Change The InsertCommand Of A Datasource Before Insert

Hi,

I am trying to set the InsertCommand of a SqlDataSource prior to a new record being created in DetailsView. It has to be changed because certain fields are not being used in one scenerio and it is causing Null's to be written to the database.

Here is what I have tried:

I set the Insert command on page Load:

protected void Page_Load(object sender, EventArgs e)

{

SqlDataSource3.InsertCommand = "Insert into table (name,realName,type,extraValue) VALUES (@name,@realName,@type,@extraValue)";

}

But I don't want to insert the "extraValue if a certain condition is true so I want to change the insert command to SqlDataSource3.InsertCommand = "Insert into table (name,realName,type) VALUES (@name,@realName,@type)

I tried to do that in the following:

protected void DetailsView1_ItemInserted(Object sender, System.Web.UI.WebControls.DetailsViewInsertedEventArgs e)

{

SqlDataSource3.InsertCommand = "Insert into table (name,realName,type,extraValue) VALUES (@name,@realName,@type,@extraValue)";

if (e.Exception != null)

{

ErrorMessageLabel.Text = "An error occured while entering this record. Please verify you have entered data in the correct format.";

e.ExceptionHandled = true;

Response.Write(e.Exception);

}

GridView1.DataBind();

GridView1.DataBind();

}

But it doesn't seem to change,

Any Help would be appreciated,

Doug
