Hello!

I have again, a problem with the RadListView Control. This time, it looks pretty simple but i don't understand why id doesn't work.
So, to be short this is the problem:

I have a Radlistview, and in the ItemTemplate, i have all sort of things, labels, updatePanels, tables, etc. The RadListView works fine, but when i try to acces ANY element inside using

Dim Label1 as New Label = DirectCast(RadListView1.FindControl("LabelID_Here"), Label)

I get Label as Nothing, or any other elements for that matter. Trust me i have tried different ways to access the controls but none succeeded(I also tried TryCast, and other methods suggested on the web).
The problem is that i try to update a panel wich is inside the RadListView, and i can't find it. From what i have seen the FindControl Method only works on RadListView related events such as ItemDataBound, preRender and so on. The problem is that i need the panel to update every 10 seconds or so, so this is unacceptable.

What is the solution to accessing different controls inside the RadListView ?

Thank you,

and hope for a quick reply,

Tudorel.

RadRotator Not working On Chrome & Firefox

I posted this in an older thread but wanted to start a new one so I can mark as answer and talk about the version etc.

I am using the rotator in IE 8.0.7600, Chrome 4.1.249, FireFox 3.5.7.

Not doing anything odd, using Visual Studio 2008 and my rotator is in a MasterPage.

Here is the rotator:

    
                        <telerik:RadRotator     
        
                            ID="RadRotator1"     
        
                            runat="server"   
        
                            DataSourceID="xmlDataSource1" RotatorType="SlideShow" ScrollDuration="1000"   
        
                            Width="700px" ItemWidth="700px" ItemHeight="168px" Height="168px">    
        
                            <SlideShowAnimation Duration="3000" Type="CrossFade" />   
        
                            <ItemTemplate>   
        
                               <img src="\\lancpa-iis1\Images\rotator\<%# XPath("Image") %>" alt="RFIImage"/>     
        
                            </ItemTemplate>   
        
                        </telerik:RadRotator>   
        
                        <asp:XmlDataSource ID="xmlDataSource1"     
        
                            XPath=""   
        
                            runat="server"     
        
                            DataFile="RotatorImages.xml">    
        
                        </asp:XmlDataSource>

Would like to get this fixed as soon as possible. I know my FireFox and Chrome are a little outdated so going to run those updates to see if anything changes but I figured it would work in older versions anyways.

Thank You,

Coty

[Solved] Losing column viewstate after postback

Hi,

I have a case where I don't know which columns that should be generated for a grid until I am in NeedDataSource.
Then I tried to add the columns in that event. I would really like to use the built in EnableColumnViewState since that simplifies a lot, but the problem is that some (most?) properties are lost on postback, for example the HeaderText of the column in the following sample:

<%@ Page Language="vb" AutoEventWireup="false" CodeBehind="WebForm1.aspx.vb" Inherits="WebApplication4.WebForm1" %>

<!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>

<script runat="server">

Sub rg_NeedDataSource(ByVal sender As Object, ByVal e As Telerik.Web.UI.GridNeedDataSourceEventArgs) Handles rg.NeedDataSource

rg.Columns.Clear()

Dim col As New Telerik.Web.UI.GridBoundColumn()

col.DataField = "Col2"

col.HeaderText = "My header text"

rg.Columns.Add(col)

Dim dt As New System.Data.DataTable()

dt.Columns.Add("Col1", GetType(String))

dt.Columns.Add("Col2", GetType(String))

For i As Integer = 0 To 10

dt.Rows.Add({"Row" & i, "Data"})

Next

rg.DataSource = dt

End Sub

</script>

</head>

<body>

<form id="form1" runat="server">

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

</asp:ScriptManager>

<div>

<telerik:RadGrid ID="rg" runat="server" AutoGenerateColumns="false">

</telerik:RadGrid>

<asp:Button ID="aaa" runat="server" Text="Postback" />

</div>

</form>

</body>

</html>

From what I can see in your source code it should work, but it doesn't, or am I missing something?

Regards
Caesar

CSS Validation

Hi, I've searched for the validation term and i'm finding nothing in the results. Is the slider css valid? I'm using a default skin and it will not validate using the w3c validation page, I'm xhtml valid but would like to add the css validation.

