RadGrid Stuck in Edit Mode - Entity Framework

My Grid is stuck in edit mode after hitting Save but not Cancel.

The cause appears to be: AllowAutomaticInserts="true"

So I'm guessing the EntityDataSource has an error on save - how do I get the error?

Set image for rad tree node depending on its attribute using css

Hello Telerik!

I have my RadTreeView:




<telerik:RadTreeView runat="server" ID="TreeViewUnit"  CssClass="TreeView"

           ShowLineImages="False" Skin="Forest"

    OnDataBound="TreeViewUnit_DataBound" 

    OnNodeClick="TreeViewUnit_NodeClick" 

           meta:resourcekey="TreeViewUnitResource1">

And I have binding in code behind where I set two attributes:

item.Attributes["Item"] = "Unit";

or

item.Attributes["Item"] = "Respondent";

Also I set node images in code behind and it's bad.

item.ImageUrl = imageFolder + "folder-icon.png"

;

node.ImageUrl = imageFolder +

"profile_icon.png";

So I want to do it right way in order to reduce traffic and use CSS for node image.
I tried:

.RadTreeView .rtImg {

background-image: url("/Styles/images/plusminus_icon.png") !important

;

}

.RadTreeView_Forest .rtImg {

background-image: url("/Styles/images/profile_icon.png") !important

;

}

but it does not work.

For example:

.RadTreeView_Forest .rtPlus, .RadTreeView_Forest .rtMinus {

background-image: url("/Styles/images/plusminus_icon.png") !important

}

works perfectly fine for minus sign images.

Any ideas how can I do it? And It will be great if there was a way to select image depending on node attribute. I think I can manage to do it using javascript and DOM elements, but adding images using CSS still a question.
Thanks)

TabStrip & DetailsView - Advice Wanted

I have a requirement to use a DetailsView control to display a shedload of data, more than can reasonably be displayed in the available screen real estate.

So, I thought, "I'll use a TabStrip and split the data up". But, and this is where I wanted some input, would the best option be to:

Put multiple DetailsView controls in my control; one per PageView with different sets of TemplateFields in each DetailsView control, or
Try and put a TabStrip/MultiPage control inside a single DetailsView?

I have to admit to having tried neither of the options I just wondered if anyone had had a similar requirement and had some thoughts about which route to take.

TIA,

Security Exception only in Hosting server

I am using telerik v2010.2.713.40.

The site runs with no errors locally, but when deployed in the hosting server I get the below error. The thing is, the error disappears when the page gets refreshed and works fine thereafter. Then again randomly the error will appear, and refreshing the page will do the trick again. The hosting company confirmed that they run the site on Medium trust environment, so I had updated the pages to work on a Medium Trust environment (inheriting from System.Web.UI.Page, Telerik.Web.UI.IRadAjaxPage and overriding the rendering methods ). Some of other functions does not work as desired , and I think this might be the reason for it. Any help to sort this out will b highly appreciated. Thanks.

Looking for a post

At some point in the last few months I saw an article that showed how to create the drop down menu like the current telerik home page menu with the different product lines grouped together. I would like to use something like that now and of course I cannot find the article!

Can someone point me to where it is?

[Solved] Expanding below other controls

Hey Guys,

I have a couple of RCBs and when they expand, they do not appear below the box, rather below whatever control is under the box.
Sometimes even 2 controls under the box. Can't seem to figure out what is causing it.
I've tried setting EnableScreenBoundaryDetection to false, and Expand Direction to Up/Down. Setting it to Up changes the position, but I do not want to use Up, I need Down.

See it in action here http://cgp.triplestones.com.au/text.aspx

Any ideas? Code below.

<%@ Page Title="" Language="C#" MasterPageFile="~/shared/templates/CGPTest.master" AutoEventWireup="true" CodeFile="text.aspx.cs" Inherits="design_text" %>

<asp:Content ID="Content3" ContentPlaceHolderID="cpPageBody" Runat="Server">

<telerik:RadWindowManager ID="rwmCustom" runat="server"></telerik:RadWindowManager>

<telerik:RadFormDecorator ID="rfdCustom" runat="server" DecoratedControls="All" EnableRoundedCorners="true" />

<h2>Step 2 : Your order details</h2>

<fieldset>

<ul>

<li>Pick type</li>

<li><telerik:RadComboBox ID="rcbPickType" runat="server" Width="250px" OnSelectedIndexChanged="rcbPickType_SelectedIndexChanged" AutoPostBack="true" EnableScreenBoundaryDetection="false" ExpandDirection="Down" /></li>

<li>Pick gauge</li>

<li><telerik:RadComboBox ID="rcbGauge" runat="server" Width="60px" EnableScreenBoundaryDetection="false" ExpandDirection="Down" /></li>

<li>Your Name</li>

<li><asp:TextBox ID="tbName" runat="server" MaxLength="255" width="250px" /></li>

<li>Your Email</li>

<li><asp:TextBox ID="tbEmail" runat="server" MaxLength="255" width="250px" /></li>

<li>Extra instructions</li>

<li><asp:TextBox ID="tbExtraInfo" runat="server" TextMode="MultiLine" Rows="4" MaxLength="2500" width="250px" /></li>

<li> </li>

</ul>

</fieldset>

</asp:Content>

protected void Page_Load(object sender, EventArgs e)

{

// Catch a null order and redirect to the start page

CustomOrder currentOrder = CustomOrder.GetCurrentOrder();

if (currentOrder == null) currentOrder = new CustomOrder(DesignTypes.Text);

if (!Page.IsPostBack)

{

// Bind PickTypes

IEnumerable<XElement> pickTypes = CGP.ShoppingCart.Catalog.GetPickTypes(currentOrder.DesignType);

foreach (XElement pickType in pickTypes)

{

RadComboBoxItem item = new RadComboBoxItem(pickType.Attribute("name").Value + " - " + pickType.Attribute("colour").Value, pickType.Attribute("name").Value + " - " + pickType.Attribute("colour").Value);

item.ImageUrl = pickType.Attribute("imageThumbURL").Value;

rcbPickType.Items.Add(item);

}

// Bind gauges

BindGauges();

}

protected void BindGauges()

{

// Set gauge items in drop down

rcbGauge.Items.Clear();

IEnumerable<XElement> gauges = CGP.ShoppingCart.Catalog.GetGaugesByPickType((rcbPickType.SelectedValue.Split('-')[0]).Trim());

foreach (XElement gauge in gauges)

{

rcbGauge.Items.Add(new Telerik.Web.UI.RadComboBoxItem(gauge.Attribute("name").Value));

}

protected void rcbPickType_SelectedIndexChanged(object sender, RadComboBoxSelectedIndexChangedEventArgs e)

{

BindGauges();

}

Thanks

RadGrid multi row questions

We are evaluating the Telerik controls for web use, and I have a couple of questions that I don't see answered here:

1. Is it possible to set every row to edit mode in the .aspx markup (as opposed to using the Edit property in the code-behind)?
2. Does the built-in binding update only dirty rows (rows that have changed) or does it update *every* row that is posted back in edit mode?

Thanks for any help,

Jeff
