Need to use Windows Forms datagridview as a variable in control

Using Windows Forms

I have a tabcontrol , each page has a datagridview. I know the tab page name

tabData.SelectedTab.Name

let's say I have tabPage1 the datagridview on that tab is dgvPage1. Now I want to get the selected row

int row = dgvPage1.CurrentCell.RowIndex;

How can I do this if all I know about is the grid I want is -- String VariableName = "dgvPage1" stored in a variable.

int row = (VariableName).CurrentCell.RowIndex;
String Person = (VariableName).Rows[row].Cells[0].Value.ToString();

I'm not sure I fully understand your question, since you seem to have the expected code in your question:

int row = dgvPage1.CurrentCell.RowIndex;
String Person = dgvPage1.Rows[row].Cells[0].Value.ToString();

Maybe you're asking WHEN you should call this code, but the answer to that is up to you (do you want to call it when a button is clicked or when some kind of event happens, and if so, what is that event) ?

If you're asking how the above works, the "dgvPage1.CurrentCell" part is a special, automatically-updating property that points to the datagrid cell that is currently selected at the time when the code runs. So if you run your program and click on the second column in the second row of your grid, and then you click a button that runs those 2 lines of code, then dgvPage1.CurrentCell will point to that cell you clicked on.

From there, the RowIndex tells you which row the cell is on.

Then, dgvPage1.Rows[row] points to that specific row, and dgvPage1.Rows[row].Cells[0] points to the 1st column in that row.

Then dgvPage1.Rows[row].Cells[0].Value points to the contents that are inside that cell. The contents aren't necessarily a string (a datagrid cell could have other things, like checkboxes), so dgvPage1.Rows[row].Cells[0].Value.ToString() tries to force it to a string.

All that said, I'd strongly recommend you learn WPF and models/databinding. Once you learn how to do that stuff, it makes life SO much easier, and WPF datagrids are a lot more flexible and capable than Winforms datagrids.

Thanks Kevin,

You understood. I do not know which tab or grid I have, but in a variable from a selected item list by the user

gr8Gonzo, thanks but WPF is not an option on this project. I have been given very strict requirements, it must be in Windows Forms.
