Bind Crystal Reports with Dataset

I am having a form where I am updating data in my gridview and that updated gridview I want to save in one of the table on Save_Button_click; after that i want to generate report(crystal) for that sorted and updated data; there I got stuck ; Thanks in advance!
here is my query:
string StrAsset = "select * from tbl_Pre_Y1_Bus1,tbl_Pre_Y1_Bus_Master1_temp where tbl_Pre_Y1_Bus1.id='" + id + "' and tbl_Pre_Y1_Bus_Master1_temp.ID='" + ID + "')";
My Code:
{
dt.Columns.Add(new System.Data.DataColumn("id", typeof(int)));
dt.Columns.Add(new System.Data.DataColumn("PartNo", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("ChallanDate", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("ChallanNo", typeof(int)));
dt.Columns.Add(new System.Data.DataColumn("sup_remark", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("sup_status", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("TMl_remark", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("Tml_status", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("Date_supp", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("Sup_ins_name", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("date_insp", typeof(string)));
dt.Columns.Add(new System.Data.DataColumn("Inspectorname", typeof(string)));
}
for (int i = 0; i < DSAsset.Tables[0].Rows.Count; i++)
{
dr = dt.NewRow();
dr[12] = DSAsset.Tables[0].Rows[i]["sup_remark"].ToString();
dr[13] = DSAsset.Tables[0].Rows[i]["sup_status"].ToString();
dr[14] = DSAsset.Tables[0].Rows[i]["TMl_remark"].ToString();
dr[15] = DSAsset.Tables[0].Rows[i]["Tml_status"].ToString();
dr[16] = DSAsset.Tables[0].Rows[i]["Date_supp"].ToString();
dr[17] = DSAsset.Tables[0].Rows[i]["Sup_ins_name"].ToString();
dr[18] = DSAsset.Tables[0].Rows[i]["date_insp"].ToString();
dr[19] = DSAsset.Tables[0].Rows[i]["Inspectorname"].ToString();
dt.Rows.Add(dr);
dt.AcceptChanges();

value getting changed during SqlBulkCopy

I am trying to upload some data from csv file to sql server using SqlBulkCopy
The problem here is that the values get changed automatically
eg 0.9824 becomes 0.982400000095367
Here is the code that I am using
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(strConnectionString, SqlBulkCopyOptions.FireTriggers))
{
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("dt", typeof(DateTime)));
dt.Columns.Add(new DataColumn("wreb", typeof(string)));
dt.Columns.Add(new DataColumn("zid", typeof(int)));
dt.Columns.Add(new DataColumn("zone_name", typeof(string)));
dt.Columns.Add(new DataColumn("region", typeof(string)));
dt.Columns.Add(new DataColumn("iloss", typeof(float)));
dt.Columns.Add(new DataColumn("dloss", typeof(float)));
for (int i = 0; i < DataDS.Tables[0].Rows.Count; i++)
{
DataRow myDr = dt.NewRow();
myDr["dt"] = DateTime.ParseExact(DataDS.Tables[0].Rows[i]["dt"].ToString(), "d/M/yyyy", null);
myDr["wreb"] = DataDS.Tables[0].Rows[i]["wreb"].ToString();
myDr["zid"] = DataDS.Tables[0].Rows[i]["zid"].ToString();
myDr["zone_name"] = DataDS.Tables[0].Rows[i]["zone_name"].ToString();
myDr["region"] = DataDS.Tables[0].Rows[i]["region"].ToString();
myDr["iloss"] = DataDS.Tables[0].Rows[i]["iloss"].ToString();
myDr["dloss"] = DataDS.Tables[0].Rows[i]["dloss"].ToString();
dt.Rows.Add(myDr);
myDr = null;
}
bulkCopy.BulkCopyTimeout = 0;
bulkCopy.ColumnMappings.Add("dt", "Zdate");
bulkCopy.ColumnMappings.Add("wreb", "Entity");
bulkCopy.ColumnMappings.Add("zid", "ZoneID");
bulkCopy.ColumnMappings.Add("zone_name", "Zone_Name");
bulkCopy.ColumnMappings.Add("region", "region");
bulkCopy.ColumnMappings.Add("iloss", "iloss");
bulkCopy.ColumnMappings.Add("dloss", "dloss");
bulkCopy.DestinationTableName = "tbl_zloss";
bulkCopy.WriteToServer(dt);
}

