I am having problems selecting a row out of the DataGridView on a search. The data source is a DataTable from a database. I am using a search box that checks the DataGridView for a product matching the product key, and i want to select it if found.
Here is what i have:
private void search_btn_Click(object sender, EventArgs e)
{
foreach (DataGridViewRow row in products_dgv.Rows)
{
string tempCode = row.Cells[0].Value.ToString(); //Code comparing
if (tempCode == code_tb.Text) //Checks if code matchs the search code
{
//I would like to do a products_dgv.selectedIndex = row.Index but it
//doesnt work
break;
}
}
}
Any help is much appreciated. Thank You!
You can use the CurrentCell property of the DataGridView to set the selection. If you are using FullRowSelect as selection mode, just use any cells in the row that you would like to select.
For example:
...
if (tempCode == code_tb.Text) //Checks if code matchs the search code
{
products_dgv.CurrentCell = row.Cells[0];
break;
}

I want to click on an exact row in a WinTable where my criteria meets but couldnt succeed so far. I can search criteria for an exact row but I can not get total number of rows so that I would make a loop for all rows. I tried collection and table.Rows.Count,but both brings nothing to me. Can someone help me on this ?
#region Variable Declarations
WinTable uIG1Table = this.UIProMANAGEWindow.UIDefinitionsWindow.UIG1Window.UIG1Table;
WinRow dataGridrow = uIG1Table.GetRow(0);
#endregion
UITestControlCollection rows = uIG1Table.Rows;
// MessageBox.Show(rows[5].RowIndex.ToString());
foreach (WinRow row in uIG1Table.Rows)
{
foreach (WinCell cell in row.Cells)
{
if (cell.Value.ToString() == "E81")
Mouse.Click(cell, new Point(5, 0));
}
}
and this is the code with for loop
int rows = uIG1Table.Rows.Count;
for (int i = 0; i < rows; i++)
{
foreach (WinCell cell in dataGridrow.Cells)
{
if (cell.Value.ToString() == "E81")
Mouse.Click(cell, new Point(5, 0));
}
}
When doing a GetChildren() on a row, you will notice that the first child is of type RowHeader. A user typically clicks the row header to select the row.
Following code will iterate all the rows in a DataGridView and click the row header, effectively selecting the row:
UITestControlCollection rows = YourUIMapTable.Rows;
foreach (UITestControl row in rows)
{
UITestControl rowHeader = row.GetChildren().Single(child => child.ControlType == ControlType.RowHeader);
Mouse.Click(rowHeader);
}
If you want to select a specific row, you can do something like this:
Mouse.Click(YourUIMapTable.Rows[putIndexNumberHere].GetChildren().Single(child => child.ControlType == ControlType.RowHeader));
The sample code above is based on the program I wrote in my answer to this question:
How to get cell color information of a WinCell with codedui?
I have the following code using the Google sheets API and got it working perfectly. It sees all my data and puts it into the app perfectly via the for loop. It runs through the spreadsheets and puts the data in an edit view.
private List<String> getDataFromApi() throws IOException {
String spreadsheetId = "1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms";
String range = "Class Data!A2:E";
List<String> results = new ArrayList<String>();
ValueRange response = this.mService.spreadsheets().values()
.get(spreadsheetId, range)
.execute();
List<List<Object>> values = response.getValues();
if (values != null) {
results.add("Name, Major");
for (List row : values) {
results.add(row.get(0) + ", " + row.get(4));
}
}
return results;
}
As you can see, the for loop retrieves the data one by one until there is no more data inside a specific range in the spreadsheet.
My question: I want to retrieve a specific range, not using a for loop. However, as an example, if I want to get cell A1, and I do result.add(A.get(0)), it doesn't work.
How can I retrieve a specific range within the spreadsheet.
I want to delete row from datagridview when user clicks the delete button.The datagridview bounded to datatable _dt so i remove the row from _dt and try to rebind the modified _dt to datagridview but instead of deleting the row gets added to the last row of the datagridview what am I doing wrong here
private void btnDelete_Click(object sender, EventArgs e)
{
if (dataGridView1 != null && dataGridView1.SelectedRows.Count == 1)
{
string key = dataGridView1.SelectedRows[0].Cells["ID"].Value.ToString();
DataColumn[] keyColumns = new DataColumn[1];
keyColumns[0] = _dt.Columns["ID"];
_dt.PrimaryKey = keyColumns;
rowToDelete = _dt.Rows.Find(key);
_dt.Rows.Remove(rowToDelete);
_dt.AcceptChanges();
SqlCommandBuilder cb = new SqlCommandBuilder(_sqlDa);
_sqlDa.Fill(_dt);
_sqlDa.Update(_dt);
dataGridView1.DataSource = null;
dataGridView1.DataSource = _dt;
}
}
No need for Fill before update and also delete this row
_dt.AcceptChanges();
because this will remove the row from memory and when you call update
only the remaining rows are updated, it will not delete the row from database.
