Hi,
We have scatter plot in our client/server application where the data is aggregated on the server.
We use the scatterplot with different colored series, to product a weigthed scatterplot, where the color corresponds to the number of points with the given x-y values. (where the x and y are ranges of values instead of individual points)

When zooming/scrolling we would like to implement custom logic instead of the default zoom/sort. (to actually go back to the server and recalculate a more precice set)

During design we ran into 2 issues.
1. When Zomming on both X and Y Axis using the normal zoom function you would not get the exact zoom you would expect.

We then changed to the application to only Zoom on the X-Axis, with both Autogenerates and non autogenerated X-Axis.
We tried implementing the ZoomSettings_OnPropertyChanged, but we are unable to recalculate the actual values.

ChartArea.AxisX.ActualMinValue + (ChartArea.AxisX.ActualRange * ChartArea.ZoomScrollSettingsX.RangeStart)
ChartArea.AxisX.ActualMinValue + (ChartArea.AxisX.ActualRange * ChartArea.ZoomScrollSettingsX.RangeEnd)

Do not match the visual selection of the Zoom. We have an Amount Range on the XAxis, ranging from -2 mil, to 8 mil, selecting -0.5 mil to 1 mil, gives +1.2 mil to 1.4 mil give or take.
We even sometimes got a RangeEnd greater then 1 ?

2. Since we do our own zooming, is there a way to cancel the Client Zoom,
resetting the RangeStart&RangeEnd to 1 fires off the OnPropertyChanged Event again.

I think we are overlooking sometimes, so your help would be appriciated.

Hello Telerik Team,
I am new to Telerik. we are upgrading the project to 2011 version. In the RadGridview we have a date column display. It was working fine in the 2009 version. Now it is displaying the date with default time 12:00. How do I take out the time part and display only the date.
I have used the  DataFormatString = "{0: mm/dd/yyyy}. I could see the format change in the result. But the months are always showing 00 for all the row. What is the correct syntax? I tried this format DataFormatString = {mm/dd/yyyy} , getting error in the page load itself.

Hi,

Base on this example:

http://www.telerik.com/community/code-library/wpf/gridview/radgridview-print-and-print-preview.aspx

I made a custom reporting service for our home application needs. I installed 2010 Q3 SP1 Telerik new controls, and I steel have problem with this specific line:

element.Measure(new Size(double.PositiveInfinity, double.PositiveInfinity));

 

When the grids as too much rows (3000 can go over 300 000) that throw a out of memories exceptions in the print preview. I read a couple of article on Telerik forum that said that this issue was supposed to be fixed in Q3…  and can be cause by GridViewRowInfo objects which occupy most of the memory…

Can you please help me with that?

Hi,

I have a custom column which is a user control inheriting from GridViewColumn and has two button (add row, and remove row) basically to allow users who relay to keyboard only for data entry to tab through the row cells until the reach the last column and then have the ability to add a new row and go one with the data entry.

The problem is the tabbing order is not consistent, for example, when the user is row 4 and they are tabbing in though data bound rows, when it comes to the button Colum, it the button on the first row that gets the focus (not the same 4th row).

 

Any advice?

I am using Telerik version 2011.2.712.40
and used SolidColorBrush in ChartDefaultView.
but i want to remove Gradient from filled color.

I want to allow the user to drag the pinpoint on the map and change its location. Is this possible with RadMap if so then how?

A sample of what I want can be seen here http://code.google.com/apis/maps/documentation/javascript/v2/examples/marker-drag.html
