Hello Xu,

I am able to replicate your issue on my end. I think you should to add 1 line of code to syncdhronize pending changes with grid's user interface elements. Please add this snippet code to your SelectAllColumn method.

grid.UpdatePendingChangesStatus();

You can also add the snippet code above to OnCheckBoxClick WebGrid's clientSide Event to do same response when some checkBox clicked.

Hope this helps.

Hello Riendy,

    Firstly , thanks for your reply and help . I have tried to use the two methods you recommended ,but there is not any changes at all . when I select the checkbox of the column header , all checkboxs of this column will be selected , but the icon colors of accepting all changes or undoing all changes in the footer of the webgrid  is gray . I think this indicate I did not make any changes in this webgrid .

   In the attachment file , there is a simple example based on the live example of Intersoft Solutions . So can you help me to solve this problem ? I will be very grateful !

Hi Xu,

I'm still investigate your issue. I will let you know as soon as possible about this issue. This issue might be a bug.

Anyway, to initialize WebGrid, I suggest you to use ISGetObject. So, you are able to use our method, such as UpdatePendingChangeStatus. For example : 

var grid = ISGetObject("WebGrid1");

Hello Riendy ,

   Thank you for your help . I want to know whether there is the newest development about the issue I put forward . Because I have to use the function that I have raised in my project , I am looking forward to your respond eagerly .

  Thanks a lot !

Hello Xu,

Actually there is no bug with your issue. At the beginning I've told you that you have to add UpdatePendingChangesStatus(). I'm sorry because I missed a method to add the pending changes. It is   AddPendingChanges() method. I have created the snippet code based on your scenario. Here is the snippet code: 

  function SelectAll(obj) {
            var grid = ISGetObject("WebGrid1");
            for (i = 0; i < grid.TotalLoadedRows; i++) {
                grid.RootTable.GetRow(i).GetCells()[0].SetValue(1, true);
                grid.RootTable.GetRow(i).AddPendingChanges();
                grid.UpdatePendingChangesStatus();
            }
        }

I also have modified your simple runable sample to reproduce in WebGrid's sample easilly. Attached is a sample file.

Best Regards.

Hello Riendy ,

   Thank you for your reply ! Are you sure the sample file you provided is correct ? I find the sample only have WebComb and ISDataSource , and it is not the same as the sample I have provided .

   Besides , I have tried the method you put forward . When I click the checkbox of the header column and select all checkboxs of this column , I click the icon of accepting all changes  in the footer of the webgrid , then an unhandled exception occur . It said "To analyse in this string ,  it must specify effective information" .

   Can you give me an integrity sample ?  When I click the checkbox of the header column and select all checkboxs of this column , then I can click the buttons of WebToorbar and execute some operations , such as add or delete or save . Then I can do my work referring to your sample .

  Thank you very much !

Hello Xu,

First of all, sorry for the wrong sample that I attached. Yesterday, I have not tried until accepting all changes. So, I also get that issue here. 
I have provided a solution using this snippet code:

function SelectAll(obj)      
      var grid = ISGetObject("WebGrid2");
      for (i = 0; i < grid.TotalLoadedRows; i++) {
          var row = grid.RootTable.GetRow(i);
          var cell = row.GetCells()[3];
          cell.SetValue(true, true);
          cell.ActivateEdit();
          grid.MarkEdit();
          grid.ExitEdit(1, 0, 0);
       }
}

Attached in my simple runable sample. In this sample I also show you how to un-check all checkBox.

Please let me know whether the issue still exist, or if there is another issue.

Thanks.
Riendy
