I am working in .Net Charts. I am trying to generate a Column chart. I am having two rows in my dataset. Here is my code.
DataTable DT1 = new DataTable();
DT1 = chartViewSummaryList;
DataView DV = DT1.DefaultView;
DV.ToTable(false, new string[] { "REVENUE_TOTAL", "WEEK_END_DATE" });
DataSet ds = new DataSet();
ds.Tables.Add(DT1.Copy());
ds.Tables[0].Rows[0]["MARGIN"] = "0";
ds.Tables[0].Rows[0]["REVENUE_TOTAL"] = "3776169.61";
ds.Tables[0].Rows[0]["MARGIN_PCT"] = "0";
ds.Tables[0].Rows[0]["VISIT_REVENUE_AVG"] = "29.28";
ds.Tables[0].Rows[0]["VISIT_COUNT"] = "614041";
ds.Tables[0].Rows[0]["REVENUE_SALE"] = "1840387.18";
ds.Tables[0].Rows[0]["REVENUE_REGULAR"] = "1935782.43";
ds.Tables[0].Rows[0]["WEEK_END_DATE"] = "1/1/2012 12:00:00 AM";
ds.Tables[0].Rows.Add();
ds.Tables[0].Rows[1]["MARGIN"] = "1";
ds.Tables[0].Rows[1]["REVENUE_TOTAL"] = "5776169.61";
ds.Tables[0].Rows[1]["MARGIN_PCT"] = "0";
ds.Tables[0].Rows[1]["VISIT_REVENUE_AVG"] = "49.28";
ds.Tables[0].Rows[1]["VISIT_COUNT"] = "814041";
ds.Tables[0].Rows[1]["REVENUE_SALE"] = "3840387.18";
ds.Tables[0].Rows[1]["REVENUE_REGULAR"] = "3935782.43";
ds.Tables[0].Rows[1]["WEEK_END_DATE"] = "1/1/2012 12:00:00 AM";
Chart1.DataSource = ds;
for (int i = 0; i < ds.Tables[0].Rows.Count; i++)
{
Chart1.Titles.Add(storeLevelCaption).Font = new System.Drawing.Font("Verdana", 11, FontStyle.Bold);
Chart1.ChartAreas["ChartArea1"].AxisX.Title = "Weeks";
Chart1.ChartAreas["ChartArea1"].AxisX.TitleFont = new System.Drawing.Font("Verdana", 10, FontStyle.Bold);
Chart1.ChartAreas["ChartArea1"].AxisX.LabelStyle.Font = new Font(new FontFamily("Verdana"), 7.25F, FontStyle.Bold);
string series = "Series" + i;
Chart1.Series.Add(series);
Chart1.Series[series].ChartType = System.Web.UI.DataVisualization.Charting.SeriesChartType.Column;
Chart1.Series[series].XValueMember = "WEEK_END_DATE";
Chart1.ChartAreas["ChartArea1"].AxisX.MajorGrid.Enabled = false;
Color color = System.Drawing.ColorTranslator.FromHtml("#B93B8F");
Chart1.Series[series].Color = color;
Chart1.ChartAreas["ChartArea1"].AxisY.Title = "Total Revenue";
Chart1.ChartAreas["ChartArea1"].AxisY.TitleFont = new System.Drawing.Font("Verdana", 10, FontStyle.Bold);
Chart1.ChartAreas["ChartArea1"].AxisY.LabelStyle.Font = new Font(new FontFamily("Verdana"), 7.25F, FontStyle.Bold);
Chart1.Series[series].YValueMembers = "REVENUE_TOTAL";
Chart1.ChartAreas["ChartArea1"].AxisY.MajorGrid.Enabled = false;
Chart1.Series[series].ToolTip = "Total Revenue ($) , " + ds.Tables[0].Rows[i]["WEEK_END_DATE"].ToString() + " , " + ds.Tables[0].Rows[i]["REVENUE_TOTAL"].ToString();
Chart1.Series[series].Font = new Font(new FontFamily("Verdana"), 7.25F, FontStyle.Bold);
//Chart1.Series[series].Name = "Total Revenue";
}
Chart1.ChartAreas[0].AxisY.Interval = 1;
Chart1.DataBind();
I am getting the chart, where two column combined together and displayed as one column. Where i had gone wrong...
