ScriptManager.RegisterClientScriptBlock works properly only while debugging - html

Question

Using RegisterClientScriptBlock I have no problem whith displaying the warning alert but after I close the pop up the binding becomes a real mess. The weird thing is that when I try to debug it and go with F10 the binding is ok.
This this a code behind method:
protected void lvContratFonds_OnItemDeleting(object source, ListViewDeleteEventArgs e)
{
try
{
ListView lv = (ListView)source;
int contratId = int.Parse(((HiddenField)lv.Parent.FindControl("hdnContratId")).Value);
int anneeFiscaleId = int.Parse(((HiddenField)lv.Items[e.ItemIndex].FindControl("hdnAnneeFiscaleId")).Value);
int contratFondId = int.Parse(((HiddenField)lv.Items[e.ItemIndex].FindControl("hdnContratFondId")).Value);
ImageButton lnkSupprimerContratFonds = (ImageButton)lv.Items[e.ItemIndex].FindControl("lnkSupprimerContratFonds");
string errMsg = String.Empty;
errMsg = ContratFondBLL.DeleteSingleContratFond(contratFondId, ((PageProjet)Page).ProjetId);
if (errMsg.Length == 0)
{
ContratsFondsTransBLL.DeleteAllContratFondTransByContratId(contratFondId, ((PageProjet)Page).ProjetId);
}
else
{
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "ClientScript", "alert('" + Resources.GPWebResource.errContratFondDelete.ToString() + "')", true);
}
bindContrats();
}
catch(Exception ex)
{
throw (ex);
}
}

Answer 1

can you please explain what you mean by "the binding becomes a real mess"? Do you get duplicates?
Also, are you able to post the code for your bindContrats() method?
Edit 1:
ScriptManager.RegisterClientScriptBlock(lvContratFonds, typeof(ListView), "ClientScript", "alert('" + Resources.GPWebResource.errContratFondDelete.ToString() + "')", true);
Edit 2:
if (errMsg.Length == 0)
{
ContratsFondsTransBLL.DeleteAllContratFondTransByContratId(contratFondId, ((PageProjet)Page).ProjetId);
bindContrats(); // re-bind data
}
else
{
e.Cancel = true;
ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "ClientScript", "alert('" + Resources.GPWebResource.errContratFondDelete.ToString() + "')", true);
/* don't re-bind! */
}
