Hi Mark,

    If I am not mistaken, you are trying to load all the records and check all the checkboxes in classic paging ?

    Here are some information about classic paging. In classic paging, the data will be rendered per page.  So, if we like to check all the checkboxes, we need to load the data per page and do check them. Also, in classic paging, the cell template of checkbox will be reset after the WebGrid is refreshed or go to the next page, so we will need to use a data that consist of boolean type value and change it into a checkbox. 

    Here is a snippet to manually check all the checkboxes in WebGrid by rendering it page per page. As you might try, we will have a difficulty in setting update row of the WebGrid. That is why, in my snippet, I only use 5 rows per page. So ensure before you try the code, you have already changed the setting of your classic paging with 5 rows per page. And also, in here, the checkbox column's name is "Discontinued". So, to check if the checkbox is checked or not, we can simply set the value into true or false.

        function Button1_onclick()
        {
            var i = 0;
            update(i);
        }
        function update(i)
        {
            var grid = ISGetObject("WebGrid1");
            var row = grid.RootTable.GetRow(i); 
            var cells = row.GetCells();
            row.Select(); 
            cells.GetNamedItem("Discontinued").SetText("true", true); 
            setTimeout(function()
            {
                row.Update(); 
                i++;
                if (i < grid.GetRootTable().GetRowsCount())
                {
                    update(i);
                }
        
                if (i == grid.GetRootTable().GetRowsCount())
                {
                    setTimeout(function()
                    {
                        grid.GotoNextPage();
                        i=0;    
                        
                    }, 400);
                    setTimeout(function()
                    {
                        update(i);
                        
                    }, 1000);
                }
            }, 400);
        }

      I hope it helps and please do not hesitate to ask if you have any other questions. Thank you.

Hi Andi,

Thanks for the reply. I decided another way to implement this was to change the paging mode dynamically so that I basically refresh the grid and set:

.PagingMode = PagingMode.None
.StatusBarVisible = False

Then I wait on the client for the grid to reload and walk through all the rows setting the checkbox on. Seems to work really well.

Regards,

Mark
