Not sure what I'm doing wrong. I cannot databind a RangeBarSeries.

In the below test I took the Demo binding example and added a RangeBarSeries. The Area and Line series show fine but the RangeBar does not show. ( See Attached)

Here is the code:

protected void Page_Load(object sender, EventArgs e)

{

string[] tempTitles = { "In the Heart of the Sea", "The Hunger Games: Mockingjay - Part 2", "Krampus", "The Good Dinosaur", "Creed", "Spectre", "The Night Before", "The Peanuts Movie", "Spotlight", "Brooklyn" };

foreach (string one in tempTitles)

{

RangeBarChart.PlotArea.XAxis.Items.Add(one);

}

List<MarketShareData> chromeData = new List<MarketShareData>();

chromeData.Add(new MarketShareData(10.8, 23.8));

chromeData.Add(new MarketShareData(11.6, 24.1));

chromeData.Add(new MarketShareData(12.3, 25.0));

chromeData.Add(new MarketShareData(13.6, 25.6));

chromeData.Add(new MarketShareData(14.5, 25.9));

chromeData.Add(new MarketShareData(15.9, 27.9));

chromeData.Add(new MarketShareData(16.7, 29.4));

chromeData.Add(new MarketShareData(17.0, 30.3));

chromeData.Add(new MarketShareData(17.3, 30.5));

chromeData.Add(new MarketShareData(19.2, 32.3));

chromeData.Add(new MarketShareData(20.5, 33.4));

chromeData.Add(new MarketShareData(22.4, 34.6));

RangeBarChart.DataSource = chromeData;

RangeBarChart.DataBind();

}

public class MarketShareData

{

public MarketShareData(double marketShare2010, double marketShare2011)

{

_marketShare2010 = marketShare2010;

_marketShare2011 = marketShare2011;

}

private double _marketShare2010;

public double MarketShare2010

{

get { return _marketShare2010; }

set { _marketShare2010 = value; }

}

private double _marketShare2011;

public double MarketShare2011

{

get { return _marketShare2011; }

set { _marketShare2011 = value; }

}

Enable text selection in TreeView

I have the following problem:
I'm putting an arbitrary html, enclosed in HtmlGenericControl, in the leaf nodes of a tree control. I want the users to be able to select this html (or portions of it) with the mouse and then copy it into the clipboard. The selection works fine in Firefox, but not in IE (7 and 8).

Does anybody know how to solve this issue?

Format Individual Cells of RadGrid

Hello,

I have an application which deliver data from a SQL query in the form of a RadGrid. I have business rules that require me to high cells red or green. Whether the cells are red or green is stored in the DB. I also need to hyperlink from cells to a URL.

But each cell will have it own URL and it own color. So the formatting either needs to be done after the RadGrid is populated by iterating through each cells, or we need to pass more data than just what values are displayed in the Grid, so that the Grid has the information to do the formatting.

I hope that is clear. TIA.

Calendar as customized Datapicker

Hi,

In our application we have already implemented leagcy calendar popup mechanism, now I'm planning to replace them with Rad Calendar. we have a combination of textbox followed by a calendar control to pick the dates and assign it to the textbox. I just want to replace my calendar with the Rad datapicker calendar and upon slecting the date it should assign to my existing textbox. I tried with some samples in this site by using Rad calendar control as Datapicker, but it is not showing as similar like a Rad datepicker calendar, (it doesn't show like a floating calendar). Please let me know in detail (I'm not that good at UI) on how to achieve this functionality. Thank you!

OnError called twice

Hi

I am using below code for datepicker

<telerik:RadDatePicker ID="RadDatePicker1" runat="server" MinDate="2015/7/7">

<DateInput runat="server">

<ClientEvents OnError="pickerError" />

</DateInput>

</telerik:RadDatePicker>

and below is my javascript code

function pickerError(sender, args)

{

alert("Please fix the dates");

}

So when we enter an invalid date say 2015/2015/2015 the pickerError method is called and an alert box is shown but when we try to edit the date (click on the textbox) the pickerError method is called again. Does anyone know why this is happening?

Please note that this was working fine in Q2 2012, but we have upgraded to Q2 2015.

Also, I have watched args.get_reason() and in both cases its value is 1.

Thanks
