I want to store a value for every row in a gridview.
I try to set these:
myGridview.Rows[a rowindex].HeaderCell.Value = the value what i want to set;
or
myGridview.Rows[a rowindex].Tag = the value what i want to set;

but after a cell click these properties store null value

How can i set a value for the gridviewrow?

Thank you for your help.

I deleted this solution from my code.
I resolve my proble.
I add a new unvisible column to my datagridview and i set the value in the cells of column.

Thank you again.

Regards.

I just tried setting the Tag property of the row and then displaying it to the Debug window at a later point and it worked fine for me.

How/where are you setting the tag?

How/where are you retrieving the tag?

I have a Form with the DataGridView. In this Form.cs in a method i set the Tag property. I call the this method in the Form_Load. When i run the App in Debug mode, i watch the value of the Tag. After the Form load the value is ok. But when i click on the DataGridView cell the value change null.
I put a break point at the begining of the myDataGridView_CellClick method and there the value is null by that time.

I set and retrieve like these:

in the setter method:

myGridview.Rows[a rowindex].Tag = the value what i want to set;

int the myDataGridView_CellClick method:

var x = myGridview.Rows[a rowindex].Tag;

Do you have any other code that is either clearing the rows or creating a new myGridView?

Are you rebinding after setting the tag? I would think that rebinding would cause you to loose any values associated with the rows.

Hope this helps.
