Are you interrogated the DataGridView or used in the automation windows form?

Post screenshot for understanding.

To bind the data to gridview, assign value to datasource property in the automation.

Iterate rows to read the data.

What is your requirement? Are you binding data from table to datasource and then reading from grid? if yes then you have the data in table so no need to read from grid.

Provide your requirement for further understanding.

Use excel export method to display data in datagridview and attached screenshot to read values from selected row in the datagridview.

Ok, but how can we export data dynamically from excel to datagridview?

What do you mean dynamically? You want to export few columns and rows data?

Use export method in the automation flow whenever you want to export data.

Dynamically means in the export data i will mention the cell start and end. instead it should get all the data from excel. how can we achieve cell start and end dynamically.
