Hİ,

I am using a custom connection for a special purpose and want to use MVVM. But I do not know how to create custom connection instance when using MVVM. Because it needs to be created and added to the diagram instance not the graphsource. Graphsource have AddLink method but it do not take RadDiagramConnection. Can you help me to find a way to use that Custom Connection class?
Thank you,
Sarper

Upon clicking "Click here to add new row", how to display default custom field values?

Hello, I would like to enquire on the scenario as per title. I have already managed to set the values, just that the grid didn't display these values to the user. In other words, when I click "Click here to add new row", the fields are displayed as all blank (or for int column, the value is 0). But my codes do work at the back end - if the user press enter without modifying anything, the custom values I set will be added to the database. So how can I let the user see the custom default values upon clicking "Click here to add new row"? Below is the code I have, which work perfectly back-end, but didn't display to user.

private void GridCommsItem_OnPreparingCellForEdit(object sender, GridViewPreparingCellForEditEventArgs e)

{

((CommsItem)e.Row.DataContext).Status = "Store";

((CommsItem)e.Row.DataContext).Quantity = 1;

GridView keyboard navigation with groups and row details

Hi,

I have a requirement here to support ALL operations that are possible with mouse also with keyboard.
This means that the user must be able to expand all things by keyboard only.

Now I have groups in the grid view and under the groups there are rows with cells from the GridViewToggleRowDetailsColumn.
So the groups are expandable/collapseable and the rows also.

My question is: How can I navigate to the the toggle buttons of the group header and the row details column to toggle them by keyboard only?

I have subclassed already the DefaultKeyboardCommandProvider to get more control over the navigation commands. But the commands just leave out the group headers and the GridViewToggleRowDetailsColumn is leaved out while the previous row is in edit mode and a TAB key is pressed (MoveNext command is executed).

I need a tab stop on both kinds of toggle buttons. What is the best way to achieve this?

Thanks

Format Decimal Value & Export Data

Hello Telerik-Team,

i tried the Pivot Grid and it ist really nice and easy to use.

But I have two questions:

1. Is there any possibility to use different currencies when formatting a decimal value? When I use "C" in "StringFormat" my current culture is used...

2. Can i export the data that is displayed in the control to use in excel or to print?

Thanks for your help.

Connection overlap another connection

hey guys,

i looked at your demo and saw the TableShape example and asked myself, if it is possible that the connections do not overlap (line on line) each other when they are in the same direction (horizontal, vertical)? Because when i will follow one connection with my eyes it is not really comfortable when two or more connections are looking like they are the same.

Get point in current page

OK, I've searched through the objects pretty thoroughly, and can't seem to find a solution to this problem. I am trying to retrieve the point (X Y coordinates) within the current page where a mouse event fires (in this case, mouse up event)

I can get the screen coordinates, and from that the coordinates within the control, but I'm interested in returning the Point within the actual page being clicked on. Any hints?
