How do you enable editing in a GridView programatically rather than via its
Tasks menu?

Guy
 
Hello guy,

try to set the AutoGenerateEditButton = true;

Michael,
AutoGenerateEditButton is already true,
and ithe edit button appears, What do I need to do in the RowEditing event
to actually edit the data?

Hello guy,

then use GridView.EditIndex setting the row to edit

You need to handle 3 events. Here is an example for editing a grid with user
info. Note using EditIndex property.

protected void dgUsers_RowEditing(object sender, GridViewEditEventArgs e)

{

System.Web.UI.WebControls.GridView grid = sender as
System.Web.UI.WebControls.GridView;

grid.EditIndex = e.NewEditIndex;

grid.DataSource = System.Web.Security.Membership.GetAllUsers();

grid.DataBind();

}

protected void dgUsers_RowUpdating(object sender, GridViewUpdateEventArgs e)

{

System.Web.UI.WebControls.GridView grid = sender as
System.Web.UI.WebControls.GridView;

System.Web.Security.MembershipUser userToUpdate =
System.Web.Security.Membership.GetUser(dgUsers.DataKeys[e.RowIndex].Value.ToString());

userToUpdate.Email = (dgUsers.Rows[e.RowIndex].Cells[5].Controls[0] as
System.Web.UI.WebControls.TextBox).Text;

System.Web.Security.Membership.UpdateUser(userToUpdate);

bool isAdministrator =
(dgUsers.Rows[e.RowIndex].Cells[4].FindControl("chbAdministrator") as
System.Web.UI.WebControls.CheckBox).Checked;

if (isAdministrator)

System.Web.Security.Roles.AddUserToRole (userToUpdate.UserName, "Admin");

else

System.Web.Security.Roles.RemoveUserFromRole(userToUpdate.UserName,
"rAdmin");

grid.EditIndex = -1;

grid.DataSource = System.Web.Security.Membership.GetAllUsers();

grid.DataBind();

}


protected void dgUsers_RowCancelingEdit(object sender,
GridViewCancelEditEventArgs e)

{

System.Web.UI.WebControls.GridView grid = sender as
System.Web.UI.WebControls.GridView;

grid.EditIndex = -1;

grid.DataSource = System.Web.Security.Membership.GetAllUsers();

grid.DataBind();

}
