I have to filter an XSLTListViewWebPart using 3 TextFilters and one ApplyAllFilters button. With SharePoint Designer, I create 3 parameters with the filter 'Contains',then I'm filtering the DataView with these params and finally I apply the connections
to the DataView from Connection Manager. I need to filter the DataView with any one of the TextFilters and also I want to have the ability to filter the DataView with 2 or all the TextFilters using 'AND' clause to give me the results on the XSLTListViewWebPart
on the same page.The problem is that the 'AND' condition on the TextFilters makes them required to have one value given to them for search, a thing that I don't want. Thank you.
