Editing Excel Export

Hi, I used some excel export code previous posted on a thread. It works great, but I'm wondering if we can intercept midway. I'm looking to add a value on the top row then followed by the chart.

public static void Export(RadGridView grid)

{

const string extension = "xls";

var dialog = new SaveFileDialog

{

DefaultExt = extension,

Filter = String.Format("{1} files (*.{0})|*.{0}|All files (*.*)|*.*", extension, "Excel"),

FilterIndex = 1

};

if (dialog.ShowDialog() != true)

{

return;

}

using (var stream = dialog.OpenFile())

{

var exportOptions = new GridViewExportOptions

{

Format = ExportFormat.ExcelML,

ShowColumnHeaders = true,

ShowColumnFooters = true,

ShowGroupFooters = false,

};

exportOptions.Items = (IEnumerable)grid.ItemsSource;

grid.Export(stream, exportOptions);

}

Changing the selected row colour in the Rad Grid View

I've been trying to change the selected row colour from the default grey to blue. I've been able to change the un-selected row colour, but when I do that the selected row turns to a kinda orange, and I can't change it from there.

Would anyone be able to help work out how to change this?

Add small delay before filtering?

We're using RadAutoCompleteBox together with a FilteringBehavior, to filter a very large dataset.

We don't necessarily want to fire the filtering after every key press, because there is no point in that if the user is still typing.

Is there any way to add a small delay, so that the filtering mechanism is only fired if the search text hasn't changed for 500 milliseconds?

Verification using DataAnnotations - Unhanded Exceptions

Hello,

I'm trying to use DataAnnotations to validate fields on my PropertyGrid (which is using AutoGeneratePropertyDefinitions). I used the instructions here as reference:

http://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/validation#validating-through-dataannotations

...and was able to get pretty far. However, when a property fails validation, I get an Unhandled Exception Error when the ValidationException is thrown. Is there a simple example project someone could provide that is able to use the PropertyGrid w/AutoGeneratePropertyDefinitions, ValidationExceptions & DataAnnotations correctly?

Thank you!

RadGridView with Bar/Pie chart embeded

Hi,

I have a RadGridView, what I need is to style the cell so that when data type is some series, it can be represented with Bar/line/Area or Pie chart.

For example, if the data type is basic types, int/string/bool etc, it just shows as is. And if the data type is series, then by default, uses Pie chart. On top of that, user can change the representation from Pie to Bar/line/Area with a drop down selection.

I hope my question is clear and this is the correct place you could help me with it.

Many thanks.

How can I initiate (raise) BeginningEdit event without of using of RadPropertyGrid.BeginEdit method?

I write WPF MVVM Prism 6 application and try to use RadPropertyGrid. How can I initiate (raise) BeginningEdit event without of using of RadPropertyGrid.BeginEdit method? I cant call BeginEdit method because my application is pure MVVM one and I don't use codebehind. If I simply change the value of the property by typing the value of selected property then BeginningEdit event is not raised. Is there a way to initiate BeginningEdit event in MVVM application without call of BeginEdit method?
