Searching for Text in a Windows ListView

If this is a standard ListView control type, the various properties and methods available can be found at https://support.smartbear.com/testcomplete/docs/reference/test-objects/controls/desktop/win32/list-view/index.html

Although, this looks less like a ListView and more like a grid of some sort...

https://support.smartbear.com/testcomplete/docs/app-objects/specific-tasks/grids/basic-concepts.html gives you some starting points.

Depending upon what the control is and what properties/methods/etc are available on the control, the methodology may vary.  What I've done for searching many grid types is simply a for loop from 0 to grid.RowCount, checking the value of column 0 on each row... if I find the desired lab value, I store the rowindex for that lab in a variable and break out of the for loop.

But... for the specifics of YOUR control, can you give us a screenshot of what the grid shows up as in the Object Browser or Object Spy, being sure to include as many properties and methods available under "Advanced"...