No need to call Fill Before Update, because Fill will get data again from db and your changes will be lost. So This will work for you.
SqlCommandBuilder cb = new SqlCommandBuilder(_sqlDa);
//_sqlDa.Fill(_dt);
_sqlDa.Update(_dt);
I am using openxml to create an excel report. The openxml operates on a template excel file using named ranges.
The client requires a totals row at the end of the list of rows. Sounds like a reasonable request!!
However, the data table I'm returning from the db can contain any number of rows. Using template rows and 'InsertBeforeSelf', my totals row is getting overridden.
My question is, using openxml, how can I insert rows into the spreadsheet, causing the totals row to be be moved down each time a row is inserted?
Regards ...
Assuming you're using the SDK 2.0, I did something similiar by using this function:
private static Row CreateRow(Row refRow, SheetData sheetData)
{
uint rowIndex = refRow.RowIndex.Value;
uint newRowIndex;
var newRow = (Row)refRow.Clone();
/*IEnumerable<Row> rows = sheetData.Descendants<Row>().Where(r => r.RowIndex.Value >= rowIndex);
foreach (Row row in rows)
{
newRowIndex = System.Convert.ToUInt32(row.RowIndex.Value + 1);
foreach (Cell cell in row.Elements<Cell>())
{
string cellReference = cell.CellReference.Value;
cell.CellReference = new StringValue(cellReference.Replace(row.RowIndex.Value.ToString(), newRowIndex.ToString()));
}
row.RowIndex = new UInt32Value(newRowIndex);
}*/
sheetData.InsertBefore(newRow, refRow);
return newRow;
}
I'm not sure how you were doing it with InsertBeforeSelf before, so maybe this isn't much of an improvement, but this has worked for me. I was thinking you could just use your totals row as the reference row. (The commented out part is for if you had rows after your reference row that you wanted to maintain. I made some modifications, but it mostly comes from this thread: http://social.msdn.microsoft.com/Forums/en-US/oxmlsdk/thread/65c9ca1c-25d4-482d-8eb3-91a3512bb0ac)
Since it returns the new row, you can use that object then to edit the cell values with the data from the database. I hope this is at least somewhat helpful to anyone trying to do this...
[Can someone with more points please put this text as a comment for the M_R_H's Answer.]
The solution that M_R_H gave helped me, but introduces a new bug to the problem. If you use the given CreateRow method as-is, if any of the rows being moved/re-referenced have formulas the CalcChain.xml (in the package) will be broken.
I added the following code to the proposed CreateRow solution. It still doesn't fix the problem, because, I think this code is only fixing the currently-being-copied row reference:
if (cell.CellFormula != null) {
string cellFormula = cell.CellFormula.Text;
cell.CellFormula = new CellFormula(cellFormula.Replace(row.RowIndex.Value.ToString(), newRowIndex.ToString()));
}
What is the proper way to fix/update CalcChain.xml?
PS: SheetData can be gotten from your worksheet as:
worksheet.GetFirstChild<SheetData>();
You have to loop all rows and cells under the inserted row,change its rowindex and cellreference. I guess OpenXml not so smart that help you change index automatically.
static void InsertRow(string sheetName, WorkbookPart wbPart, uint rowIndex)
{
Sheet sheet = wbPart.Workbook.Descendants<Sheet>().Where((s) => s.Name == sheetName).FirstOrDefault();
if (sheet != null)
{
Worksheet ws = ((WorksheetPart)(wbPart.GetPartById(sheet.Id))).Worksheet;
SheetData sheetData = ws.WorksheetPart.Worksheet.GetFirstChild<SheetData>();
Row refRow = GetRow(sheetData, rowIndex);
++rowIndex;
Cell cell1 = new Cell() { CellReference = "A" + rowIndex };
CellValue cellValue1 = new CellValue();
cellValue1.Text = "";
cell1.Append(cellValue1);
Row newRow = new Row()
{
RowIndex = rowIndex
};
newRow.Append(cell1);
for (int i = (int)rowIndex; i <= sheetData.Elements<Row>().Count(); i++)
{
var row = sheetData.Elements<Row>().Where(r => r.RowIndex.Value == i).FirstOrDefault();
row.RowIndex++;
foreach (Cell c in row.Elements<Cell>())
{
string refer = c.CellReference.Value;
int num = Convert.ToInt32(Regex.Replace(refer, #"[^\d]*", ""));
num++;
string letters = Regex.Replace(refer, #"[^A-Z]*", "");
c.CellReference.Value = letters + num;
}
}
sheetData.InsertAfter(newRow, refRow);
//ws.Save();
}
}
static Row GetRow(SheetData wsData, UInt32 rowIndex)
{
var row = wsData.Elements<Row>().
