RadGridview Relation expanded

Hi ,

I am using the relational gridview. when i click the button , i want the node will be expanded by condition . Follow the link : https://docs.telerik.com/devtools/winforms/controls/gridview/hierarchical-grid/how-to/expanding-all-rows . is it the best way to do it ? because i see it is really slow when expanding.

void ExpandAllRows(GridViewTemplate template, bool expanded) {
foreach(GridViewRowInfo row in template.Rows) {

if(row.Tag == conditionID){
row.IsExpanded = expanded;

}
}
if (template.Templates.Count > 0) {
foreach(GridViewTemplate childTemplate in template.Templates) {
ExpandAllRows(childTemplate, true);
}
}
}

LineSeries points not connected properly.

Hello,

When using the following code my data points don't get connected properly, as seen in picture attached.
The picture attached is from only one Series object.The data is a list of objects with properties amount (an int) and datetime which is a value like this xxh30 or xxh00.

DateTimeCategoricalAxis categoricalAxis = new DateTimeCategoricalAxis();

categoricalAxis.PlotMode = Telerik.Charting.AxisPlotMode.BetweenTicks;

categoricalAxis.DateTimeComponent = Telerik.Charting.DateTimeComponent.Hour;

categoricalAxis.LabelFormat = "{0:HH:mm}";

foreach (RadCheckedListDataItem item in radCheckedDropDownListDates.CheckedItems)

{

List<MonitoringToolDomain.FILESPROCESSED> queryChart = new List<MonitoringToolDomain.FILESPROCESSED>();

queryChart = MonitoringToolCore.FilesProcessed.QueryLineChart((DateTime?)item.DataBoundItem, fromHour, toHour);

queryChart.Select(c => { c.DATETIME = CreateDateFromTime(2015, 12, 12, c.DATETIME); return c; }).ToList();

LineSeries test = new LineSeries

{

DataSource = queryChart,

ValueMember = "AMOUNT",

CategoryMember = "DATETIME",

IsVisibleInLegend = true,

LegendTitle = item.DataBoundItem.ToString()

//CombineMode = Telerik.Charting.ChartSeriesCombineMode.None

};

test.HorizontalAxis = categoricalAxis;

radChartView.Series.Add(test);

}

radChartView.ShowLegend = true;

}



 I have a second problem, not sure if I should post it here but I don't want to create too many new threads. I would like to compare charts from different days as in my second attached picture. If I create different line series, the charts appear sequentially because they don't have the same date. The solution I'm using at the moment is to change the DATETIME parameter in all of my objects to have the same date part. Is there any other way to do this ? 



What I'm doing now :

queryChart.Select(c => { c.DATETIME = CreateDateFromTime(2015, 12, 12, c.DATETIME); return c; }).ToList();

Change the base color of the "Default" theme

I've read posts about color blending and I think that is no longer available. I would like to create some theme options for the user to pick from a color dialog (attached image) and apply that color as the color of the "Default" theme. What is the way to do that now?

Thank you,
Gary

Closing an MDI Child Form

Hello,

I create a RadForm (named mainForm) with a RadDock.

I set the mainForm.MdiContainer = true and the radDock1.AutoDetectMdiChildren = true and the chilForm.MdiParentwith = mainForm (for all children form).

When I close my mainForm, in the FormClosing event I call radDock1.CloseAllWindows() and FormClosing event of MDI children form fires.

However can you tell me if is it possible to show (to active) every child form when FormClosing is called ?

Thank you

Bests regards

I use backstageview in my ribbonbar. I've enabled AutoScroll and set the AutoScrollMinSize in backstageview to use the scrolling bar if the window is too small.

But I've found a display issue when I drag the mouse to scroll. Please see the attached picture.
