DataGrid Edit - (TextBox)e.Item.Cells[3].Controls[0].Text returns old value

I have a DataGrid that lists items from a hardware catalog. Having edited the price of an item and selected update, the InventoryGrid_UpdateCommand()  method reads the price into a textbox: TextBox Price = (TextBox)e.Item.Cells[3].Controls[0];. The problem is that it seems to be reading the original value not the value I have entered. Any ideas?        


<asp:datagrid id="InventoryGrid" runat="server" width="536px" bordercolor="Silver" borderwidth="1px"

How is it that u are editing the Price whn u have it in a BoundColumn. Change that into a TemplateColumn and have ItemTemplate and EditItemTemplate inside them to make this work.

<asp:TemplateColumn HeaderText="Price">
         <%#String.Format("{0:C2}", DataBinder.Eval(Container.DataItem, "Unit_Price"))%>
         <asp:TextBox Runat="server" Width="120" Text='<%#DataBinder.Eval(Container.DataItem, "UnitPrice")%>ID="tbxEditRemarks">

in the code behind

TextBox Price = (TextBox)e.Item.Cells[3].Controls[1];

woud get u the value in the textbox.

Spot on. Big Smile [:D]

Believe it or not I realised I must have done this when I was on my way home last night.

My bound Price column is dynamically changed to a text box, I believe it must be a feature of the DataGrid.

Thanks for the help

What is the difference between e.Item.Cells[1].Controls[0] and e.Item.Cells[1].Controls[1] ?

Thanks a lot ! briefly a DataGrid is rendered as an HTML Table containing TR ( item ) and TD ( cells ) elements at runtime e.Item.Cells refer to the TableCellCollection in the current row this cells collection, like any collection in .NET, is zero-based, meaning the first cell in the Cells collection is Cells [ 0 ], and the next is Cells [ 1 ], etc. e.Item.Cells [ x ].Controls refer to the control collection within the cell.

Returning value from composite control to more than one other controls
This is not really a problem but I was curious if there was a better way to do this. I have a Composite Control that will return its value to a server control or something when it is done. I expect that it will fill a text box or a label but I wouldn’t mind if it could fill a button or any number of things that have a simple place to store text. Is there a better way than going through all of the option by hand?   Here is an example of my code.   public class DateTimeThing : CompositeControl    {        protected DateTime dateti...

Application created in new version of .NET (3.0 or 3.5) can use the library created in older version of .NET(i.e.-1.0 or 2.0)?
Hi All, I am using Visual Studio .NET compiler for compiling my application . We have plugins (as library) which the user can write by their own in .NET . We are building our code in Visual Studio 2005 but we have already some plug-ins which are written in previous versions of Visual Studio (i.e. 2002 and 2003). Is these plug-ins will work with the new build of the application or I need to build these plug-ins as well in Visual Studio .NET 2005. These plugins are created as library. Is their any differences between .NET 1.0, 2.0 and 3.0 because of which the old libraries (created in o...

Control.Value and Control.SelectedItem.Value
Can someone explain to me the difference between say, Dropdownlist.SelectedItem.Value and Dropdownlist.SelectedValue??

If that is all you want then you can just use that. If you want to access the currently selected item you can use dropdownlist.selecteditem and that return the item and you can then access any of the item's properties, including in this case the value property. If this post answered your question please r...

Return in a Edit Item Template text box to cause the Edit Command button to click in a DataGrid
Hello Everyone I have a DataGrid with ItemTemplates.  What the client wants is to be able to hit return in the edit item template's text box, and as a result have the Edit Command Save button clicked. Doing a search I came across several discussions of this topic that indicated that one could do this using JavaScript, but I'm unclear about how to go about this; I'm guessing that I can trap the key press in the box and cause a postback if it's the return key but don't know what event I'm looking for. Suggestions?   Thanks in advance! I am assuming that there's only one save b...
