Omit control from ThemeResolutionService

I know i've seen this, but I couldn't find it.

Basically I just want to omit a single control from changing themes when using the ThemeResolutionService.

I want to theme the entire application except for the pageView control (since it doesn't support the other themes).

Thanks.

Contrasting Colors - Pie Chart

Hi,
I have attached the screenshot of the pie chart developed using RadCharts. By default the chart is showing green, light green, blue and light blue. It does not differentiate the items at the first look itself. A keen observation is required to distinguish between the items.

Instead of light and dark shades, is it possible to show some contrasting colors in the pie charts? Do I need to set any property in the radChart?

Regards,
Arvind Robin Kumar.

Issues with enabling / disabling the PageView Control

Hi Everyone,

First off... I am absolutely in love with this control, kinda bulky to use in design time but fantastic performance at runtime, so big thanks!

I have noticed an issue however that affects the PageView or rather the PageViewPage when the PageView is nested inside another PageViewPage.

When you disable then re-enable the PageView control the child PageViewPages do not re-enable again, you have to manually specify each page as enabled again.

This also happens if you add the PageView control as a chlild of a panel and disable/enable that panel.

I am using the latest version of the Telerik Components WinForms pack with the PageView control in 'Outlook' configuration.

Cheers!

Xavier.

[Solved] Left aligning the labels - Horizontal Stacked Bar chart

Hi,
I am able to display the labels outside the horizontal stacked bar. I have attached the sceenshot of what I have developed. The value 9000 is for the red portion and it is center aligned to it (center aligned to the red portion). Is it possible to align it left?

I tried the following code

cs.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.

StyleSeriesItemLabel.ItemLabelLocation.Outside;

cs.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.

AlignedPositions.Left;

If I set the Aligned position as Left after setting the LabelLocation as Outside, it has no effect.

Following is the code that I am using

radChart1.Series.Clear();

radChart1.IntelligentLabelsEnabled = true;

ChartSeries cs = new ChartSeries();

cs.Items.Add(new ChartSeriesItem(9000));

cs.Appearance.BarWidthPercent = 30;

cs.Appearance.FillStyle.MainColor = Color.Red;

cs.Appearance.FillStyle.SecondColor = Color.Red;

cs.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Outside;

cs.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Left;

cs.Appearance.TextAppearance.TextProperties.Color = System.Drawing.Color.Green;

cs.Type = ChartSeriesType.StackedBar100;

radChart1.Series.Add(cs);

ChartSeries cs1 = new ChartSeries();

cs1.Items.Add(new ChartSeriesItem(1000));

cs1.Appearance.LabelAppearance.Visible = false;

cs1.Appearance.FillStyle.MainColor = Color.Orange;

cs1.Appearance.FillStyle.SecondColor = Color.Orange;

cs1.Type = ChartSeriesType.StackedBar100;

radChart1.Series.Add(cs1);

radChart1.PlotArea.XAxis.Visible = Telerik.Charting.Styles.ChartAxisVisibility.False;

radChart1.PlotArea.YAxis.Visible = Telerik.Charting.Styles.ChartAxisVisibility.False;

radChart1.Legend.Visible = false;

radChart1.ChartTitle.Visible = false;

radChart1.Update();

Stacked Bar graph labels

Hi,
I have attached the screen shot. I want to display the value 1000 according to the width of the red portion. Is it possible to display the value (1000) on top of the horizontal stacked bar (as shown in the second example) if it does not fit inside the red portion?

We need to show the value inside the bar graph if it fits inside it or else it should be displayed on top of the bar.

I have used the following code:

radChart1.Series.Clear();

radChart1.IntelligentLabelsEnabled = true;

ChartSeries cs = new ChartSeries();

cs.Items.Add(new ChartSeriesItem(1000));

cs.Appearance.BarWidthPercent = 30;

cs.Appearance.FillStyle.MainColor = Color.Red;

cs.Appearance.FillStyle.SecondColor = Color.Red;

//cs.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Inside;

cs.Appearance.LabelAppearance.LabelLocation = Telerik.Charting.Styles.StyleSeriesItemLabel.ItemLabelLocation.Outside;

cs.Appearance.TextAppearance.TextProperties.Color = System.Drawing.Color.Green;

cs.Type = ChartSeriesType.StackedBar100;

radChart1.Series.Add(cs);

