As I understand the datalist can display recordsets horizontally instead of just vertically or in a paginated fashion?
Is there any other data controls that can do this like a formview or does only a datalist have that capability?
I'm using a DataList to display photos in a TabSheet. The problem I get is that the div seems to get wider based on the # of pictures even though the pictures are not displayed and a scrollbar is.
[Code]....
I can't figure out what is causing this issue.
i have a datalist in my aspx like this:
<asp:DataList
ID="dlSubs"
runat="server"
CellPadding="0"
CellSpacing="5"
RepeatDirection="Vertical">...</asp:Datalist>
when i do this in the code-behind:
this.dlSubs.DataSource = dtCat; // dtCat is a datatable with about 13 rows
this.dlSubs.DataBind();
everything gets rendered in one column (vertical) but i want two colums... so i do this:
DataTable dtCat = shop.DAL.ArtikelenDB.GetLeftMenu(Convert.ToInt32(Request.QueryString.Get("catg")));
double tmpDouble = (double)dtCat.Rows.Count / 2.0;
double repRow = Math.Ceiling(tmpDouble);
dlSubs.RepeatColumns = Convert.ToInt32(repRow);
dlSubs.RepeatDirection = RepeatDirection.Vertical; // also tried without this line...
this.dlSubs.DataSource = dtCat;
this.dlSubs.DataBind();
but when i do the above. it gets rendered horizontally... how is that possible?
I am trying to work with vertical datalist but it is always displaying the items horizontally even after writing DisplayDirection="Vertical"

I am working on a project in ASP.Net, in which I am using DataList control to list the candidate data. As we know, DataBoud event is available for gridview control, which is raises after databound. In DataList control no such event is available. Yes, ItemDataBound event is there which is arises on every Item bound. Let us assume, that I want the number of items are listed in datalist, after completing the data bound of datalist.
View 2 RepliesI have a datalist and a hyperlink control that holds a url. A user creates this datalist through an admin website and not all of the hyperlinks have a link in them. The issue is how to hide the link that doesn't have a url in the database field.
code for the datalist:
<asp:DataList ID="dtlPromoEvents" runat="server" CellPadding="2" CellSpacing="2" RepeatColumns="1" RepeatDirection="Vertical" RepeatLayout="Table" >
<ItemTemplate>
<asp:Label ID="lblPromoHeading" runat="server" Text='<%# Eval("eventHeading") %>' Font-Size="12pt" ForeColor="#FFFF00" />
<br />
<br />
<asp:Label ID="promoDate" runat="server" Text='<%# Eval("eventDate", "{0:D}") %>' Font-Size="11pt" ForeColor="#33FF00" /> <span style="color: #33ff00; font-size: 12pt">@</span> <asp:Label ID="lblPromoTime" runat="server" Text='<%# Eval("startTime", "{0:t}") %>' Font-Size="11pt" ForeColor="#33FF00" />
<br />
<br />
<asp:Label ID="lblPromoDetails" runat="server" Text='<%# Eval("eventDetails") %>' Font-Size="11pt" />
<br />
<br />
<br />
<asp:HyperLink ID="eventLink" Text="Check this out!" CssClass="linkEvent" Visible="false" runat="server" Target="_blank" ToolTip="click to go check out what's happening!" NavigateUrl='<%# Eval("eventLink") %>' />
<br />
<br />
<br />
<hr style="width: 480px; height: 1px; background-color: #ff9900; border-color: #ff9900" />
<br />
</ItemTemplate>
</asp:DataList>
In the code behind I set the datasource with code and now I am stumped on how to reach into the items and control the visibility of the 'check this out' link based upon whether the db field has a link in it or not.
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dtlPromoEvents.DataSource = LoadEvents();
//filter through the events and turn on visibility for the events that have a live link.
dtlPromoEvents.DataBind();
}
}
public static DataSet LoadEvents()
{
DataSet eventInfo = new DataSet();
string connectionString = ConfigurationManager.AppSettings["ConnectBeerGeeksDb"];
using (SqlConnection selectConnInfo = new SqlConnection(connectionString))
{
SqlDataAdapter adapterInfo = new SqlDataAdapter("SELECT [eventDate], [startTime], [eventHeading], [eventDetails], [eventLink] FROM [promoEvent] WHERE (eventDate + 1 > GETDATE()) ORDER BY eventDate", selectConnInfo);
selectConnInfo.Open();
eventInfo.Clear();
adapterInfo.Fill(eventInfo);
selectConnInfo.Close();
}
return eventInfo;
}
Adding the refined code that works on this url: [http://beergeekspub.com/events.aspx][1]
protected void dtlPromoEvents_ItemDataBound(object sender, DataListItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
{
// Retrieve the Hyperlink control in the current DataListItem.
HyperLink eLink = (HyperLink)e.Item.FindControl("eventLink");
// Check if a URL exists, if not then hide the control
if (string.IsNullOrEmpty(eLink.NavigateUrl))
{
eLink.Visible =false;
}
}
}
also the page load databinds the datalist -
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
dtlPromoEvents.DataSource = LoadEvents();
dtlPromoEvents.DataBind();
}
}
My question is dealing with the DataList control. I am trying to add a click event to the rows of the "table" in the OnItemDataBound event.
The problem I'm having is I can't get a reference (through a row id attribute) to the "row" being generated by the DataList control (and more specifically the item template). Is there a way to add id attributes to the rows being generated by the item template?
I have created a Linq Function and want to bind with DataList control but getting and error below is Error and code

Prior to adding paging using PagedDataSource I had dropdownlist and search box filters for my DataList. The guts of the code in aspx page for those parameters is below:

ConnectionString="<%$ ConnectionStrings:ConnectionString %>"

When creating the pager using PagedDataSource I did a tutorial which did not have parameters and all the code went in the code behind page. The guts of it is below:
private void BindGrid()
{
string sql = "SELECT [ProductCode], [ImgUrl], [Featuring], [Title] FROM [TableSG1] DESC";
[code]....
The pager is great but now I need to add my filters. The page wont load if I add the "SelectParameters" code (above) to my aspx page and if I simply add the "WHERE" clause to the "SELECT" clause in the code behind I get an error stating that I need to add a scalar variable.
I have found some examples through googling but nothing specific enough.
