Inadequate grid data retrieval (This problem arises randomly)

Question

Inadequate grid data retrieval (This problem arises randomly)

During the process of loading data in a grid on our production server, I encountered a script error at the bottom left corner of the page. Interestingly, this error only occurs on the production server and works perfectly fine on the local server.

Here are the details of the webpage error:

User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; BTRS123646; Embedded Web Browser from: ; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.648; .NET CLR 3.5.21022; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E) Timestamp: Tue, 9 Oct 2012 12:11:23 UTC

Message: Unterminated string constant Line: 111115201 Char: 187 Code: 0

URI: XYXZ/MYApp/MyPage.aspx

Below is the code snippet responsible for binding data to the grid:

 try
            {
                // C# code goes here
            }
catch(Exception ex)
{
    return;
}
finally
{
    // Close connection if open
}

If you're wondering how to identify the line number within your C# code and how to fix it, please seek assistance. We're here to help!

One possible solution is to insert a BindingSource in the middle, similar to this: Control.DataSource = new BindingSource(data, "");

After much effort and troubleshooting, I have finally managed to solve the issue at hand.

To track down the root cause, I enabled script debugging and utilized the Fiddler 2 tool to pinpoint the problem. It turns out that there was an error occurring during date parsing.

In order to address this issue, I created a method for datetime conversion:

public static bool ValidateDate(string txtDate, string sDateFormat, ref string sErrMsg, ref DateTime dtDate)
{
    if (txtDate == "")
    {
        sErrMsg = "Please Enter Date";
        return false;
    }
    else
    {
        System.Globalization.DateTimeFormatInfo dateInfo = new System.Globalization.DateTimeFormatInfo();
        dateInfo.ShortDatePattern = sDateFormat;

        try
        {
            dtDate = Convert.ToDateTime(txtDate, dateInfo);
            return true;
        }
        catch
        {
            sErrMsg = "Please Enter Date In Correct Format";
            return false;
        }
    }
}

I then applied this method in the following manner:

string errMsg = string.Empty;
Boolean IsFromDateValid = false;
DateTime fromDate = new DateTime();
IsFromDateValid = ValidateDate(wdpfrom.Text.Trim(), "dd/MM/yyyy", ref errMsg, ref fromDate);
if (IsFromDateValid == false)
{
    ShowMessage(errMsg);
    return;
}
Boolean IsToDateValid = false;
DateTime toDate = new DateTime();
IsToDateValid = ValidateDate(wdpTo.Text.Trim(), "dd/MM/yyyy", ref errMsg, ref toDate);
if (IsToDateValid == false)
{
    ShowMessage(errMsg);
    return;
}
else
{
    TimeSpan ts = new TimeSpan(23, 59, 59);
    toDate = toDate.Add(ts);
}

Finally, I passed the parameters to the stored procedure like so:

cmdGetPost.Parameters.AddWithValue("@dateFrom", fromDate);
cmdGetPost.Parameters.AddWithValue("@dateTo", toDate);
