Setting the value of start tick manually

Hello,

On the x axis, I have a range of values from 1/2001 to 1/2010 where I have a value for each month. I need to have ticks every 4 months (MajorTickInterval = 4 is working fine), but I need to have ticks starting from 3/2001, so I will have tick on each 3/xxxx, 7/xxxx, 11/xxxx month. How to achieve this?

Thanks in advance

Column 'ID' does not belong to table.

Still happens. With no end in sight.

Tried different datasource calls. Still happens. What you say is right, is wrong. BUGS BUGS BUGS. Zero fixes. Please stop selling a product that does not work and which you do not care to develop.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I can't wait to move off your controls and end the continuous frustration of poor development.

Begin/End Update STILL NOT WORKING!!!

If I am setting :
mygrid.TableElement.BeginUpdate()
mygrid.CurrentRow = Nothing
mygrid.TableElement.EndUpdate()

WHY IS CELLFORMATTING BEING CALLED ON CURRENT ROW???!?!?!?!?

Oh, that's right...I refuse to pay support to companies that don't know how to make a usable product.
I think the only solution to save my sanity is GET AWAY FROM TELERIK WINFORMS CONTROLS!
Nothing works as it should...NOTHING!

MajorStep changing on y linear axis when zooming in

Hello,

I have issues with major step on the y linearAxis changing when zooming in. Generated ticks and corresponding grid is displayed correctly only in the case when whole chart is shown (zoom = 1). When I zoom in, interval between ticks on y axis is changed. Please note that I have applied similar logic on the zoom event on the x axis and it's working fine. However, it seems that MajorStep on the linear y axis cannot be changed in the same like MajorTickInterval on the categorical x axis. So, how to keep interval between ticks on the y axis constant after changing the zoom settings?

Here is the code snippet I'm using:

private void View_ZoomChanged(object sender, EventArgs e)

{

var horizontalAxis = radChartView1.Axes[0] as CategoricalAxis;

int DesiredHorizontalTickInterval = 12;

double horizontalScale = (radChartView1.View as IChartView).ZoomWidth;

int zoomWidth = (int)(horizontalScale + .5);

if (horizontalAxis.MajorTickInterval != zoomWidth * DesiredHorizontalTickInterval)

{

horizontalAxis.MajorTickInterval = zoomWidth * DesiredHorizontalTickInterval;

}

int desiredVerticalMajorStep = 7;

double verticalScale = (radChartView1.View as IChartView).ZoomHeight;

int zoomHeight = (int)(verticalScale + .5);

var yAxis = ((sender as ChartView).Axes.Last() as LinearAxis);

if (yAxis.MajorStep != zoomHeight * desiredVerticalMajorStep)

{

yAxis.MajorStep = zoomHeight * desiredVerticalMajorStep;

}

Pan and Zoom adjust based on legend drawing.

Hello,

When implementing functionality to programmatically allow user to zoom (not to cut, but zoom, being able to zoom in/out afterwards) to particular range on the x and y axis I had an issue with pan/zoom functionality.

I used radChartView1.View.Area.AreaModel.PlotArea.LayoutSlot.Width and radChartView1.View.Area.AreaModel.PlotArea.LayoutSlot.Height to get visible area inside axes because there was always a shift caused by axes titles whose size I must also be able to change dinamically. That shift isn't constant and I had to manually calculate it based on the selected font size of chart elements. This worked fine.

However, it turned out that I have an issue when chart is redrawn from the start, with the legend shown, and my calculations are performed in such a way that radChartView1.View.Area.AreaModel.PlotArea.LayoutSlot.Width doesn't consider the legend on the right which is added after I do my calculations. My question is, is there an event which is fired after the legend is added (or any event before finally drawing chart which will still allow me to call method that I'm using to change pan/zoom) so I can use PlotArea.LayoutSlot.Width in a way that it will be the width of the plotted chart area after the legend is shown (since legend will eat some of the width I calculated).

Thanks
