Where is data updated in a DataGridView?

I am creating a tab page entirley programatically from a button press in the root page of a tabbed control. At present all the page initialisation takes place in the button click method. After all the instantiation, data capture from file and so on, I finally want to adjust the column widths in the data grid view, so that all the row data appears without having to have horizontal scroll bars. With the help of all your contributors I have managed to get it all working but the last step. Running at full speed it appears the DataGridView is accessed before the data load from the table is complete as it fails with an exception because the count derived from RegistersGrid.ColumnCount (local variable l) is zero. It all works fine if I step through the code. I am assuming that I need to put a Mutex of some form to wait for the transfer to complete, but I can't work out where that is taking place in order to reset the flag! If someone can point me in the right direction or if there is better more structured way to approach this I would deeply appreciate the help :-)
I have included all the code in the method just in case, I am afraid I date back a long way so if this looks like the awkward child of assembler,pascal and c with a little c# thrown in, my apologies....it's my age :-)

Crossout whole row

I try crossout row in table. Line must be over all cells in center vertical.
So I add new shape to cell, like this:
var cell = node as Cell;
var width = cell.CellFormat.Width;
var line = new Shape(args.Document, ShapeType.Line);
line.Width = width;
line.HorizontalAlignment = HorizontalAlignment.Center;
line.RelativeVerticalPosition = RelativeVerticalPosition.Paragraph;
line.Top = 5;
line.BehindText = true;
line.WrapType = WrapType.None;
line.StrokeColor = Color.Black;
line.Stroke.LineStyle = ShapeLineStyle.Single;
line.StrokeWeight = 1;
_builder.MoveTo(cell.LastParagraph);
_builder.InsertNode(line);
But this work only when I have single text line in cell, if is two or more line text, my crossout line is not center:
How fix it?
Maybe is other solution for crossout whole row?

You can build logic on the following code that inserts a full-width Line Shape at the middle of each Cell in Table.
Document doc = new Document("E:\\temp\\in.docx");
DocumentBuilder builder = new DocumentBuilder(doc);
LayoutCollector collector = new LayoutCollector(doc);
LayoutEnumerator enumerator = new LayoutEnumerator(doc);
foreach (Table table in doc.FirstSection.Body.Tables)
{
foreach (Row row in table.Rows)
{
foreach (Cell cell in row.Cells)
{
enumerator.Current = collector.GetEntity(cell.FirstParagraph);
while (enumerator.Type != LayoutEntityType.Cell)
{
enumerator.MoveParent();
}
double top = enumerator.Rectangle.Top + (enumerator.Rectangle.Height / 2);
double left = enumerator.Rectangle.Left;
double width = enumerator.Rectangle.Width;
builder.MoveTo(table.NextSibling);
Shape line = builder.InsertShape(ShapeType.Line, width, 0);
line.Top = top;
line.Left = left;
line.RelativeHorizontalPosition = RelativeHorizontalPosition.Page;
line.RelativeVerticalPosition = RelativeVerticalPosition.Page;
line.BehindText = true;
line.WrapType = WrapType.None;
line.StrokeColor = Color.Blue;
line.Stroke.LineStyle = ShapeLineStyle.Single;
line.StrokeWeight = 1;
}
}
}
doc.Save("E:\\temp\\19.1.docx");
Hope, this help. I work with Aspose as Developer Evangelist.

xamarin creating a tablelayout with 2 buttons on each row

i've been trying to create a Table Layout with 2 buttons next to eachother. i've been reading around, however i can't seem te get it to show anything on the screen. this is my current code for the TableLayout.
TableLayout ll = FindViewById<TableLayout>(Resource.Id.buttonLayout);
TableLayout llInner = new TableLayout(this);
TableLayout.LayoutParams lp = new TableLayout.LayoutParams(LinearLayout.LayoutParams.FillParent, LinearLayout.LayoutParams.WrapContent);
llInner.Orientation = Orientation.Horizontal;
llInner.LayoutParameters = lp;
llInner.WeightSum = 2;
ll.AddView(llInner);
var i = 0;
var row = new TableRow(this);
//TableRow.LayoutParams rowlayout = new TableRow.LayoutParams(TableRow.LayoutParams.MatchParent, TableRow.LayoutParams.WrapContent);
row.LayoutParameters = lp;
foreach (var series1 in series)
{
var b = new Button(this);
b.Text = series1.Series;
//lp = new TableLayout.LayoutParams(1, LinearLayout.LayoutParams.WrapContent);
b.LayoutParameters = lp;
row.AddView(b);
i =+ 1;
if (i > 1)
{
llInner.AddView(row, new TableLayout.LayoutParams(TableLayout.LayoutParams.MatchParent, TableLayout.LayoutParams.WrapContent));
row = new TableRow(this);
row.LayoutParameters = lp;
i = 0;
}
}
any suggestions?
thanks in advance,
Bjorn

