Hello,
it's my first message on this forum.
I use VS2010, W7, FirebirdSql.Data.FirebirdClient 2.7.7.0 and Firebird 2.5.
Here is my problem.
I have a Form and a select query that executes in the form load event.
The Form has many TabPages and one Tabpages has onr or many
FlowLayoutPanel and every FlowLayoutPanel are the parent of one single
ComboBoX.
The count of FlowLayoutPanel is the count of Rows returning by the
select query.
I want make a databinding betweeen the ComboBoX and every Rows. No
problem when the form loads but when I click on the Tabpage that is
FlowLayoutPanel parent. I raise ArgumentException :« Impossible
databinding between property or column name XXX. Parameter Name DataMember »
But The DataMember is right and the exception is not raised by XXXX.cs
file *but by the Main() method*. Here is the code snippet XXXX.cs file
for
(int i = 0; i< nbRowTjMedecinPatient ; i++)
{
foreach
(Control ctrl in flpMedecin.Controls[i].Controls)
{if
(ctrl is ComboBox)
{ComboBox
cb = (ComboBox)ctrl;
cb.DataBindings.Add("SelectedValue",
tblTjMedecinPatient.Rows[i], "clemed");
}
}
}
Here is the exception code
à System.Windows.Forms.BindToObject.CheckBinding()
à
System.Windows.Forms.BindToObject.SetBindingManagerBase(BindingManagerBase
lManager)
à System.Windows.Forms.Binding.SetListManager(BindingManagerBase
