Data entry doesn't doesn't update localdb

I've bound a RadBinding Navigator and RadDataEntry to a localdb binding source. At runtime I can browse the db entries but if I make any changes or add a table entry....it isn't saved into the table. Do I have to do individual insert/update sql for each field? For some reason, looking at the documentation I thought the changes would be automatically stored?

[Solved] How to remove horizontal border in group view

Hello,

I'd like to remove the horizontal border in a grid within groups (GridViewColumnGroup not GroupDescriptor).

See the attached image, the green (verticals) borders are ok the red (horizontal) borders between the cells in the group are the ones I'd like to remove. (For normal cells and cells of the summary row)

I've tried the normal formatting events, but I found no information if a cell/row is inside a group?

So is this possible at all?

--

Also the GridViewColumnGroupRow.ColumnCollection is marked deprecated, so what is the best way to do this (the ColumnNameCollection dosen't help)?

GridViewColumnGroupRow groupRow = new GridViewColumnGroupRow();

groupRow.Columns.Add(this.kMRadGridView1.Columns["column"]);

PivotGrid with custom aggregates group TimeSpan and bounded ChartView

Good day!

I use PivotGrid in conjunction with ChartView.
As one of the columns of data to implement a class for adding a field of type TimeSpan.

This code implements summary of TimeSpan:

/// <summary>

/// Computes the sum of TimeSpan items during pivot grouping

/// </summary>

public class TimeSpanSum : AggregateFunction

{

protected override AggregateValue CreateAggregate(Type dataType)

{

return new TimeSpanAggregateValue();

}

public override string DisplayName

{

get { return PivotGridLocalizationProvider.CurrentProvider.GetLocalizedString(PivotStringId.Sum); }

}

protected override void CloneCore(Cloneable source)

{

//

}

protected override Cloneable CreateInstanceCore()

{

return new TimeSpanSum();

}

public override string ToString()

{

return "Sum";

}

This code adding aggregate description:

dataProvider.AggregateDescriptions.Add(new PropertyAggregateDescription

{

PropertyName = ObjectHelper<PivotGridUnitStateDto>.GetPropertyName(x => x.Duration),

CustomName = "Duration",

AggregateFunction = new TimeSpanSum(),

StringFormatSelector = new TimeSpanStringFormatSelector()

});

But ChartView generate exception on paint any data:

Unable to bring the object type "System.TimeSpan" type "System.IConvertible". (Mscorlib)

------------------------------

Program Location:

в System.Convert.ToDouble(Object value)

в Telerik.WinControls.UI.PivotGridChartDataProvider.UpdateChartCore()

в Telerik.WinControls.UI.PivotGridChartDataProvider.UpdateChartData()

в Telerik.WinControls.UI.PivotGridChartDataProvider.updateTimer_Tick(Object sender, EventArgs e)

How can I fix this error?

Prevent Editor opening depending on the node

Hello

I have found that we can allow the editor on the radtreeview level with the AllowEdit Property.

But on my treeview I have some nodes which should be editable and other which aren't.

How could I handle this ? Is it possible to prevent the initialization of the editor for some specific node ?

Thanks for you support

[Solved] How to set a fill primitive programataically

Hello,

I need to set the fill primitive of a control programatically. Attached is a picture of what I need to accomplish.

From the tree on the left (of the attached image) you can see I'm setting DockLayoutPanel.ToolwindowCaptionElement.FillPrimitive to the color red. Works great from within the designer, but I need to do it via program control.

It seems like this control, which is in a raddock, is part of a tool tab strip so I've tried...

toolTabStrip11.SplitPanelElement.Fill.BackColor = Color.Red;

toolTabStrip11.SplitPanelElement.ForeColor = Color.Red;

and several other variations, but none of them changed the color. Is there a way to do this grammatically?

Thanks to anyone who can solve this,

Steve
