Hi John,

Kindly check what value you are getting in that, set break point and check and let me know the value.

Hi John,

Modify the below code,

y[i] =convert.toDecimal(dt.Rows[i][1].ToString("0000000000.00"));

Ramesh thanks, i have changed the code to what you have posted ..the error on the Data=y is now gone but there is an error here y[i] =Convert.ToDecimal(dt.Rows[i][1].ToString(".00")); at .Tostring which says no overload for method ToString takes 1 arguments..kindly help

Hi John,
Please try the below code,
string[] x = new string[dt.Rows.Count];

decimal[] y = new decimal[dt.Rows.Count];

for (int i = 0; i
{
x[i] = dt.Rows[i][0].ToString();
y[i] =convert.toDecimal(dt.Rows[i][1].ToString(".00"));
}

@ Ramesh , i have changed as you suggested but am getting the error here decimal[] y = new decimal[dt.Rows.Count];

that " the local variable named y is already defined in this scope"

Hi John,

Just make some changes in your code,

decimal[] y = new decimal[dt.Rows.Count];

BarChart1.Series.Add(new AjaxControlToolkit.BarChartSeries { Data = y});

value Data=y expecting array of decimal value.
