Forms Data Controls :: Batch Update In A Datalist?
Jan 4, 2010
I have a datalist and it contains a checkbox bound to a boolean value. I need to be able to scroll through the list, click on the appropriate checkboxes, and then update all using the button control. The only value in the sql table that needs updating is the checkbox, although other values are displayed. What is the simpliest way to do this. My code behind is C#. This is what I have now and it all works except for the actual update method being called correctly.

In code behind my click event:

I am using asp.net 3.5 c#. I am trying to do this:
In one page, a user can insert some stuff (name, phone .. etc) to the database. And then the user should be able to see the rows he added as a list automatically in a datalist (or other control). As he inserts rows, it appears in the datalist.
I tried to use update panel and inside it datalist, with a button as a trigger but it did n't work with me!

i have the code to test:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =8", Con)
Now, I need something like this:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" + LblInfoEditar.text, Con)
The problem:
The LblInfoEditar is outside the datalist so it works fine. (note: in this label I put a value like the 8)
But I have this label to test because I need to access a label inside datalist:
<asp:Label Visible="false" runat="server" ID="LblNumEntrevista" Text='<%# Container.DataItem("EntrevistadoCodigo") %>'></asp:Label>
The problem is: in this line I've to put something to access this LblNumEntrevista HOW?
I try:
Cmd = New OleDbCommand("update TabEntrevistado set EntrevistadoConcluido=true where EntrevistadoCodigo =" +
ListaPendentes.LblInfoEditar.text, Con)
But of course I don't work because I can't do this...

I have a set of data that has been displayed as just a simple GridView with the item name being a hyperlink to view details. I'm attempting to update this scenario so certain fields (sortOrder and isApproved) are editable from the main page and do not require visiting each item in the grid. I have converted the GridView to a DataGrid and have included a TemplateColumn for the columns in question. I have them hooked up to display the values appropriately. At this point, I'm trying to find a way to peek into the DataGrid and it's related data source to determine if the values have changed on the click event of a button. At that point, I could persist those changes back to the respective SharePoint list.
I'm not very familiar with the DataGrid, or GridView for that matter. Can anyone point me in the correct direction on how I could gain access to the data source at an item/row level during a button click event where the button exists outside the context of the DataGrid?
