Change FormView.ChangeMode to Edit after Insert

[J055]

Hi

I'd like to do the following with the FormView/ObjectDataSource but not sure
of the best approach.

1. Change the FormView mode to Edit if a valid QueryString ID exists or
Insert mode if it doesn't
2. If in Insert mode then when the form is posted it should get the new ID
from the inserted record and change the FormView Mode to Edit
3. The SelectParameters ID must be updated too as it needs to get the new
record.

My InsertMethod business object returns the new ID.

Many thanks
Andrew

Hi Andrew,

1. You can do this by checking the QueryString when the page is first
loaded (non-postback):

protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
string sid = Request.QueryString["ID"];
if (sid != null)
{
FormView1.DefaultMode = FormViewMode.Edit;
}
else
{
FormView1.DefaultMode = FormViewMode.Insert;
}
}
}

2. You can handle this in the Inserted event of ObjectDataSource and do a
redirect to current page with ID appended to the QueryString:

protected void ObjectDataSource1_Inserted(object sender,
ObjectDataSourceStatusEventArgs e)
{
int id = (int)e.ReturnValue;
Response.Redirect(Request.Url.ToString() + "?ID=" + id.ToString(),
true);
}

3. You can always provide the SelectPrarameters ID in the Selecting event
of ObjectDataSource:

protected void ObjectDataSource1_Selecting(object sender,
ObjectDataSourceSelectingEventArgs e)
{
e.InputParameters["id"] = Request.QueryString["ID"];
}

Hope this helps. Please feel free to post here if anything is unclear.
