I gotta say, the webmail demo that has an Outlook like appearance is very interesting and amazing to say the least....and I would like to learn how to do something like it. Only thing is, the downloadable code is not available to download like the other demos that Telerik has available. Is there a way I can download this demo code?

Fixed Resource Headers

Hi there,

I am having some difficulty figuring if it is possible to have static resource headers with the Scheduler.
So basically I want the resource headers to remain at the top of the scheduler area when scrolling vertically.
I played around a bit with the HeaderTemplate but couldn't get what I wanted, and can't find any documentation about this.

Any suggestions?

Exporting RadGrid to excel

I need to export a datatable to Excel. I have a cosume control inheridet from RadPageView. basically is a TAB with other control on it. I made a Radgid dynamically like the following:

RadGrid grid = new RadGrid { AutoGenerateColumns = true };

grid.DataSource = dt.DefaultView; // DT is a DataTable

grid.DataBind();

// I include also the grid to my Tab
div.Controls.AddAt(0, grid); // Div a div container in this TAB. by running this code i can see my grid with all columns and rows
but if i add the exportSetting, and export it doesn't show the grid (What actually I want), and no Excel file neither the code that I'm using is:

grid.ExportSettings.OpenInNewWindow = true

grid.ExportSettings.FileName = "CSV Writer

grid.MasterTableView.GridLines = GridLines.Both

grid.MasterTableView.ShowHeader = true

grid.MasterTableView.ExportToCSV();

Any help would be greatly appreciated.

RadRotator and RadWindow

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?

[Solved] 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.

[Solved] 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.
