We have a RadWindowManager on a Page. We open RadWindows using Javascript

var oManager = GetRadWindowManager();

oManager.open("./Popup.aspx", "Popup");

Everything works fine.
When I dynamically add a RadRotator to my page using the code below the RadWindow Script stops working. Instead of opening a window the page does a postback.

radRotator.ID = "twitter" + ContentItem.ContentItemId;

radRotator.CssClass = "RSSFountainClass";

radRotator.RotatorType =(TwitterRotatorType>0) ? TwitterRotatorType : RotatorType.AutomaticAdvance;

radRotator.ScrollDirection = RotatorScrollDirection.Up;

radRotator.ScrollDuration = ScrollDuration;

radRotator.FrameDuration = FrameDuration;

radRotator.ItemTemplate = new

RotatorItemTemplate(ContentItem, RSSItemTemplateClass, RSSItemDateTimeClass, RSSItemDateClass, RSSItemTimeClass, RSSItemTitleClass);

radRotator.Height = new Unit(Height, UnitType.Pixel);

radRotator.DataSource = RSSDataSource();

radRotator.InitialItemIndex = -1;

radRotator.DataBind();

Controls.Add(radRotator);

When i disable the handler, the script works again.

Below the handler code:

private class RotatorItemTemplate : ITemplate

{

Label literal;

private ContentItem ContentItem { get; set; }

private string RSSItemTemplateClass { get; set; }

private string RSSItemDateTimeClass { get; set; }

private string RSSItemDateClass { get; set; }

private string RSSItemTimeClass { get; set; }

private string RSSItemTitleClass { get; set; }

public RotatorItemTemplate(ContentItem contentItem, string rssItemTemplateClass, string rssItemDateTimeClass, string rssItemDateClass, string rssItemTimeClass, string rssItemTitleClass)

{

literal = new Label();

ContentItem = contentItem;

RSSItemTemplateClass = rssItemTemplateClass;

RSSItemDateTimeClass = rssItemDateTimeClass;

RSSItemDateClass = rssItemDateClass;

RSSItemTimeClass = rssItemTimeClass;

RSSItemTitleClass = rssItemTitleClass;

}

public void InstantiateIn(Control container)

{

literal = new Label();

literal.DataBinding += TwitterItem_ItemDataBound;

container.Controls.Add(literal);

}

/// <summary>

/// TwitterItem_ItemDataBound Method

/// </summary>

/// <param name="sender">An object</param>

/// <param name="e">An EventArgs</param>

/// <returns>A void</returns>

private void TwitterItem_ItemDataBound(object sender, EventArgs e)

{

Label labelControl = (Label)sender;

RadRotatorItem rotatorItem = (RadRotatorItem)labelControl.NamingContainer;

XPathNavigator xPathNavigator = ((IXPathNavigable)rotatorItem.DataItem).CreateNavigator();

HtmlGenericControl htmlGenericControlItem = new HtmlGenericControl();

htmlGenericControlItem.Attributes.Add("onclick", "window.open('" +

((ContentItem.FileTitle == TwitterType.Follow.ToString())

? xPathNavigator.SelectSingleNode("link").Value

: xPathNavigator.SelectSingleNode("link/@href").Value)

+ "', '_blank')");

if (!string.IsNullOrEmpty(RSSItemTemplateClass))

htmlGenericControlItem.Attributes.Add("class", RSSItemTemplateClass);

HtmlGenericControl htmlGenericControlDateTime = new HtmlGenericControl();

if (!string.IsNullOrEmpty(RSSItemDateTimeClass))

htmlGenericControlDateTime.Attributes.Add("class", RSSItemDateTimeClass);

HtmlGenericControl htmlGenericControlTime = new HtmlGenericControl();

if (!string.IsNullOrEmpty(RSSItemTimeClass))

htmlGenericControlTime.Attributes.Add("class", RSSItemTimeClass);

htmlGenericControlTime.Controls.Add(new LiteralControl(

((ContentItem.FileTitle == TwitterType.Follow.ToString())

? Convert.ToDateTime(xPathNavigator.SelectSingleNode("pubDate").Value).ToShortDateString()

: xPathNavigator.SelectSingleNode("author/name").Value))

);

HtmlGenericControl htmlGenericControlDate = new HtmlGenericControl();

if (!string.IsNullOrEmpty(RSSItemDateClass))

htmlGenericControlDate.Attributes.Add("class", RSSItemDateClass);

htmlGenericControlDate.Controls.Add(new LiteralControl(

((ContentItem.FileTitle == TwitterType.Follow.ToString())

? Convert.ToDateTime(xPathNavigator.SelectSingleNode("pubDate").Value).ToShortTimeString()

: xPathNavigator.SelectSingleNode("updated").Value))

);

htmlGenericControlDateTime.Controls.Add(htmlGenericControlDate);

htmlGenericControlDateTime.Controls.Add(htmlGenericControlTime);

htmlGenericControlItem.Controls.Add(htmlGenericControlDateTime);

HtmlGenericControl htmlGenericControlTitle = new HtmlGenericControl();

if (!string.IsNullOrEmpty(RSSItemTitleClass))

htmlGenericControlTitle.Attributes.Add("class", RSSItemTitleClass);

htmlGenericControlTitle.Controls.Add(new LiteralControl(

((ContentItem.FileTitle == TwitterType.Follow.ToString())

? xPathNavigator.SelectSingleNode("title").Value

: xPathNavigator.SelectSingleNode("content").Value)));

htmlGenericControlItem.Controls.Add(htmlGenericControlTitle);

labelControl.Controls.Add(htmlGenericControlItem);

}

Can anyone help me to solve this problem? Why does the page perform a postback after adding the Rotator handler.

blank rows appearing in exported excel file

I am trying to figure out why a blank row is appearing between each row of data in the excel file that gets exported from my radgrid. Here is how I am doing the export:

grdMetricsClosed.ExportSettings.ExportOnlyData = true;

grdMetricsClosed.ExportSettings.IgnorePaging = true;

grdMetricsClosed.ExportSettings.OpenInNewWindow = true;

foreach (GridColumn col in grdMetricsClosed.MasterTableView.RenderColumns)

{

col.Visible = true;

}

grdMetricsClosed.MasterTableView.ExportToExcel();

I am at a loss as to why that is happening. Anyone run into this and if so, what is the solution?

