Software Technology Tips
This tip demonstrates how to optimize code behind DataBound controls in .NET But first we need to set the DataSource property after setting the ValueMember, DisplayMember of DataBound controls such as ComboBox, LookupEdit, ListBox.
Otherwise the control will repopulate as the ValueMember changes.
|
Example in VB.Net:
components used :
cboClientName is the combobox
clientDataTable is a DataTable So we should write in following manner for efficiency :
cboClientName.ValueMember = "Name"
cboClientName.DisplayMember = "Name" cboClientName.DataSource = clientDataTable instead of writing :
cboClientName.DataSource = clientDataTable cboClientName.ValueMember = "Name" cboClientName.DisplayMember = "Name" |
