Hello Eric,

Yes, you were correct. Instead by using HiddenField, you can also use SendCustomRequest() and AddInput() via script to send data to server. You can access it the data in InitializePostBack server side event.
Actually, it would be too much effort if you disable the cache. In WebGrid 7, it has new feature called Batch Update. All the changes would not be saved until we accept all the changes. Event though we already used accept changes, we still can interrupt it in OnBatchUpdate server side event.
All the changes in cells can be seen in changes collection. This feature can work well without caches.

Hello,

It seems based on your WebGrid, table is not the correct element. It easier to get it directly from WebGrid element. You can try to find the proper location that you want to place the text for sum of items.

e.g grid.GetElement(WG40.STATUSBAR, WG40.HTMLCELL);
This code will let you get the element of "Ready" in status bar. You may able to go to its parentNode or perhaps add new <td> to easier to mantain layout information for your status bar. Hope this helps.

Hello Eric,

I could not modify your sample because I don't know much about what kind of save or code that you wanted to call.

if(Sum==10.0) 
{
			//do save here
			//How do we get the data in the grid???
} 
else 
{
			//cannot save, Sum must be 10.
}

So, basically how to save data is something that you need to take care of. I can only show how to get data in grid.

E.g I added a hidden field to your sample, named sum. 

function Table_ExitEditMode(controlId, tblName, editObject) 
{
	var cell = editObject.cellElement;
	var inp = editObject.element;
	var col = wgGetColumnByElement(cell);
	var row = wgGetRowByElement(cell);
	var sum = document.getElementById("HiddenField1");
	switch (col.Name) {
		case 'Weight':
			if (IsValidPercentage(inp.value)) {
				var grid = ISGetObject(controlId);
				var grandTotal = 0;
				for (var i = 0; i < grid.TotalRows; i++) {
					// Note: The unary '+' is to convert the string into a number.
					if (i == row.Position)
						grandTotal += +inp.value;
					else
						grandTotal += +grid.RootTable.GetRow(i).GetCells()[col.Position].Value;
				}
				// column footer
				var NumInvisibleColumns = GetNumInvisibleColumns(grid);
				grid.RootTable.GetElement(WG40.COLFOOTER, WG40.HTMLTABLE).rows[1].cells[col.Position - NumInvisibleColumns+1].innerText = grandTotal.toFixed(2);
			} else {
				// not a valid percentage
				alert('\'' + inp.value + '\' is not a valid percentage!');
				inp.value = cell.OldText;
				
			}
			break;
	}
	sum.value = grandTotal;
	return true;
}

 
After you use PostInputControls to true, you should be able get the data in postback/server.
In your idButton_OnClick, you should able to access the value by using hidden field id.

Hello Michael,

Allow me to help you answer the question one by one.

1. Silverlight class library
Today I've worked with ClientUI MVVM Data Application template. The structure of the generic base classes is great! The only downer is that partly text messages (e.g. MessagePresenter) are hard coded!

Unfortunately it is not possible (I did not manage) to move the dictionaries ModelServices.Infrastructure andViewModels.Infrastructure in a Silverlight class library. In the Silverlight Class Library, I can not reference the assemblyIntersoft.Client.Data.ComponentModel. Is there another way to increase the reusability?

Is probably a mistake in MessagePresenter.cs:

public void AskYesOrNo(string question, Action yesAction, Action noAction)
{
    MessageBoxServiceProvider.Show(
        "Are you sure you want to delete the selected contact?",
        "Confirmation", MessageBoxButton.YesNo, MessageBoxImage.Question,
        dialogResult =>
        {
            if (dialogResult == DialogResult.Yes)
            {
                if (yesAction != null)
                    yesAction();
            }
            else
            {
                if (noAction != null)
                    noAction();
            }
        });
}

better is:

MessageBoxServiceProvider.Show(question,"Confirmation", MessageBoxButton.YesNo,MessageBoxImage.Question,

Hello,

Our developer tried hard to make it better. Please try to use attached hotfix. Also, it seems, it needs to call twice SetHeight() method.
