Hello Handy ,

   Thank you for your method . I have used this method to get the total number . However , I hope sincerely you can provide the interface (or the attribute or the method ) to get the total number of WebGrid in the next version . Then we can work more easier .

Hello Handy ,

   I find the WebGrid can display the total number When I set  PagingMode="VirtualLoad" in LayoutSettings . You can see the result from the picture in attachment file . Why ? How the WebGrid get the total number from database ?  Did you tell me there is no way to get the total number ??

  Besides , When I use IsDataSource , I must write the method of SelectCount in the Bizlogic file . This method return the total number of items of WebGrid . What is the function of this method ?

 I want to get the sum of the items of webgrid and I want it to show in the status bar in this simple sample . I believe it's easy for you .Really looking forward to your great help .

 I use "iframe" . WebTreeViewis on the left and WebGrid is on the right. When I click the nodes of the tree , the WebGrid on the right should be changed ! it work smoothly in the IE .
