Questions on UI for ASP.NET AJAX Forum

I have a Tree View that controls a Left Navigation which is bound to a database. My database table has the following columns...

NodeID
NodeTxt
NodeURL
NodeVal
NodeParentID
NodeOrder

I added the NodeOrder column because I'm trying to figure how to allow drag/drop reordering of nodes and save the position of the nodes server-side in the database. I've looked at the example in the demos and it shows how to achieve this client side...event though I don't believe the positions are actually stored to a database or anything.

Do you have any examples of how this can be implemented server side so that the ordering of the nodes can be set and retrieved from a database when dragging and dropping child nodes?

Thanks =)

Problem with radalert

I'm trying to build an alert into my master page that can be accessed from anywhere in the UI code-behind. Any method, any function.

I was doing quite well (I think) but I'm stuck now.

Master page

<%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Default.Master.cs" Inherits="Web.App_Templates.Default.Default" %>

<%@ Register Assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" Namespace="System.Web.UI" TagPrefix="asp" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">

<html>

<head id="Head" runat="server">

<title><%= Page.Title %></title

</head>

<body>

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

<telerik:RadScriptManager

ID="ScriptManager"

runat="server">

</telerik:RadScriptManager>

<telerik:RadAjaxManager

ID="TelerikAjaxManager"

runat="server">

</telerik:RadAjaxManager>

<telerik:RadWindowManager

ID="TelerikWindowManager"

runat="server">

<Windows>

<telerik:RadWindow

ID="TelerikWindow"

runat="server">

</telerik:RadWindow>

</Windows>

</telerik:RadWindowManager>

<asp:UpdatePanel

ID="UpdatePanel"

runat="server">

<ContentTemplate>

<asp:Literal

ID="Feedback"

runat="server"

Text=" " />

<asp:ContentPlaceHolder

ID="MainContentPlaceHolder"

runat="server">

</asp:ContentPlaceHolder>

</ContentTemplate>

</asp:UpdatePanel>

</form>

</body>

</html>

Master page code behind

namespace Web.App_Templates.Default

{

using System;

public partial class Default : System.Web.UI.MasterPage

{

public void ShowFeedback(string feedBackText, bool useAlert)

{

if (useAlert)

{

string radalertscript = string.Format(

"<script language='javascript'>function f(){{radalert('{0}', 330, 210);Sys.Application.remove_load(f);}};Sys.Application.add_load(f);</script>"

, feedBackText);

Page.ClientScript.RegisterStartupScript(this.GetType(), "radalert", radalertscript);

}

else

{

this.Feedback.Text = feedBackText;

}

Web content page

<%@ Page Title="Welcome" Language="C#" MasterPageFile="~/App_Templates/Default/Default.Master" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="Web.Default" %>

<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<%@ MasterType VirtualPath="~/App_Templates/Default/Default.Master" %>

<asp:Content ID="MainContent" ContentPlaceHolderID="MainContentPlaceHolder" runat="server">

<asp:Button

ID="TestFeedbackAlert"

runat="server"

Text="Click Me"

OnClick="TestFeedbackAlert_Click"

Width="100" />

-

<asp:Button

ID="TestFeedbackNoAlert"

runat="server"

Text="Click Me"

OnClick="TestFeedbackNoAlert_Click"

Width="100" />

</asp:Content>

And the code behind

namespace Web

{

using System;

using System.Web.UI;

public partial class Default : Page

{

protected void Page_Load(object sender, EventArgs e)

{

if (!Page.IsPostBack)

{

//this.Master.ShowFeedback("<p>Hello, AppWorld!</p>", true);

}

protected void TestFeedbackAlert_Click(object sender, EventArgs e)

{

this.Master.ShowFeedback("<p>Clicked!</p>", true);

}

protected void TestFeedbackNoAlert_Click(object sender, EventArgs e)

{

this.Master.ShowFeedback("<p>Clicked!</p>", false);

}

The alert will show if you uncomment out the entry in the page load. It will also work if you click the TestFeedbackNoAlert button.

It will not work if you click the TestFeedbackAlert button.

I've looked at the suggestions at:
http://www.telerik.com/support/kb/aspnet-ajax/window/calling-radalert-from-codebehind.aspx

But I'm none the wiser. Can anyone help? I need it to work no matter where it gets called (page load, postback, ajax call, etc.)

