What I'm trying to do is on page load display either of two controls based on how many items are in a datalist. For instance, if the datalist only contains 1 item I want it to display
Literal1.Visible = true;
If there is more than 1 item in the datalist, show
LiteralMulti.Visible = true;
Anyone know how to do this?
IÂ am trying to work with vertical datalist but it is always displaying the items horizontally even after writing DisplayDirection="Vertical"

I have successfully implemented article - "Print only the items which are selected using checkbox in a ASP.Net DataList control"
I would like to add a dropdownlist above the DataList Control to filter the contents of Datalist and then print the items selected using Checkbox in a ASP.NET DataList Control.
When designing an ASP.NET user control my standard way for creating say a details view would be to create a property of the desired type on my page and would set the property in the page load based on the supplied query parameter. I feel I'm probably doing more work then necessary. If I could encase my view inside a container then I could merely have it databound and thus make everything declarative.My question is what would be the lightweight container/controls that would be appropriate for databinding a single object?As a second question, how can I handle invalid query strings with this method?

I want to implement an image gallery in asp.net/C#. I am using sql server 2008, visual studio 2010 and .NET 4.0.
I have made a webpage and now want to display 6 images as thumbnails (and their names just below the thumbnails) at the center of the page. The format of the display is something like this:
[Code]....
Basic operation is like this:
I pull images from a database and then display them as above as thumbnails. The 1 2 3 Next> are links depending on whether there are more than 6 images pulled from the DB. So basically the numbering 1 2 3 4 Next> is dynamic depending on how many images exist. Can anyone give me a basic overview of how this an be achieved? Should I be using a asp:Repeater or a asp:DataList for this kind of a display?
I've been trying to figure out for a long time now how to create an interface that can allows users to input several rows of data and pass those entries into an SQL server database all in one shot. I could not get any better ideas so I came up with this (see picture below).
What I envisioned is that the user enters values in the textboxes and hits the "add to list" button. The values are then populated in the list box below with the heading "exhibits lists" and when the add exhibit button is pressed, all values from the list box are passed into the database.
Well, I'm left wondering again if it would be possible to tie these values from the textboxes to the list box and whether I'd be able to pass them into the database.
how to go about it otherwise I'd be glad if you could recommend a better way for me to handle the situation otherwise I'd have to resolve to data entry one at a time.

I'd like to create a new server control to use in my project. Basically, it should work and behave in exactly the same way as asp:TextBox except that the type attribute on the HTML input element it generates should not be "text" but a different value (I actually intend to create several controls for several different type attributes).
So (by the way I have very little programming experience), I'm thinking I need to get the source code for the asp:TextBox control and base my new control on that, then modify the source so it outputs with my desired type attribute.
Can anyone steer me in the right direction for this?
I have use composite custome control its contain button and textbox and gridveiw
but design time gridview is not display .
For example in my datalist if Eval("OptionJ").Tostring = Null I would like the function GetVisible to set visibility of the radio button to false like so:
<input name="Q<%#Eval("ID")%>" type="radio" value="J" visible="<%# GetVisible(Eval("OptionJ").ToString()) %>">
<%#Server.HtmlEncode(Eval("OptionJ").ToString())%>
</option><br />
I then have a codebehind function like so:
Protected Function GetVisible(ByVal Evalresult As String) As String
If Evalresult = Nothing Then
Return "False"
Else
Return "True"
End If
End Function
I have also tried checking EvalResult = String.empty
In the outputted html the visible status is being set to false...
<input name="Q3" type="radio" value="J" visible="False">
But it is still displayed on the page!
I have a datalist, this datalist control is bind, when user select control filters,i am looking a way to sort this datalist control for example like asc or desc or price.Â
