ASPxComboBox - How to set selected item?

You can either:

• Set the ASPxComboBox.SelectedIndex property;

• Select the required Item by its Value via the ASPxComboBox.Value property:

Code Behind:

cbxJobType.SelectedIndex = 0;
//or
cbxJobType.Value = "0";

Client-Side Script

Give ClientInstanceName property to comboBoxto access it client side and ID property as cbxJobType to access control server side.

 // by text
    comboBox.SetText('Text #2');
    // by value
    comboBox.SetValue('Value #2');
    // by index
    comboBox.SetSelectedIndex(1); 

Server-Side Code

// by text
cbxJobType.Text = "Text #2";
// by value
cbxJobType.Value = "Value #2";
// by index
cbxJobType.SelectedIndex = 1; 

This code works fine too:

cbxJobType.SelectedItem = cbxJobType.Items.FindByValue("Value #2");
