Solution 1

DataTable Dtb1 = new DataTable();
BindingSource Bnd1= new BindingSource();
Bnd1.DataSource = Dtb1;
int RowNo = Bnd1.Find("MyFieldName", 'a');
if (RowNo != -1)
{
//RowNo is that Row
MyResult=Dtb1.Rows[RowNo]["MyFieldName"].ToString();
}

Solution 2

Try:

C#

int index = -1;
DataRow[] rows = dt.Select("MyColumnName Like '%a%'");
if (rows.Count() > 0)
    {
    index = myDataTable.Rows.IndexOf(rows[0]);
    }

Solution 4

if you have primary key column in the data table you can use
DataRow dr = DataTable1.Rows.Find([primary key value]);

which will give you the datarow object.and after can use method IndexOf available Rows

Datatable1.Rows.IndexOf(dr);

Solution 5

My Solution in vb.net

VB

Dim drow As DataRow = datatable1.Select("YourColumn='" & YourValueString & "'")(0)
Dim tempIndex as integer =datatable1.Rows.IndexOf(drow)

in C#:

C#

DataRow drow = datatable1.Select(("YourColumn=\'" 
                + (YourValueString + "\'")))[0];
int tempIndex = datatable1.Rows.IndexOf(drow);
