Hello.

I have a scenario where I need to draw a RED line as an upper marker like in this example.
http://demos.telerik.com/aspnet-ajax/htmlchart/examples/databinding/staticitems/defaultcs.aspx

The line itself is no problem, but can I change the color when making the series programically?

Telerik RadGrid Error - GridPagerStyle does not have PageSizeControlType

A co-worker gave me a modified version of a file and now I can't get the project to compile in Visual Stuio. As far as I know, we're both using the same source code. I tried copying the Telerik .dll files from the server (where the code is working) and referencing those files, but I am still getting the same error. The version of my Telerik .dll files is 2012.1.215.40. Can you help me with this?

The errors I am getting are

Type 'Telerik.Web.UI.GridPagerStyle' does not have a public property named 'PageSizeControlType'.

Content ('</PagerStyle>') does not match any properties within a 'Telerik.Web.UI.GridTableView', make sure it is well-formed.

The error is from this line:

<PagerStyle PageSizeControlType="RadComboBox"></PagerStyle>

If I comment out that line, I get a whole host of other error messages that are similar (Telerik.XXX does not have a public property named YYY).

Can't Get Sorting to Work

I am using ASP.NET C# for my RadGrid and cannot get sorting to work. I have tried a couple of different ways to do it that I have found on this site, and some code from other sites, but the grid remains sorted the default way each time I try. Someone please help!

<telerik:RadGrid runat="server" ID="radProductsGrid" Skin="Default" AllowSorting="true" AllowPaging=

"true"

OnSortCommand="radProductsGrid_SortCommand" OnNeedDataSource="radProductsGrid_NeedDataSource"
AutoGenerateColumns= "false" GridLines="None" ShowGroupPanel="false" PageSize="100">

<MasterTableView Width="100%" AllowMultiColumnSorting="false" AllowNaturalSort="false"
AllowCustomSorting="true" AllowSorting="true" AutoGenerateColumns="false">

<Columns>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ItemNumber"
DataField="ItemNumber" HeaderText="Item Number" UniqueName="ItemNumber">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="ProductName"
DataField="ProductName" HeaderText="Product Name" UniqueName="ProductName">

</telerik:GridBoundColumn>

<telerik:GridBoundColumn ReadOnly="true" AllowFiltering="true" SortExpression="CategoryName"
DataField="CategoryName" HeaderText="Category Name" UniqueName="CategoryName">

</telerik:GridBoundColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

protected void radProductsGrid_SortCommand(object sender, GridSortCommandEventArgs e)

{

GridTableView tableView = e.Item.OwnerTableView;

if (e.SortExpression == "ItemNumber")

{

e.Canceled = true;

GridSortExpression expression = new GridSortExpression();

expression.FieldName = "ItemNumber";

if (tableView.SortExpressions.Count == 0 || tableView.SortExpressions[0].FieldName

                        != "ItemNumber")

{

expression.SortOrder = GridSortOrder.Descending;

}

else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Descending)

{

expression.SortOrder = GridSortOrder.Ascending;

}

else if (tableView.SortExpressions[0].SortOrder == GridSortOrder.Ascending)

{

expression.SortOrder = GridSortOrder.None;

}

tableView.SortExpressions.AddSortExpression(expression);

tableView.Rebind();

}

RadDatePicker - selecting a day is getting the previous day

As a developer, you need to consider the various time zones which your users are located on.

Some countries use the Daylight saving time (DST) /summer time/ which is the practice of advancing or adjusting backward clocks one hour near the start of a temperate mid-season (spring or autumn). Unfortunately, this adjusting is error-prone to software components and leads to unwanted behavior when using a RadDatePicker.

For instance, let’s assume that you have a web site for renting out various halls or principal rooms for meetings and social affairs, and you use a RadDatePicker to schedule the event date. I am a user from Brazil and with meu amor decided our wedding date to be on October the 20^th. However, every time I select this date, the picker re-selects it to be the 19^th. I contact you, the web administrator, and ask you “Does destiny want to prevent me from making a big mistake or is this a bug? What is happening, amigo?”

Here is the explanation:

Most probably, I have a Brazilian culture set on my computer:

As noticed in the image, the clocks will be advanced by 1 hour on that date. And since the RadDatePicker takes the zero hour by default, it is actually still on the previous day, because the 20^thstarts at 01:00 o’clock. To work around this issue, you can use the client side events of the picker:

<telerik:RadDatePicker ID="RadDatePicker1" runat="server">

<DateInput runat="server">

<ClientEvents OnValueChanging="valueChanging" OnValueChanged="valueChanged" />

</DateInput>

</telerik:RadDatePicker>

JavaScript:

var selectedValue = null;

var isDST = false;

function valueChanging(sender, args) {

if (isDST) {

args.set_newValue(selectedValue + " 01:00 AM");

isDST = false;

}

selectedValue = args.get_newValue();

}

function valueChanged(sender, args) {

if (selectedValue) {

if (selectedValue.indexOf(args.get_newValue()) < 0) {

isDST = true;

sender.get_owner().set_selectedDate(); // used only to trigger selecting event

}

}

function CharacterCheck(text, e) {

text.value = text.value.replace(/[^0-9a-zA-Z]/gi, '');

}

RadChart Multiple Series with DateTime labels on Xaxis

Hi,
how it's possible create a chart with multiple line series?

for example in my db I have:

Datetime Value
06/10/2011 06:00 8
06/10/2011 06:10 12
06/10/2011 06:15 9
06/10/2011 06:18 6
06/10/2011 06:21 9

I want create multiple line series for selected datetime Range where the x-axis is DateTime and the y-axis Value.

I have tried like this but its not plotting its showing only empty series..
series = new ChartSeries();
series.Type = ChartSeriesType.Line;
series.Name = "RTD"; series.Clear();
ChartSeriesItem item = new ChartSeriesItem();
item.YValue = Convert.ToDouble(Sqlds.Tables[0].Rows[i][0]);
series.Items.Add(item);
chart1.PlotArea.XAxis[index].TextBlock.Text = DateTime;
//Axis
chart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "DateTime";

chart1.PlotArea.XAxis.AutoScale = false;
chart1.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.LongDate;
chart1.PlotArea.XAxis.Appearance.CustomFormat = "mm/dd/yyyy hh:mm:ss";
chart1.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = 90;

//Axis Y
chart1.PlotArea.YAxis.AxisLabel.TextBlock.Text = "Value";
chart1.Series.Clear();
chart1.Series.Add(series2);
chart1.Series.Add(series1);
chart1.Series.Add(series);
thanks

If you click on the graphs on the Accordions , you will see they are supposed to be Dynamic , but they dont change because there is an Ajax error that looks like this
