Property Value

| Int32 | An integer value that represent the end index. |

Example
The following section of the Filtering Large Data Source online demo illustrates how the ASPxComboBox.ItemsRequestedByFilterCondition and ASPxComboBox.ItemRequestedByValue events of the ASPxComboBox editor can be handled to filter the editor’s data source containing a large number of records.
Note
To work properly, both the ItemsRequestedByFilterCondition and ItemRequestedByValue events should be handled.
protected void ASPxComboBox_OnItemsRequestedByFilterCondition_SQL(object source,
ListEditItemsRequestedByFilterConditionEventArgs e) {
ASPxComboBox comboBox = (ASPxComboBox)source;
SqlDataSource1.SelectCommand = @"SELECT OID, [From], Sent, Subject
FROM (select OID, [From], Sent, Subject, row_number() over(order by t.Sent) as [rn]
from dbo.ServerSideGridTest as t WHERE ((t.Subject LIKE @filter) OR (t.[From]
LIKE @filter))) as st where st.[rn] between @startIndex and @endIndex";
SqlDataSource1.SelectParameters.Clear();
SqlDataSource1.SelectParameters.Add("filter", TypeCode.String, string.Format("%{0}%", e.Filter));
SqlDataSource1.SelectParameters.Add("startIndex", TypeCode.Int64, (e.BeginIndex + 1).ToString());
SqlDataSource1.SelectParameters.Add("endIndex", TypeCode.Int64, (e.EndIndex + 1).ToString());
comboBox.DataSource = SqlDataSource1;
comboBox.DataBind();
}
protected void ASPxComboBox_OnItemRequestedByValue_SQL(object source,
ListEditItemRequestedByValueEventArgs e) {
ASPxComboBox comboBox = (ASPxComboBox)source;
SqlDataSource1.SelectCommand = @"SELECT OID, Subject, [From], Sent
FROM dbo.ServerSideGridTest WHERE (OID = @OID) ORDER BY Sent";
SqlDataSource1.SelectParameters.Add("OID", TypeCode.Int64, e.Value.ToString());
...
comboBox.DataSource = SqlDataSource1;
comboBox.DataBind();
}
