How to disable Delete, Remane, and New Folder in FileExplorer

I posted to the treeView forum because I cannot find an area to post questions for the FileExplorer control.

I need to be able to remove the Disable, Rename, and New folder options in the FileExplorer control (or hide that menu all together). I pretty much need it read only. My only exception is I need users to be able to download the files. About a month ago, one of your programmers was able to supply me with the script to download the files upon clicking them so that is taken care of. Below is the existing code:

<%

@ Page Title="" Language="C#" MasterPageFile="~/Employee_MasterPage.master" AutoEventWireup="true" CodeFile="Forms.aspx.cs" Inherits="Secure_Employee_Login_Office_Staff_Area_Forms" %>

<%

@ Register assembly="Telerik.Web.UI" namespace="Telerik.Web.UI" tagprefix="telerik" %>

<

asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server">

Hierarchical Grid Update Problem

HI,

i am using Hierarchical grid with custum filtering.
the problem i am facing is something like this:

when i filter something in the grid and server returns the results the grid is not re-painted properly with the search results although the results returned are correct. when i use rebind method then in that case it paints the results properly but then the drill down button is throwing problem i.e.
"Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. "

please tell me how to get out of this hassle. i have seen all the example given on your web site but could not find anything related to my scenrio.

here is the code for the code behind:

public partial class BookRunOffBank : ViewPage

{

public AjaxOptions options = new AjaxOptions();

protected void Page_Load(object sender, EventArgs e)

{

options.UpdateTargetId =

"page";

RadGrid1.PagerStyle.Position =

GridPagerPosition.TopAndBottom;

RadGrid1.MasterTableView.DataSource = ViewData[

"Companies"];

//////
//if i remove this method then drill down works but filter results are not painted...
//////
if (this.IsPostBack)

RadGrid1.Rebind();

}

protected void RadGrid1_DetailTableDataBind(object source, Telerik.Web.UI.GridDetailTableDataBindEventArgs e)

{

GridDataItem dataItem = (GridDataItem)e.DetailTableView.ParentItem;

e.DetailTableView.DataSource = ViewData[

"CompanyBookRunOff"];

}

}

looking for your reply very soon.

thanks.

Spellcheck not working

Hi there guys.
I've been trying to put to work the Rad Editor with a custom dictionary. It works pretty well until I fire the spellcheking function.
I mean the page loads, but when I try to start the spellcheck process it shows an alert displaying something about not seting the dictionary path.
I've trying setting the property with the Dictionary tags but still doesn't work.
Here's the code:

    
            <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="OnData.Telerik.Samples.Web.Default" %>

Hi iam trying to find out if grid is in edit mode on a button click which is out side the grid.

The isItemInserted() property is working fine which tells me it he grid is in insert mode but the datagridrow.ItemType always returns an error saying undefined, following the code, Please tell me if iam doing any mistake.

var grid=$find("<%=rgSynonym.ClientID%>");
var flag = false;

var rowCount = grid.get_masterTableView().get_dataItems().length;
 var dataItems = grid.get_masterTableView().get_dataItems()
 alert(grid.get_masterTableView().get_isItemInserted());
 if (grid.get_masterTableView().get_isItemInserted()) {
 flag = true;
 }
 for (var i = 0; i < rowCount; i++) {
 var row = dataItems[i].get_element();

            alert(row.ItemType);
            if (row.ItemType == "EditFormItem") {
                var flag = true;
                alert("grid is in edit mode");
                // Cancel the Event so that command edit mode is maintained
                break
                //your code
            }
        }

if (!flag) {

alert("grid is in regular mode");

}

Setting chart properties

I have an a user control (.ascx) that contains a default RadChart. At runtime, based on a user selection, I want to set the properties of the default chart equal to those of a dynamically created chart. If the code sets each property, this appears to work as expected. Is there a simple way to assign all properties (e.g. defaultChart = createdChart)? Or must the properties be looped through and set individually? Examples would be greatly appreciated.

Overriding Chart Skin Series Colour

Hi,

I am trying to set some customised colours to the chart series by using the following code:

baseHourSeries.Appearance.FillStyle.MainColor = System.Drawing.Color.Red;

baseHourSeries.Appearance.FillStyle.SecondColor = System.Drawing.Color.Red;

But it seems that the default colour scheme of the skin I am using is overriding my settings. The strange thing is some colours I set are shown, such as red and yellow, while others like blue or green are hidden away. Is there any flag or property I need to set to make my settings effective?

One more bigger question: It seems that a Chart skin is quite different from the skins of other Telerik controls. How can I disable the built-in skins and create my own customised ones?

Thank you very much for your help.