ChartSeries cs1 = new ChartSeries();

cs1.Items.Add(new ChartSeriesItem(9000));

cs1.Appearance.LabelAppearance.Visible = false;

cs1.Appearance.FillStyle.MainColor = Color.Orange;

cs1.Appearance.FillStyle.SecondColor = Color.Orange;

cs1.Type = ChartSeriesType.StackedBar100;

radChart1.Series.Add(cs1);

radChart1.PlotArea.XAxis.Visible = Telerik.Charting.Styles.ChartAxisVisibility.False;

radChart1.PlotArea.YAxis.Visible = Telerik.Charting.Styles.ChartAxisVisibility.False;

radChart1.Legend.Visible = false;

radChart1.ChartTitle.Visible = false;

radChart1.Update();

[Solved] Databinding List<Generics>

SiteHello, I have a problem when I assign a generic list to the chart object,
this is my class

public class cs_itemspedido

{

private string referencia;

private int cantidad;

private string nombre;

private double pesoxref;

private double valor;

private int osa;

public int Osa

{

get { return osa; }

set { osa = value; }

}

public double Valor

{

get { return valor; }

set { valor = value; }

}

public double PesoXRef

{

get { return pesoxref; }

set { pesoxref = value; }

}

public string Nombre

{

get { return nombre; }

set { nombre = value; }

}

public string Referencia

{

get { return referencia; }

set { referencia = value; }

}

public int Cantidad

{

get { return cantidad; }

set { cantidad = value; }

}

/// <summary>

/// Peso Total

/// </summary>

public double Peso_Total

{

get { return (cantidad * pesoxref); }

}

/// <summary>

/// Valor total X item

/// </summary>

public double Valor_Total

I just want to show the X axis the value of the property (Referencia) and the axle and (Peso_Total) value.

from char/varchar to gridviewbooleancolumn

hi,

Recently I downloaded trial version of your products, I think those are good components makes developing stage easier. My question is. Database doesn't support boolean datatypes, so, I use char(1) to represent 'Y', 'N' values, but I need this be displayed by gridviewcheckboxcolumn, how can I do to make it possible since gridviewcheckboxcolumn must be binded to a boolean column into datatable and no way to translate string column datatable into boolean column datatable?

'Y' - On

'N' - Off

thanks

GridView ViewDefinition problem

Hi

In my project I have the following senario:

ColumnGroupsViewDefinition

view = new ColumnGroupsViewDefinition();

view.ColumnGroups.Add(new GridViewColumnGroup("Group"));

view.ColumnGroups.Add(new GridViewColumnGroup("ID"));

view.ColumnGroups.Add(new GridViewColumnGroup("Amount"));

view.ColumnGroups.Add(new GridViewColumnGroup("Date "));

view.ColumnGroups.Add(new GridViewColumnGroup("method"));

view.ColumnGroups.Add(new GridViewColumnGroup("request"));

view.ColumnGroups[3].Rows.Add(new GridViewColumnGroupRow());

view.ColumnGroups[4].Rows.Add(new GridViewColumnGroupRow());

view.ColumnGroups[5].Rows.Add(new GridViewColumnGroupRow());

view.ColumnGroups[3].Rows[0].Columns.Add(this.grid1.Columns["Now"]);

view.ColumnGroups[3].Rows[0].Columns.Add(this.grid1.Columns["yesterday"]);

view.ColumnGroups[4].Rows[0].Columns.Add(this.grid1.Columns["now"]);

view.ColumnGroups[4].Rows[0].Columns.Add(this.grid1.Columns["yesterday"]);

view.ColumnGroups[5].Rows[0].Columns.Add(this.grid1.Columns["now"]);

view.ColumnGroups[5].Rows[0].Columns.Add(this.grid1.Columns["yesterday"]);

DataTable

table = new DataTable();

table.Columns.Add(

"grp",typeof(string));

table.Columns.Add("ID",typeof(string));
table.Columns.Add("Amt",typeof(string));
table.Columns.Add("date",typeof(string));
table.Columns.Add("metd",typeof(string));
table.Columns.Add("req",typeof(string));

grid1.MasterGridViewTemplate.AutoGenerateColumns = false;

grid1.DataSource = table;

grid1.ViewDefinition = view;

My problem is that I get "Object reference not set to an instance of an object." error on last line that is:
"grid1.ViewDefinition = view;"

I have tryed many things to solve this but I couldn't.

Any help will be appreciated.

Thanks In advance.
