Hi,

One of my report parameter has a single column data source and empty value in the first row. Both AllowBlank and AllowNull are true on this parameter. But the empty value is not showing after run. Using firebug, i found that empty listviewitem exists there but not showing(Report1.png). When i wrote something in listviewitem by editing html element in firebug, it appears(Reprt2.png). I need to filter using empty value because the report data source contain empty values in some rows. Now only way i have to filter using empty value is, first, click the 'Select all' on the parameter and then deselect other values one by one so that empty value keep selected and Click 'Run Report'. But it is not the right approach to do. As AllowBlank is true, empty/blank should visible & should be selectable/deselectable? 

Please give a solution on this.

Hi Sabbir,

Report parameter that has available values will be displayed in HTML5 Report Viewer by Kendo UI listview widget and null values retrieved from parameter's AvailableValues.DataSource will be ignored.

If you need to filter the report's data using an empty value you can specify it in the filter expression, for example:
= Fields.MyField Is Null Or Fields.MyField = ""

Hope this information will help.
