While working with SharePoint 2010 Grid view grouping
depending on dropdown value, got an error saying that “Value cannot be null.
Parameter name: Container” as shown the image below.
Iam unable to find the issue while debugging the code. I
have spent much time on this issue finally got the reason. By making “EnableViewState” to false error
got fixed as show the code below.
grdPropertyValues.EnableViewState
= false;
grdPropertyValues.AllowSorting
= true;
grdPropertyValues.AllowGrouping
= true;
grdPropertyValues.AllowGroupCollapse
= true;
Here grdPropertyValues is SPGridview object. Hope this
helps.
