How to avoid special characters in item request event

Hi,
I have a radcombobox with OnClientKeyPressing event.User should not enter any special characters.How can i block this.I have used "OnClientKeyPressing " for validating for special characters.This is the JavaScript code
function OnClientKeyPressing() {
var evtobj = window.event ? event : e
if ((evtobj.shiftKey) && ((evtobj.keyCode == 188) || (evtobj.keyCode == 190))) {
alert("Special characters not allowed");
evtobj.keyCode = 0;
evtobj.returnValue = false;
return false;
}
}
Eg:-If the user type "vis<" then "<" it should not come.The value should be "vis" instead of "vis<".How can i avoid this.And data should come starting with "vis"

[Solved] Sort Items by Name and Date

I'm working with the RadFileExplorer, and the ViewPath is configured in the C#;

My goal is to sort the items in the RadFileExplorer by name and date, such as

CD 3-1

CD 3-2

CD 3-14

CD 3-18

CD 3-24

Rather than the default behavior of

CD 3-1

CD 3-14

CD 3-18

CD 3-2

CD 3-24

using (SqlConnection connection = new SqlConnection(newConnect))

{

// Create the Command and Parameter objects;

SqlCommand command = new SqlCommand(queryString, connection);

// Open the connection in a try/catch block;

// Create and execute the DataReader;

try

{

connection.Open();

SqlDataReader reader = command.ExecuteReader();

while (reader.Read())

{

UsernameDB = (reader[1]).ToString();

listViewPaths.Add(reader.GetString(3));

listUploadDeletePaths.Add(reader.GetString(4));

WebPageTitle = (reader[5]).ToString();

}

reader.Close();

}

catch (Exception ex)

{

}

RadFileExplorer1.Configuration.ViewPaths = listViewPaths.ToArray();

NodeDrop not firing

I have an orgchart inside of a content place holder for a page with a master page:

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">

<telerik:RadOrgChart ID="RadOrgChart1" runat="server" EnableCollapsing="true" EnableDragAndDrop="true">

</telerik:RadOrgChart>

</asp:Content>

The data I'm using to populate the orgchart is coming from a web service - so on page load I attach the nodedrop event handler, grab the resource data which I then translate into a data table, then I do my data binding:

protected void Page_Load(object sender, EventArgs e)

{

RadOrgChart1.NodeDrop += RadOrgChart1_NodeDrop;

GetResources();

LoadEmployees();

RadOrgChart1.RenderedFields.ItemFields.Add(new Telerik.Web.UI.OrgChartRenderedField() { DataField = "Position" });

RadOrgChart1.DataSource = employees;

RadOrgChart1.DataFieldID = "EmployeeID";

RadOrgChart1.DataFieldParentID = "ReportsTo";

RadOrgChart1.DataTextField = "FullName";

RadOrgChart1.DataImageUrlField = "ImageUrl";

RadOrgChart1.DataBind();

}

The orgchart loads as expected and looks great. When I drag and drop an item and set up break points, the page load events are hit but not the nodedrop events. I'm not sure if there is something special I have to deal with due to the master page or if I'm just missing something basic in the page life cycle. The way I'm looking at this I'm essentially doing it exactly as the demo suggests: http://demos.telerik.com/aspnet-ajax/orgchart/examples/draganddropsimplebinding/defaultcs.aspx

One additional piece of information is that the script manager is located on the master page - not sure why that should cause a problem.

Inserting: KeyValues is empty

Hi and thank you for reading.

When I attempt an insert with the following, it enters the function correctly, but the KeyValues property is always empty and, thus, it never enters the loop over the dictionary from ExtractValuesFromItem. As a result, it inserted a new blank row.
It also may be relevant to mention that this page has two RadGrid instances, including this one, but they're operating on separate data sources with separate scripting. The other RadGrid works fine with similar code, however I'm not allowing inserts on that one.
I would appreciate any advice or suggestions.

RadTreeView Node Refresh

Hi Support
I'm using Telerik Rad Tree View for one of my asp.net application, my requirement is that :

There a Refresh Button in my telerik radpane container .
User click on the nodes of tree view and different pages are open for that .
After they click on refresh button ( note : refresh button click because user can right click on any child node and create new node after that) I want to show user the last node where user was there (means from parent node to child node should remain expanded but other nodes that user did not click should closed, if click then expanded ) before click on refresh button .

How Can I do that , pl any suggestion

RadCompression and Chrome issue

A few weeks ago, I decided to try RadCompression on my website, and followed the instructions here. It seemed to work fine in FireFox (which I use for development), but when we finally got around to cross-browser testing, found that several pages started getting an exception in System.Web.UI.Page.RegisterRequiresControlState(), for example:




[InvalidCastException: Unable to cast object of type 'System.String' to type 'System.Collections.IDictionary'.]
   System.Web.UI.Page.RegisterRequiresControlState(Control control) +104
   System.Web.UI.WebControls.PasswordRecovery.OnInit(EventArgs e) +32
   System.Web.UI.Control.InitRecursive(Control namingContainer) +333
   System.Web.UI.Control.InitRecursive(Control namingContainer) +210
   System.Web.UI.Control.AddedControl(Control control, Int32 index) +198
   System.Web.UI.ControlCollection.Add(Control child) +80
   System.Web.UI.WebControls.Login.CreateChildControls() +175
   System.Web.UI.Control.EnsureChildControls() +87
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +23
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Control.FindControl(String id, Int32 pathOffset) +327
   System.Web.UI.Page.FindControl(String id) +38
   System.Web.UI.Page.ProcessPostData(NameValueCollection postData, Boolean fBeforeLoad) +232
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1743

In debugging the issue, I found that
1. It only seems to affect Chrome browser
2. Removing RadCompression stopped the error
3. Keeping RadCompression but changing the browser controlAdapter from RadSessionPageStateCompression to RadHiddenFieldPageStateCompression stopped the error

Is there any reason why this would happen only in Chrome? Is there something else I need to use RadSessionPageStateCompression?

Thanks for any info

[Edit: I'm using v2011.1.519.35]

Draging a DIV to the TreeView

Hello,

What I will need is this. On the page I have one RadTreeView control, on the same page I can have HTML DIV element. Is it possible, somehow to drag this DIV element to the RadTreeView control and get server side event?

This is very similar, or even identical to functionality you have on FileExplorer / First Look example where you can drag table rows to the tree and move files by doing so.

Thanks!