I can't reproduce your problem using the WinForm charting assemblies. However you may want to try using distinct dates since they are bound to your X values.
ds.Tables[0].Rows[0]["WEEK_END_DATE"] = "1/1/2012 12:00:00 AM";
ds.Tables[0].Rows[1]["WEEK_END_DATE"] = "8/1/2012 12:00:00 AM"; // a different date
FYI, I changed your code minimaly
// DT1 = chartViewSummaryList;
// replace unknown object with this code
DT1.Columns.Add(new DataColumn("MARGIN"));
DT1.Columns.Add(new DataColumn("REVENUE_TOTAL"));
DT1.Columns.Add(new DataColumn("MARGIN_PCT"));
DT1.Columns.Add(new DataColumn("VISIT_REVENUE_AVG"));
DT1.Columns.Add(new DataColumn("VISIT_COUNT"));
DT1.Columns.Add(new DataColumn("REVENUE_SALE"));
DT1.Columns.Add(new DataColumn("REVENUE_REGULAR"));
DT1.Columns.Add(new DataColumn("WEEK_END_DATE"));
and also added a row manually
ds.Tables.Add(DT1.Copy());
ds.Tables[0].Rows.Add(); // Added this
and got two columns from your plotting code.

I'm using NPOI Excel Library to generate a Excel file, in that Excel file i'm explicitly define column type for Columns like Date,String etc.
Im using the following code to achive this.
var row = sheet.CreateRow(currentNPOIRowIndex++);
for (var colIndex = 0; colIndex < exportData.Columns.Count; colIndex++)
{
ICell cell = null;
cell = row.CreateCell(colIndex);
if (exportData.Columns[colIndex].DataType == typeof(DateTime))
{
if (exportData.Rows[rowIndex][colIndex].ToString() != "")
{
cell.SetCellValue((DateTime)exportData.Rows[rowIndex][colIndex]);
cell.CellStyle = (NPOI.HSSF.UserModel.HSSFCellStyle)book.CreateCellStyle();
cell.CellStyle.DataFormat = book.CreateDataFormat().GetFormat("yyyyMMdd HH:mm:ss");
cell = null;
}
else
cell.SetCellValue(exportData.Rows[rowIndex][colIndex].ToString());
}
else
cell.SetCellValue(exportData.Rows[rowIndex][colIndex].ToString());
}
}
The above code works fine for 42 rows i.e. it correctly set the Column Type,but after 42 rows Column Type doesn't apply.
Any help will be highly appreciated.
you'll required to set default column style if you want to set column format for all cells of that column. Please see the below example from xssf format. Syntax may differ for your hssf format but it will give you idea what you are missing.
I am providing you from my working code. I am using NPOI version 2.2.1.0.
can you comment line //cell = null;
XSSFWorkbook workbook = new XSSFWorkbook();
XSSFSheet sheet = (XSSFSheet)workbook.CreateSheet("Template");
XSSFFont defaultFont = (XSSFFont)workbook.CreateFont();
defaultFont.FontHeightInPoints = (short)10;
XSSFCellStyle headerStyle = (XSSFCellStyle)workbook.CreateCellStyle();
headerStyle.WrapText = true;
XSSFCellStyle defaultStyle = (XSSFCellStyle)workbook.CreateCellStyle();
XSSFDataFormat defaultDataFormat = (XSSFDataFormat)workbook.CreateDataFormat();
defaultStyle.SetDataFormat(defaultDataFormat.GetFormat("000-000-0000"));
defaultStyle.FillBackgroundColor = IndexedColors.LightYellow.Index;
defaultStyle.FillForegroundColor = IndexedColors.LightTurquoise.Index;
defaultStyle.SetFont(defaultFont);
var row = sheet.CreateRow(0);
for (int headerCount = 0; headerCount < headers.Count(); headerCount++)
{
row.CreateCell(headerCount).SetCellValue(headers[headerCount]);
row.Cells[headerCount].CellStyle = headerStyle;
sheet.SetDefaultColumnStyle(headerCount, defaultStyle);
}
I create a column field in EPPlus like so:
// Column field[s]
var monthYrColField = pivotTable.Fields["MonthYr"];
pivotTable.ColumnFields.Add(monthYrColField);
...that displays like so (the "201509" and "201510" columns):
I want those values to display instead as "Sep 15" and "Oct 15"
In Excel Interop it's done like this:
var monthField = pvt.PivotFields("MonthYr");
monthField.Orientation = XlPivotFieldOrientation.xlColumnField;
monthField.NumberFormat = "MMM yy";
...but in EPPlus the corresponding variable (monthYrColField) has no "NumberFormat" (or "Style") member.
