Hi Team,

I have a RadGrid with multiple template columns, In one column i have a link and textbox and on another I have a dropdown list.

I click on link, a popup opens select some value and set in the grid's text box, Since I need to bind the dropdown from text based on textbox value, I post back the using the Autopostback=true, But I am not able to bind the combobox, as I am not able to retain the values for textbox.

Can you help me on this.

Regards,

Sandeep

Need help with adding a header to a new radWindow

I'm creating a user control that adds a new window to the RadWindowManager. I'm trying to add a header to the window, which seems easy enough in the demo code, but I'm getting an error that says "'header' is not a member of 'Telerik.Web.UI.RadWindow'.". I'm new to jquery and Ajax controls, so I don't know if I'm missing something.

(Telerik version is 2014.3.1024.45)

ascx file -

<telerik:RadScriptManager runat="server" ID="RadScriptManager1" />

<telerik:RadWindowManager RenderMode="Auto" ID="RadWindowManager1" ShowContentDuringLoad="false" VisibleStatusbar="false" ReloadOnShow="True" runat="server" EnableShadow="true" EnableViewState="False">

<Shortcuts>

<telerik:WindowShortcut CommandName="RestoreAll" Shortcut="Alt+F3"></telerik:WindowShortcut>

<telerik:WindowShortcut CommandName="Tile" Shortcut="Alt+F6"></telerik:WindowShortcut>

<telerik:WindowShortcut CommandName="CloseAll" Shortcut="Esc"></telerik:WindowShortcut>

</Shortcuts>

</telerik:RadWindowManager>

Code Behind -

Public Sub ShowModalDialog(ID As String, URL As String)

Dim newWindow As New RadWindow()

'NavigateUrl to be chosen dynamically.

newWindow.ID = ID

newWindow.NavigateUrl = URL

newWindow.VisibleOnPageLoad = True

newWindow.OnClientClose = "OnClientClose"

newWindow.Modal = True

newWindow.header = "Test"

newWindow.Shortcuts.Add(NewWindowShortcut("Maximize", "Ctrl+F2"))

newWindow.Shortcuts.Add(NewWindowShortcut("Restore", "Ctrl+F3"))

newWindow.Shortcuts.Add(NewWindowShortcut("Minimize", "Ctrl+F8"))

RegisterControl(ID)

ModalWindow.Windows.Add(newWindow)

End Sub

Window

One RadAjaxManager in master page - issues?

Hi,

I am thinking about adding the AjaxManager to the master page instead of one manager for each page.

Is there any disadvantage of using a single RadAjaxManager performance wise? I have a common type for Masterpage so I don't have to use findcontrol.

In the help file,

6) RadAjaxManager and RadAjaxPanel at the same application

There are some known issues when using both the manager and the panel in some complex applications - MasterPage or WebUserControls. However, note that a single RadAjaxManager (and no panels) in the master/main page could handle all the scenarios.

What are the known issues? Since RadAjaxManager cannot ajaxify asp:panel anymore, it is not as easy to use as the RadAjaxPanel. I want to avoid any issues beforehand before I add a RadAjaxManager to my masterpage.

In addition, about RadCodeBlock:

What's the difference between using it and a regular asp:placeholder? If I enclose the <%=%> within a placeholder, it works as well. I need to know the advantage/disadvantage of using either performance wise. Since both are derived from UI.Control and don't have any additional functionalities... And since you don't have any info about it in the help file, I don't really see the point of having this extra control..

Hierarchical grid with varying templates?

My customer wants to display different nested row controls, depending on the several clickable cells in a row. So if the user clicks on the cell in column 1, a dialog allowing to change some data should appear. If the user clicks on the cell in column 2, a different view presenting some child records shall be displayed, etc. etc.

Are NestedView templates the way to go here? Can I replace the template with every postback?

Also, there are views required that concern all rows. Would it be possible to show those before row 0?

Javascript error due to RadSpell

Recently I have upgraded Telerik version(UI for ASP.NET AJAX) of our project to 2016 Q1. I am using RadSpell on a modal window to check spelling of a textbox on a toolbar button click. After checking for spellings, when I am clicking Close button of the parent modal window, a javascript error is occurring.

Unable to get property 'mouseup' of undefined or null reference
URL: http://localhost/iTrakWebApp/ScriptResource.axd?d=9q9IkYzT1P6H219_x_k_x6tLRP323yXAyrwkg1Ad2IPRcVJmSr5AfeHLfQpTT0ru3iT17DNdmYKU5PFr8hBs5AsWwk8jA0vEMVJJ-56Xnq_NSUL51QzqhcizV-kFio5lZ5xjPw2&t=ffffffffcf2f22b2

Note that, this error was not occurring in 2015 Q3 version. Also I can't reproduce the issue if I remove the RadSpell control from the page.

For convenience, I am adding the lines of code related to RadSpell control. It would be of great help if someone can point out why this js error is occurring. Thanks in advance.

<Rad:RadSpell ID="SpellCheck" runat="server" ButtonType="None" OnClientDialogClosed="SpellCheckClosed" IsClientID="true" meta:resourcekey="SpellCheckResource1" />

......

// called this function on spell check button click

function StartCheck() {

var sources = [new Telerik.Web.UI.Spell.HtmlElementTextSource($get('<%=tbxSynopsis.ClientID %>'))];

var spell = $find('<%= SpellCheck.ClientID %>');

spell.set_textSource(new Telerik.Web.UI.Spell.MultipleHtmlElementsSource(sources));

spell.startSpellCheck();

}
