Am trying to access a control in the emptydata item template to disable it for certain users. My template looks like this:

<EmptyDataTemplate>

This staff member currently has no blogs.

<br />

<asp:LinkButton ID="lnkBtnAddBlog" runat="server" CommandName="AddBlog"

Visible="<%# AllowUserEdits() %>"> Add new blog</asp:LinkButton>

</EmptyDataTemplate>

The function in the "visible" attribute isn't firing, yet the exact same button is in the Item template and it fires ok there.

I also can't find a FindControl function for the empty item in code..but i can for the other templates.

So how would i go about accessing that control?

Many thanks

Rad Panel Item , Menu and XMLwindow

I have Rad panel Item on left and xml window on right . When anyone clicks on childradpanelitem1 i want that about.htm loads in the xml window.

The Rad panel Items actually contains submenu of the selected main menu . That means when anyone clicks the submenu of my menu the respective file must appear in xml window . That is when he clicks on About Us (main menu) > Contact us (sub menu) the xml window must come loaded with contact.htm .

I want to have 6 aspx files for 6 menus and able to jump from one file to another depending on the submenu cicked . That means i am on Admission.aspx but user clicks on About Us (main menu) > Contact us (sub menu) which is in the file about.aspx and in that also the xml window must come loaded with contact.htm .

imageURL not persisted on postback

Here's my code to make new nodes

function addApproverClick() {

var window = $find("<%= newTabWindow.ClientID %>");

var tree = $find("<%= treeView.ClientID %>");

window.close();

tree.trackChanges();

var node = new Telerik.Web.UI.RadTreeNode();

node.set_text('test');

node.set_value(getPickerOptions());

node.set_imageUrl("../images/person-white.png");

selectedNode.expand();

if (addType == "Add") {

selectedNode.get_parent().get_nodes().add(node);

} else {

selectedNode.get_nodes().add(node);

}

tree.commitChanges();

}

So it all works, great when I click a button on the page to postback, all the nodes created clientside are missing that image.

It seems that it's appending the Host to the beginning of it instead of what I assigned it.

Clicks in the inline edit template bleed through to OnClientTimeSlotClick event

I am using the OnClientTimeSlotClick event to allow users to insert and edit appointments with a single click. But I find that whenever the user clicks inside the insert or edit template, the click event bleeds through to the scheduler and raises the OnClientTimeSlotClick event.

I can kinda work around this by checking to see if an object with the class rsAptEditFormWrapper exists and if it does not open the insert form. But this also prevents a user from cancelling out of the edit by clicking on a blank slot to create a new appointment.

[Solved] ClientSelectColumn

Consider the following grid ...

<telerik:RadGrid ID="RadGrid1"

runat="server"

AutoGenerateColumns="false"

AllowMultiRowSelection="false">

<MasterTableView>

<Columns>

<telerik:GridClientSelectColumn UniqueName="Select"

Visible="true"></telerik:GridClientSelectColumn>

<telerik:GridBoundColumn UniqueName="Name"

DataField="Name"

HeaderText="Name"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Email"

DataField="Email"

HeaderText="Email"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

Running the page with this definition on it displays a grid with a select column. The select column's header has a checkbox in it. This is all good.

Now, consider the case where the above grid should only display the select column under programmer-defined conditions. Also consider that the grid should be limited to single row selection when the select column is not visible.

The following code sets up an example for this ...

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default5.aspx.cs" Inherits="Default5" %>

<!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>

</head>

<body>

<form id="form1"

runat="server">

<telerik:RadScriptManager ID="RadScriptManager1"

runat="server">

</telerik:RadScriptManager>

<telerik:RadGrid ID="RadGrid1"

runat="server"

AutoGenerateColumns="false"

AllowMultiRowSelection="false">

<MasterTableView>

<Columns>

<telerik:GridClientSelectColumn UniqueName="Select"

Visible="true"></telerik:GridClientSelectColumn>

<telerik:GridBoundColumn UniqueName="Name"

DataField="Name"

HeaderText="Name"></telerik:GridBoundColumn>

<telerik:GridBoundColumn UniqueName="Email"

DataField="Email"

HeaderText="Email"></telerik:GridBoundColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<Selecting AllowRowSelect="true"/>

</ClientSettings>

</telerik:RadGrid>

<asp:Button ID="Button1"

runat="server"

Text="Click"

OnClick="Button1_Click"/>

</form>

</body>

</html>

using System.Collections.Generic;

using System;

public class Contact

{

public string Email { get; set; }

public string Name { get; set; }

}

public partial class Default5 : System.Web.UI.Page

{

protected void Button1_Click(object sender, EventArgs e)

{

bool currentValue = RadGrid1.Columns.FindByUniqueName("Select").Visible;

RadGrid1.AllowMultiRowSelection = !currentValue;

RadGrid1.Columns.FindByUniqueName("Select").Visible = !currentValue;

}

protected void Page_Load(object sender, EventArgs e)

{

List<Contact> contacts = new List<Contact>{

new Contact{Name = "Stuart Hemming1", Email = "sejhemming@gmail.com"},

new Contact{Name = "Stuart Hemming2", Email = "sejhemming2@gmail.com"},

new Contact{Name = "Stuart Hemming3", Email = "sejhemming3@gmail.com"},

new Contact{Name = "Stuart Hemming4", Email = "sejhemming4@gmail.com"},

new Contact{Name = "Stuart Hemming5", Email = "sejhemming2@gmail.com"},

new Contact{Name = "Stuart Hemming6", Email = "sejhemming@gmail.com"}

};

RadGrid1.DataSource = contacts;

RadGrid1.DataBind();

}

Run the page and you have a grid with 2 columns and a single button. Click the button to display the select column and to allow multirow selection. When the grid redraws, it does so with the select column displayed but no checkbox appears in the header.

Is this broken, or am I just missing something?

[Solved] A request

'tis a minor thing, but do you think you could reorganise RadGrid | Client-side API | Subscribing to Client Events | Client Events so that the events are listed in alphabetical order?
