Hello,
I have successfully implemented a custom provider for RadSpreadsheet following the example here: http://www.telerik.com/support/code-library/spreadsheetdatabaseprovider.
I would like to be able to update a RadLabel on the same webform with some data derived from the saved sheet (for example, the count of rows). I have passed a reference to the RadLabel into the constructor of the custom provider and am setting it there:
public class PerformanceSheetProvider : SpreadsheetProviderBase
{
private readonly RadLabel _resultLabel;
public PerformanceSheetProvider(RadLabel resultLabel)
{
_resultLabel = resultLabel;
}
public override void SaveWorkbook(Workbook workbook)
{
_resultLabel.Text = workbook.Sheets[0].Rows.Count.ToString();
}
...
However, the RadLabel value is not updated. I have also tried refreshing the update panel in which the label is contained in the client-side override of _onCallbackResponse:
Telerik.Web.UI.RadSpreadsheet.prototype._onCallbackResponse = function () {
$find("<%= RadAjaxPanel2.ClientID %>").ajaxRequest();
}
...but the label is still not updated.
Any suggestions?
Thanks!
