Hi,
I had created a dynamic chart control in VS 2010. On click of 1 chart (Piechart)other chart should load.
Here chart is the 1st chart shown.But on click of this chart event is not firing.
So I have
{
base.OnPreRender(e);
Chart chrt = new Chart();
chrt.Click += new ImageMapEventHandler(chrt_click);
}
protected void chrt_click(object sender, ImageMapEventArgs args)
{
int sliceindex = int.Parse(args.PostBackValue);
}
protected void btnViewChart_Click(object sender, EventArgs e)
{
BuildPieChart(words);
}
protected void BuildPieChart(string[] strRig)
{
try
{
Chart chrt = new Chart();
chrt.Visible = true;
//chrt.Click += new ImageMapEventHandler(chrt_click);
//chk.CheckedChanged += txtChanged;
chrt.Series.Add("consumption");
chrt.Legends.Add("TestLegend");
str="";
foreach (string value in strRig)
{
str += value + ",";
}
strRigString = str.Remove(str.Length-1);
strRemove = strRigString.Remove(strRigString.Length - 1, 1);
strRigToPass = strRemove = strRemove.Remove(0, 1);
// Response.Write(str);
DataTable dt = new DataTable();
DateTime frmDate = DateTime.Parse(txtDate.Text.Trim());
String strfrmDate = frmDate.ToString("dd/MM/YYYY");
DateTime tDate = DateTime.Parse(toDate.Text.Trim());
String strtoDate = tDate.ToString("dd/MM/YYYY");
if (strfrmDate.Trim() == strtoDate.Trim())
{
//query = string.Format("select c_department, siteid,CAST(SUM(linecost) as decimal (8,1))As Consumption from matusetrans , item where item.itemnum=matusetrans.itemnum and item.capitalized=0 and matusetrans.storeloc not like ('%VRPRJ%') and matusetrans.transdate='" + txtDate.Text.Trim() + "'and matusetrans.transdate='" + toDate.Text.Trim() + "' and matusetrans.siteid='" + ddlSite.SelectedItem.Text.Trim() + "' group by matusetrans.c_department, matusetrans.siteid, matusetrans.storeloc order by matusetrans.siteid, matusetrans.storeloc, matusetrans.c_department ");

But this is not called on chart click . Any idea?