Get GridEditableItem for preinserted item

Hello,
I need to get to the GridItem for a record that I am inserting. I'm actually changing the value of one of the controls in my EditItemTemplate.
Basically, the idea is the user performs some action while entering the information, and then through server-side code the value of a particular control gets changed.
But, I'm doing this outside the InsertCommand event, and can't figure out how to find it inside the RadGrid control.

Undesirable ToggleButton behavior in IE

I have a set of toggle buttons on a form. I want a custom image that changes states depending on a state kept in the code-behind. The code definition for the toggle buttons is here:

<telerik:RadButton ID="RadButtonOptionCapital" runat="server" OnToggleStateChanged="RadButtonOptionCapital_ToggleStateChanged"

ToggleType="CustomToggle" ToolTip="Capital" ButtonType="ToggleButton"

AutoPostBack="True" BorderStyle="None" >

<ToggleStates>

<telerik:RadButtonToggleState PrimaryIconUrl="Images/Dollar-Ironwood-16.png" Selected="true" />

<telerik:RadButtonToggleState PrimaryIconUrl="Images/Dollar-Grey-16.png" />

</ToggleStates>

</telerik:RadButton>

I have three of these in a row, each in their own div such that they line up nicely. In IE only, when I click one of the toggle buttons it alters its position to a few pixels higher. See the attached images. This works fine in Chrome and Firefox. Any suggestions for a workaround?

If you're wondering what I do in OnToggleStateChanged, I change the tooltip text and refresh a grid based on the setting. However I have removed the OnToggleStateChanged and it still happens. The only way to make it not happen is to set AutoPostBack to False.

Also, I think the initial position of the image is wrong, not the position after it's toggled. It remains in the toggled position no matter how many times I click it, and the final position matches the position that Chrome and Firefox renders it at.

Catching The Value of the Selected Item(s)

I am using a C# code behind page, and have written some custom buttons with OnClick events on that code behind page. I simply need to determine which items are selected in the FileExplorer so that I can pass the value of the File Name(s) to a Microsoft SQL Database. Can you tell me how to find the file names of the selected files? Thank you.

Hi:
I am using liquid css with my RadDatePicker, and it works fine in Casini (VS Dev), but not in IIS7. The Css is as follows:

.field

{

float: left;

padding: 5px 30px 5px 0px;

height: 35px;

}

.field h5

{

font-size: .9em;

font-weight: bold;

padding: 0;

margin: 0;

}

And the following code demonstrates the issue:

<%@ Page Language="VB" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

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

<script runat="server">

<body>

<form id="form1" runat="server">

</telerik:RadScriptManager>

<telerik:RadAjaxPanel ID="orderSelectionRadAjaxPanel" runat="server" CssClass="ScreenWidth">

<div style="width: 100%; margin: 0px; padding-top: 20px;">

<div class="field">

<div class="field">

</telerik:RadDatePicker>

<asp:RequiredFieldValidator ID="startValidator1" runat="server"

</div>

<div class="field">

</telerik:RadDatePicker>

<asp:RequiredFieldValidator ID="endValidator1" runat="server"

ControlToValidate="endRadDatePicker" ValidationGroup="selectionValidationGroup"

/>

</div>

<div class="field">

<h5>Customers:</h5>

</div>

</telerik:RadAjaxPanel>

</form>

</body>

</html>

Combo Box and Menu intertwined

I read the message that you folks are working with short staff the next couple of days...This can wait until next week. The page is not in production yet.

I am having a problem with the combo box dropdown and the menu (both Telerik's). The "text only" portion of the menus is showing through the dropdown of the combo box. I have tried ZIndex settings of 750 on the combo box and 500 on the menu to no avail.

I have attached a screen capture of the problem. Any suggestions as to how to resolve this would be appreciated.

Thanks in advance and have a great holiday week-end over there. We're all having to work today.

Multiple Entity Framework 4 Entities & OnNeedDataSource

Hi, how can I bind a RadGrid when I need to include details from more than one entity?

I have the following code that runs, definitely brings back data but does not show anything in my grid (with AutoGenerateColumns set to "true"):

protected void MyGrid_OnNeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

using (var context = new MyContainer())

{

var d = from data in context.ParentEntity.Include("ChildEntities")

select new

{

data.ParentProperty,

data.ChildEntity.FirstOrDefault().ChildProperty

};

this.MyGrid.DataSource = d.ToList();

}

I don't mind admitting my LINQ to Entities knowledge is "ongoing" but you can see what I am trying to do: for every ParentEntity, get me their properties and for every ChildEntity under that, get me their properties as well. I want the grid to display those.

Because the ChildEntity may not necessarilly immediately have a ParentEntity, I can't do a master / detail view with two grids.
