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.

Forms Data Controls :: How To Access To A Label Value Inside Datalist In Update Statement

Jan 6, 2011

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...

Web Forms :: DataList Doesn't Update Without A Browser Refresh

Mar 20, 2010

I have a Shopping Cart Summary User Control that doesn't update without a full browser refresh.

The scenario is:

I have a DataList in one User Control that displays Product data with an ItemCommand event for an 'Add To Cart' button.

[Code]....

When the 'Add to Cart' button is clicked, the page reloads and another User Control containing the Shopping Cart Summary should be updating. However, the Cart summary doesn't fully update until a full page refresh occurs.

I should add, that the Cart Summary is "located" on a master page whereas the Product List is in the Content Placeholder of a web form based on the same master page.

I can provide more of my code if required but I'm initially reluctant incase I'm making a noobish error!

Forms Data Controls :: Update Dropdownlist With Detailview Control - Set Update Parameters?

May 10, 2010

I searched a lot of threads but still couldn't get my problem fixed. I have to update the "regform" table with two fields: session_ and session2. These two fields are inside the detailview edititem template which bounded to dropdown list drpsession1, drpsession2 separately. I wanted to pass the update parameters to the update sql UPDATE dbo.regform SET session_=@session_, session2=@session2 where id=@id

the @session_ is bounded to a drpsession1 and @session2 is bounded to drpsession2. I used
ControlID="ctl00$ContentPlaceHolder1$DetailsView1$drpsession1" to access the dropdown list within the detailview, but still couldn't do the updates. What's wrong with my code? Do I have to use the code behind to specify the update parameters? and How to do it? TIA.
