[Solved] ASP.Net Error: Operator '<' cannot be applied to operands of type 'string' and 'int'

kankon says:

if (Label_day.Text < 15)

{

    gvFiles.FooterRow.Cells[3].Text = ("Total", 35 - Convert.ToInt32(dt.Compute("Sum(totalva)", ""))).ToString();

}

else if (Label_day.Text  20)

{

    gvFiles.FooterRow.Cells[3].Text = ("Total", 45 - Convert.ToInt32(dt.Compute("Sum(totalva)", ""))).ToString();

}

Replace with below code.

if (Convert.ToInt32(Label_day.Text) < 15)
{
    gvFiles.FooterRow.Cells[3].Text = ("Total", 35 - Convert.ToInt32(dt.Compute("Sum(totalva)", ""))).ToString();
}
else if (Convert.ToInt32(Label_day.Text) >= 15)
{
    gvFiles.FooterRow.Cells[3].Text = ("Total", 45 - Convert.ToInt32(dt.Compute("Sum(totalva)", ""))).ToString();
}
