RadCombo Items.Add or DataSource give better performance

[Sanjeev]

Hi,
Can any one please suggest which is better from Performance point of view for RADCombo.
Because after 'googling' I found that my first approach is better for small data lets say 100 or 1000 rows.

Example: Here is link what they discuss
http://forums.asp.net/t/1670292.aspx/1

 

 

Dim Item As RadComboBoxItem

 

 

 

For Each row As DataRow In DataTable.Rows
Item = New RadComboBoxItem

 

Item.Text = row("name").ToString()

Item.Value = row("id").ToString()
Combo.Items.Add(Item)

 

 

Next

OR

Combo.DataSource=DataTable
Combo.DataTextField="name"
Combo.DataValueField="id"
Combo.DataBind()


Thanks,
Sanjeev Kumar

Hello Sanjeev,

When dealing with large amount of data it is preferable to used the build-in binding mechanism of the RadComboBox.