I tried this:
pivotTableWorksheet.Column(2).Style.Numberformat.Format = "MMM yy";
...but, while it didn't complain or wreak havoc, also did not change the vals from "201509" and "201510"
How can I change the format of my ColumnField column headings in EPPlus from "untransformed" to "MMM yy" format?
UPDATE
For VDWWD:
As you can see by the comments, there are many things related to PivotTables which don't work or are hard to get to work in EPPlus; Excel Interop is a bear (and not a teddy or a Koala, but more like a grizzly) compared to EPPlus, but as to PivotTables, it seems that EPPlus is kind of half-baked to compared to Exterop's fried-to-a-crispness.

You can use the build-in Date format YearMonthPattern. which would give september 2016 as format.
pivotTableWorksheet.Column(2).Style.Numberformat.Format = DateTimeFormatInfo.CurrentInfo.YearMonthPattern;
If you really want MMM yy as pattern, you need to overwrite the culture format:
Thread.CurrentThread.CurrentCulture = new CultureInfo("nl-NL")
{
DateTimeFormat = { YearMonthPattern = "MMM yy" }
};
pivotTableWorksheet.Column(2).Style.Numberformat.Format = DateTimeFormatInfo.CurrentInfo.YearMonthPattern;
It doesn't seem that you can set the format on the field itself. You have to access through the pivot table object:
pivotTable.DataFields[0].Format = "MMM yy";
Any formatting applied to the underlying worksheet seems to be completely ignored.
I am trying to get the filed names from 2 sharepoint lists and put them into 2 different dropdownlist on a webpart. However, there were some repeating field names in the dropdownlist. I wonder if my code is correct. or is there any other method to achieve the goal?
DataTable table = new DataTable("table");
DataColumn column;
column = new DataColumn();
column.DataType = Type.GetType("System.String");
column.ColumnName = "Title";
table.Columns.Add(column);
column = new DataColumn();
column.DataType = Type.GetType("System.String");
column.ColumnName = "Internal";
table.Columns.Add(column);
DataRow row;
foreach (SPField f in importList.Fields)
{
row = table.NewRow();
row["Title"] = f.Title;
row["Internal"] = f.InternalName;
table.Rows.Add(row);
}
ddlImport.DataSource = table;
ddlImport.DataTextField = "Title";
ddlImport.DataValueField = "Internal";
ddlImport.DataBind();
You may consider Removing hidden field
foreach (SPField f in importList.Fields)
{
if (!f.Hidden)
{
row = table.NewRow();
row["Title"] = f.Title;
row["Internal"] = f.InternalName;
table.Rows.Add(row);
}
}
I tried to read the existing excel file and copied to another path, and then i tried to insert data to the file i cloned. But I can' insert data. I don't know where I made mistake. But Here I've given my code.
Error occured in the line sheetData.InsertAt<Row>(row,++rowIndex);. Please help me out.

Before you append Row, you should mentioned the row index to the instance...
row.RowIndex = (UInt32)rowIndex++;
I am using 2 datagridview to see the data in a windows form application.
The first DGV show the products according to the ids passed to them.
