Hi,

I am not clear on your question. Do you want to keep primary key of the rows in the gridview? If so you can use a hidden field for this.

I have a table which contains permissionid , userid , itemid and permissionstatus . And the values in that table comes from item table . Now i want that when a user selects any item through checkbox its permission staus become true . So for that i take the permission status as a checkbox and when user selects it i fire an update query on button click . But in that query i have to provide a condition that particular row is selected that's why i want the userid(primary key) from table . Please help

Use this

C#

GridView1.DataKeys[index].Value.ToString()

here index is row index of gridview

check this link

You can have multiple datakeys to access them see this link

Try this one:

C#

GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
HiddenObjectID.Value = Convert.ToString(GvUserDetails.DataKeys[row.RowIndex].Value);