i've been trying to create a Table Layout with 2 buttons next to eachother.
Just from your code, besides the original TableLayout named buttonLayout, you created another TableLayout and a TableRow, and then added Button controls into this row, but you never add this row to the view of your TableLayout, and you need to pay attention to the LayoutParams, you used a TableLayout.LayoutParams for all controls, but inside it is the LinearLayout.LayoutParams, that's not right.
Since I don't have your series, I can't really understand what you're doing in foreach, here I just post a sample code:
TableLayout ll = FindViewById<TableLayout>(Resource.Id.buttonLayout);
ll.WeightSum = 2;
ll.Orientation = Orientation.Horizontal;
TableRow row = new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.MatchParent, TableRow.LayoutParams.WrapContent);
row.LayoutParameters = lp;
var b = new Button(this);
b.Text = "Button1";
b.LayoutParameters = new TableRow.LayoutParams(TableRow.LayoutParams.MatchParent, TableRow.LayoutParams.WrapContent);
row.AddView(b);
var bb = new Button(this);
bb.Text = "Button2";
bb.LayoutParameters = new TableRow.LayoutParams(TableRow.LayoutParams.MatchParent, TableRow.LayoutParams.WrapContent);
row.AddView(bb);
ll.AddView(row);
ll.Invalidate();

i was doing allot of stuff that wasn't needed. but my dumbest mistake was the part where i did i =+ 1; instead of i += 1;
this is how my code looks now. its doing wat it needs to do now.
TableLayout ll = FindViewById<TableLayout>(Resource.Id.buttonLayout);
//TableLayout llInner = new TableLayout(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(LinearLayout.LayoutParams.MatchParent, LinearLayout.LayoutParams.MatchParent);
//ll.Orientation = Orientation.Horizontal;
//ll.LayoutParameters = lp;
//ll.WeightSum = 2;
//ll.AddView(llInner);
var i = 0;
var row = new TableRow(this);
row.WeightSum = 2;
//TableRow.LayoutParams rowlayout = new TableRow.LayoutParams(TableRow.LayoutParams.MatchParent, TableRow.LayoutParams.WrapContent);
//row.LayoutParameters = lp;
foreach (var series1 in series)
{
var b = new Button(this);
b.Text = series1.Series;
lp.Weight = 1;
//lp = new TableLayout.LayoutParams(1, LinearLayout.LayoutParams.WrapContent);
b.LayoutParameters = lp;
row.AddView(b);
i += 1;
if (i > 1)
{
ll.AddView(row, new TableLayout.LayoutParams(TableLayout.LayoutParams.MatchParent, TableLayout.LayoutParams.WrapContent));
row = new TableRow(this);
row.LayoutParameters = lp;
i = 0;
}
allot of stuff is commented because i've been messing around with it for a while now.

Why when adding links to datagridview it's adding only one row?