Where(r => r.RowIndex.Value == rowIndex).FirstOrDefault();
if (row == null)
{
row = new Row();
row.RowIndex = rowIndex;
wsData.Append(row);
}
return row;
}
Above solution got from:How to insert the row in exisiting template in open xml. There is a clear explanation might help you a lot.
I need to read data from a single worksheet in an Excel 2007 workbook using the Open XML SDK 2.0. I have spent a lot of time searching for basic guidelines to doing this, but I have only found help on creating spreadsheets.
How do I iterate rows in a worksheet and then iterate the cells in each row, using this SDK?
The other answer seemed more like a meta-answer. I have been struggling with this since using LINQ does work with separated document parts. The following code includes a wrapper function to get the value from a Cell, resolving any possible string lookups.
public void ExcelDocTest()
{
Debug.WriteLine("Running through sheet.");
int rowsComplete = 0;
using (SpreadsheetDocument spreadsheetDocument =
SpreadsheetDocument.Open(#"path\to\Spreadsheet.xlsx", false))
{
WorkbookPart workBookPart = spreadsheetDocument.WorkbookPart;
foreach (Sheet s in workBookPart.Workbook.Descendants<Sheet>())
{
WorksheetPart wsPart = workBookPart.GetPartById(s.Id) as WorksheetPart;
Debug.WriteLine("Worksheet {1}:{2} - id({0}) {3}", s.Id, s.SheetId, s.Name,
wsPart == null ? "NOT FOUND!" : "found.");
if (wsPart == null)
{
continue;
}
Row[] rows = wsPart.Worksheet.Descendants<Row>().ToArray();
//assumes the first row contains column names
foreach (Row row in wsPart.Worksheet.Descendants<Row>())
{
rowsComplete++;
bool emptyRow = true;
List<object> rowData = new List<object>();
string value;
foreach (Cell c in row.Elements<Cell>())
{
value = GetCellValue(c);
emptyRow = emptyRow && string.IsNullOrWhiteSpace(value);
rowData.Add(value);
}
Debug.WriteLine("Row {0}: {1}", row,
emptyRow ? "EMPTY!" : string.Join(", ", rowData));
}
}
}
Debug.WriteLine("Done, processed {0} rows.", rowsComplete);
}
public static string GetCellValue(Cell cell)
{
if (cell == null)
return null;
if (cell.DataType == null)
return cell.InnerText;
string value = cell.InnerText;
switch (cell.DataType.Value)
{
case CellValues.SharedString:
// For shared strings, look up the value in the shared strings table.
// Get worksheet from cell
OpenXmlElement parent = cell.Parent;
while (parent.Parent != null && parent.Parent != parent
&& string.Compare(parent.LocalName, "worksheet", true) != 0)
{
parent = parent.Parent;
}
if (string.Compare(parent.LocalName, "worksheet", true) != 0)
{
throw new Exception("Unable to find parent worksheet.");
}
Worksheet ws = parent as Worksheet;
SpreadsheetDocument ssDoc = ws.WorksheetPart.OpenXmlPackage as SpreadsheetDocument;
SharedStringTablePart sstPart = ssDoc.WorkbookPart.GetPartsOfType<SharedStringTablePart>().FirstOrDefault();
// lookup value in shared string table
if (sstPart != null && sstPart.SharedStringTable != null)
{
value = sstPart.SharedStringTable.ElementAt(int.Parse(value)).InnerText;
}
break;
//this case within a case is copied from msdn.
case CellValues.Boolean:
switch (value)
{
case "0":
value = "FALSE";
break;
default:
value = "TRUE";
break;
}
break;
}
return value;
}
Edit: Thanks #Nitin-Jadhav for the correction to GetCellValue().
The way I do this is with Linq. There are lots of sample around on this subject from using the SDK to just going with pure Open XML (no SDK). Take a look at:
Office Open XML Formats: Retrieving
Excel 2007 Cell Values (uses pure
OpenXML, not SDK, but the concepts
are really close)
Using LINQ to Query Tables in Excel
2007 (uses Open XML SDK, assumes
ListObject)
