Answer 1

I suspect there is no matching column of datatable with datagridview column....Check the column of datagridview with datatable column....

For test, make dataGridView1.AutoGenerateColumns to true and check whether the datagridview fill the data or not...

dataGridView1.AutoGenerateColumns= true;

You can create the datagridview column by following way:

Go to properties of datagridview and then go to Columns Section where you can add new column in datagridview according to your datatable....Match DataPropertyName with your datatable column and keep AutoGenerateColumns to false and then it'll works fine...