On click of VIEW as of my one column in DGV1, it passes the product id to and fetch the complete records from database and show the records to the other DGV2.
this is my code:
if (dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value == (Object)"View")
{
if (con.State == ConnectionState.Closed)
{
con.Open();
}
int prod_id = Convert.ToInt16(dataGridView1.Rows[e.RowIndex].Cells[0].Value);
dataGridView2.DataSource = null;
dataGridView2.Rows.Clear();
retFindProducts = new MySqlCommand("SELECT DISTINCT tf_history.thefind_id, tf_product.product_id, tf_product.`name`, tf_product.product_url, tf_product.image_tpm, tf_product.image_thefind, tf_product.image_accuracy, (SELECT MIN(tf_h.price) FROM tf_history AS tf_h WHERE tf_h.thefind_id = tf_history.thefind_id) as price, oc_product.price AS priceTPM FROM tf_product LEFT JOIN tf_history ON tf_product.product_id = tf_history.product_id AND tf_product.thefind_id = tf_history.thefind_id LEFT JOIN oc_product ON tf_product.product_id = oc_product.product_id WHERE tf_product.product_id = #product_id", con);
historyData = new MySqlCommand("SELECT price, date from tf_history WHERE thefind_id = #thefind_id", con);
retFindProducts.CommandTimeout = 300;
historyData.CommandTimeout = 300;
retFindProducts.Parameters.AddWithValue("#product_id", prod_id);
dr = retFindProducts.ExecuteReader();
retFindProducts.Parameters.Clear();
while (dr.Read())
{
dataGridView2.Rows.Add();
long fI = Convert.ToInt64(dr["thefind_id"]);
//if (!findId.Exists(p => p.Item1 == fI))
findId.Add(new Tuple<long>(fI));
decimal findPrice = Convert.ToDecimal(dr["price"]);
decimal tpmPrice = Convert.ToDecimal(dr["priceTPM"]);
if (findPrice > tpmPrice)
{
dataGridView2.Rows[cnt].Cells[4].Style.ForeColor = Color.Green;
dataGridView2.Rows[cnt].Cells[4].Style.Font = new Font(dataGridView2.DefaultCellStyle.Font.FontFamily, 9, FontStyle.Regular);
}
else if (findPrice < tpmPrice)
{
dataGridView2.Rows[cnt].Cells[4].Style.ForeColor = Color.Red;
dataGridView2.Rows[cnt].Cells[4].Style.Font = new Font(dataGridView2.DefaultCellStyle.Font.FontFamily, 10, FontStyle.Bold);
}
dataGridView2.Rows[cnt].Cells[0].Value = Image.FromFile(dr["image_tpm"].ToString());
dataGridView2.Rows[cnt].Cells[1].Value = Image.FromFile(dr["image_thefind"].ToString());
dataGridView2.Rows[cnt].Cells[2].Value = dr["name"].ToString();
dataGridView2.Rows[cnt].Cells[3].Value = dr["product_url"].ToString();
dataGridView2.Rows[cnt].Cells[4].Value = dr["price"].ToString();
dataGridView2.Rows[cnt].Cells[5].Value = dr["image_accuracy"].ToString();
cnt++;
}
foreach (DataGridViewRow row in dataGridView2.Rows)
{
row.Height = 60;
}
dr.Close();
}
Now, the outofexception does not comes on first time of the click, but it comes after 5-8 clicks on the VIEW column of DGV1.
How can i clear up the memory?
Try to dispose and create datagridview manually. The Code can be like this:
dgv.Dispose();
dgv = new DataGridView();
DataGridViewColumn col1 = new DataGridViewTextBoxColumn();
DataGridViewColumn col2 = new DataGridViewTextBoxColumn();
DataGridViewColumn col3 = new DataGridViewTextBoxColumn();
DataGridViewColumn col4 = new DataGridViewTextBoxColumn();
DataGridViewColumn col5 = new DataGridViewTextBoxColumn();

col2.HeaderText = "COl2";
col3.HeaderText = "COl3";
col4.HeaderText = "COl4";
col5.HeaderText = "COl5";
dgv = new System.Windows.Forms.DataGridView();
dgv.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize;
dgv.Location = new System.Drawing.Point(59, 101);
dgv.Name = "dataGridView1";
dgv.Size = new System.Drawing.Size(240, 150);
dgv.TabIndex = 2;
dgv.Columns.Add(col1);
dgv.Columns.Add(col2);
