Forms Data Controls :: Access Datalist Control From Code Behind?

Jul 22, 2010

I want to access my checkbox in code behind. I have my checkbox in my aspx file like this:

[Code]....

And i'm trying to set the checkbox visible=false like this but it's not working. Error message: Object reference not set to an instance of an object.

[Code]....

This is just one thing i want to do with my controls in my datalist, so i don't want to in my aspx file like this:

<asp:CheckBox ID="CheckBox1" runat="server" Visible='<%# if(Eval("isFolder")="1","false","true") %>' />

Because i have quite a lot of things i would like to do in the code behind when i'm getting my files..

Is it possible somehow to achieve this without having to put servercode in my aspx file?

Web Forms :: Scroll To Certain Datalist Item At Pageload?

Aug 27, 2010

I'm creating a forum and the forum posts are items in a datalist.

Now I want to include the nifty feature that when one has replied to a message and the forum thread page is being displayed, the page is autmatically scrolled down to the message one wrote (the same thing goes for linking to a message, one wants the page to be scrolled down to the right place from the start).

I guess this could be done using anchors an html, but is there a function i vb.net that would do this for me?

Forms Data Controls :: Programatically Access The Link Of A DataList?

Jun 23, 2010

I am writing a system that is input intensive, and the used need to be able to use without touching the mouse. I am trapping the enter key and defaulting to click an "Enter" button that I have on the screen. In the EnterButton_Click event, I am using a "menu option" to determine which DataList item they want.

All of that is working great, except reading back the URL from the DataList Item, which I need for my repsonse.redirect to call the next screen.

[Code]....

I am inches away from pulling this off.Entire code is below. The actual datatable/datasource will come from a file later, I just mocked up some links for this example.

Forms Data Controls :: Access Data That Is Outside A DataList And Insert It Into A Database?

Feb 2, 2010

I can't seem to access a label that is outside the DataList. I wish to add the data in the label into a database, aswell as data that is inside the datalist (this is already working though). My SQL-query with only the specific label looks like this at the moment:

[Code]....

The data is added to the database when pressing a button inside the datalist (using onItemCommand). If I write UserIDLabel.Text the regular way it doesn't work either. The label is in the MasterPage, while the datalist is in a .aspx-page. If it is possible to somehow access the data that is in this label and add it to the database I would be ever grateful. Or is it somehow possible to add data that is in a Session and add it to the database?

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 :: Access Querysting Values From Masterpage's Pageload Method?

Mar 25, 2011

I access querystring values in each content page's pageload method to get Username and Id. Is there a way I access the querysting values from Masterpage's pageload method and each content page goes to Masterpage to get those values without creating any other local variables in content pages? I know this can be done with Session's or view state but I was thinking to reduce redundancy of accessing query string in each content page.
