Insert Parameter using .DefaultValue


M

Miro

I created a accessdatasource on my form and it has a parameter for the
insert command.
Then a button to "insert data".
The only way I have found to use that parameter for insert is to use the
..defaultvalue
This seems funny to me.

Instead of doing this:
AccessDataSource1.InsertParameters("AnotherValue").DefaultValue =
TextBox1.Text
AccessDataSource1.Insert()
I was looking to do sometihng like this:
AccessDataSource1.InsertParameters("AnotherValue") = TextBox1.Text
AccessDataSource1.Insert()

or can I only use default value - is that how it is done?

Thanks

Miro

Miro,

The parameter as gotten here:
AccessDataSource1.InsertParameters("AnotherValue") is an object with
properties that may be accessed. You are then setting one of the properties
like this: AccessDataSource1.InsertParameters("AnotherValue").DefaultValue =
TextBox1.Text.

You should be able to see other properties and/or methods of the object
brought up by intellisense. Technically the .DefaultValue property is what
the parameter will be set to if no other input is received. The .Value
property would override the .DefaultValue property. So you could also set
this by: AccessDataSource1.InsertParameters("AnotherValue").Value =
TextBox1.Text with the same result.

That doesnt seem to work, ( I tried that )

here is the error I get for the code I have in my Button1_Click:

If TextBox1.Text <> "" Then
'AccessDataSource1.InsertParameters("AnotherValue").DefaultValue
= TextBox1.Text
'This next line is "underlined blue with an error"
AccessDataSource1.InsertParameters("AnotherValue").value =
TextBox1.Text

AccessDataSource1.Insert()
TextBox1.Text = ""
End If

Error
'value' is not a member of 'System.Web.UI.WebControls.Parameter'.
C:\Users\Miro\Documents\Visual Studio
2008\WebSites\DeployTest\Default5.aspx.vb 12 13 C:\...\DeployTest\

The only options I have that I can put after the ("AnotherValue").XXXXX
is this:
ConvertEmptyStringToNull
DBType
DefaultValue
Direction
GetDatabaseType
Name
Size
ToString
Type
