how to disable data grid editing and deleting

[Bee]

i have a data grid that populates data from sql on page load and its working fine. however  users are able to edit, delete these items although it doesnt affect the database. how do i set the data grid to avoid this

Hello,

Just set the ReadOnly flag to true on the grid itself.

many thank for your time, on that same grid how do i add horizontal and vertical scroll bars

[Emanuel Varga]

Hello again,

You can change the default behavior of the scroll bars, using

grid.VerticalScrollState = ScrollState.AlwaysShow;
grid.HorizontalScrollState = ScrollState.AlwaysShow;

The vertical scroll bar will not be visible if AutoSizeColumnsMode is set to Fill.

If you have any other questions, please let me know.

i have an mdi form and within that mdi form there are multiple forms, so i dont want a situation whereby a user can open as many forms as possible. all i want is the user to open only one form at a time so that the project will not allow you to open any other form without closing an already open form

[Emanuel Varga]

Hello again,

If you have access to the MdiParent form, you can just check the number of MdiChildren.Lenght and based on this create the other form or not.

If you have any other questions, please let me know.

i am struggling to go around it, this is the code i have to open the child forms from the parent
dim child as new frmcustomers
child.mdiparent=me
child.show()
i+=1

so how do i restrict from this

[Emanuel Varga]

if (me.MdiChildren.Lenght > 0)
// do not create any more forms because there is at least 1 child created
   return;

dim child as new frmcustomers
child.mdiparent=me
child.show()

have used
if me.mdichildren.length>0 then
return
dim child as new frmcustomers
child.mdiparent=me
child.show()
i+=1

its saying unused local variable child and when i run the project and try to open the frmcustomers, it doesnt open

[Emanuel Varga]

Do you have any mdichildren in the beginning? wasn't this the ideea? to have only one child active?

i have used this code and its working
dim child as new frmcustomers
frmcustomers.showdialog()
i+=1

[Emanuel Varga]

Private Sub RadMenuButtonItem3_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadMenuButtonItem3.Click
        Dim child As New frmcustomers
        frmcustomers.ShowDialog()
 i += 1
end sub
Private Sub RadMenuButtonItem4_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles RadMenuButtonItem4.Click
        Dim child As New frmRates
        frmRates.ShowDialog()
        i += 1
    End Sub
