Change FormView.Change Mode to Edit after Insert

[J055]

Hi

I'd like to do the following with the FormView/ObjectDataSourc e 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 SelectParameter s 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(objec t sender, EventArgs e)
{
if (!IsPostBack)
{
string sid = Request.QuerySt ring["ID"];
if (sid != null)
{
FormView1.Defau ltMode = FormViewMode.Ed it;
}
else
{
FormView1.Defau ltMode = FormViewMode.In sert;
}
}
}

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

protected void ObjectDataSourc e1_Inserted(obj ect sender,
ObjectDataSourc eStatusEventArg s e)
{
int id = (int)e.ReturnVa lue;
Response.Redire ct(Request.Url. ToString() + "?ID=" + id.ToString(),
true);
}

3. You can always provide the SelectPraramete rs ID in the Selecting event
of ObjectDataSourc e:

protected void ObjectDataSourc e1_Selecting(ob ject sender,
ObjectDataSourc eSelectingEvent Args e)
{
e.InputParamete rs["id"] = Request.QuerySt ring["ID"];
}

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