Example

The sample code below shows you how to utilize the collect input function for direct value retrieval in server side using FlyPostBackAction property.

C#	Copy Code
private void WebGrid1_InitializeDataSource(object sender, ISNet.WebUI.WebGrid.DataSourceEventArgs e) { if (WebGrid1.FlyPostBackAction == PostBackAction.RefreshData) { // only fill data when flypostbackaction is refreshdata // note that we can now directly retrieving TextBox1.Text and DropDownList1.SelectedValue oleDbDataAdapter1.SelectCommand.CommandText = "select * from customers where contactname like '" + TextBox1.Text + "%'" +(DropDownList1.SelectedValue != "(all)" ? " and country = '" + DropDownList1.SelectedValue + "'" : ""); oleDbDataAdapter1.Fill(dsNorthWindEnt1.Customers); } e.DataSource = dsNorthWindEnt1; }

Copy Code

private void WebGrid1_InitializeDataSource(object sender, ISNet.WebUI.WebGrid.DataSourceEventArgs e)
{
   if (WebGrid1.FlyPostBackAction == PostBackAction.RefreshData) 
   {
   // only fill data when flypostbackaction is refreshdata

   // note that we can now directly retrieving TextBox1.Text and DropDownList1.SelectedValue
   oleDbDataAdapter1.SelectCommand.CommandText = "select * from customers where contactname like '"   + TextBox1.Text + "%'" +(DropDownList1.SelectedValue != "(all)" ? " and country = '" +  DropDownList1.SelectedValue + "'" : "");


   oleDbDataAdapter1.Fill(dsNorthWindEnt1.Customers);
   }
   e.DataSource = dsNorthWindEnt1;
}

Remarks

OnTheFly-PostBack is a way where data can be requested on-the-fly and rendered to client in transparent way without the need to perform full page refresh. The OnTheFly-PostBack architecture initially implemented individually in Intersoft's flagship products --WebCombo.NET and WebGrid.NET, and have been existed under the sub architecture of Intersoft WebCommonControl architecture.

The feature allows data interactions such as sorting, grouping, retrieving more records, loading child table's rows on demand, to be performed without page refresh. That means a much enhanced user's experience on user view point and faster server's response as well as reduced bandwidth and resources usage on developer view point.

Now with all the advantages of the OnTheFly architecture, it will be good if it can be further extended for more complex scenarios, such as collect all inputs automatically to be processed in server-side during OnTheFly postback. In previous version you need to create hidden input field and fill it manually which is time consuming.