Looks like you're using float which is an imprecise datatype.
Use decimal to get exact values. Precision and scale depend on your data

how to split date & time from xml

i have an XML file which contain date & time like this
<date>3/24/2014</date>
<time>9:00 AM</time>
</playdate>
i store this data in a data set & want to add in data table. i write this code for getting data
DataRow dr = dt.NewRow();
dr["StartDate"] = ds.Tables[0].Rows[i][1].ToString();
dr["StartTime"] = ds.Tables[0].Rows[i][1].ToString();
But the problem is when i export data in excel file i got both date & time in excel file in same column. i want date in my StartDate & time in StartTime . how can i split XML data
EDIT
string url = #"c:\temp\TestXML.xml";
StreamReader reader = new StreamReader(url);
string input = reader.ReadToEnd();
input = input.Trim();
input = input.Replace("- <", " <");
input = input.Replace(" & ", " & ");
input = input.Replace("W&W", "W&W");
input = input.Replace("", "
");
int userid = 0;
int j = 1;
try
{
DataSet ds = new DataSet();
ds.ReadXml(new StringReader(input));

}

gvXmlData.DataBind();

try with DateTime.ParseExact
string cellValue = "3/31/2014 9:00:00 AM";// this can be a cell value from excel file like ds.Tables[0].Rows[i][1].ToString()
DateTime date = DateTime.ParseExact(
cellValue,
"M/dd/yyyy h:mm:ss tt",
CultureInfo.InvariantCulture);
string startDate = date.ToString("M/dd/yyyy");
string startTime = date.ToString("h:mm:ss tt");

You are accessing same cell value in both StartDate and StartTime.
Most probably next cell should give you time value.
Also you can format date time same as specified in XML e.g. (mm/dd/YYYY)
Same goes with time hours minutes and seconds.
see code example here:
string sDate = ds.Tables[0].Rows[i][0].ToString();
string sTime = ds.Tables[0].Rows[i][1].ToString();
DateTime dDateTime;
DataRow dr = dt.NewRow();
//cond: for checking the datetime parsing
if (DateTime.TryParseExact(sDate, "M/dd/yyyy", CultureInfo.InvariantCulture, DateTimeStyles.None, out dDateTime))
{
//sDate = dDateTime.ToString("M/dd/yyyy");
//dr["StartDate"] = sDate;
dr["StartDate"] = dDateTime;
}
//cond: for checking the datetime parsing
if (DateTime.TryParseExact(sTime, "hh:mm:ss", CultureInfo.InvariantCulture, DateTimeStyles.None, out dDateTime))
{
//sTime = dDateTime.ToString("h:mm:ss");
//dr["StartTime"] = sTime;
dr["StartTime"] = dDateTime;
}

Data Table Getting error when i add data rows[]

DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Date", typeof(String)));
dt.Columns.Add(new DataColumn("Time", typeof(String)));
dt.Columns.Add(new DataColumn("Function", typeof(String)));
dt.Columns.Add(new DataColumn("Log Level", typeof(String)));
dt.Columns.Add(new DataColumn("Message", typeof(String)));
When i query DataTable then get DataRows[]
DataRow[] result = dt.Select("Function ='" + strfunction + "'");
Now i want to add that result in DataTable
dt.Rows.Add(result);
But i am getting error
Input array is longer than the number of columns in this table.

try this
foreach (DataRow row in result)
dt.Rows.Add(row);

DataRowCollection.Add() has two overloads:
Add(DatarRow row);
Add(params object[] values);
The one you are currently using is Add(params object[] values); since you are passing an array of a class with base class of object. So you are searching in the same table, getting the same number of columns indeed, but the problem is that; you expect each element of the array to be inserted as a DataRow, but there is only one row inserted and each element of the array DataRow[] result is assigned for columns
With:
dt.Rows.Add(new object[] { "Date", "Time", "a", "Log Level", "Message" });
DataRow[] result = dt.Select("Function ='a'");
foreach (DataRow r in dt.Rows)
{
/* Log r or inpect */
}
No exception was thrown in my test because the result array had only 1 element (as search result).
If i have more then 5 elements in result; since i can't insert 6 column values in a 5 column table it will throw exception.
And the correct way to do it is interating search results array and adding a new row for each array element; using DataRow.ItemArray property
You can try the following which worked for me:
DataRow[] result = dt.Select("Function ='" + strfunction + "'");
foreach (DataRow r in result)
{
dt.Rows.Add(r.ItemArray);
}

