Question

Please help me with a code snippet to insert a value to a particular row which already exists in my DataTable .

DataRow myrow;
for (i = 1; i <= cnt2+1; i++)
{
    myrow = finalRprt.NewRow();
    for (j = 1; j <= lstSubName.Count + 4; j++) 
    {
       myrow[j] = "-";
    }
    finalRprt.Rows.Add(myrow);
}

Now I want to add a value to the particular row depending on a condition. How can I do

Answer 1

This question is quite vague. But you can for example use the DataRow.SetField extension methid to set a field of a DataRow.

You can either use the indexer to get a row of a DataTable or use Linq-To-DataTable to find the rows you’re searching for.

DataRow row = table.AsEnumerable()
                   .Where(r => r.Field<int>("ID")==ID)
                   .Single();
row.SetField("Name", newName);

Generic Field and SetField Methods (LINQ to DataSet)

Now you need a DataAdapter to update your database (if you want).
