule and one for connecting employees with their vacations schedule). So i have 2 radschedulers with multiple resources (one for creating work schedule and one for creating vacations schedule) and 2 database providers (one for each radscheduler). How could i implement when an employee has a vacation for a period of time, this employee will not be available as a resource to work radscheduler for this specific period of time (please note that i' m using recurrence rules)?

Thank you very much.

Destroy the window object on close

Hi

I have a radWindowManager i am using in a UserControl that opens another UserControl in the radWindowManager.

I am using the VisibleOnPageLoad property to set the window to visible on a button click. Now when i close the window it just becomes invisble. When i open it again using the button click the old values inside the window are preserved. However on each click the window should load fresh.

I tried to use the window.radWindow via javascript but it doesnt work and get an error about property not found.

How can i achieve the above?

Thanks in advance.

[Solved] Changing the background colour of the selected item

Hi

I have been reading this thread:http://www.telerik.com/community/forums/aspnet-ajax/combobox/combo-box-color-picker.aspx

As I want to change the background colour of the selected item when an item in my dropdown is selected.
It gives this bit of javascript to do the job, but it's obviously very old as no longer works in the same way.

function onClientSelectedIndexChanged(item)

{

var combo = item.ComboBox;

var comboInput = document.getElementById(combo.InputID);

//here ItemColor is a custom attribute that you can assign in ItemDatabound event

comboInput.style.backgroundColor = item.Attributes.ItemColor;

}

</script>

I have changed it to:

function onClientSelectedIndexChanged(sender, eventArgs) {

var combo = eventArgs.get_item();

var comboInput = document.getElementById(combo.InputID);

//here ItemColor is a custom attribute that you can assign in ItemDatabound event

comboInput.style.backgroundColor = item.Attributes.ItemColor;

}

but the "document.getElementById(combo.InputID); " does not work, as i expected it wouldn't but I don't know what the replacement if it is?

Can anyone help?

NoRecordsTemplate causes Sys.WebForms.PageRequestManagerParserErrorException error

Hello, I have RadGrid uses NoRecordsTemplate, but this template contains server tags as the following:

<

NoRecordsTemplate>

<center>

<iframe src='<%= GetTrainingVideo("RiskManagement.Options") %>' class="EmbededVimeo"

width="400" height="300" frameborder="0">

</iframe

</center>

</NoRecordsTemplate>

if there is no data at page load the template works fine, but when delete the last record the grid rebind itself and generate the following JS error:

Error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.

Details: Error parsing near 'hidden" />

</div>

|0|updatePanel|ctl0'.

This issue just appear when host the application under secure protocol (HTTPS),

I've tried to create the content of NoRecordsTemplate server side at the following event handlers: OnItemCreated and OnPreRender, but the issue still exist.

Do you have resolution for this issue?

Editing Unbound Checkbox in RadGrid

Is it possible to edit unbound checkbox in a radgrid? my experience is telling me no, but perhaps there is trick i could use to do so.

i have a grid bound to a sqldatasource. the data source includes a dummy column cast as a bit to default true. the check box displays checked (as expected) but whenever i enter edit mode, uncheck the box, then click update, the check box reverts to checked because - i surmise - that it is rebinding to the dummy bit column which is set to 1/true.

it is this surmised behavior which i wish to override. is it possibe? if not, would you consider adding a feature to allow for a free standing unbound check box so that developers can present a toggle for subsequent processing of grid items? i do not care to save this information to a data store - i only need it to process selected grid items.

Problem with DefaultButton in Q1 2012

Hi to all,
I have upgraded my telerik controls from 2011.2.915.40 to 2012.1.215.40 with msi installer.
After uprade I discovered that defaultbutton declared for asp:Panel does not fire postback on pressing
the key Enter.
Here is small example. It works fine with older Telerik.Web.UI, but not with Q1 2012.

<%@ Page Language="C#" AutoEventWireup="True" CodeBehind="Default.aspx.cs" Inherits="Test._Default" %>

<!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>Test</title>

</head>

<body>

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

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

<asp:Panel ID="pnlWrapper" runat="server" DefaultButton="btnSearch">

<telerik:RadTextBox ID="tbSearch" runat="server" EmptyMessage="Search" Width="130" />

<telerik:RadButton ID="btnSearch" ButtonType="StandardButton" Text="Search" ToolTip="Searching" runat="server" OnClick="btnSearch_Click" />

</asp:Panel>

<asp:Label ID="lblMsg" runat="server" />

</form>

</body>

</html>

using System;

namespace Test

{

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

{

protected void Page_Load(object sender, EventArgs e)

{

lblMsg.Text = string.Empty;

}

protected void btnSearch_Click(object sender, EventArgs e)

{

lblMsg.Text = "O.K. - Button fired";

}

Does anybody know where is the problem?
Thanks
-Marian