Regards,
Richard

[Solved] Node Security

I have a scenario I'd like to know if you can help me with...

I want to populate a TreeView using a Linq data source. This is because there is going to be another page that graphically allows admins to add/edit/delete/re-order nodes. When the admins work with this page, they will obviously be able to see all the nodes.

Now on the actual page that the TreeView is going to be available to the general public, I want to be able to programatically limit which nodes are visible to the user based on active directory groups. Is there a way to turn nodes visible/hidden after the dataset has been returned from the Linq query? How would I accomplish this?

Thanks for the assistance!

"Google suggest" style filtering

Hi all!

I find two links

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/filteringcombo/defaultcs.aspx

http://www.telerik.com/support/kb/aspnet-ajax/grid/google-suggest-style-filtering-in-radgrid.aspx
(sorry! The Hyperlink Manager's problem so I pasted as the text)

They show the way to use the Radcombobox as the filter of RadGrid, the same way with "Google suggest" now
It's one of the best wonderful support from RadCombobox, a good helpful tool for filtering.
But it's so slow when the RadCombobox has lots of data such as 4,000. Is there any ways to improve this one?

Thanks!

Andy.

Export to Excel updates but no save as..

I am setting up a radgrid to export the grid to excel via a button click. It is processing the request. Hiding the columns I don't want to be exported and updating the grid with a new view. It does not have a give me the option to save a file.

<telerik:RadGrid ID="DisplayDataGrid" runat="server" AutoGenerateColumns="False"

AllowSorting="True" AllowPaging="True" PageSize="6" OnNeedDataSource="Grid_NeedDataSource"

OnItemCreated="Grid_ItemCreated" Width="100%" GridLines="None" Skin="Hay" ShowStatusBar="true"

ItemStyle-Font-Size="7pt" AlternatingItemStyle-Font-Size="7pt">

</ClientSettings>

<ExportSettings IgnorePaging="true" OpenInNewWindow="true" FileName="SeismicPetroWeb2D"

ExportOnlyData="true" Excel-Format="ExcelML" Excel-FileExtension="xls" />

<telerik:GridHyperLinkColumn DataTextField="SURVEY" HeaderText="Survey" SortExpression="SURVEY"

UniqueName="SURVEY">

</telerik:GridHyperLinkColumn>
...
...

</telerik:GridHyperLinkColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

and the button click event:

Protected Sub ButtonExcel_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ButtonExcel.Click

DisplayDataGrid.MasterTableView.Columns(0).Visible = False

DisplayDataGrid.MasterTableView.Columns(1).Visible = False

DisplayDataGrid.MasterTableView.ExportToExcel()

End Sub

Thoughts?

Thanks!

Is there a way to persist the initial CurrentFilterFunction?

In our web app, we are setting CurrentFilterFunction values for each column that will be able to be filtered.

However, once one column has some criteria entered in and the user presses <Enter>, that column's filter is properly applied but every remaining column now has a CurrentFilterFunction of "NoFilter"...even after the original criteria is blanked out, essentially setting the grid back to its original state.

Is this something that can be done via the markup/client-side only or are we going to have to set CurrentFilterFunction for each column after every postback?

Or, is there some other method for setting filtering options that persist after postbacks for a page? In our case, we want only one filtering option to be available for each column and no filter icon to be shown.

Thanks.

EntityDataSource updating with RadGrid.

I had a similiar question but I didnt see an answer so...

I am updating a Org item... but I need to updated the 'updatedby' and 'updateddate' which I must do programmatically since it is not part of the radgrid... How do I do this ?

Here is how I am trying to do it but the break point is not being hit.. is this the right way to get my custom update? I suppose I COULD create a seperate stored procedure.. but it would be nice if I could keep it in the entities world.

<asp:EntityDataSource ID="EntityDataSource1" runat="server" ConnectionString="name=G3TEntities"

DefaultContainerName="G3TEntities" EnableFlattening="False" EnableInsert="True"

EntitySetName="Orgs" EnableUpdate="True" OnUpdated="EntityDataSource1_Updated">

</asp:EntityDataSource>

protected void EntityDataSource1_Updated(object sender, EntityDataSourceChangedEventArgs e)

{

Org oOrg = new Org();

oOrg = (Org)e.Entity;

oOrg.updateby = 69;

}
