I have the following code:
Dim i As Integer = dtResult.Rows.Count
For i = 0 To dtResult.Rows.Count Step 1
strVerse = blHelper.Highlight(dtResult.Rows(i).ToString, s)
' syntax error here
dtResult.Rows(i) = strVerse
Next
I want to add a strVerse to the current row.
What am I doing wrong?

We can update the data in a DataView . The following source code shows how to update data in a DataView . Create a new VB.NET project and drag a DataGridView and a Button on default Form Form1 , and copy and paste the following Source Code on button click event.
To add a new row, declare a new variable as type DataRow. A new DataRow object is returned when you call the NewRow method. The DataTable then creates the DataRow object based on the structure of the table, as defined by the DataColumnCollection.
use SetModified() method to update data table value.
Description. Working with rows is a fundamental part of DataTables, and you want to be able to easily select the rows that you want from the table. This method is the row counterpart to the columns() and cells() methods for working with columns and cells in the table, respectively.
The problem you're running into is that you're trying to replace an entire row object. That is not allowed by the DataTable API. Instead you have to update the values in the columns of a row object. Or add a new row to the collection.
To update the column of a particular row you can access it by name or index. For instance you could write the following code to update the column "Foo" to be the value strVerse
dtResult.Rows(i)("Foo") = strVerse