This is a Sitefinity based site that I've just uploaded a couple of weeks back, although I do also have the Premium collection independently, the url if a Telerik member of staff would like to use the w3c validation service is at http://www.oaksoft.co.uk to view the results, the errors are virtually all linked to the radslider, I believe,

thanks for any assistance you can give,
regards,
John C.

P.S. Please forgive the freaky amount of time my site takes to load, asp.net is cycling down and taking around 40 seconds to spool back up, the site is quick thereafter, I'm talking to my hoster re this matter...

RadGrid / GridEditFormType.WebUserControl with Chrome 9

Hi there,

my browser Chrome was automatically updated monday (I think) from version 8 to version 9 (9.0.597.84)
my release is Q3 2010.3.1109.40 / dotnet 4

All my grids edit forms in MasterTableView.EditFormSettingEditFormType = GridEditFormType.WebUserControl became rendering totally crazy .
I mean really really crazy with part of the control appearing/disappearing just moving the mouse over the control
the form control resizes automatically, subcontrols appears/disappears
nothing logical, no ajax call or postback, just crazy client javascript.

Note :
- I tested on two different computer
- Safari & Opera are working normally.
- the edit form control ascx has RadTabStrip & RadTabs and RadFormDecorator is used.
- two skins have been tested (Web20 & Default), same results

does anybody encounter the same issue ?

Create RadPageView via JavaScript

Hello,

I am attempting to create a RadPageView and add it to my MultiPage control via JavaScript.

Everything works server side ,but the problem that I have is when I do post backs, it reloads every control in every page view that I create dynamically.

Example:

public void CreateReport(string reportName)

{

var tab = new RadTab(reportName);

tabReports.Tabs.Add(tab);

var newView = new RadPageView

{

ID = "ReportView" + Guid.NewGuid().ToString().Replace("-", string.Empty)

};

newView.Attributes.Add("ReportTitle", reportName);

multiPage.PageViews.Add(newView);

tab.Selected = true;

newView.Selected = true;

}

Then I have:

protected void multiPage_PageViewCreated(object sender, RadMultiPageEventArgs e)

{

string reportTitle = e.PageView.Attributes["ReportTitle"];

e.PageView.Style.Add("padding", "20px;");

GenerateQuartileReport(reportTitle, e.PageView);

}

protected void cmdViewChart_Click(object sender, EventArgs eventArgs)

{

var button = (RadButton)sender;

CreateReport(button.CommandArgument);

}

I have sevaral rad buttons on my page that will create a new tab with page view when clicked, it will generate a report and display it to the customer. This works great, until I go to do anything that requires a post back, such as creating another report. It reloads all my pages that I created and the sub controls that are on those pages.

I am using the RadAjaxManager so I can get the loading panels and stuff.

I have tried wrapping sections in asp:panels and I still get the same result.

Here is my RadAjaxManager and other bits of code:

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

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadAjaxManager1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadAjaxManager1" />

</UpdatedControls>

</telerik:AjaxSetting>

<telerik:AjaxSetting AjaxControlID="pnlMain">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="tabReports" />

<telerik:AjaxUpdatedControl ControlID="multiPage" />

<telerik:AjaxUpdatedControl ControlID="pnlMain" LoadingPanelID="loadingControl" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

<telerik:RadScriptBlock ID="scriptBlock" runat="server">

<script type="text/javascript">

var tabStrip = null;

function pageLoad() {

tabStrip = $find("<%= tabReports.ClientID%>");

}

function CheckExistingTab(sender, args) {

var tabText = sender.get_commandArgument();

var checkTab = tabStrip.findTabByText(tabText);

if (checkTab) {

sender.set_autoPostBack(false);

checkTab.select();

}

</script>

</telerik:RadScriptBlock>

<telerik:RadAjaxLoadingPanel runat="server" ID="loadingControl" Skin="Black" />

Here are my tabs and multi page:

<telerik:RadTabStrip ID="tabReports" ScrollChildren="true" ScrollButtonsPosition="Middle"

MultiPageID="multiPage" Orientation="HorizontalTop" runat="server" ShowBaseLine="true"

