Good, I have problem when adding a data to a specific column of a datagrid in C #, I get an error that says:
foreach (double inter in intervalo)
{
if(nAle >= (double)intervalo[2*i] && nAle<=(double)intervalo[2*i-1])
{
i += 1;
pos = intervalo.Count;
table.Rows[i].Cells[i] += 1;
break;
}
}
Good Luís,
The error you have, as the message indicates, is that the definition Cells does not exist for System.Data.DataRow .
To get a column of a Row specific within a DataTable you have to do it in the following way:
foreach (double inter in intervalo)
{
if(nAle >= (double)intervalo[2*i] && nAle<=(double)intervalo[2*i-1])
{
i += 1;
pos = intervalo.Count;
table.Rows[i][i] += 1; //Pongo i respetando tu código, el segundo sería el índice de la columna
break;
}
}
The table.Rows[i].Cells[i] works correctly when it comes to DataGridViewRow , but in DataRow is different, I recommend you look at the official Microsoft page and you are well informed of the differences of each class.
System.Data.DataRow does not contain a property named Cells . What you need is to access the index of the row using Rows[index] and then access the column of that row:
foreach (double inter in intervalo)
{
if(nAle >= (double)intervalo[2*i] && nAle<=(double)intervalo[2*i-1])
{
i += 1;
pos = intervalo.Count;
DataRow row = table.Rows[i];
// row[i] retona un System.DataColumn por lo que le asignamos el valor a la columna con el indice i
row[i] += 1
break;
}
}
