Dynamic field

Question

User-944089421 posted

I have a DetailsView with a few DynamicFields, bound to a LinqDataSource and the DefaultMode is set to Insert on the DetailsView.

What I want to do is initialise one of the textboxes with a value the user will not have to enter on the webpage.

What would seem like a simple thing to do, appears otherwise.  I'm struggling with this now.

Can anyone tell me how I can set this value, either imperatively or declaratively.

Thanks very much.

Gavin

Gavin,

Check this thread out.

The code snippet I believe you are looking for is:

protected void DetailsView1_PreRender(object sender, EventArgs e)
{
	string value = Session["FirstName"].ToString();

	if (!string.IsNullOrEmpty(value))
	{
		var ftuc = DetailsView1.FindFieldTemplate("FirstName") as FieldTemplateUserControl;
		if (ftuc != null)
		{
			var tb = ftuc.DataControl as TextBox;
			tb.Text = value;
			tb.Enabled = false;
		}
	}
}

var ftuc = DetailsView1.FindFieldTemplate("FirstName") as FieldTemplateUserControl;

Note Gavin that the DetailsView1.FindFieldTemplate("FirstName") is the name of the field/column name not the control Id.

Just thought is was worth mentioning [:D]

In your metadata class, use the DefaultValueAttribute(). It is applied when using Insert mode.

[DefaultValue("My Text")]
public object LastName { get; set; }
