I have the following code:

C#

bool comparedResults = true;
            TextBox txtAddFROMKMREAD = (TextBox)GRDTech.FooterRow.FindControl("txtAddFROMKMREAD");
            DropDownList drpPlateNum = (DropDownList)Default._def.GRDTech.FooterRow.FindControl("drpPlateNum");
            int readDepartureKM = Convert.ToInt32(txtAddFROMKMREAD.Text);

            TextBox txtAddTOKMREADING = (TextBox)Default._def.GRDTech.FooterRow.FindControl("txtAddTOKMREADING");

            int arrivalKMreading = Convert.ToInt32(txtAddTOKMREADING.Text);


            comparedResults = (arrivalKMreading < readDepartureKM);

C#

int readDepartureKM = Convert.ToInt32(txtAddFROMKMREAD.Text);

keeps on giving me invalid string input.
the error is raised when I click on the update button, but when I insert it to the database it works perfectly...

when converting a string to DateTime, parse the string to take the date before putting each variable into the DateTime object

Make sure your method arguments are in the right format

I have no idea why the error is DatTime?
