Hello, we have a program requirement where the user can select one or multiple rows and then choose to "highlight" those rows from a given set of colors.
This process can be repeated multiple times allowing the user to color code rows in different colors at a time.
The work flow ->
User selects rows
User then chooses the Highlight Rows menu option which is a drop down for different colors.
The rows background are then set to that color.

Rinse -> repeat as the user sees fit.

There is also a reset option that resets all the rows back to the default colors.

I did not see how to perform this specific type of background color assignment in either the Formatting Rows or Conditional Formatting Rows help sections.

If you could please help us understand how to perform this specific kind of row formatting, it would help us to be able to convert to the Telerik RadGridView from our previous 3rd party grid control.

Export with Console Application

Hi,

Is it possible to databind a grid and exports it to excel from a ConsoleApplication project ?

I tried the LoadElementTree method, that doesn't work, I can't get my grid populated with data using the datasource member.
The only working method what the Grid.Rows.Add.

The other issue is that the ExportVisualSettings can't be set to true or you'll get an exception.

Is there a clean way to get it to work ?

Thanks,

GridView

Chartview PieChart

If I have two pie charts next to each other how do I make their circumference the same size.

I have tried Chartview.View.Margin. Setting it to the same value does not make them the same size.

How to get series name from clicking Bar Element Label

I have a bar chart and I'm trying to get the name of the series when I click on the Label Element next to the bar.

However, I can't find any documentation on how to add a click event to the label element (in the image attached, I'm talking about the $10000 label).

I have a SelectedPointChanged event registered to my RadChartView control and that works great, but only works when the bar is clicked not the label next to it.

private void selectionController_SelectedPointChanged(object sender, ChartViewSelectedPointChangedEventArgs args)

{

var series = args.NewSelectedSeries;

}

Rows.Count = 0 But SelectedRows.Count =1 Is there a bug?

I'm using static BindingList as DataSource:

public class Items

{

public static DateTime FechaTrabajo = DateTime.Today;

public static MyBindingList<Pedidos> pedidos = new MyBindingList<Pedidos>();

public static async Task Load(DateTime fechaTrabajo)

{

try

{

pedidos.Clear();

FechaTrabajo = fechaTrabajo;

pedidos.Add(await SSEService.Instance.GetPedidos(fechaTrabajo));

pedidos.ListUpdated();

}

catch (Exception) { }

}

Where MyBindingList extends BindingList and ListUpdated is like:

public void ListUpdated()

{

this.OnListChanged(new ListChangedEventArgs(ListChangedType.Reset, 0));

}

I'm using Items.pedidos as datasource for the Grid and all is working perfect, grid is updating data when needed, but when I need selectedrows, if Items.pedidos has had data and now is empty. When I call:

private void bNuevoPalet_Click(object sender, EventArgs e)

{

int rows = this.radGridView1.Rows.Count;

int srows = this.radGridView1.SelectedRows.Count;

if (this.radGridView1.SelectedRows.Count > 0)

{

Pedidos ped = this.radGridView1.SelectedRows[0].DataBoundItem as Pedidos;

if (ped != null)

{

fPedido.ShowMe(ped);

}

rows = 0

but srows = 1

Re-ordering PDF thumbnails and combining into new documents

I am working with the RadPdfViewer and RadPdfStreamWriter components, and I have the need to be able to display thumbnails of each page of a group of PDF documents and allow a user to re-arrange the thumbnails to group together into new documents. This is the digital equivalent of taking a stack of papers and laying them out on a table to pick and choose how to assemble the pages back into distinct documents

I understand how to display the individual documents and the thumbnails of the pages, and I understand how to merge and split PDF documents using the PdfStreamWriter and PdfStreamReader, but I have not found a way to load multiple documents into a single viewer control and allow users to re-order the thumbnails. Is this functionality that is supported in the current WinForms controls?