Width="1024">

<Tabs>

<telerik:RadTab Text="Trend Finding Search" Selected="true" />

</Tabs>

</telerik:RadTabStrip>

<telerik:RadMultiPage ID="multiPage" runat="server" CssClass="MultiPageView" OnPageViewCreated="multiPage_PageViewCreated">

<telerik:RadPageView ID="SearchPage" runat="server" Selected="true">

<asp:Panel ID="pnlMain" runat="server">

</asp:Panel>

</telerik:RadPageView>

</telerik:RadMultiPage>

Inside the first page I have several buttons, but here is one as an example:

<telerik:RadButton ID="RadButton1" Image-EnableImageButton="true" CommandArgument="Report Number 1"

runat="server" OnClientClicked="CheckExistingTab"

Height="24px" Width="24px">

<Image ImageUrl="~/App_Themes/Default/Images/chart.png" />

</telerik:RadButton>

<telerik:RadButton ID="RadButton2" Image-EnableImageButton="true" CommandArgument="Report Number 2"

runat="server" OnClientClicked="CheckExistingTab"

Height="24px" Width="24px">

<Image ImageUrl="~/App_Themes/Default/Images/chart.png" />

</telerik:RadButton>

Any thoughts to how I can load my tab/pageview without having to reload all my dynamically created page views when I go to create another one?

I was thinking with JavaScript, but there might be a better solution.

Thoughts?

[Solved] RadWindowManager

I've often wondered why it is that we can have only one RadScriptManager on a page and we can have only one RadAjaxManager on a page but we can have lots of RadWindowManagers on a page.

I have to say that my life would have been easier if I could have just said RadWindowManager.GetCurrent(Page) on more than one occasion.

Just an idle question.

Content is invisible in RadContextMenu

I am using a RadContextMenu and RadGrid in combiation. The RadContextMenu is showing possible actions for a row in the RadGrid. Some of the actions are loading using a WCF service.

After upgrading to .NET 4.0 this has stopped working.

Using Firebug I can see that the RadContextMenu is getting the extra actions from the WCF service and the menu that appears is sized as if there is something to display, but its all blank and nothing happens when I click in it.

I am using VS2010, IIS7, the latest Telerik version, ASP.NET 4.0.

Hope someone can offer some help.

Regards

Thomas

My menu:

<telerik:RadContextMenu ID="rcmLines" runat="server" OnItemClick="rcmLines_ItemClick" >

<Items>

<telerik:RadMenuItem Text="Ignore" Value="I" />

<telerik:RadMenuItem Text="Locate pair" Value="P" />

<telerik:RadMenuItem Text="Set entry account" ExpandMode="WebService" >

</telerik:RadMenuItem>

</Items>

</telerik:RadContextMenu>

The JavaScript invoked from the RadGrid:

function PopLineMenu(sender, eventArgs) {

var menu = $find("<%= rcmLines.ClientID %>");

var evt = eventArgs.get_domEvent();

if (evt.target.tagName == "INPUT" || evt.target.tagName == "A") {

return;

}

var index = eventArgs.get_itemIndexHierarchical();

document.getElementById("lineIndex").value = index;

sender.get_masterTableView().selectItem(sender.get_masterTableView().get_dataItems()[index].get_element(), true);

menu.show(evt);

evt.cancelBubble = true;

evt.returnValue = false;

if (evt.stopPropagation) {

evt.stopPropagation();

evt.preventDefault();

}

The method being called:

[OperationContract]

public RadMenuItemData[] GetEntryAccountMenuItems() {

var list = AppContext.DefaultAccountPlan.NonSumEntryAccounts;

var array = list.ConvertAll(x => new RadMenuItemData {Text = x.NameAndNumber, Value = "Id:"+x.Id}).ToArray();

return array;

}

[Solved] Enter Key causes PostBack in Edit Mode

Hi there,

Is there a way to DISABLE the Enter Key's functionality while in Edit/Insert Mode? I have tried a couple different Java functions and also played with the "AllowKeyboardNavigation" Client Setting on the grid but have had no luck.

Currently the problem only occurs only while in Edit/Insert Mode, and causes Clients to lose information entered in the Edit/Insert Form if they accidentally hit the enter key.

Any Ideas?

Regards,

Landon
