How do you databind from an AccessDataSource to a Label Control on page_load? I know you can use eval, but how do you associate your eval statement with the correct data source control?

which works great for the FormView in the aspx page.I would now like to use this datasource (or create something similar) to bind one of the column values to a label's Text attribute.Totally stuck here -- i understand i cant explicity bind to a Label as I could a dataview, etc, but i should be able to set the label1.text value using a datasource from the code-behind.
i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.

Is it possible to access the value of a label and want to tweak it before it to textbox which is in edititemtemplate column.
<ItemTemplate>
<asp:Label ID="lblUnitprice" Text='<%# FormatPrice(Container.DataItem("UnitPrice")) %>' Runat="server" />
</ItemTemplate>
<EditItemTemplate>
<asp:Textbox runat="server" CssClass="TextBoxes" MaxLength="14" Columns="8" id="UnitPrice_edit" Text='<%# FormatPrice(Container.DataItem("UnitPrice")) %>' />
</EditItemTemplate>
Used onprerender a lot with dropdownlist boxes never used with textboxes.I have two currencies used in my application, want to format before i show to use.
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 column that I don't want to display but I still want to access its value. the other problem is that I can't access the value of a cell because it contains a label. Does someone know how to access the text in that label?

I have gridview in my page that users can edit their data in gridview... and in this gridview I define label that I want when users click on Edit button it change label3.text:
below is code:

AutoGenerateColumns = "false" Font-Names = "Tahoma"

GridLines = "Both" OnRowDataBound = "OnRowDataBound"

And .cs:
protected void EditCustomer(object sender, GridViewEditEventArgs e) {
Label Label3 = (Label)GridView1.Rows[e.NewEditIndex].FindControl("Label3");
Label3.Text = "neda";
GridView1.EditIndex = e.NewEditIndex;
BindData();
BindData1();
}
but here when I click on EditCustomer it doen't change label3.text
I have a button on a page with a Repeater and an ObjectDataSource. To give credit where credit is due, the Repeater's paging functionality is courtesy of ScottGu. (However, I'm using ASP.NET 4.0 and SQL Server 2008, as opposed to ASP.NET 2.0 and SQL Server 2005.)
Anyway, in the button's click event, I need to access the Text property of a Label that's inside the Repeater because it's used as an input parameter in a stored procedure. I'm getting a NullReferenceException when trying to access the Label's Text property. I have researched this error and have tried a few different solutions (involving FindControl and the Repeater's ItemDataBound event), but I haven't been able to get it to work. The code is below.

I have a class (name PageBase) that is inhariting System .Web.UI .Page and all my .aspx page behind classes are inhariting this class. This way I have put some common things in PageBase class.
For showing errors I want to put showMessage funtion in PageBase as well so that I may have not put it in every page and it will easy to manage this way.
Probem is that how PageBase class will access a control which is in aspx page in its child class (child class of PageBase) .
I dont want to pass control as argument to function in parent class, is ther any other way ?
I would like a title label to only be visible if the bound data label is not empty.
<asp:Label ID="TitleLabel" runat="server" Text="Title:" /> <asp:Label ID="DataLabel" runat="server" Text='<%# Bind("Data") %>' />
So if there is no Data incoming to the DataLabel then I want both labels to be invisible.
