Index was outside the bounds of the array.

Guha Prabakaran

All,

When it hits the Bold line, I get the error, Index was outside the bounds of the array.
Anyone know what I need to know.
Thanks

public static DataGridViewSelectedCellCollection CopyDataGridViewCells(DataGridView dgv, bool alsoCopyToClipBoard)

{

DataGridViewSelectedCellCollection selectedCells = dgv.SelectedCells;

if (alsoCopyToClipBoard)

{

DataGridViewCell[,] cells = SortCells(selectedCells);

CopyToClipboard(cells);

}

return selectedCells;

}

You want to copy a bunch of cells? How do you get the cells that you want to copy? Do you get them in an array? (DataGridViewCell[]) or as a row? (DataGridViewRow)

What object holds the data that you want to copy and what type is the object?

Mikael,
Yes, What I am doing is copying the cells I have selected to be pasted later. So the class that I got for another gentleman, which I am using is defining an instance of DataGridViewCell and populating this with the data from the selected cells.
Would you know of an alternate way for me to be able to copy and paste into a DataGridView?
I do not see a way to attach the class, if not I can attach it.
Thanks

Ah ic, well in that case, i'm guessing you only want to go through the cells you've fetched from a DataView or something else? What exactly is it that you want to do?

If it's only to go through the cells you've selected or fetched just use:
DataGridViewSelectedCellCollection cellCollection = dataGridView.SelectedCells;
...

Then use the functions that cellCollection offer to traverse the cells, it should be compatible with foreach (DataGridViewCell cell in cellCollection) ...

If you want to create a local copy then the collection has a function called CopyTo that you can use like this:

DataGridViewCell[] cells = new DataGridViewCell[cellCollection.Count];
cellCollection.SelectedCells.CopyTo(cells, 0);

Mikael,

I still get
Error 3 Cannot create an instance of the abstract class or interface

when I do

DataGridViewCell[,] cells = new DataGridViewCell[colCount - 1, rowCount - 1];

int i;

for (i = 0; i < colCount; i++)

{

int j;

for (j = 0; j < rowCount; j++)

{

cells[i, j] = new DataGridViewCell();

}

}

Thanks again.

Ops, i guess that one's my fault, my first post was a bit wrong ^^; It's fixed now though :)

Just a small fix needed :)

DataGridViewCell[i, j] = new DataGridViewCell();
to
cells[i, j] = new DataGridViewCell();

Mikael,
I tried this and I get compile errors

Error 3 'System.Windows.Forms.DataGridViewCell' is a 'type' but is used like a 'variable'

Error 4 Cannot create an instance of the abstract class or interface

DataGridViewCell[,] cells = new DataGridViewCell[colCount - 1, rowCount - 1];

int i;

for (i = 0; i < colCount; i++)

{

int j;

for (j = 0; j < rowCount; j++)

{

DataGridViewCell[i, j] = new DataGridViewCell();

}

}

// This only created the frame that's going to hold the DataGridViewCell objects
DataGridViewCell[,] cells = new DataGridViewCell[15, 1];

// You're entering the frame and grabbing at something that's not there
foreach (DataGridViewCell cell in selectedCells)
{
cells[0, 1].Value = cell.value;

}

// You have to create the cells before assigning them values
cells[0, 0] = new DataGridViewCell();
cells[0, 1] = new DataGridViewCell();
....