In this case there are 40 links. but when running the program i see it's adding only one row the last one.
public Form1()
{
InitializeComponent();
label2.Visible = false;
label3.Visible = false;
label4.Visible = false;
label7.Visible = false;
tbxMainDownloadPath.Text = Properties.Settings.Default.LastSelectedFolder;
if (tbxMainDownloadPath.Text != "")
downloadDirectory = tbxMainDownloadPath.Text;
tracker = new DownloadProgressTracker.DownloadProgress(50, TimeSpan.FromMilliseconds(500));
string[] countries = File.ReadAllLines(#"CountriesNames.txt");
string[] countriesCodes = File.ReadAllLines(#"CountriesCodes.txt");
foreach (string country in countries)
{
countryList.Add(country);
string countryPath = Path.Combine(downloadDirectory, country);
if (!Directory.Exists(countryPath))
Directory.CreateDirectory(countryPath);
}
foreach (string code in countriesCodes)
{
codesList.Add(code);
}
codeToFullNameMap = codesList
.Select((code, index) => index)
.ToDictionary(
keySelector: index => codesList[index],
elementSelector: index => countryList[index]);
lines = File.ReadAllLines(#"links.txt");
for (int i = 0; i < lines.Length; i++)
{
RichTextBoxExtensions.AppendText(true, richTextBox1, "Ready: ", Color.Red, 8.25f);
richTextBox1.AppendText(lines[i] + (i < lines.Length - 1 ? Environment.NewLine : String.Empty));
}
for (int i = 0; i < countriesCodes.Length; i++)
{
dataGridView1.Columns.Clear();
dataGridView1.ColumnCount = 2;
dataGridView1.Columns[0].Name = "Country";
dataGridView1.Columns[1].Name = "Code";
var countryName = codeToFullNameMap[countriesCodes[i]];
string[] row = new string[] { countryName, countriesCodes[i] };
dataGridView1.Rows.Add(row);
DataGridViewLinkColumn dgvLink = new DataGridViewLinkColumn();
dgvLink.UseColumnTextForLinkValue = true;
dgvLink.LinkBehavior = LinkBehavior.SystemDefault;
dgvLink.HeaderText = "Link Data";
dgvLink.Name = "SiteName";
dgvLink.LinkColor = Color.Blue;
dgvLink.TrackVisitedState = true;
dgvLink.Text = lines[i];
dgvLink.UseColumnTextForLinkValue = true;
dataGridView1.Columns.Add(dgvLink);
}
}
In countriesCodes there are 40 items.
The first problem is that it's adding only one country and it's link and it's the last one, it's not adding the rest.
Second problem is how can i make it to be moved to the right the ? I mean when running i'm using the mouse to drag the link column to the right to the datagridview end side on the right. How can i make to be already to the right end side ? Screenshot added after i dragged it to the right:
And third last problem how to remove the highlight from Country ? I don't want it to highlight anything. Now the highlight is automatic on the country when running the program.
Upodate
Solved all the problems i had:
for (int i = 0; i < countriesCodes.Length; i++)
{
dataGridView1.ColumnCount = 2;
dataGridView1.Columns[0].Name = "Country";
dataGridView1.Columns[1].Name = "Code";
var countryName = codeToFullNameMap[countriesCodes[i]];
string[] row = new string[] { countryName, countriesCodes[i] };
dataGridView1.Rows.Add(row);
DataGridViewLinkColumn dgvLink = new DataGridViewLinkColumn();
dgvLink.UseColumnTextForLinkValue = true;
dgvLink.LinkBehavior = LinkBehavior.SystemDefault;
dgvLink.HeaderText = "Link Data";
dgvLink.Name = "SiteName";
dgvLink.LinkColor = Color.Blue;
dgvLink.TrackVisitedState = true;
dgvLink.Text = lines[i];
dgvLink.UseColumnTextForLinkValue = true;
dataGridView1.Columns.Add(dgvLink);
}
this.dataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;
dataGridView1.EnableHeadersVisualStyles = false;
dataGridView1.DefaultCellStyle.SelectionBackColor = dataGridView1.DefaultCellStyle.BackColor;
dataGridView1.DefaultCellStyle.SelectionForeColor = dataGridView1.DefaultCellStyle.ForeColor;
dataGridView1.AllowUserToAddRows = false;
dataGridView1.BackgroundColor = System.Drawing.SystemColors.Control;

for (int i = 0; i < countriesCodes.Length; i++)
{
dataGridView1.Columns.Clear();
You are clearing your columns 40 times, so only the last iteration through the loop leaves anything to display. Do all of your dataGridView1.Columns setup before the for loop. The for loop should only be adding Rows.

Open XML MS Word Table Heading Row Height Text Direction Bottom to Top Left to Right

I am using Open XML SDK 2.5 to insert Tables in a Word Document. The issue I currently have is with the row height of my table heading. It works fine with normal text direction of Left to Right Top to Bottom LTTB. However as soon as I set the Text Direction to Bottom to Top Left to Right BTLR my heading rows do not adjust to fit the cell contents.
