I Have looked around and I have not found a solid answeer to this question. I am trying to print my datagrid content when I press a button, the main problem is that my datagrid has too much data and only whatever is shown in the screen is printing. I need It to print all data and if the data does not fit in current page create a mew page and print the rest.
Here is my solution printing Data Grid View using System.Drawing.Printing
using System.Drawing.Printing;
private int PageCounter { get; set; } = 1;
private int RowCounter { get; set; }
Print Button
private void BtnPrint_Click(object sender, EventArgs e)
{
PrintDocument printDoc = new PrintDocument();
IQueryable<PaperSize> paperSizes = printDoc.PrinterSettings.PaperSizes.Cast<PaperSize>().AsQueryable();
printDoc.DefaultPageSettings.PaperSize = paperSizes.First(ps => ps.Kind == PaperKind.A4);
printDoc.DefaultPageSettings.Margins = new Margins(0, 0, 0, 0);
pageCounter = 1;
printDoc.PrintPage += PrintDoc_PrintPage;
printDoc.Print();
}

I have a Xamarin C# IOS app I wrote, using a uitableviewsource to display an unordered list. Everything looks fine until I scroll up, then the text goes up into the header and when I scroll back down it disappears.
The code for the header is as follows
public override UIView GetViewForHeader(UITableView tableView, nint section)
{
UIView view = new UIView(new Rectangle(0, 65, 320, 90));
UILabel label = new UILabel

I am populating the table view using a UITableViewCell as follows;
public void SetData(string str0, string str1, string str2, string str3, int id, string str4)
{
lbC0.Text = str0;
lbC1.Text = str1;
lbC2.Text = str2;
lbC3.Text = str3;
lbcst.Text = str4;
lbId.Text = id.ToString();
}
public override void LayoutSubviews()
{
nfloat lbWidth = Bounds.Width / 4;
nfloat lbWidth2 = lbWidth - 35;
nfloat lbWidth3 = lbWidth2 + 70;
nfloat lbWidth4 = lbWidth3 + 70;
nfloat lbWidth5 = lbWidth4 + 65;
nfloat lbWidth6 = lbWidth5 + 75;
nfloat lbHeight = this.Bounds.Height;
if (lbC0 != null)
{
lbC0.Frame = new CGRect(2, 55, lbWidth, lbHeight);
lbC1.Frame = new CGRect(lbWidth2, 55, lbWidth, lbHeight);
lbC2.Frame = new CGRect(lbWidth3, 55, lbWidth, lbHeight);
lbC3.Frame = new CGRect(lbWidth4, 55, lbWidth, lbHeight);
lbcst.Frame = new CGRect(lbWidth5, 55, lbWidth, lbHeight);
}
}
Any help would be greatly appreciated.
Thanks
I spent weeks searching for an answer. What I finally found was I needed my subviews bounds within my TableViewCell’s bounds. This was all well and good, but I couldn’t figure out how to make it so. I tried everything I found, all to no avail. What finally ended up solving it for me was this. In my LayoutSubviews method, when setting the height of the subview, I subtracted 100 from Bounds.Height and that fixed it, it now scrolls up and down. How simple a fix... how hard to find
Here is the code I changed;
public override void LayoutSubviews()
{
nfloat lbWidth = Bounds.Width / 4;
nfloat lbWidth2 = lbWidth - 35;
nfloat lbWidth3 = lbWidth2 + 70;
nfloat lbWidth4 = lbWidth3 + 70;
nfloat lbWidth5 = lbWidth4 + 65;
nfloat lbWidth6 = lbWidth5 + 75;
-->nfloat lbHeight = this.Bounds.Height - 100;<--
if (lbC0 != null)
{
lbC0.Frame = new CGRect(2, 55, lbWidth, lbHeight);
lbC1.Frame = new CGRect(lbWidth2, 55, lbWidth, lbHeight);
lbC2.Frame = new CGRect(lbWidth3, 55, lbWidth, lbHeight);
lbC3.Frame = new CGRect(lbWidth4, 55, lbWidth, lbHeight);
lbcst.Frame = new CGRect(lbWidth5, 55, lbWidth, lbHeight);
}
}
I have a function in devexpress report which creates table from SQL query dynamically:

private XRTable CreateXRTableDetail(DataTable dtAra)
{
XRTable table = new XRTable();
table.BeginInit();
table.LocationFloat = new DevExpress.Utils.PointFloat(0, 5F);
table.Borders = BorderSide.All;
int tableHeight = 0;
int tableWidth = 0;
for (int i = -1; i < 4; i++)
{
XRTableRow row = new XRTableRow();
for (int j = 0; j < 6; j++)
{
XRTableCell cell = new XRTableCell();
cell.Padding = 1;
Unit width = new Unit(cellWidth[j], UnitType.Pixel);
cell.Width = (int)width.Value;
cell.Weight = 1;
cell.TextAlignment = TextAlignment.MiddleCenter;
tableWidth += cell.Width;
if (i == -1)//Header
{
row.Height = 15;
cell.Text = dtAra.Columns[j].ColumnName;
cell.BackColor = Color.Gainsboro;
cell.Font = new Font("tahoma", 6);
}
else
{
row.Height = 40;
cell.Text = dtAra.Rows[i][j].ToString();
cell.Font = new Font("tahoma", 5);
}
row.Cells.Add(cell);
}
tableHeight += row.Height;
table.Rows.Add(row);
}
tableWidth = tableWidth / table.Rows.Count;
table.Size = new Size(tableWidth, tableHeight);
table.EndInit();
return table;
}
I assing cell widths from cellWidth array but all columns are initialising with same width.
How can I set cell width as I want?
Try this:
int width = 40;
cell.SizeF = new SizeF(cell.SizeF.Width + width, cell.SizeF.Height);
My problem is that is that my code prints the images overlapping each other. I do not know how to change the x and y positions. The printer should print 3 images per row and then move to the next row.

Desired output :
I am getting :

I have observed the code and found the issue.. in panel1_print u are not incrementing the values properly..
I have made the required changes now u will get the 4 bar in a line and 5th one in another line - check the attached image.
just replace ur panel1_Paint with this new code thats it you can find the changes..
I have marked them as
//start changes by Deepak
..
..
..
//end changes by Deepak
and also declare two variables loopValX and loopValY as int
here is the code..

You Should do it with the help of a DataGridView (That Contains Images in a Column).
The Images Will Then Print in each new row or column (by modifying as your desire)
The Following Class will do your work by passing it the whole DataGridView And Header in its constructor.

Your position variables are being declared inside the loop, meaning that they are reset for each pass through the loop. Keep position variables for X and Y outside of the loop over serial and adjust it for the total width (and height, if you start a new row of barcodes) of each barcode.
I have a 10*10 plane of cubes. I want only visible cubes to be drawn, so I use a Bounding frustum. The problem is that when the first cube from the grid (at location 0,0) gets out of the frustum, all cubes disappear.
Here is my code in Cube.cs:
public class Cube

Vector3 scale;
float textureScale;
GraphicsDevice device;
Effect effect;
VertexBuffer vertexBuffer;
Texture2D texture;
public Vector3 GlobalPosition = new Vector3(0, 0, 0);

this.textureScale = textureScale;

Draw() method in Main.cs:
for (int i = 0; i < 10; i++)
{
for (int k = 0; k < 10; k++)
{
Cube cube = new Cube(Vector3.One, 1, effect, woodTexture, device);
if (cube.IsVisible(View * Projection))
{
cube.Draw(View, Projection, new Vector3(2 * i, 0, 2 * k));
}
}

I would also like if you can give me link to an atlas texturing tutorial/sample, Thanks!
Your cube.IsVisible(...) method does not take into account latter transformation you're applying when you're drawing the cube, i.e you're always checking against your original cube, not the transformed ones.
Please reference this answer as it touches both your culling problem (frustum-box) as well as instancing.
