Hi Kiran,
Thank you for your interest in Syncfusion Products.
When AutoComplete control is used in a UserControl, the parent form of the UserControl has to be set to the ParentForm property of the AutoComplete control as shown below:
private void UserControl1_Load(object sender, System.EventArgs e)
{
this.autoComplete1.ParentForm = this.ParentForm;
}
If you do not implement the above given code snippet,then AutoComplete will not read the Datasource that is set in UserControl .
Please refer the following sample as per your requirement.
