Data driven tests- How to clear data when using grid?

Question

How would I clear data when using data grid for DDT or data driven tests?

Seems like the only way is to un-select the column

I try the icon with erase which says clear data but that does not work!

also why does it keep having one blank being selected?

This sounds like a bug even if I un-select that blank row it will select the one below that.

I have attached screenshot

If you need to delete data from the entire grid datasource, you an use a groovy script to clear it out the rows. Warning: this will make your grid 100% empty.&nbsp;def grid = testRunner.testCase.testSteps["DataSource"].dataSource.gridModel
int rows = grid.getRowCount();
log.info(rows);
for (int i = 0; i &lt; rows; i++)
{
	log.info(i);
	grid.deleteRows(0);

IgorG: I tend to use a grid DataSource to house data that changes every time I run a specific sort of tests. I work a lot with groovy to try to automate what I can with testing.&nbsp;:smileyhappy:

Check the data file if there are empty lines in the end of the file.

People sure like to use Groovy to solve what already has a UI element for it :) Unless you want to modify it during the test run of course.

The blank line at the end is a UI element so that its easier to create new rows and does not affect your tests. Its just there to make adding a new row quicker.
