I'm working on a multi-tab WinApp that will contain about 20 charts and 50 chart series of data that the user can select from. The data will be coming in via UDP at about a 16 Hertz data rate. I need some "best practices" type of advice for creating a smooth user experience using the Telerik RadChart. For instance, with this number of charts, how many data points per chart can I realistically display?

Thanks,

Chart (obsolete as of Q1 2013)

Overriding Windows 7 theme

I want the document window tab headers to look the same way as they look in the default layout or as in Office 2010. What is it that I need to change in the theme?

Also the gridview does not show any row borders at first, but then renders the borders when mouse hovers past the rows. How do I get the borders to be shown as a default behaviour. I have set DrawBorder to true

Thanks

[Solved] Add 2 buttons dynamically and set there visibility by checking the values of another column in grdi view

hi all,

i am using telerik grid view in windows form application. i needed to to add two buttons in the command column dynamically. and then according to the values of some other column i can make any of the button invisible.
i was able to add a column with 2 buttons. but when i made any of them invisible it shows unexpected behavior. the adding of buttons and making them visible or not, only works fine for the rows that are present on the current display screen. if i scroll down then it makes the button invisible or visible in other rows. i am stuck. please help.
i am using function

private void radGWOrderSelection_CreateCell(object sender, GridViewCreateCellEventArgs e)

{

if (e.Column.Name == "Replace")

{

GridViewCommandColumn dataColumn = (GridViewCommandColumn)e.Column;

if (e.Row is GridDataRowElement && dataColumn != null)

{

CustomGridDataCell cell = new CustomGridDataCell(e.Column, e.Row);

e.CellType = typeof(CustomGridDataCell);

e.CellElement = cell;

cell.ButtonOne.Visibility = ElementVisibility.Hidden;

cell.ButtonClick += new EventHandler(cell_ButtonClick);

cell.ButtonOne.Visibility = ElementVisibility.Hidden;

cell.ButtonClick += new EventHandler(cell_ButtonClick);

cell.CommandButton.Dispose();

}

if i put a breakpoint it only executes 14 times which is the number of visible rows in the grid.

there is also a custom class CustomGridDataCell

MulitColumn ComboBox scrolls when clicking on an item

When I click on my RadMultiColumnComboBox, the dropdown opens displaying my grid of items. There's about 100 or so items, so the list is scrollable. Occasionally when clicking an item, for some reason the scroll position changes. This is causing a different item to be selected since it looks like an item gets selected when the click releases. So if the grid is displaying items 1 through 5,
1
2
3
4
5
...
I'll click on item 3, the scroll position will slightly shift down so now my mouse is over item 4. So by the time the click is released, it selects item 4. Does that make sense? I was wondering if anyone has come across a similar issue before I try extracting code to post.

Thanks,
Jason

I've added code to illustrate the problem. When I click on the item Code = 2, it selects Code = 3.

Wrong Selected Window when Loading from Xml

Hi the Telerik Team,

There is a error with the RadDock when loading layout from XML file.
When you load the layout from an XML file, the selected index of a DocumentContainer or a ToolTabStrip is incorrect. The last one is always selected, even if the SelectedIndex is the first.
You can easily reproduce this bug with the demo application on Dock / Serialization:
- Add a tool window to the same area as Tool Window 2
- Select the first window of the ToolTabStrip (Tool Window 4)
- Save the layout
- If you open the layout file in an editor, you can see that the ToolTabStrip's SelectedIndex is 0 (correct).
- Remove all windows
- Load the layout file
- The Tool Window 2 is selected instead of the Tool Window 4.

Thank you,

Regards

Dock