Instead of directly adding the DataRow to the DataTable, how about creating a foreach loop and creating a separate DataRow from the DataTable, filling the data and adding it into the DataTable. For example:
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("Date", typeof(String)));
dt.Columns.Add(new DataColumn("Time", typeof(String)));
dt.Columns.Add(new DataColumn("Function", typeof(String)));
dt.Columns.Add(new DataColumn("Log Level", typeof(String)));
dt.Columns.Add(new DataColumn("Message", typeof(String)));
//Dummy data added
DataRow dr = dt.NewRow();
dr[0] = "aa";
dr[1] = "bb";
dr[2] = "cc";
dr[3] = "dd";
dr[4] = "ee";
dt.Rows.Add(dr);
string strfunction = "cc";
DataRow[] result = dt.Select("Function ='" + strfunction + "'");
//Initialize Datarow here. I am using the one which is defined above
dr = null;
foreach (var item in result)
{
dr = dt.NewRow();
dr[0] = item[0];
dr[1] = item[1];
dr[2] = item[2];
dr[3] = item[3];
dr[4] = item[4];
dt.Rows.Add(dr);
}
Hope this helps.

Sqlbulkcopy doesn't seem to work for me

I have created a datatable and trying to insert that datatable through SqlBulkCopy but somehow it doesn't seem to work for me....
I got the error,
The given value of type DateTime from the data source cannot be converted
to type decimal of the specified target column.
My Datasource is,
DataTable dt = new DataTable();
dt.Columns.Add(new DataColumn("EmpId", typeof(Int64)));
dt.Columns.Add(new DataColumn("FromDate", typeof(DateTime)));
dt.Columns.Add(new DataColumn("ToDate", typeof(DateTime)));
dt.Columns.Add(new DataColumn("DaysPresent", typeof(decimal)));
dt.Columns.Add(new DataColumn("OpeningAdvance", typeof(double)));
dt.Columns.Add(new DataColumn("AdvanceDeducted", typeof(double)));
dt.Columns.Add(new DataColumn("RemainingAdvance", typeof(double)));
dt.Columns.Add(new DataColumn("SalaryGiven", typeof(double)));
dt.Columns.Add(new DataColumn("CreatedDate", typeof(DateTime)));
foreach (GridViewRow row in gridEmployee.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
DataRow dr = dt.NewRow();
dr["EmpId"] = Convert.ToInt64(((HiddenField)row.Cells[0].FindControl("HiddenId")).Value);
dr["FromDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(fromdate[1].ToString()) + '/' + fromdate[0].ToString() + '/' + fromdate[2].ToString());
dr["ToDate"] = Convert.ToDateTime(GetMonthNumberFromAbbreviation(todate[1].ToString()) + '/' + todate[0].ToString() + '/' + todate[2].ToString());
dr["DaysPresent"] = Convert.ToDecimal(((TextBox)row.Cells[3].FindControl("TxtDaysPresent")).Text);
dr["OpeningAdvance"] = Convert.ToDouble(((TextBox)row.Cells[4].FindControl("txtOpeningAdv")).Text);
dr["AdvanceDeducted"] = Convert.ToDouble(((TextBox)row.Cells[5].FindControl("TxtAdvanceDeducted")).Text);
dr["RemainingAdvance"] = Convert.ToDouble(((TextBox)row.Cells[6].FindControl("TxtClosingAdvance")).Text);
dr["SalaryGiven"] = Convert.ToDouble(((TextBox)row.Cells[7].FindControl("TxtSalary")).Text);
dr["CreatedDate"] = Convert.ToDateTime(System.DateTime.Now.ToString());
dt.Rows.Add(dr);
}
}
SqlBulkCopy sbc = new SqlBulkCopy(connectionString);
sbc.DestinationTableName = "SalaryDetails";
sbc.WriteToServer(dt);
sbc.Close();
And my destination Table looks like this,
alt text http://img231.imageshack.us/img231/5448/mytable.jpg

You need to specify a column mapping, as you don't have the same number of columns in the DataTable and the destination table.
You can do it like this:
sbc.ColumnMappings.Add("EmpId", "EmpId");
sbc.ColumnMappings.Add("FromDate", "FromDate");
// and so on, with the rest of the columns; and after that comes
sbc.WriteToServer(dt);
sbc.Close();
