ScrollMode and custom labels

[TheGramix]

Hi guys,
I am using the radChart with the feature ScrollMode="XOnly" enabled and the Zoom disabled (EnableZoom="false").

I defined the event radChart_BeforeLayout where I would like to change the labels of the XAxis:

for( Int32 x = 0; x < radChart.PlotArea.XAxis.Item.Count; x++ )
{
    radChart.PlotArea.XAxis.Item[x].TextBlock.Text = <my value>;
}

but the labels are always 1 to N and they are also highlighted without the possibility to remove the style and change the labels :o(

I tried to remove the ScrollMode (none) and in that way it works. Where is the error? Could you help me?

I am using the last released version: 2009_Q1_402.

Many thanks in advance!
Dino

Hello TheGramix,

Due to the specifics of the chart rendering in zoom/scroll mode, you will need to perform any modifications on the axis items earlier in the page lifecycle i.e. you will need to disable the XAxis.AutoScale mechanism, add the axis items manually and modify them as appropriate in the Page_Load method like this (you need to create them manually as normally they will not be auto-generated at this stage):

protected void Page_Load(object sender, EventArgs e)
{
    radChart.PlotArea.XAxis.AutoScale = false;
    radChart.PlotArea.XAxis.AddRange(1, 12, 1);

    for (Int32 x = 0; x < radChart.PlotArea.XAxis.Items.Count; x++)
    {
        radChart.PlotArea.XAxis.Items[x].TextBlock.Text = "TEST";
    }
}
