How to change color of gridview row?

Hello 


Please check below code and write in row bound

protected void grdDoc _RowDataBound(object sender, GridViewRowEventArgs e)
{
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
if ((string.IsNullOrEmpty(e.Row.Cells[3].Text) != true) ||
(e.Row.Cells[3].Text != " "))
{
Char result = Convert.ToInt32(e.Row.Cells[3].Text);
if (result == 'Y') e.Row.BackColor = System.Drawing.Color.Aqua;
else if (result =='N') e.Row.BackColor = System.Drawing.Color.Cornsilk;
}
}
}
}

In that cell I have date & this date I want to compare with sysdate
If this date is greater than sysdate then the color of row will be change

Can you tell what's the exact content of the cell "e.Row.Cells[8].Text"? So that we can narrow down and possible to fix the issue quicker.

It can't find the required date from gridview. I'm trying but it will giving same error again
Any another method is their for that ?

Hello


For conver into datetime use like below

DateTime dt = DateTime.ParseExact(dateString, "ddMMyyyy",
CultureInfo.InvariantCulture);
dt.ToString("yyyyMMdd");

and check if text empty do not parse

ya, it will give error like "CS1502: The best overloaded method match for 'string.ToString(System.IFormatProvider)' has some invalid arguments"

So how to solve this error?

Hello


Can you please check,is cell text coming blank ? If so it will give error.

check your cell's 8th column

or
if (Convert.ToDateTime(e.Row.Cells[8].Text.tostring("dd/mm/yyyy")) < DateTime.Now.tostring("dd/mm/yyyy"))
{}

How to capture record insert date?
I'm using following code :

if (e.Row.RowType == DataControlRowType.DataRow) 
        {
            if (Convert.ToDateTime(e.Row.Cells[8].Text) < DateTime.Now)
            {
                e.Row.BackColor = Color.Red;
                e.Row.ForeColor = Color.White;
            }
        }

but it will give error like "String was not recognized as a valid DateTime."

So what can I do ?

use
   e.Row.BackColor = Drawing.Color.red

on row databound

for 4th day check if day diff (system date and record insert date)>=4
then

e.Row.BackColor = Drawing.Color.red
